H165018:  DOS FDISK REPORTS NO FIXED DISKS PRESENT WITH PCI RAID

 TEXT:

 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.
