Alletra – Disks don’t appear

Synopsis

  • A Windows Server host has been provisioned with network connectivity to the Alletra controller “data” IP addresses
  • HPE Storage Toolkit has been installed
  • HPE Connection Manager indicates connectivity has been established from the Windows Server to the Alletra controller
  • HPE Connection Manager does not show any available volumes
  • Microsoft Disk Management console also does not show any volumes

Troubleshooting

Verify the IQN of the Windows Host using PowerShell:

get-initiatorgroup

Verify an initiator exists on the Alletra array with this IQN:

initiatorgrp --info Win-iSCSI-TE

Verify the volume that is expected to be available for the Windows server to connect to has the iniator group configured:

vol --info SQLCluster-TE.0 

Check HPE Connection Manager for errors:

Resolution

As the “recent tasks” pane indicates, the NimbleDSM is not running. Reboot the server to load it.

Disk management now displays the LUN ready to consume:
