Steps to format a system disk
4-30
Formatting a system disk is used whenever the following system
changes occur:
When to use You can use the FORMAT command to format one or more of the
LPS system disks and to flag any new bad block areas. Disks are
formatted when:
•
A new system is generated from a SST.
•
An additional disk is factored into the system.
•
A system disk is replaced.
•
Read errors or other disk problems have occurred.
•
A new version of software is installed that has a new format
program.
•
A patch is installed which explicitly requires that the disk be
formatted.
Note: The FORMAT command deletes all files except the MBAIS
file, performs a sector check, and flags any new bad block areas. The
ERASE command saves the existing MBAIS and bad block files; no
new sector check is performed.
Caution: Contact your site representative before formatting
system disks
Caution: When you are installing a new system or a new version of
software, do not boot from disk. You must boot the sysgen processor
from the system software tape, so that you use the format program
contained in the new version of software.
The following steps are used to format a disk:
Step 1. Back up any user files residing on the disk to be formatted.
Step 2. Load the sysgen processor into main memory.
Step 3. Invoke the FORMAT command.
Step 4. Select the disks to be formatted.
Step 5. When the format procedure is complete, continue the full sysgen
process.
Refer to steps 1 through 11 of the full sysgen procedures for the
format procedures.
