Why don't you try Asycronius SnapMirror between filers? Once trasnfer is completed, in a planned maintanance window, do Snapmirror Update, Unmap the original LUN, Mapped the New LUN from the Other Filer and continue on your normal business work

Re: MIGRATING LUN IN AN A-A CLUSTERED FILERS

agreed...best way to go. Also run "lun serial" to get the lun serial number to apply to the new location so the serial number is the same.  Depending on the OS there can be some troubleshooting when the lun has a different serial number so when we snapmirror luns for a migration we make sure the target has the same lunid and serial number and the host just works when it remounts.

Oops don have SnapMirror License is there any other way to do this please help me out .

Re: MIGRATING LUN IN AN A-A CLUSTERED FILERS

You can do vol copy - same end result, but no luxury of incremental updates.

Re: MIGRATING LUN IN AN A-A CLUSTERED FILERS

you mean to say copy theVolume on which the LUN residing right i mean

vol copy -S filer1:/vol/vol1/Lun1  filer2:/vol/vol1/Lun2

Will this command do ???      else what if i want to migrate only the Data from the LUN  in filer1 to filer2 LUN

Re: MIGRATING LUN IN AN A-A CLUSTERED FILERS

Yes… with the lun disconnected from the host though. A one time copy. You can also request a snapmirror demo key from your NetApp team and tell them what you are doing.

Re: MIGRATING LUN IN AN A-A CLUSTERED FILERS

You don't specify LUN path, just the volume.

If you want to migrate data only, you need to create target LUN first and then move the data via host, when both LUNs are connected.

Re: MIGRATING LUN IN AN A-A CLUSTERED FILERS

..... We are getting downtime from the  client so there will be no data written to that LUN at that TIME till this activity gets completed, Could you please tell me the detailed plan to do this.
