CHAPTER 1 Introduction to Services and Schedules

SCS Computer Support Center (SCSC) Services

The SCS Computer Support Center, formerly called the Help Desk, is located in the Computer Building (050) Lobby and is the primary user interface to the services of SLAC Computing Services (SCS). The SCSC can help find answers to your computing questions, help resolve problems, coordinate and support computing resources for large collaboration meetings, assist with using the public printers, PCs, transparency and copy machines in the Computer Building Lobby. In addition, the Help Disk will:

During FY94 the Help Desk processed 14,000 service requests of which 1,000 were trouble calls, 600 requests for installations, and 1,000 for modifying or opening new accounts.

Schedules

Computer Support Center Schedule

SCSC assistance is available 24-hours a day, seven days a week. How to best reach SCSC assistance depends on the time of day, day of week, and the urgency of your question or problem.

Numerical Analysis (NA) Consulting Schedule

NA consulting is provided by Stanford students and varies from quarter to quarter. For the current schedule, enter the VM command: type nahours memo * or look at the UNIX file /usr/local/doc/intro/nahours.

VM Batch Schedules

There are two schedules for the VM batch system: SKED1 and SKED2. SKED1 favors execution of classes X, S, M, and N, while SKED2 favors the larger classes L, J, and Z. SKED1 is in effect from 7:10 am--5 pm; SKED2 is in effect at all other times. Batch classes are defined in the VM file BATCH CLASSES *.

Central Computer Outages

Scheduled system outages are necessary for preventive maintenance and software or hardware changes. This type of outage is scheduled 24 hours in advance and announced in Netnews group slac.computing.outages. If the impact is too severe, contact the person whose userid is given in the outage announcement. Exceptions to this are occasional system crashes and other problems that severely impact services. If an emergency outage must be taken, SCS will provide online notification if possible.

CHAPTER 2 Support for Trouble Calls and Installations

Within the scope of this area of service, the SCS Computer Support Center:

The SCSC staff is relatively new to this service area and is still acquiring the expertise necessary to achieve their standard of service. They will greatly appreciate your patience while building their expertise.

Placing a Trouble Call

If you are experiencing a problem with your computer, you do not have to determine first whether it is a problem with the network, the hardware, or the software. Simply contact the SCSC by phone, e-mail, or in person (see Table 1) and describe the symptoms of the problem and give any other information requested. The SCSC person will help you directly if possible, or route the problem to an appropriate person within SCS.

The Desk attempts to adhere to a 2-hour turnaround on trouble calls. That is, if they have not solved the problem or determined the cause of the problem and an effective solution that can be implemented at the end of two hours, the problem will be escalated to the next more expert level.

The SCSC encourages you to call them when you experience problems with any onsite or offsite network problem. If the problem is with an offsite network, they will contact the other end if necessary and try to resolve the problem. Communications are likely to be more effective when the technical experts from SLAC and the other end are involved than when SLAC users, who are not likely to be trained in network details, try to pinpoint the problem.

Network Connections and Workstation and PC Installations

To avoid delays in having workstations, PCs, printers, and other computer-related equipment installed and connected to SLAC's network, the SCSC strongly encourages you to request installation as soon you have ordered the equipment. The location where the equipment is to be installed must be cabled with Ethernet cable. To check whether the location is already cabled, look for a gray cable with an orange tag (there may be a second tag near it). Note the numbers written on the tags because you will need to supply them when requesting installation and on the SLAC Nodename and Address Request Form (see below).

The SLAC network consists of the both public and private networks. SCS supports and maintains all SLAC public networks; private networks are funded by individual SLAC groups which control access, but are maintained by SCS. If you wish to have your equipment connected to a private network, contact the SCSC for installation. You will need to state the network name so that Network Operations can check your request for validity and queue your request.

