recently this sunfire 280R (solaris 10) is having problme, it was able to boot up, then all suddent, it failed, and I can't even mount the first disk which contains root partition when I boot up from cdrom.

2 X 36G hard drive,

I scan first hard drive by "read", there is no bad block. The strange thing is that I can't issue "refresh" or "test", it keeps saying the disk is write protected. (I boot from cdrom as well to single user mode).

Partition:


Part Tag Flag Cylinders Size Blocks
0 root wm 1936 - 24619 31.25GB (22684/0/0) 65534076
1 swap wu 0 - 361 510.65MB (362/0/0) 1045818
2 backup wm 0 - 24619 33.92GB (24620/0/0) 71127180
3 unassigned wm 0 0 (0/0/0) 0
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 0 (0/0/0) 0
7 var wm 363 - 1935 2.17GB (1573/0/0) 4544397


Here is the result for fsck.

fsck ran successfully, but I still can't mount that root partition.

Sounds terminal

I'm not sure, but Can you try

fsck -y fsck /dev/rdsk/c1t0d0s0

option -y : yes for all question

I think it should fsck for raw device (rdsk).


Ratcha.
