M9K booting and performance issue

 Hi,

We are facing booting and performance issue in one of the domain in M9K.

Actually this domain is in cluster (Sun Cluster). 

For booting up, this domain takes more than 4 hours. Also we are getting the following messages continuously in the console,

WARNING: /pci@17,700000/pci@0/pci@1/pci@0/pci@1/LSILogic,sas@0 (mpt2):

        Disconnected command timeout for Target 13

WARNING: /pci@16,600000/LSILogic,sas@0 (mpt1):

        Disconnected command timeout for Target 50

WARNING: /pci@16,600000/LSILogic,sas@0 (mpt1):

        Disconnected command timeout for Target 50

'cfgadm -al' is itself taking more than 2 hours to produce the output.

Also Resource Groups in node1 are not able to switch to this node.
