Need to change internal tape drive driver from atdd_leg to stape

[S.Rider]

The driver on our C5683A internal tape drive on one of our 11.31 vPars was changed to atdd_leg by accident via the atdd_claim command. I'd like to change it back to stape so Ignite2Tape can run. How can I change it back ?

hi,

would a simple rmsf work?

#rmsf -H hardware path of tape

then recreate with insf

#insf -H hardware path of tape

if not you may need to go though the SMH to do it

Andy,
I tried that but the device still shows with the "atdd_leg" driver even after the "rmsf" and the "insf" just re-creates the device files without changing the driver. 8-(

hi,

ok then have a look at this link.

http://ftp.wu-wien.ac.at/pub/adsm/devdrvr/HPUX/11i_PCI/README.DLKM

it does state that the force bindings will be lost after a reboot if you havent edited the file /sbin/init.d/atdd file.

and also

To configure all IBM Medium Changer devices on the system after the install
of ATDD package, run the command:
# /opt/atdd/bin/atdd_claim -c

To remove the claim with ACDD after the next reboot.
# /opt/atdd/bin/atdd_claim -u

have you tried a reboot? becasuse if you end up messing with the ioconfig of the kernal, you will need to reboot.

Maybe I mis-stated the problem, let me try again. The IBM library that this server is attached to for TSM backups looks and is running fine. Those tape drives are ALL showing with the atdd driver.
The problem is - my locally scsi-attached HP C5683A tape drive now has a atdd_leg driver. I want to "atdd_unclaim" the local drive.
This is a 11.31 vPar with atdd 6.0.0.78.
It's tough to get this server down for a reboot and since the only thing the tape drive is used for is a weekly Ignite2Tape, the customer would rather live with a couple month old Ignite tape, that give it up for the 2/3 hour reboot (it currently runs 47 oracle instances).
