This could be be design but I want to verify others have also seen this:
Took replay from Dell Compellent, created volume, assigned it to host group \ VMware cluster
Once this was done each host could see the LUN in the devices section of the web client
However, when adding the LUN to first host in the cluster, I expected all hosts to automatically add it per normal operations, but this didn't happen, no matter how many times I re-scanned the other hosts, they never picked up the LUN. I had to manually go down the list of hosts and add the datastore 1 host at a time, very inconvenient as there are many hosts in the cluster. This is only 1 LUN, and in DR test we will have a dozen or more snapshot LUNs to add to the DR cluster.
In normal storage operations, you add a datastore and all the hosts in the cluster mount it automatically. Why isn't this now happening with the snapshot LUN?
- LUN is RW
- LUN is now a datastore for all hosts, but manually added, a real pain
- I kept the existing signature of the LUN when adding it
Can anyone shed light on this behavior?
