Alerts mentioned below may be seen on 7000 Series ZFS Storage Appliance working in a cluster configuration.

Issue reported on AK firmware version: 2011.1.x

SUNW-MSG-ID: AK-8001-RK, TYPE: alert, VER: 1, SEVERITY: Minor
EVENT-TIME: Thu Jan 31 15:42:59 2013
PLATFORM: i86pc, CSN: <serialno>, HOSTNAME: <hostname>
SOURCE: svc:/appliance/kit/akd:default, REV: 1.0
EVENT-ID: 665840e4-94f8-6516-eb1a-f90c0edd0c59
DESC: Communication with the cluster peer via a cluster interconnect link has been lost.
AUTO-RESPONSE: None.
IMPACT: Cluster reliability is impaired.  If the cluster peer is functioning normally but no cluster interconnects remain active, arbitrary and unwanted cluster takeover may occur.
REC-ACTION: Check the cluster interconnect cables and the state of the cluster peer.  Contact your vendor for support if an interconnect link remains inexplicably down.


But, no takeover or reboot or any other cluster interconnect related issues are seen.


Peer head seems to be working fine - without any issues.

 

PLEASE NOTE:  After upgrade to 2013.1.6.0, 'cluster link down' alerts are reported even on a 'normal' reboot.

See MOS Doc ID 2195659.1 (See also - Bug 23092294 clustron component fault shows up in problems while links are still active)
