Nimble storage and Windows Server 2012

[newbiehenry]

Hello,

So I have Nimble storage connected to FailOver Cluster in Windows 2012 R2 with 3 host servers. There was an issue this morning and the cluster was unstable. I evicted one of the Host servers and have the cluster running on 2 hosts. Issue I'm having is we have 4 volumes on the Nimble and currently Windows sees the mapping info for only 3  out of the 4. Looking at Windows Disk Manager and same 3 out of 4 have Volume labels on them. Checked iScsi Initiator and it's connected and it sees it just can't get the volume info to populate. Tried disconnecting it in iScsi Initiator but it didn't work since it said the connection was in use. Because it doesn't have the volume label it's not mapped anywhere and I have a vm file sitting on that volume. Any other suggestions or help would be appreciated.

Hi,
Without more details, it would be tough to troubleshoot here, but let me try

1. Are the Windows servers running on VMs or on a physical server?
2. Do you have HPE storage connection manager installed on the hosts? 
3. If you check the array UI, and select the volume, ACL, and sessions, does it show all 3 initiators?
4. Does the LUN ID order the same for all the cluster nodes? This can be verified from ACL settings on the array.
