Re: ioscan -fnC tape
Try to remove the device files for the tapes (rmsf) and install them again.
Hope this helps!
Regards
Torsten.

Re: ioscan -fnC tape
i presume that before you had other tape drives configured on this server...since it it is trying to attach one of the new tape drives to tape0. could it be that when you removed the previous tape drive the device files were not removed properly.
i would try to remove the device files for tape0 as explained above:
# rmsf -H
and then check whether there are still any files under /dev/rmt corresponding to a previous 0m* tape drive. if yes, i would delete them and try to recreate the new device files with:
# insf -H
i hope this helps.

Solution# mv /dev/rmt/* /tmp/tape
# insf -e
# ioscan -fnC tape
Please let me know the output
Dont worry about the device files(mv command), since the backup exist in /tmp/tape

Re: ioscan -fnC tape
You need to create the devices for the below device files
/dev/rmt/c18t0d0BEST
/dev/rmt/c18t0d0BESTn
/dev/rmt/c18t0d0BESTb
/dev/rmt/c18t0d0BESTnb
eg:
# ls -l /dev/rmt/c18t0d0BEST
Check the minor and the major number
eg:
# ls -l
crw-rw-rw- 2 bin bin 205 0x094080 Jan 12 1998 /dev/rmt/c18t0d0BEST
You can create the device file via
# mknod /dev/rmt/1m c 205 0x094080
So the following files should have the same minor number
/dev/rmt/c18t0d0BEST >> /dev/rmt/1m
/dev/rmt/c18t0d0BESTn >> /dev/rmt/1mn
/dev/rmt/c18t0d0BESTb >> /dev/rmt/1b
/dev/rmt/c18t0d0BESTnb >> /dev/rmt/1nb
Best of Luck
thanks
