How I can mount vdisk Storage2?

Solution

Re: Unable to mount LUN. A virtual disk is down

# show snapshots master-volume Storage2

Try to delete snapshot if shows any from above output.

You can take help of command,

# delete snapshot force <Snap_name>

Once all snapshot cleared for Volume named Storage2 then try the below option,

# convert master-to-std Storage2

You need to keep in mind that you can't mount Vdisk rather you need to present Volumes to host.

 

Hope this helps!
