disk00 failed - lost the software image!

[johng231]

Hello

We had disk00 failed on a WAE-674 WAAS appliance. The software image was completely gone and all of the paritions along with it. I was told if you lose disk00, the image gets wiped out. Is this correct? If so, can someone please explain why it's design to not stripe the software image across the RAID-5?

Thanks in advance,

John

Hi John,

That is not correct.

If you loose a disk, wether it is disk00 or disk25, RAID-5 should do it's job and you should keep all of the partitions intact as long as you don't have another disk failure at the same time.

We had some issue with the 73X1 and 674 raid controllers firmware so if I were you, I would check the version I'm running ("show disks tech" > Controller Version Information > Firmware) and would upgrade the firmware if you are not running

5.2-0 (17002)).

Thanks for the replay.

We are running version 5.2-0 (15418). Is it recommended to upgrade all 674s and 73x1s to 17002?

Can this be pushed out via the CM? Or you have to hit every singe box individually??

Thanks,

John

Hi John,

Since your version is affected by the following field notice, I would indeed highly advise to upgrade:

I believe the install needs to be done from the CLI so I'm afraid you'll have to connect to every box to perform it.

It mentions upgrading to version 15427, however; there is a more recent one out,17002. Is it recomended then to go to the latest one?

Hi John,

17002 so you get the fix for both the FN and for the issue where the WAE is loosing the partition table.
