EVA5000

We are using HP EVA 5000 with one disk group. All the disk in that group are 300 GB with hp01 firmware. Now we want to add 6 more new disk to the same group but they are firmware hp02. Can anybody explain do we need to upgrade the exsiting disk firmware from hp01 to hp02 to make all in one firware? if so how we can do that.

Thanks

Hi Gopi,

It works fine with a different firmware but it is advisable to install the same version.

Ask at HP for the firmware and update procedure

Thanks for the reply but my doubt is that while upgrading the disks in the existing diskgroup we have to release each disk from the group and upgrade or we can do with in the diskgroup itself?

Hi

There are 2 ways of upgrading the disks firmware, the slow and the fast way :)

Slow : Ungroup one disk, wait for ungroup to end, upgrade firmware to that disk, and the group it again. Repeat to all disks. Takes more than a week....

Fast : Shut down hosts connected to EVA. Upgrade controllers firmware. Upgrade disks firmware (all at once). Boot systems. It will take more and less 2/3 hours...

Never used the slow method...and the fast one always worked for me....

Bye

The slow method described above is unviable because ungroupping the disk normally could take more than 6 hours.

You can run with mixed disk firmware.

Depend on each disk HP release different FW. more than one FW can exist on EVA.
FW has some functions:
1, help EVA detect Hardware
2, some what is performance
...

You mean we can have mixed FW in the same disk group

[Hank Eggers]

Yes you can have different drive firmware in the same disk group if the newer drives are from a different manufacturer.

Now if your existing disk is from the same manufacturer as the newer drives then you would want to upgrade the firmware from hp01 to hp02.

HP normally wants to do these firmware upgrades themselves, so if you've got any sort of support access, get in contact with your HP rep and schedule a visit. As pointed out in previous posts, the "fast" method of upgrading is really the only way to go, but it does require a short period of downtime.