Follow these steps to get your equipment installed and connected to SLAC's network:

  1. Send a copy of the purchase requisition to Teri Church, Manager of SCS Network Server Technical Support, M/S 97A. Follow the procedures given in UNIX file /usr/local/doc/how-to-order/xstation or the VM file XSTATIONS ORDERS * for selecting and purchasing an X-terminal.
  2. Call the SCSC (see Table 1) to initiate installation and maintenance.The SCSC can also assist you with the network/cabling needs and arrange for any accounts which may be needed.
  3. Acquire a UNIX or VMS account if you need and don't have one ( see section "Computer Account Authorizations" on page 6 for details). All networked workstations, PCs, and printers must have a name and Internet address to send and receive data and messages. A nodename is the name of any computer, terminal or peripheral on a network. Guidelines for choosing a nodename are given on the back of the form. The IP address is used for moving data between physical networks.(1)
  4. To change the present nodename and IP address or acquire a new one for the equipment, fill out a SLAC Nodename and Address Request Form available at the SCSC and online(2) .
  5. The form will need to be signed by a group leader, group czar or another person designated by your group leader.
  6. Send your completed form to SCS Computer Support Center at M/S 97, fax it to (415) 926-5400, or return it to the SCSC. You will be notified by e-mail when your network address has been assigned. If you don't have a computer account yet, the information will be mailed to you through interdepartmental mail.
  7. Notify the SCSC when your equipment is ready for installation. For X-terminals follow the last step in the procedures described by file /usr/local/doc/how-to-order/xstation or the VM file XSTATIONS ORDERS *.

CHAPTER 3 Computer Account Authorizations

Use the SLAC Computer Account Form, available at the SCS Computer Support Center in the Computer Building Lobby, to request an account on the VM, VMS, and UNIX systems. Also use it to change and cancel existing accounts and to request additional accounts.

Use of the Macintosh e-mail system QuickMail and Apple Remote Access (ARA) to connect from a Macintosh at home to the SLAC network requires authorization via e-mail (see below).

UNIX, VM, and VMS Accounts

Opening, changing, and canceling accounts will require the signature of your group czar. Important! On the SLAC Computer Account Form, be sure to indicate the system to which your request applies and have the form signed by an authorized czar. If you do not know the name of the czar(s) for your group, call the SCSC; or if you have access to VM, enter the command:

binlist auth your-group-code

(e.g., EY, SF, TH). Any of the named individuals can sign the request. If the group code of your account changes, the authorized czar of the new group will need to sign your change request.

Requests for secondary or additional accounts on UNIX and VMS are discouraged and require the SCSC to obtain special approval from SCS. You will need to indicate the request for a secondary account in the Additional Instructions section of the form.

After you have completed the form and signed the Computer Account Responsibilities portion, bring, fax to (415) 926-5400, or mail it to the SCSC, Mail Stop 97. The SCSC will process your request within 1-2 working days after receiving your completed Computer Account Form and send you information about the request through interdepartmental mail (or US mail if the request came from offsite).

If your request for establishing or making changes to an account is urgent, the SCSC will try to expedite it. You will need to come to the SCSC to pick up the appropriate account information after the request has been processed. To meet security requirements, you will need to show an id before the information will be given to you.

Notes on the SLAC Computer Account Form

CAD UNIX means that your home directory will be the CAD directory. CAD UNIX accounts are usually reserved for members of group MD. Users from other groups wishing a CAD UNIX account will need special approval from one of the CAD czars and their own group czar.

Unix Other means that you need a specific home directory. Indicate the name if known under 'Additional Instructions', i.e., Mojave or Reason Cluster. Mojave is reserved for SSRL users and requires approval from the SSRL czar. To get an account on the Reason Cluster of NeXT machines requires approval from Paul Kunz.

VAX. If you need a VAX account on SLACVX, you must be sponsored by one of these groups: EY, EK, BJ, and SCS. If you need assistance with getting a sponsor, contact the SCSC.

Forgotten Passwords

If you have forgotten your password, come to the SCSC. You will be told your password after you have shown your id. Offsite users must contact their group czar for assistance.

Apple Remote Access (ARA) and QuickMail Authorizations for Mac Users

ARA allows a remote Mac (for example, your Mac at home) to be connected to the SLAC network using a modem and ARA software. After the connection is made, the Mac will appear as though it were connected to the SLAC network as the Mac in your office is, except that the communication will be at your modem's speed and therefore slower.

Send e-mail to ara-request@slac.stanford.edu for ARA accounts after you have purchased your ARA software. Indicate in the mail message that you wish ARA authorization and give your first and last name and your SLAC phone extension. The SCSC will call you about your new account.

QuickMail is an electronic mail system used on SLAC Macs to exchange mail with SLAC's Macs and other networked computers and terminals (e.g., VM, VAXes, most UNIX workstations, X-terminals, and PCs, and other computers on the Internet). For QuickMail authorization have your Apple Support Coordinator (ASC) send mail to qm-request@slac.stanford.edu with your first and last name and SLAC phone extension. The SCSC will call your about your account.

