Looks like your disk c2t4do is dying, Better to go for a disk replacement at the earliest,Disk replacement can me done through vxdiskadm using options 4 and 5, and this being fcal disk you need used luxadm to remove and insert disk..Detailed procedure will be available in net.

U can set off the failing flags in the disk using command vxedit set failing=off disk04 .But in this case it wont help u as there is bad blocks in disk..better to go for a replacement..
