If the BIOS becomes corrupted (for example, from a power failure during a flash update), you can recover the BIOS using the recovery boot block and a BIOS flash diskette.
Note: | You can download a BIOS flash diskette from www.ibm.com/storage/support/nas. |
The flash memory of the IBM IP Storage contains a protected area that cannot be overwritten. The recovery boot block is a section of code in this protected area that enables the appliance to start up and to read a flash diskette. The flash utility recovers the system BIOS from the BIOS recovery files on the diskette.
To recover the BIOS:
The Recovery Boot panel appears. A progress report, Loading data from diskette xx%, is displayed. When programming is underway, a further progress report, Programming block n of 7yy%, is displayed. When recovery is complete, the following message is displayed:
Recovery complete, remove the diskette and return boot block switch to the off position before rebooting.
