Failed Virtual Volume

[rbogle]

I am attempting to recover a virtual volume that the system has marked failed and preserved. For some reason the system has the repair option greyed out in the GUI There are snapshots which are also marked as failed / unavailable attached to the system.

Optimally checkvv via cli would correct the issue; however the vv is online, how do we set the vv to offline to run the repair?


examples below:

checkvv -n output

We will only do consistency check and will not repair anything.

i should mention this in InFOrm 2.3.1

[gkapoor]

There is a switch with checkvv command in CLI i.e. -offline.

You can use it like this.

checkvv -y -offline DATA_VirtualVolume

Check help for checkvv.

Thanks,

apparently that option is not present in 2.3.1

It is also missing from the CLI guide and help.
