How to determine why LUNs are continually trespassing?
There are several LUNs on our VNX array that continually trespass. These LUNs trespass every 10 minutes or so. Each LUN is configured as a RDM in vCenter and attached to the same server. (There are 7 RDMs attached to the server currently). This is what I am seeing:
Three LUNs will be trespassed. These three LUNs will be trespassed for around 10 minutes.
LUN 0, LUN 1, LUN 2
Then LUN 0-2 will no longer be trespassed, but a different set of three LUNs will trespass.
LUN 3, LUN 4, LUN 5
Again after around 10 minutes another set of LUNs will be trespassed
LUN 6, LUN 7, LUN 3, LUN 4, LUN 5
This process continually repeats - Not always in this order. These LUNs are configured for replication in RecoverPoint and are actively replicating. Is this the cause of the LUN trespassing, and is this behavior normal?

Are the hosts set to Failover mode 4 ? What is the path selection policy set to on the ESXi hosts ?

This is nearly certainly the result of misconfigured MPIO on the attached host(s).
But I responded in particular to mention that you have this posted in the Clariion community forum, and you would probably find that there are more eyes on the VNX community forum; if you are still having issues you may want to post there to get a wider audience.
These days the Clariion forum is most often used by people who have old CX arrays...many of which aren't even under a maintenance contract anymore.
