You are experiencing these issues:

Raw Device Maps (RDM) are being reported by Windows virtual machines as unknown and unallocated.

ESX hosts report full connectivity with all LUNs including the RDMs.

No command aborts (CMdAbrts) or Bus resets (BusRst) reported at the Host Bus Adapter (HBA) level.

esxcfg-mpath -l reports paths per LUN involving all front-end ports on the array.

Logical Volume Manager (LVM) reports that snapshots are disabled. Enabling snapshots still does not help.

Navisphere Manager reports that there are snapshots sessions of a source LUN in place but some of them are currently inactive. Those inactive sessions match the UUID of the missing RDMs (taken from /proc/vmware/scsi/vmhba1/X:Y)

Warning messages similar to these appear in /var/log/vmkernel and /var/log/vmkwarnings report:

Aug 1 03:12:53 vppesx1 vmkernel: 10:19:07:07.881 cpu3:1034) SCSI: 8043: vmhba1:0:6:0 status = 2/0 0x5 0x25 0x1
Aug 1 03:12:53 vppesx1 vmkernel: 10:19:07:07.881 cpu3:1034) SCSI: 8120: vmhba1:0:6:0 is a deactivated snapshot.
Aug 1 03:12:53 vppesx1 vmkernel: 10:19:07:07.881 cpu3:1034) WARNING: SCSI: 5637: status SCSI LUN is in snapshot state, rstatus 0xc0de00 for vmhba1:0:6. residual R 999, CR 80, ER 3

Solution

To reconnect missing RDMs with virtual machines:

In Navisphere Manager, activate inactive SnapView sessions. Wait until SnapView reports the sessions as Active

Remove the RDM from the virtual machines.

Rescan the ESX host.

Re-add the RDM to the virtual machines.

Power on the virtual machines

Rescan the disks from computer management view. The RDMs will come up as available and NFTS formatted with full data access.