CHAPTER 4 Tape Media Services

What are Tape Media?

Tape reels and tape cartridges of various lengths are considered to be tape media. 3480 original-length, 3480 extra-long, and 3490 double-length tape cartridges are used in the Automated Cartridge System (ACS); 8mm data and cleaning cartridges are used in the compute farms; and the older generation 3420 tapes reels of various lengths can be read and written on the two remaining 3420 tape drives.

The following table indicates the specific characteristics of tape cartridges used at SLAC:

TABLE 3. Tape Cartridge Characteristics 
------------------------------------------------------
Tape Cartridge  Length (ft)  Number of   Capacity (MB)  
                             Tracks                     
------------------------------------------------------
3480-OL         574          18          210            
3480-XL         669          18          250            
3490            1100         36          1000           
8 mm data       367                      2.5-5 GB       
------------------------------------------------------

Slot Allocation

Slot allocation is required by groups for experiments needing cataloged cartridge activity in the ACS. Slot allocations are determined by experimental needs and set by the Computer Coordinating Group (CCG). We suggest that unused slot allocations be returned to the general pool and be made available for future experiments. To request or return slot allocations, send e-mail to servdesk@slac.stanford.edu. State experiment name, group, tape czar name, number of slots desired or returned, and prefix if applicable.

Cataloged, User-Cataloged, and Non-Cataloged Tape Media

Cataloged tape media are labeled and stored in the SCS tape library. When you need to read and/or write a cataloged tape, you request it by its label in your program and it will be automatically readied for access.

Non-cataloged tape media are given a numeric label. Because they are not stored in the SCS tape library, they must be removed from the ACS after being used. Non-cataloged tape media are useful for data that is used only once or infrequently. Both cataloged and non-cataloged cartridges require a bar-coded external label available at the SCSC desk.

Cataloged tape media are often part of a tape media collection for major projects or experiments and are labeled with a prefix in the series QA through QZ for cataloged 3490 media, RA through RZ for 3480 media, and SA through SZ for 3420 media. Miscellaneous user-cataloged tape media are labeled with the prefix QM and are typically used for a small tape media collections (10-50). Both cataloged and miscellaneous user-cataloged tape media are stored in the SCS tape library or in the ACS unlike non-cataloged tapes which are not controlled by SCS.

How Do I Purchase Tape Media?

Once each year SCS purchases a large quantity of tape media to cover user's anticipated needs for the coming year. Users can purchase tape media from SCS and have it charged back to their department. SCS has established a mechanism called a draw account using the automated Media Management System (MMAS) System that allows users to reserve a quantity of tapes for future use. Typically the draw account is used when a fairly large volume of tape media is needed, although it can also be used for smaller volumes. Send e-mail to servdesk@slac.stanford.edu to establish a draw account. In addition you will need to fill out a New Media Purchase Request (see Appendix A) indicating the particular type and amount of tape media you need initially.

After the initial purchase of cartridges for a draw account, the draw account is used through the MMAS System with Reserve Requests. When the initial purchase is exhausted, adding additional cartridges to the draw accounts requires filling out another New Media Purchase Request. SCS determines the prefix to be assigned to tape media in the draw account (see section "Cataloged, User-Cataloged, and Non-Cataloged Tape Media" on page 8). Note: For catalog prefix requiring external bar-coded labels, send online memo to servdesk@slac.stanford.edu. Give the experiment name, group, charge number, number required (in lots of 1,000 only), and prefix, if known.

You can purchase tape media without opening a draw account. Simply fill out a New Media Purchase Request.

  1. Complete the section User Information and in the section Media Selection check the kind of media you want.
  2. Sign the request. It does not need to be signed by your supervisor or group leader.
  3. A group account charge number is required to process the form.
  4. Return the form to the SCSC.

Initializing Tape Media

  1. First determine whether your tape media is cataloged or non-cataloged.
  2. If it's a non-cataloged user tape with a numeric label, use the Media Movement Request form.
  3. If it's a 3420 tape, fill out an SCS Tape Service Request form.
  4. Cataloged tapes (labels RA through RZ and QA through QZ) can be initialized through MMAS. (Enter the VM command HELP MMAS for more information.)
The default for initializing 3480 XL and 3490 DL cartridges is standard label with compression. Requests for cartridges without compression should be stated in MMAS on the comments line of the Initialize Cartridge Service Request.

