I have seen this before, and yes it is normal from what I have heard. The RLPs are part of a global pool on the array which means that any RLP lun can be used for any MV/A session. When the session needs to grab a lun for the snapshot it takes, the RLP lun can be any lun, which means it could be on either SP. I don't think the system has an alogithm that says to choose a lun on that SP before pulling one from the other. I also don't think there is any way to avoid this trespassing.  -Ryan
we've seen a lot of "Unit Shutdown for Trespass" in the SP event log, it logs a entry like in about every 5min, see attached screen print, the luns are part of RLP luns, is this a normal activity? I can understand sometimes a lun is trespassed… but every 5 minutes…? that doesn’t sound right. this is on a CX3 with MV/A. thanks   [IMAGE]
