HP StoreVirtual & SRM – Case Of The Missing Datastores

Problem Statement

Datastores do not show under Array Managers > Devices and therefore you cannot create Protection Groups.

Replicated datastores have virtual machines within them and replication has completed within the Centralized Management Console

Methodology

• HP StoreVirtual SRA installed from HP StoreVirtual Storage
• SRM server has an interface on the iSCSI subnet
• .NET Framework 3.5.1 installed on SRM Server as without this you won’t be able to discover the Storage Replication Adapter

Solution

Even though your datastores are showing correctly and are replicating, a lower case character match is required between your vSphere iSCSI and the CMC initiator node name.

In my case the vSphere IQN contained DC01-ESXi01 in capitals, whereas the CMC IQN contained dc01-esxi01.

• If you change the IQN in vSphere to the same name but in lowercase characters, connectivity remains
• Perform a rescan of Storage Devices and VMFS Volumes
• Verify that datastores are now showing under Array Managers > Devices
• Create Protection Groups
