Error description
Instant restore operation fails for FlashCopy Manager for VMWare 4.1.1 with DS8000 if LVM.enableResignature setting is set to 1 on the ESX host. That is very likely in VMWare environments where Site Recovery Manager (SRM) is present. SRM automatically sets this option to 1 during a test failover or an actual failover. After the SRM operation the flag remains enabled and will not be reset. Only data stores located on DS8000 storage systems are affected. Because this is the only storage type that requires a forced mount during backup operation. Root cause is that the URL of the datastore changes during the backup operation in this environment. During instant restore the original datastore can no longer be identified using its original URL.
Local fix
Disable resignature temporarily: 1. SSH to your ESX host 2. execute: esxcfg-advcfg -g /LVM/EnableResignature to query the setting of LVM.enableResignature 3. if it's set to 1 execute: esxcfg-advcfg -s 1 /LVM/EnableResignature 4. rerun the instant restore opration in FlasCopy Manager
