Add Disk day-2 action fails on SDRS clusters with error Cannot invoke "Map.entrySet()" because "unitStatusMap" is null

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

• Day-2 Action ‘Add Disk’ doesn’t work correctly in vRA 8.18.1 on VM’s in a SDRS Cluster when the added disk on another SCSI Controller.
• The behaviour is as follows:

  • VM on SDRS with only SCSI-Controller-0	FAILED
    VM on SDRS with SCSI-Controller-0 and SCSI-Controller-1	OK
    VM on VSAN with only SCSI-Controller-0	OK
    VM on VSAN with SCSI-Controller-0 and SCSI-Controller-1	OK

• On a VM which uses SDRS and only has 1 SCSI controller available the 'Add Disk' action fails with:

  • ####-##-##T##:##:##.###Z WARN provisioning [host='#' thread='#' user='' org='' trace='' parent='' span=''] unknown.jul.logger.logWarning:### - Error while performing disk operation: Cannot invoke "java.util.Map.entrySet()" because "unitStatusMap" is null. for disk "http://#/#/resources/disks/#"

Environment

• Aria Automation 8.18.1 (Unpatched - 24282366 -  and Patch 1 - 24411566)
• vCenter Server 7.0.3x 

Cause

• The issue occurs if the:

  •  

    User has a VM provisioned on SDRS enabled storage cluster.

  • User wants to perform AddDisk and provide the SCSI controller explicitly.

  • The provided SCSI controller does not even exist on the VM in vCenter.

Resolution

• Fixed in upcoming 8.18.1 Patch 2
• Also fixed for VCF 9.0
