You might want to exclude the gatekeepers (and other Symmetrix special LUNs) from monitoring if that is the case: how to do that depends on which monitoring program you're using.MK MK Since the SAN is active/passive only 2 paths can be used, the other two paths are in standby mode. Alternatively, a qualified version of PowerPath may be installed, which will automatically filter these errors. The access can be a read or write attempt, and may occur with commands such as "fdisk -l".
