No, no, no. You don't run fsck on slice2 (??????s2) of any disk because that defines the whole disk to Solaris and does NOT hold a filesystem.
You cannot currently mount c1t0d0s0 and c1t0d0s0. Take a look again at the vtoc for that disk (see my earlier post as to how to do that) and see whether either or both are filesystems. Quite often ??????s1 is defined as swap space. If both are indeed filesystems then fsck those slices:
Note that I have included the '-n' switch to check the filesystems without correcting anything first just to see how much damage, if any, there is. Don't use the '-y' switch at the outset because telling it to correct all errors might destroy the filesystem on the ground if damage is extensive. If errors are few simply run again without the '-n' and say 'y' to each question to correct the error(s).
On a production system I would expect there to be entries in /etc/vfstab to mount these filesystems at boot time?
Ah, you've got volume management in use looking at your vfstab.
Therefore, you should 'fsck' the raw (rdsk) devices in the 'device to fsck' column of vfstab eg,
on any filesystem that refuses to mount because it's flagged as 'dirty'.
Again, use the '-n' switch to examine how much damage there really is. If there are millions of errors then be careful. If errors are few then run again without the '-n' and answer 'y' to each question.
You can run 'fsck' on any/all of the devices in your vfstab 'device to fsck' column.
In above output i am able to mount all the devices and i was getting Needs Maintenance on : d3,d3,d3
When i had a look at metastat output one of the submirror of d3 i.e d13 (c1t0d0s4) is showing as maintenance and rest of the slices c1t0d0 are ok.
I tried to look for C1 controller and failed to get the information about it as i couldnt find the controller in devfsadm or cfgadm or luxadm as said in intial post.
Currently i have detached all the submirrors of c1t0d0 disk from all mirrors and tried to mount and able to mount them after running fsck on the s0 and s1.
But the maintenence slice c1t0d0s4 i am able to mout but getting error when i do the fsck.
Now not sure if we need to replace the disk if so how do we do that when we cant see the controller.
Note: these are legacy systems.
Thanks,
P

When you use volume management (meta) the meta database lives on a (usually) very small configured slice. That is where the OS keeps the information as to what is mirrored to what, what volumes are spanned across multiple spindles and the like. That slice is not a filesystem and is not mounted in the usual way (and is therefore not in vfstab).
So again, what do you mean by maintenance slice? Could it be the meta database slice (very small)?
