Hello,   If this is the only occurrence I would not be concerned.   Are you running older EQL firmware?     Yes, the error was corrected.   If you see a Unrecoverable error, that's a sign of defective HW.   Regards,   Don 
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?
Recoverable memory error
