Servers - DOS FDISK reports no fixed disks present with PCI RAID

Applicable to: World-Wide

Source: RETAIN tip H165018

Please read both of the following options before choosing the appropriate one:

Option 1:
If you have saved a copy of your RAID configuration prior to having this problem, use this file to restore your original configuration. This will erase your current array/logical drive configuration.

NOTE: Please note that if a hot spare (HSP) was defined and a drive went defunct (DDD), the hot spare would have replaced the defunct drive. When this happens the configuration that was originally saved to diskette will no longer be valid. In this case you should NOT restore your saved configuration file from diskette because it will corrupt your data. You should use option 2 if this has occurred or if you are uncertain.

- Boot the IBM SCSI-2 Fast/Wide PCI RAID Adapter Option Diskette version 2.02 and select option 2 "Start RAID Configuration Program (Array Config)".

- On the main menu select "Advanced Functions" and press <enter>.

- On the Advanced Functions Menu select "Restore configuration from diskette" and press <enter>.

- When prompted to enter the filename to restore the configuration from, type "name" (where name is your saved configuration filename) and press <enter>.

- Select "yes" and press <enter> when prompted to confirm. Utility will report "Successfully restored configuration. Press any key to return to menu" when it is done.

- Select "exit" and press <enter> until you are asked if you want to "Exit configuration Utility?".

- Select "yes" and press <enter> to confirm you want to exit and then press <ctrl><alt><del> to reboot.

FDISK should now work.

Option 2:
If you do not have a saved copy of your RAID configuration call the IBM HelpCenter to obtain the IBM PCI RAID FDISK diskette.

Using this diskette and the instructions given below will reconfigure your RAID adapter so that FDISK will work.

NOTE: You WILL lose your array/logical drive configuration and you will have to reconfigure you array. If you have an operating system or data on your drives, you should record your array/logical drive size and type (type would be RAID 5, RAID 1, or RAID 0) so that you can reconfigure your array. Call the IBM HelpCenter if you need help understanding how to record this information.

- Boot the IBM PCI RAID FDISK diskette and select option 2 "Start RAID Configuration Program (Array Config)".

- On the main menu select "Advance Functions" and press <enter>.

- On the Advanced Functions Menu select "Restore configuration from diskette" and press <enter>.

- When prompted to enter the filename to restore the configuration from, type "blank" and press <enter>.

- Select "yes" and press <enter> when prompted to confirm.

- Utility will report "Successfully restored configuration. Press any key to return to menu" when it is done.

- Select "exit" and press <enter> until you are asked if you want to "Exit configuration Utility?".

- Select "yes" and press <enter> to confirm you want to exit and then press <ctrl><alt><del> to reboot. When the server reboots you should see the following during POST:

IBM RAID Adapter BIOS Version x.xx - date

RAID Firmware Version x.xx
No log drives found: none installed

Press any key to continue

- Boot the IBM PCI RAID FDISK diskette and select option 2 "Start RAID Configuration Program (Array Config)".

- All of your disk drives should show up as RDY and you can configure your array normally.

FDISK should now see the fixed disks in DOS.
