Is there a limitation with mounting a snapshot/backup containing more than one (1) LUN in a volume?
I have a single volume with five (5) LUNs.
Each LUN is presented to an ESX host as a datastore.
Each datastore contains two (2) VMDKs (7TB each)
I have a VM with all 10 VMDKs added to its disk configuration.
It is a Windows 2012 server with all 10 disks spanned to create a single ~70TB volume.
OK - don't ask why it was setup this way... but it preceeds my employment...
I create/run a backup job to backup the VM - including all spanned entities
Backup runs without error and I am able to see the snapshot listed in the volume (user_data)
When I try to MOUNT the backup in VSC to recover files:
Mount operation clones the snapshot.
I am able to see the temp volume and the contained five (5) LUNs within
However, only "User_lun_5" is mapped.
Therefore only "User_lun_5" is listed in the VSC GUI as a datastore to mount to my ESX host
The result is that I do not have ALL VMDKs available to re-create the spanned volume/disk to complete my restore.
When this approach is used WITHOUT SnapCenter 2.0 integrated with VSC 6.2.1P1D1 the process works as designed. Which leads back to my question:
try this to see if helps
So the official word from NetApp is that ONE LUN PER VOLUME is the rule... therefore only ONE LUN will be visible for mounting.
My question continues to be: "How does VSC pick the particular LUN out of a choice of five (in my example)?"
Stick to Best Practice (1 LUN per volume) and this will not be an issue.
