Hello, because the way the handling of Snapshot LUNs has changed dramatically in ESX/ESXi 4.x we are looking in a way to set the LVM/EnableResignature parameter to 1 on our hosts through a script. We have done this on earlier versions of ESX but now we can no longer call this setting because of the change in ESX 4.x.
I am not going to explain why we want to do this because it would take to much time. But I would appreciate if someone had a sollution to do this, because now I go to the first host in the cluster and manually set the LVM/EnableResignature = 1 through the serviceconsole with esxcfg-advcfg -s 1 /LVM/EnableResignature, then the script filters the hosts and selects the first one by name and does a resignature on the datastores.
Can someone help me with this if it is possible. We are do not want to call putty from our script to do this.
BR
Henrik
