Impossible to access on /vol1

hi team,
I'm a new with Solaris system and i'm a french, so my english will not be very good but I'll try to explain my problem.
I have a Sun server SunFire X4170 with Solaris 10 as OS.
since last week I am not able to access on /vol1 anymore. And bellow are the warning messages which are displaying during the starting of the server:

 WARNING: /pci@0,0/pci8086,340a@3/pci108e,286@0/disk@1,0 (sd2):

The disk c0t1d0 (kernel driver name sd2) is broken:
it has got an unreadable sector 167762.
Replace the disk!
The new disk must get identical (or similar) partitions, new filesystems, and data for /vol1 and /vol2 restored from last data backup.

please is there not another possibility to fix that or to repair this sector ?
because I'm sorry to tell you that, but we have not done any backup for this volume. Smilie
and I don't know if the disks are mounted in Raid5, so that I can just replace another disk.

please help

How many disks do you see physically in the server? Also post output of:
raidctl -S

You have a simple disk, c0t1d0, but I don't think that this necessarily means you have a failed device. The filesystem /vol2 is on the same disk c0t1d0s1, and that has mounted okay.

Can you run fsck on the command line? Something like this, I think:-
fsck /dev/rdsk/c0t1d0s0
