Performing a full sysgen
Use the information given below when performing a full sysgen.
When to use a full sysgen In the full sysgen procedure, all system disks are formatted and the
operating system software is installed on the system disks. A full
sysgen is normally performed in the following situations:
A new system is installed
A system disk is replaced
Read errors or other disk problems have occurred
When required for a specific system or patch.
Note: When performing an offline (tape) sysgen, make sure the
system is offline.
Backing up user files It is important to back up all user files.
Caution: If the disk being formatted contains user files, be sure to
back up those files before formatting because they will be deleted
from the disk.
