VMware ESXI 7 and Intel NVMe SSD – Can’t add datastore
After a clean installation of VMware ESXi 7.0, I saw an NVMe disk (Intel DC P4600 4TB) in the system, but the datastore could not be added.
I solved the problem quickly as follows:
1. List unresolved snapshots or replica volumes.
# esxcli storage vmfs snapshot list
621cdcb9-053ddbab-e0a7-ac162d6f2e80
Volume Name: NVME-Intel
VMFS UUID: 621cdcb9-053ddbab-e0a7-ac162d6f2e80
Can mount: true
Reason for un-mountability:
Can resignature: true
Reason for non-resignaturability:
Unresolved Extent Count: 1
2. Resignature snapshot
# esxcli storage vmfs snapshot resignature --volume-label=NVME-Intel
Now it’s possible to add a datastore in the standard way…
Also don’t forget to install the Intel® Memory and Storage Tool CLI.
