mirrorview/s and vsphere esxi 4.1

Hi all,

we are experiencing some problems with mirrorview/s and vsphere replicating vmfs luns.

We use two vnx5100 with the latest OE, vsphere 4.1 esxi. The initial procedure for setting up the primary and secondary lun worked like a sharm, we got the secondary lun synched and shown as consistent. Then we performed a fracture, presented the secondary lun to a host and after a rescan we were able to see the new lun under storage devices. At this time we followed the "add new storage" wizard but instead of showing an existing vmfs volume and ask for resignature we get the message that the disk is blank.

Any one has seen this before?

Thank in advance

Sergio
