Troubleshooting and Recovery Operations When
Starting the System
2. In the Configuration File box, select Base (CONBASE) as the
configuration file.
3. Click Start system.
b. From the startup TACL prompt, issue this command for each of the
processors to be reloaded:
> RELOAD (nn), PRIME
c. From the Startup TACL window, configure a tape drive.
d. Restore a previously backed-up configuration file.
e. Load the system as described in The System Startup Dialog Box on
page 16-6 from the current configuration file (CONFIG). Check that the
CIIN file is enabled.
As a last resort, you might be able to perform a tape load from a system image tape
(SIT) to restore the system image files to the $SYSTEM disk (SYSnn and CSSnn
subvolumes) and then load that image into either processor 0 or 1.
When you consider performing a tape load from a SIT:
•
You must contact the GCSC for guidance in restoring your system disk from a SIT.
•
You can configure the Distributed Systems Management/Software Configuration
Manager (DSM/SCM) to create a SIT whenever a significant software update is
performed, or you can request one each time a new SYSnn is created. For more
information, see the DSM/SCM User’s Guide.
•
Keep a copy of the contents of your system disk on backup tape. Unlike an
alternate system disk, the system image tape that DSM/SCM can create does not
contain all the files that were on the $SYSTEM disk, including almost important
system configuration information.
•
Do not perform a tape load to bring up a new software release under normal
conditions. The normal procedure for bringing up a new software release is to use
the DSM/SCM to create a new configuration revision (including the system image)
and then to load the system from the new SYSnn subvolume. For more
information, see the Gnn.nn Software Installation and Upgrade Guide.
Caution. Performing a tape load from a system image tape (SIT) to restore the system image
files to the $SYSTEM disk (SYSnn and CSSnn subvolumes) is generally not recommended.
Perform a tape load only with the advice of the GCSC or your service provider. Loading
from a tape reinitializes the disk directory. In every case, the disk directory is overlaid with the
directory from the tape. All files that were on the disk are destroyed. The SIT does not contain
all the files that were on the $SYSTEM disk, including almost all important system
configuration information. Many additional steps are required to restore your system to working
order.
