i could not even power down system by pressing the power button.

If you cannot power off by a stop-a or pressing the power off switch then remove the power cord and re-insert.

1. install the cd media of the Solaris O/S
2. Power on and when you see the banner appear--press
the stop-a keys. This will take the system down to the
ok prompt.

3. If you are at the ok prompt ---proceed as showned.

. ok boot cdrom -s
. after booting up run format and see if you see the
system disk(s).
. If the system disk is seen then fsck the partitions
on the system disk ( you can get the partition
slices from the format ran above).

If you cannot boot from cdrom and cannot get to the ok prompt then if using a Sun keyboard ,observe the keyboard LEDS for further info.

Please post for further info.

init s goto single user mode,then use fsck

On a reboot a fsck is done on the file systems listed in the /etc/vfstab.

Do you see any error(s) in the var/adm/messages file?
Is there any info in the messages file prior to the time when you first notice the system's problem?

Run iostat -En and look for any disk errors.
