I would like to share an info for those of you who happened to install RHEL 4 (Red Hat Enterprise Linux 4) and has trouble finding the HP DAT 72 tape drive.
My hardware specification :
- HP ProLiant DL380 G3
( with HP Smart Array 5i RAID controller - cciss )
- HP StorageWorks DAT 72h (hot plug)
( plugged to the HP Smart Array 5i )
I installed RHEL 4 and was surprised to see that my tape drive was not detected. I re-traced "dmesg" and confirmed that it's not there.
I had no previous problem with my RHEL 3.
After 30 minutes of search here's the solution to the problem.
Step by Step:[list=1][*]First try to see with :
( if you have no error message, then you are good to go )
[*]Do the following :
# echo "engage scsi" > /proc/driver/cciss/cciss0
# echo "rescan" > /proc/driver/cciss/cciss0
[*]Check dmesg again
[*]Verify that you should have /dev/st0 and /dev/tape hardlink-ed to it
( automatically created for you )[*]Finally put the above 2 echo command to the /etc/rc.local so that it will be executed everytime the system start.[/list=1]
The above can be applied to any tape drives connected to the Smart Array 5i (cciss).
Hope it helps ...
