I seem to be running into a problem with LUN ID's changing each time I alternate refresh/rescan my esx servers. Currently I have a cluster consisting of 2 ESX 3.5x connected to a NetApp 270 (using iSCSI). My goal is to use the FlexClone technology of the NetApp to take a snap of a VM's LUN (not running), clone it as a new volume/lun, have it available to the ESX servers, and Register the cloned VM. It works all well and good if I refresh/rescan the storage on just one of the ESX servers. The issue is when I rescan/refresh the second, it has a new LUN Identifier, and first ESX server cannot access the LUN it found, so I refresh again, and I get a third LUN ID. How can I get it so that both ESX servers see the LUN as the same ID? The ID is in the format snap-XXXXXXXX-<name> and its the XXXXXXXX part that changes.
