Recovery Operations for Failed Disk Drives
Guide. If you have an alternate system disk for emergency backup, you can minimize
unplanned outage minutes.
If an alternate system disk is not available and you are unable to load from the
CONFBASE file, 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. Perform a tape
load only with the advice of the Global Customer Support Center (GCSC) or your
service provider. A tape load reinitializes the disk directory. In every case, the disk
directory is overlaid with the directory from the tape and all files that were on the disk
are destroyed.
