Setting LVM.enableResignature =1 remains set after a SRM Test Failover (2010051)
SRM does not check how snapshot volumes are presented to ESX/ESXi hosts, and so, SRM does not support setting the LVM.enableResignature flag set to 0. If SRM sets the flag from 1 to 0, a virtual machine outage might occur each time you perform a test failover or during an actual failover.
Setting the LVM.enableResignature flag on ESX/ESXi hosts is a host-wide operation. If this flag is set to 1, all snapshot LUNs that are visible to the ESX host and can be resignatured, are resignatured during the host rescan or upon the next host reboot.
If snapshot volumes unrelated to SRM are forcefully mounted to ESX/ESXi hosts on the recovery site, these LUNs are resignatured as part of a host rescan during a test failover or an actual failover process. As a result, all the virtual machines in these volumes become inaccessible.
