PowerCLI

For upcoming testing there was a need to create 140 datastores on a cluster for testing. Who wants to do that much clicking and typing? Not me! You can use the below PowerCLI commands to get the SCSI ID’s, Create the Datastore and then Rescan all hosts in the cluster. How do i get the CanonicalName for allocated disks? Get-SCSILun -VMhost 192.168.1.103 -LunType Disk | Select CanonicalName,Capacity How do I create a VMFS datastore for the CanonicalName I identified above?

This is a great script to keep handy. If you have multiple RDM’s on a VM and need to get the NAA_ID for them the below PowerCLI command will get you that information. Get-VM VMNAME| Get-HardDisk -DiskType "RawPhysical","RawVirtual" | Select Parent,Name,DiskType,ScsiCanonicalName,DeviceName,CapacityGB | fl If you then need to match the SCSI virtual disk to the Guest OS this is a great article on how to do so.
