I worked on move RDM LUNs of Microsoft Cluster virtual machine from one iGroup to another. To make sure the moving safe, we should record RDM LUN information before migration.
We had two VMs with almost 20 RDM LUNs, it’s pretty time consume to get the information manually, I used following script to retrieve information:
$RMDinfo = Get-HardDisk -VM virtual machine name -DiskType rawPhysical $RDMinfo | select Parent,Filename,CapacityGB,ScsiCanonicalName,Name
