NOTE: After upgrade of the controllers, the array may not be visible from HP P6000 Command

View. Either wait at least 15 minutes for the array to reappear, or reboot the server if necessary.

Step 6. Upgrading disk drive firmware

Estimated time to complete: Varies depending on the number of disk drives that require upgrading

and the I/O load on the storage system. It can take 30 seconds to 3.5 minutes per drive to upgrade

the firmware.

Review the following guidelines and tips before proceeding with the upgrade:

• When using HP Command View EVA 9.2 or later, you can upgrade disks that contain Vraid0

virtual disk data by halting all I/O to Vraid0 virtual disks (other Vraid virtual disks can continue

to service host I/O). When using HP Command View EVA versions earlier than 9.2, you must

either delete the Vraid0 virtual disks or ungroup the disks individually before upgrading disk

drive firmware.

• Although it is not required that the disk drive firmware be upgraded at the same time as the

controller software, it is strongly recommended that you perform these tasks together. The disk

drive firmware complements the operation of the controller software and, for the best results,

the two should be used together.

• When upgrading many (more than about 20) disk drives online, a loop may fail; to reduce

the chance of such a loop failure, upgrade about 15 or 20 drives, then pause the activity for

several minutes by navigating away from the upgrade. Continue after a few minutes. To
