Recovering Installed Products Using SIT2SCM
Recovering Installed Products Using SIT2SCM
If you are trying to recover from a disaster on a NonStop S-series system that has a
backup tape and on which the Operating System Image on $SYSTEM has been
damaged, you can boot from a SIT tape and use the SIT2SCM macro to install the
products that DSM/SCM requires from an RVU. SIT2SCM is located in the
$SYSTEM.SYSnn subvolume on your system.
To use SIT2SCM:

If you use a home terminal other than the $ZHOME process, you must pause that
home terminal for this procedure.

You must have Super-user ID (255,255) access to the system.
This procedure assumes:

DSM/SCM files are on $DSMSCM.

TMF audit trails are on the $AUDIT disk volume.

The system tape drive is $TAPE0.
You might need to modify some commands in this procedure to fit your system
configuration.

2. Select File>Start Terminal Emulator>For Startup TACL and Start Terminal
Emulator>For Event Streams.
3. On the Low-Level Link toolbar, click Processor Status.
4. Select a processor to start.
5. From the Processor Actions list, select SIT Load.
6. Click Perform Action.
7. In the Load SIT Using Processor-n dialog box:
Caution. You cannot use this procedure for Integrity NonStop systems.
One or both of these steps ensure you always have a backup of your system information:

Running your system with a mirror of $SYSTEM

Creating a backup disk image of $SYSTEM and storing it in a safe place so you can
physically install and boot the backup disk if needed
