IBM SAN768B-2, Installation, Service And User Manual

Page: 104 / 186

Attention: If the new CP blade does not have the same firmware as the active CP
blade, the new blade must be upgraded to the same firmware version. You can
determine the firmware version on the replacement blade and do a firmware
upgrade if necessary after inserting the blade in the chassis, but you MUST disable
high availability (HA) before inserting the new blade. If the new CP blade is
severely down-level, a very specific and detailed procedure must be followed to
bring the blade up to the correct firmware version. Refer to the
Fabric OS
Administrator’s Guide for information. Also see “Downloading firmware from an
FTP server” on page 79, “Downloading firmware from a USB drive” on page 81,
and “Fabric OS firmware updates” on page 43.

to Table 13 on page 79, to see which intermediate versions of the Fabric OS you
will need. Plan carefully and provide for extra time if this is your situation.
