I have a clustered 3070 and I'd like to move a LUN from filer2 (mostly SATA) to filer1 (mostly FC). I've already got the igroups/zoning etc (it's FC) set up, the question I have is on how to move the actual data. If I do an ndmpcopy of the LUN is there a way I can just add it with lun map? It seems like that's all I'd need to do but since I've not done it before any advice would be appreciated.
ndmpcopy + lun remap has worked for me.
Is there a step by step guide you could point me to for the process, or perhaps describe the steps in general terms? I thank you.
Something like this? {How I moved some volumes with a SQL servers LUNs in them}
Volume move Step 1...... lun show -v and make a note of all the disk serial numbers for the LUNs on the cluster. you will need them in step X
Power down both SQL nodes 
      - I would probably remove the original iGroup at this point. or simply  run >lun unmap on all the luns for that cluster.
Snap mirror the data one  last time 
Brake the mirrors and then delete the mirrors .....hmm well just  remove the relationships and SnapMirror snapshots.  
Rename **** and offline **** the old volumes 
Delete the cifs shares 
Rename the volumes on the new aggregate to the 'old' names 
Create the  cifs shares   
X.  lun offlline all the newly SnapMirrord LUNs (they  are prob offline anyway here because of duplicate lun names)
lun  serial on all the new luns.
>lun serial .....lunname.... old  serial lun online all the new  luns  
Then re-map all the new luns...... >lun map ...lun name... iGroup Name
Power on the active cluster node
Confirm all is working 
Power on the  passive cluster node

I have used snapmirror and vol copy in the past. Snapmirror worked best for me but you need a license for snapmirror first.
Hi.@ll.
it's not possible to fixed this task with "lun clone" and after them "lun split" ? On the same filer works fine that.
Or another option is , take lun offline and create new volume on destination and use robocopy about cifs share or anything.
Are this correct ways or do i have errors in reasonings ?
