I have encounter this solaris problem and it happens intermittent. When it happens, the system is freezing and unable to telnet/ssh in but the system ip is still able to ping. after that it will back to the normal and everything seems like be normal again. it is sun cluster setup.

scsi: [ID 107833 kern.warning] WARNING: /pci@0/pci@0/pci@2/scsi@0 (mpt0):

Disconnected command timeout for Target 0

[ID 646865 daemon.notice] Monitor probe time of 362.56 seconds is 1208.52 percent of Probe timeout.

The above erros looks to be related with SCSI device. Probe time below states, it was trying to check why it has happened, it failed with timeout.
what operations were you doing there?

the system up time: up 955 day

should rebooting can resolve the problem? :wall::wall::wall:

Before you reboot:

do you have backups? The disk may not remount. I would say, as a reasonable guess, that your disk is near death. Can you restore whatever was on the disk? Will you need to restore if it dies completely.

Reboot will solve the problem, probably not in the way you hope.
