I am looking for an answer, basically we have 4 PS6000's running, and migrated from 1 to another one over the weekend all of our VMFS volumes. When i was done i marked the volumes offline in the Array Manager. Today I realized we had some unused vm's sitting there that we wanted for reference so when I remounted and re-attached to vsphere Im being told both volumes are un-formatted.
Ultimately this is not a huge problem but something i need to let our team know in the future if they mark a volume as 'offline' running vmfs and re-mount it , maybe it will come back unformatted ...
Thanks to anyone who can verify this ...
