Check and see if there's already a CD in the drive. I recall a recent thread where the author had to remove the CD that was already in the drive before it would unmount.

Hi Castro,

Make sure you (or anybody) is not sitting in the /cdrom dir.
User fuser -u /cdrom to verify.
You can't be there at mount time.

Make sure you are not in the mount directory, /cdrom, when attempting to mount the drive.

Hi
If you had used the "pfs" daemons earlier to mount cdrom,you will have to kill those pfs daemons first.

Thanks.

Yes there is a CD in the drive.

# fuser -u /cdrom
/cdrom:

# mount /dev/dsk/c2t1d0 /cdrom
/dev/dsk/c2t1d0: Device busy

Thanks

In the past we have had to power the DVD off and on again to get it to respond to the mount command.

Does bdf show /cdrom still mounted?
If so you'll have to unmount it first & then remove the drive.

If not currently mounted do
ps -ef | grep pfs
If pfs processes running you'll have to stop them - possibly even kill - to free up the device.

Rgds,
Jeff

Try ejecting the cd then replacing back into the drive

Since it is showing NO_HW in the Ioscan, Check all the cables including Terminator and the power connection. Then power cycle the DVD ROM, if it is external. Then check it in ioscan. Or DVD drive is deffective.
