To list the volumes detected as snapshots, run this command:

# esxcli storage vmfs snapshot listOR# esxcfg-volume -l

To check whats mounted

#esxcli storage filesystem list

To mount a snapshot/replica LUN that is persistent across reboots, run this command:

# esxcli storage vmfs snapshot mount -l label# esxcli storage vmfs snapshot mount -l "VMFS_1"# esxcli storage vmfs snapshot mount -u "49d22e2e-996a0dea-b555-001f2960aed8"

OR

#esxcfg-volume -m 4fbfff40-d0358207-e61a-d067e5face92.

To mount a snapshot/replica LUN that is not persistent across reboots, run thiscommand

# esxcli storage vmfs snapshot mount -n -l "VMFS_1"# esxcli storage vmfs snapshot mount -n -u "49d22e2e-996a0dea-b555-001f2960aed8"

To resignature a snapshot/replica LUN (the volume is mounted immediately after the resignature), run this command:

echo 1 > /proc/vmware/config/LVM/EnableResignature

Brief Note

1. EnableResignature=0, DisallowSnapshotLUN=1 (default)

In this state, you cannot bring snapshots or replicas of VMFS volumes by the array into the ESX Server host regardless of whether or not the ESX Server has access to the original LUN. LUNs formatted with VMFS must have the same ID for eachESX Server host.

2. EnableResignature=1, (DisallowSnapshotLUN is not relevant)

In this state, you can safely bring snapshots or replicas of VMFS volumes into the same servers as the original and they are automatically resignatured.

3. EnableResignature=0, DisallowSnapshotLUN=0 (This is similar to ESX Server 2.xbehavior.)

In this state, the ESX Server assumes that it sees only one replica or snapshotof a given LUN and never tries to resignature. This is ideal in a DR scenario where you are bringing a replica of a LUN to a new cluster of ESX Servers, possibl
