and the device name it is creating the vg, but when i issue command
#vgextend /dev/vg00 /c2t1d0 am getting error
vgextend: Couldn't open physical volume "/dev/dsk/c2t1d0":
I/O error

Even " mediainit " reporting error

If you still face an issue, provide the output of
*) ioscan -funC disk
*) mediainit -v
*) diskinfo
