hi,  In Clariion, SP reboot should not result in Path dead (if PP is installed and host configuration is correct). Same is with VMAX upgrade, if host has redundant paths and multipathing is configured then there should not be any impact.   regards, Saurabh
IHAC planned code upgrade to 5875.267.201; though its non-disruptive; i have few queries  Question:In CLARiiON each SP's reboot and result path outage coming from that SP. We have similar path outage from VMAX ?  whether We need to ask server team to be alert? Any impact analysis documnet in powerlink available?  Thanks in advance. regardsPras
