HP StorageWorks Enterprise Virtual Array Updating Product Software Guide (XCS 09534000) (5697-0754, October 2010)

To power cycle the array, complete the following steps:
1. Complete an orderly shutdown of both controllers from HP Command View EVA. Then, power
down the array:
a. On the EVA4400, push and hold the enclosure power button on the rear of the controller
for a minimum of 15 seconds. The power button and the green LED start to blink when held
from 4 to 10 seconds.
b. On the EVA6400/8400, press and release the power button at the rear of the controller.
The power LED turns amber and the shut down process is complete.
c. To power down the shelf, you need to ensure the controllers have shut down and then remove
both power cables from all enclosures. Alternatively, you can power down the entire rack.
2. Power on the array:
a. Power on the circuit breakers on both EVA rack power distribution units. Verify that all disk
enclosures are operating properly. The status indicator and the power indicator should be
on (green).
b. Power on each controller (EVA6400/8400) or the controller enclosure (EVA4400).
c. Allow the array to start up completely.
d. Start HP Command View EVA and verify connection to the storage system. If the storage
system is not visible, click EVA Storage Network in the navigation pane, and then click
Discover in the Content pane to allow HP Command View EVA to discover the array.
Verify the status of each host before enabling access.
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:
• Server-based management is required to upgrade the disk drive firmware.
• 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.
• For EVA4400 and EVA6400/8400, you must be running XCS 09522000 or later to upgrade
disk drive firmware online. If you are running an XCS version earlier than 09522000, you must
upgrade disk drive firmware offline.
• Although it is not required that the disk drive firmware be upgraded when the controller software
is upgraded, it is strongly recommended that you perform these tasks together. The disk drive
firmware complements the operation of the controller software and, for best results, the two should
be used together.
