Juan,

You can make the device files yourself and name them anything you want. Just follow the attached procedure.

OK, I'll paste my procedure in case someone else can't open the attchment:



1. Use "ioscan" to find out what the current device files look like and what the instance number is:
ioscan -kfnCtape


2. Use "mksf" to create each of the four types of device files:

/sbin/mksf -d stape -I 12 -a -b BEST rmt/12m
/sbin/mksf -d stape -I 12 -u -b BEST rmt/12mb
/sbin/mksf -d stape -I 12 -a -n -b BEST rmt/12mn
/sbin/mksf -d stape -I 12 -u -n -b BEST rmt/12mnb


3. Use "ll" to compare your newly created device files with those created by the system. Major and minor numbers
should match between corresponding entries (205 0x061000 for both 12m and the equivalent c6t1d0BEST):

ll /dev/rmt |more

crw-rw-rw 1 bin bin 205 0x061000 Mar 17 08:40 12m
.
.
.
crw-rw-rw 1 bin bin 205 0x061000 Mar 17 08:40 c6t1d0BEST
.
.
.



4. repeat the ioscan to double check that your new device files are associated with the correct tape drive:

ioscan -kfnCtape



I was using 12m in the example but you can use anything you want.




I know that's not going to format very well - that's why I attached it - sorry.

Juan,

Take a look in /dev/rmt at all the tape device files listed. I've seen past occurrences where device files were created manually in that directory. That prevented the system from creating the appropriate device files for a tape drive. Go through and rmsf the device files for all tape drives on the system. Look at /dev/rmt directory again. If there are any devices left, manually remove them and try creating the device files once again. I just ran into this problem last month.

Regards,
Eric
