Reclaiming space from ESX host in Clariion box

Thanks

You should have posted this discussion in https://community.emc.com/community/support/clariion?view=discussions .

If you dont need the data in the metaLuns, you can simply  remove them from storagegroup and delete the MetaLuns and thus free up the diskspace.

I'm afraid this part of forum is related to backup.  You will just have to ask your question then in CLARiiON/VNX forum instead of NetWorker one.

If you had backup, just restore it.  Otherwise, no way.

I don't think so this is related to Backup. "Recover" - i mean to say that reclaiming the storage space.

The metaLUN that you were using, do you want to remove the metaLUN or do you want to use the space on the metaLUN for some other purpose. Destroying the metaLUN would release that space on the array and add back into each raid group the space that the metaLUN Component LUNs used.

If you just want to take the metaLUN and give that to a different host, just move the metaLUN to the Storage Group of the new host.

Hi Glen ,

              If the MetaLun is directly assigned to another storage group  , will the  data  from the previous host still remain on the Lun ? Will the new storage group see the total capacity of the MetaLun or only the available space will be used ? or Will it simply overwrite the existing data .

if you simply remove MetaLUN (or any LUN for that matter) from one storage group and present it to another, data remains intact. If you are moving from one windows host to another, it will be able to read that data, view disk capacity etc. If you present LUN from a windows host to a Linux host, it will not know what to do with it (typically it does not unless you load utilities that can read NTFS). You will need to go into fdisk and delete that partition and create one that Linux understands (ext3/ext4)

Thank you dynamox . Im clear now .

Cheers
