Solaris

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.

/pci@0/pci@0/pci@2/scsi@0/sd@0,0

what i found this is a local drive. there is no any amber light or hardware errors.

please check the

Code:

luxadm probe -p

and check /var/adm/messages, for the date, when this error has occurred.

Did this happen during a specific operation ?

luxadm probe -p
No Network Array enclosures found in /dev/es

for this incident happened intermittent. for those clients are connected to this system with ftp connection also freeze but the network was still up.

the system up time: up 955 day

should rebooting can resolve the problem?

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.
