3.4.9.1 Low-Level Format Program
On non-disk array models, you have the option of formatting your hard disk
during the advanced diagnostic testing. The advanced diagnostic format program
is a low-level format program. It will completely reformat the disk which
includes removing the system partition.
Depending on the hard disk capacity, the low-level format program could take up
to two hours.
Use the low-level format program in the following cases:
•
When you are installing software that requires a low-level format
•
When you get reoccurring messages from the diagnostic test directing you to
run the low-level format program on the hard disk
•
As a last resort before replacing a failing hard disk drive
•
If you want to erase the system partition
Note
For non-disk array models, you must run the low-level format program from
the diskette.
For disk-array models, you must use the programs provided on the RAID
utility diskette to format the hard disk drives.
3.5 RAID Controller Utility
On RAID models, this utility is the only one that can discover and configure the
attached SCSI devices.
This utility comes on a bootable diskette which is shipped with every RAID
Server. Also, it can be rebuilt if necessary with the Diskette Factory option of
ServerGuide.
The IBM RAID utility allows you to configure disk arrays as well as view the
status of the arrays already defined. It provides a graphical display of the
defined arrays and provides diagnostic information to assist you if a hard disk
within the array malfunctions.
