Hi All,
After a little help with some PowerCli code here please. Im working on a project where i need to XvMotion <100 Physical Mode RDM VM's to a new vCenter + SAN environment. I have all the luns already documented and mapped out for every VM already, and i have written a script to automate the removal of the rawPhysical RDM LUNS from VM's in a CSV. However im now looking to recreate the RDM configuration on the VM's once they are migrated over.
I know the first node of the cluster gets the NAA.123456 lun mapped as a RDM, and the second node of the cluster maps the VMDK file in the datastore instead of the NAA.123456, however i was wondering if anyone has written a script to do this? The RDM's need to be added to a specific SCSI controller with specific SCSI ID's, which i was planning on putting in a CSV file with the NAA for each lun.
Ive been playing with New-Harddisk cmdlet, however i cant seem to get it to add the RDM lun on the first node during testing.
I was assumuing from a flow point of view, the script would work like this:
1: New-Harddisk adding luns to primary node
2: Use "Get-VM VMGuestName |Get-HardDisk -DiskType rawPhysical" to get the vmdk location of the RDM disks
3: Use Step 2 output to add VMDK's to secondary node.
Just wondering if anyone has gone about this before, and if there is an easier way than what ive mentioned above?
Thanks
Ryan
