Creating a System Image Tape (SIT)

This subsection applies only if you are running SYSGENR outside of DSM/SCM, an

action that is not recommended. DSM/SCM has its own way of creating a SIT.

Using DSM/SCM (before SYSGENR is run), you can enter an ASSIGN

SYSGEN^TAPE command to specify the tape drive where BACKUP should write the

system image, for example:

ASSIGN SYSGEN^TAPE, $TAPE3

Alternately, you can capture the above and other BACKUP options in a single PARAM

SYSGEN^BACKUPPARAM command, for example:

PARAM SYSGEN^BACKUPPARAM "$TAPE1, NOUNLOAD, LISTALL"

For information on these ASSIGN and PARAM commands, see Section 3, Using

Preprocessing Commands.

SYSGENR completes any DISKGEN executions you have requested, then prompts

you to create a system image tape (SIT). SYSGENR asks if you want to create a SIT

by displaying the following prompt:

Enter “E” or “Exit” to close the CONFLIST file and terminate SYSGENR.

If you enter “B” or “BACKUP”, SYSGENR prompts you for BACKUP options:

SUPPLY THE TAPE NAME AND BACKUP OPTIONS:

{ tapedrivename [ , BACKUP-option ] ... [ ! ] }

To respond, use the syntax shown below.

$tape

is the tape drive where you want the SIT produced.

Caution. You should perform a SIT load only in an emergency and on the advice of a service

provider.

A SIT load is a destructive function that erases all files on the system disk, including all

information in the system configuration database. You should maintain a recent backup of the

system configuration database because this information is not stored on the SIT.

If you perform a SIT load without also restoring the system configuration database, you must

reconfigure all system processes and peripherals that are created using SCF. Many additional

steps are also required to restore the system to working order. Contact your service provider

for more information.

Enter ‘BACKUP’ to get the BACKUP prompt or ‘EXIT’ to exit SYSGEN
