HP Scalable File Share G3 MSA2000fc How To

c. If the replaced controller is at a higher firmware level than its partner controller:
i. Unmount all HP SFS clients and targets (MGT, MDT, and OSTs) on all HP SFS server
nodes to halt all host I/O to the storage system. For more information, see section
5.4 Stopping the File System in the HP Scalable File Share User Guide G3.2-0.
CAUTION: In dual-controller configurations such as HP SFS G3, attempting to
update controller modules at the same time by logging in to both controllers fails
and leaves one or both controllers in an uncertain state. The following steps upgrade
the controllers individually.
CAUTION: Do not cycle power or restart devices during a firmware update. If the
update is interrupted or if a power failure occurs, the module could become
inoperative. If this issue occurs, contact HP technical support. The module might have
to be returned to the factory for reprogramming.
ii. Because the replaced controller is at a higher firmware level, use this maintenance
window to upgrade the controller firmware on all other MSA controllers. Upgrade
to the same version as the replaced controller, or to the latest firmware available for
your MSA controller type (MSA2212fc or MSA2312fc).
iii. Use the SMU or CLI interface to upgrade the firmware on the all other MSA controllers,
as described in “Upgrading controller module firmware on controller modules attached
to HP SFS” (page 8).
iv. After all controllers are upgraded to the same firmware level, start all HP SFS servers
and file system components (MGT, MDT, and OSTSs). For more information, see
section 5.3 Starting the File System in the HP Scalable File Share User Guide G3.2-0.
