Re: /dev/nrmt0h: No such device or address
I suspect the operating system has created new /dev/*rmt* 'device special files' for this new device.
(It should do this after a power up/ reboot of the server.) Unhelpfully it doesnt know that you removed the old one, so it leaves the old redundant device special files in place.
Try the command:
file /dev/nrmt*h
This should identify which device(s) have a SDT-9000 against them. (It may be slow to respond as it will query the attached tape drive(s).
Example output:
/dev/nrmt1h: character special (9/37891) SCSI #2 SDT-9000 tape #17 (SCSI ID #5) (SCSI LUN #0) 97000_bpi
Just look for the SDT-9000 in the above, that shows the tape drive is there.
If you just get:
/dev/nrmt1h: character special
Then the device special file is not attached to the tape drive.
So you could just use /dev/nrmt1h or whatever it happens to be attached to on your system according to the results from the above file command.
(Don't worry if you don't get anything, it just means the device special files have not been created yet. We can fix that.)
If it was replacing an existing device on /dev/nrmt0h and you need it to be on the same device file name, then remove the old entires (carefully, I list them first to make sure only the entries for device 0 are going to be removed):
ls /dev/*rmt0*
(Don't worry about the different letters displayed by the ls command before and after the rmt0, just make sure only rmt0 is shown in the middle.) Change the ls for rm:
rm /dev/*rmt0*
Then you need to use MAKEDEV to create entries for your new device:
cd /dev
./MAKEDEV tz6
(Where the 6 is 8 * Bus + Target: 8 * 0 + 6 = 6. So if you need to do another one, this is how you calculate the tz number.)
Since you have removed the '0' device entries MAKEDEV will pick the '0' number to re-create. If you don't remove, it just picks the next free number, but it will report what it has created.
Type the command:
file /dev/nrmt0h
This should now show the SDT-9000 attached.
A bit long winded, but I tried to explain briefly what is going on.
Hope this helps.
Howard.
