Re: error in mounting file system

It appears that one of the disks, /dev/dsk/c1t4d0, in  your VG is dead.  

 

If the /dev/vgarch/lvarch spans both disks in the VG,c1t4d0 and c1t5d0,  and was not mirrored, then the dead disk is the reason your LV is not mounting.

 

Do an 'lvdisplay -v /dev/vgarch/lvarch' and post the first 25 - 30 lines of the output.
