There is one of two things wrong here. The disk is dead or you have the
wrong device file. First you have see if you can see your disk. You will
need to know the hardware path by tracing down the slot and scsi ID.

ioscan -fnkCdisk

This will show you the disks on your machine. It will show all the device
files for each disk under the listing of the ioscan output. You will need
to see if you disk is claimed in the ioscan output and you will know it by
either the hardware path or the device file as you have listed above.

If the device file doesnt show up under one of the disks then you have
totrack down the disk with the hardware path. If the disk shows up and
there are no device files under it, you will need to do an insf -e to make
new device files. If the disk shows up with no_hdw then it is disconnected
or dead. If it shows up and the device file is there you should remove the
device file and do an insf -e to make a new one. If after that the disk is
there and claimed and the device file has been recreated then there is a
problem with the disk.

If the disk is unclaimed then you need to find a driver for it since the
stock drivers cant recognize it.

Hope this helps.