Reading and Writing Tape Media

3420 tapes are used exclusively on VM 3420 tape drives. 3480 and 3490tape media are used exclusively in the ACS and are accessible through the VM, UNIX, and VMS systems. The UNIX compute farm uses 8 mm cartridges.

Give the VM command AID tape, the UNIX command man -k tape, or the VMS command help cartridge for online help. You can find useful pointers at the end of the help files that relates to the specific machine that you are currently using.

Offsite Tape Archival and Retrieval

Each month SCS sends copies of SCS's monthly dumps of VM minidisk and VMS backup as well as user-generated archived files as needed to offsite storage. Special requests for retrieval of offsite tapes can be made via the Offsite Tape Retrieval Request form found at the SCSC desk. A nominal fee is charged for this service depending on the urgency of retrieval.

Using the Media Management System (MMAS) System

Use MMAS to manage labeled cataloged tape cartridges in the Automated Cartridge System (ACS) and perform operations such as reserving staging, initializing, degaussing tape cartridges, entering and ejecting cartridges from the ACS, and generating reports. MMAS may be accessed from VM and may require privileges given within each group by the tape czar and the SCSC . To get more information enter the VM command help mmas. If you are a first-time user and wish personal instructions, contact the SCSC.

CHAPTER 5 Pocket Pager Services

SLAC has three kinds of pagers:

Currently no pager is available that will reach La Honda. However, special services can be arranged for coverage in Pacifica, Southern California, and outside of California.

Pager operating instructions will be supplied with new pagers. Directions for how to page and how to receive a page from someone on- and offsite are given in the SLAC Telephone Users' Guide(3).

Ordering, Returning, and Repairing Pocket Pagers

The SCS Computer Support Center handles pager orders, returns, and repairs. To order a new pocket pager, fill out a New Pager Request Form available from the SCSC (and soon also from WWW) and return it to the SCSC, M/S 97. The cost of the basic and special pager services is given on the form. Use the Pager Service Request Form when you wish to return your pager, obtain a loaner, or have your pager repaired. To request service on a pager, stop by the SCSC Desk during normal hours (see Table 1) or return pager and Pager Service Request Form with the appropriate information to the SCS Computer Support Center, M/S 97.

Given complete and accurate information, requests will usually be filled within two working days. The SCSC will notify you by phone or electronic mail when your pager is ready for pickup.

Loaner, Lost, and Stolen Pagers

Please report a lost or stolen rented pager to the SCSC. You will need to give the SCSC the number of an account to be billed for the cost of the lost or stolen pager (typically $125).

CHAPTER 6 Videoconferencing

SLAC has one dedicated video teleconference room in the Computer Building, Room 112 for conferencing with sites on the Energy Research Videoteleconferencing Network (ERVN). The National Energy Research Supercomputer Center (NERSC) at the Lawrence Livermore National Laboratory serves as the video teleconference hub of ERVN through which video teleconferences are connected. NERSC has also developed an automated video teleconferencing reservation and scheduling system, called VCSS, through which all sites must schedule their videoconferences.

SLAC's videoconferencing system uses the Federal Telecommunciations System (FTS 2000) dial-up digital telephone network for transmission and equipment from VTEL and Teleos. The dual monitor system allows point-to-point and multi-point conferences and is easy to operate with either a remote control or table top controller. Also provided in the center is a telephone, document camera, overhead projector, an Ann Arbor terminal and VoicePoint unit(4) (when requested). Connection to a another site is as easy as making a telephone call provided that the conference has been scheduled in advance through the SCS Computer Support Center (SCSC).

Scheduling a video conference can be tricky. Besides requiring consideration of time zone differences, sites that SLAC users conference with are busy at least 30 hours per week. So it is very important that you first coordinate your conference with offsite participants. After you have coordinated scheduling and room availability with the people from other site(s), schedule SLAC's conferencing system by calling the SCSC (see Table 1) or send e-mail to servdesk@slac.stanford.edu 24 hours before the conference is to be held.

Consult the writeup A User's Guide to Video Teleconferencing at SLAC(5) for a list of sites participating in ERVN, information that the SCSC needs to schedule a conference, and other helpful tips and hints.

Note: Conferences with non-ERVN sites may be possible. Contact the SCSC several days before you wish to hold the conference to find out whether it is possible because it often requires consultation with videoconference specialists at the other site and may also involve a test between SLAC, NERSC, and the other site.

