Pass-Through Disks or Physical RDM LUNs Disappear with HPE Storage Toolkit in a VM Environment

Whether or not VSS snapshots are being used, installing the toolkit on a Hyper-V or VMware virtual machine (VM) may cause the pass-through disks or physical RDM LUNs to disappear.

As a workaround, you can enable VSS Requestor/Provider running in a Hyper-V or VMware VM environment to support snapshots of pass-through disks or physical RDM LUNs and prevent DSM from claiming the pass-through or physical RDM LUNs in an iSCSI environment.

For Hyper-V VMs, see Microsoft Knowledge Base article 3011079.

  1. Log in to the VM.
  2. Using the MPIO control panel applet (mpiocpl.exe), remove the "Nimble Server" Device ID string from the list of MPIO devices.


  3. Reboot the VM.
