We have a VM (vmware) with 2 RDM LUN's placed on old storage (CDOT)).
I have to move those RDM LUNs to new storage (also CDOT) with snapmirror.
Is this procedure OK?
1. shutdown VM
2. remove RDM disks on VM
3. dettach RDM LUN's on vmware
4. LUN unmap on old storage
5. snapmirror update
6. snapmirror break
7. LUN map back to vmware on new storage (do i have to use the same LUN ID?)
8. add RDM disks to VM
9. VM power on
Is this procedure OK or there is any other way? What about LUN ID's?
I m not sure, but just to check you need to validate the LUN serial Number
It's MUST be the same on SRV and DST NEtApp
lun show -vserver vs1 -path /vol/vol1/lun1 -instance
and moidfy it if necesarry
This looks like a good plan to me for moving it over to a new cluster. I am guessing you are using volume snapmirror for these?
Below are the steps for bringing up data access in a SAN environment after breaking a snapmirror. I am sure there will be some disk rescanning from the VMware side to get this going also.
