THe "..resignaturing.. & .. snapshot LUN.." message, makes me think that there is a LUN # mismatch. To test this, go to the Configuration Tab in the Infrastructure Client, go to Advanced Settings, click on LVM, and change LVM.DisallowSnapshotLun from 1 to 0. If after changing to 0, you can see the LUN, then there's a definite mismatch in LUN number from when the LUN was first created to now. If possible, I would unpresent the LUN from both Hosts (through the SAN management interface) and re-present the LUN making sure to use the same LUN for both of the hosts. Mayur You are right! I changed LVM.DisallowSnapshotLun from 1 to 0 and I was able to see the second LUN. Could I change the value back? Will I lose it again? Could I leave everything as it is? How will it affect functionality? If I do unpresent-re-present operation how can I be sure that I am using the same LUN on both hosts? I used SSP on MSA 1000 for configuration. Thank you!
