[louisji2008]

Hi,

Please give me help about below problem. Appreciate for your reply and advisor!

The 3PAR is a 7400 with 2 controllers, OS is 3.2.2 EMU4.

The front Module Fault LED of node cage is flashing, and cgcmd command reports Comms layer fault - redundant. The full output is:

SS7400_N2 cli% cgcmd -tc tty -C cage0 -c report_faults -p a

And I also see three lines errors in node 0 and 1  with shownodeenv:

    SBB Canister 1 CPU2       ---        ---        --- Unrecoverable   
  SBB Canister 1 memory       ---        ---        --- Unrecoverable

Hello louisji2008,

It seems you have a hardware issue mostly with Node 1.  Please check the 'shownodeenv' command output and I am sure you will find some values 'unrecoverable'.

I suggest contacting Support for rectifying this issue.
