PowerVault MD3200 issue with failed virtual disk

Update: As you can see, the disk group is a RAID10. So one drive failure should not lead to data loss.

Should I try a "revive diskgroup" ?

Hello Simon_Onea,

Can I get you to pull a support bundle so that we can review it to see what is going on?  I will send you a private message so that you can send me the log.  the revive disk group maybe needed but it is best to look at your support bundle first to ensure that will not cause any harm to your data.

Please let us know if you have any other questions.

Update2:

We crossed fingers and issued "revive diskgroup" from the command line and it helped! The disk group and virtual disk went online and became accessible to hosts.

Thanks for the reply Samuel!

I have sent you the support bundle in a private message.

We took the risk and issued the "revive diskgroup" and it helped!

We still don't know what caused the volume to go offline.

Hello Simion,

Thanks for the logs as it helps to look into your issue.  After looking at the logs you are running 8 year old firmware on your MD3200.  With running firmware this old there are a lot of issues that come up that have been addressed in newer firmware.  Your issue with the disk group and virtual disk going offline is one that was resolved in newer version of firmware.  Since your firmware is so old you will need to upgrade it in two steps. 

You will first need to go to firmware version 07.75.28.60.  Once you get to that version and all is stable then you can upgrade to 08.20.24.60.  Here are the links to the firmware as well as the instructions for doing a firmware upgrade.

Hello Samuel!

Thanks a lot for the updates and the instructions. Indeed the software of the storage was not updated since it was put in production.

We will try to perform the upgrade as soon as possible.

Is it true that we must solve the hardware issues first before attempting the software upgrade? (replacing the controller cache battery and replacing the failed drive)

 

Have a good day!

 

Best regards,

Simon.

Hello Simon,

It is best to have the system healthy prior to do the firmware upgrade.  I have seen some cases where the system was not healthy and when the customer did the firmware upgrade it caused loss of data, & other issues as well. 

Please let us know if you have any other questions.