CHAPTER 7 Print Services

Today most output at SLAC is printed on self-service, distributed, network-connected printers. These include various models of PostScript printers by vendors such as QMS, Talaris, Apple, NeXT, Hewlett Packard; non-PostScript Imagen printers; and several kinds of color printers. Central printing services provided by SCS to VM users include the 3800 high-speed printer for large text output, the Versatec printer/plotter for large graphics jobs, and the 3203 impact printer for mailing labels.

Finding a Printer

In the Computer Building Lobby, which is open 24-hours per day, you will find the self-service public printers and transparency maker listed in Table 3. The SCS Computer Support Center (SCSC)can give you assistance should you need it.

This printer is connected to AppleTalk zone CGB.
(b)
Can be used for paper and transparency output. When printing transparencies, call the SCSC before submitting the print job so that they can insert the transparencies into the input tray (otherwise, your output will likely be printed on paper). When you print 25 or more transparencies, please provide a charge number to replenish the supplies. Note that this printer is quite slow.
(c)
Ask at the SCS Computer Support Center desk for transparencies. Instructions for using the transparency maker are given above the device on the partition.

--------------------------------------------------------------------------------
If you have difficulty in determining the name of PostScript printers versus plain text printers among the printers listed in PRINTCAP NAMES, consult the VM file printer memo *.

3800, Versatec, and 3203 Print Services

Table 5 describes what to use each central printer for and the SCS dispatch service level. These printers are old and should be used only when distributed printers, such as the Imagen, are either not suitable or the print load on them would be unreasonable for their slower print speed. You can find more information on how to use the 3800 and Versatec in VM Notebook Module 27. Using SLAC's VM Printers(6).

(a)
Class A consists of blue-bar paper; some special print services are still available (e.g., blank paper, restricted print). For information call the SCSC. SCS will try to inform users through the VM logon message should the 3800 be down while VM is running.
(b)
Use the FORM attribute of the output file to select fan-fold (FORM STANDARD) or roll paper (FORM ROLL).

Printer Maintenance

SCS maintains and services the 3800, Versatec, and 3203 printers. The SCSC arranges for repair of Imagens after the Imagen key operator reports a problem. SCS also pays for the cost of and administers the annual maintenance contract for Imagens, Talaris, DEC, Textronics, and QMS. Currently, service and maintenance of all other printers, such as Apple, NeXT, and Hewlett Packard printers is the responsibility of users. We are establishing centralized maintenance support for these commodities.

CHAPTER 8 Other Scheduled VM Services

This section describes these scheduled VM services: spool file cleanup, minidisk backup, and reclaiming of SPACE-machine TEMPDISKs.

Spool File Cleanup

Each working day (Monday through Friday except holidays) at 11 pm, the SPCLEAN service machine dumps to tape and then purges "old" spool files. User files which are not dumped and purged are:

Minidisk Backup

Minidisks are backed up periodically during the month.

Twice a week dump

Every Monday and Thursday, usually between 1 am and 6 am, the BACKUP program copies all minidisks to tape except for three categories:

  1. Those whose files have not been updated by the user since the previous copy or dump.
  2. "Maxidisks" (minidisks of more than 260 cylinders).
  3. Group minidisks of over 50 cylinders that have not been explicitly put in the BACKUP list.
The tapes in this pool are rewritten monthly.

Monthly dump

Once a month, SCS dumps minidisks to a separate pool of tapes that are kept for longer periods. Here, all minidisks including those not updated since the previous BACKUP are dumped. Exceptions 2 and 3 above apply to the monthly dump. Monthly tapes are retained on a quarterly basis. Dump tapes written in January, April, July, and October are kept forever (offsite after age three years), while the rest are reused after aboutthree months.

For information on recovering your data from BACKUP tapes, enter the command: help recover

Reclaiming SPACE-Machine TEMPDISKs

Each weekday at 11 pm, "old" SPACE TEMPDISKs are reclaimed. For more details enter the command: space ? tempdisk, space ? temp, or space.

CHAPTER 9 Documentation

You will find a collection of reference documents on all SLAC-supported systems in the SCS Computer Support Center area. In addition, you can help yourself to selected documents pertaining to the UNIX, Macintosh, VMS, and VM systems as well as CERNLIB.

If you wish to share computer-related documents with others by providing copies to the Desk, the SCSC will try to find the necessary space.

Other places to look for documentation include:
