Flag 14: Library Place Retry (W)
This flag is set when a high retry count
threshold is passed during an operation to place a cartridge back into a slot
before the operation succeeds. This flag is internally cleared when another place
operation is attempted.
Flag 15: Library Load Retry (W)
This flag is set when a high retry count
threshold is passed during an operation to load a cartridge into a drive before
the operation succeeds. This flag is internally cleared when another load
operation is attempted. Note that if the load operation fails because of a media
or drive problem, the drive sets the applicable tape alert flags.
Flag 16: Library Door (C)
This flag is set when media move operations cannot
be performed because a door is open. This flag is internally cleared when the
door is closed.
Flag 23: Library Scan Retry (W)
This flag is set when a high retry count
threshold is passed during an operation to scan the bar code on a cartridge
before the operation succeeds. This flag is internally cleared when another bar
code scanning operation is attempted.
Recovering from a BIOS update failure
Use this information to recover from a BIOS update failure in the blade server.
The blade server has an advanced recovery feature that will automatically switch
to a backup BIOS page if the BIOS code in the blade server has become damaged,
such as from a power failure during an update. The flash memory of the blade
server consists of a primary page and a backup page. If the BIOS code in the
primary page is damaged, the baseboard management controller will detect the
error and automatically switch to the backup page to start the blade server. If this
happens, a POST message
Booted from backup POST/BIOS image
is displayed. The
backup page version might not be the same as the primary page version.
You can then recover or restore the original primary page BIOS by using a BIOS
flash diskette.
To recover the BIOS code and restore the blade server operation to the primary
page, complete the following steps:
Note:
Changes are made periodically to the IBM Web site. The actual procedure
