VSC 6.2.1 with SnapCenter 2.0


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:


Is there a limitation with mounting a snapshot/backup containing more than one (1) LUN in a volume?






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.
