2. Under the Advanced Settings GUI, choose LVM on the left menu window.
• LVM.EnableResignature—Make sure this is set to 0.
• LVM.DisallowSnapshotLun—Make sure this is set to 0.
These settings allow other ESX servers to see snapshots as normal DATASTOREs instead of a new
raw LUN. If exposing the snapshot back to the same ESX server is needed, make sure the
LVM.DisallowSnapshotLun is set to 1.
Repeat these steps for each ESX server in the environment.
3. Using the VMware VI client GUI, choose the ESX server, select the Configuration tab and then
choose the Storage Adapter link.
