Answers to EVA4400 and WOCP questions
Iâve looked at the origin of all the search actions that came to my blog site. I can give following answers to most questions:
The firmware upgrade from a Pre 09520000 firmware is an OFFLINE upgrade. This means you have to SHUTDOWN the EVA after the firmware upgrade has been done.
Start with informing the users you will do the upgrade and you have AT LEAST 4 hours time.
Second make sure no other I/O will be generated by users, hosts, backup etc.
Start with the upgrade to CVE 9.1 (or above). This will alter some indexes on the metadata in the EVA. After upgrading to CVE 9.1 (or above), the EVA can not be managed again with CVE 8.x or lower.
Now make sure you have an SSSU âcapture configurationâ of you EVA. Some upgrades mess up the Vdisk naming.
Now start the firmware upgrade. First check your EVA is in good condition. So no warning signs, strange log issues and it is checked for itâs full redundancy.
Start the firmware upgrade. It will also upgrade the firmware of ALL the I/O modules inside the EVA. When you âthinkâ the upgrade is complete. Take a BIG cup of coffee, and take a walk around the building. This just to make sure you take the time for the firmware to land inside the I/O modules. When the upgrade is complete, all I/O modules should give you firmeware version 0085. Some will not give you a good serial number read-out. So now we do the shutdown.
If all is shutdown propperly, start the enclosures and wait for all drives to spin-up. Now start the controller enclosure and head back to your management server. Wait for the EVA to come online and check again the I/O modules and the Vdisk names. If all OK, proceed. If not. CALL HP (or your nearby HP partner).
Now upgrade the WOCP to firmware (If you do not have management server, this would be your first step. (no reboot needed))
Now upgrade the firmware of all the harddisks.
If all goes well you have a very stable working EVA4400.
