I have an EqualLogic PS4000E and I received this in an email:
-----------------------------------------
WARNING event from storage array member1
subsystem: SP [secondary]
event: 19.3.1
time: Fri May 8 00:41:04 2015
Recoverable memory error on CM in slot 1
Initiator of the data request was (0x0): CPU0
Responder to the data request was (0x6): L2 Cache
Correctable L2 cache data ECC error.
-----------------------------------------
I looked at the array and event logs and there was just the one message. Should I consider it self corrected, or should I seek further help?
