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.
