dell equallogic volume offline

We have dell eqaullogic arrays in group.
One device had disk failure and the volumes went offline.

How can I bring the offline volume back?
Will it bring the volume online if i replace the disk?

Volumes should not have gone offline if the array was healthy beforehand.

What does the GUI show for drive status for all members? What is in the event logs for the group? They should say why they went offline. Do you or did you have hot spares?

Are they under support and have you contacted Dell? I have lost probably a dozen plus drives over the years and never had it cause an issue with my Equallogic arrays going down.

Replace the disk,not reboot etc

What is the raid level? If you lost 2 drives AND the volumes went offline that probably means that you lost more drives than what the array could sustain and keep your data available.

Did both drives fail at once? Were you using RAID5? RAID5 is the only configuration that I can think of where you would only have 1 hot spare. Dell recommends that you not use RAID 5 and they have removed that option from later versions of the GUI.

You need to replace all failed drives. After you replace the failed drives, see if the volumes can be brought back online.
