Problems with HP LTO 230
Hi,
Firstly apologies to all those that assisted me previously, without me assigning points for the responses I got. You have my sinciere apologies.
I have an HP Ultrium 230 on an IBM machine running RH 7.3. (2.4.18-27.7) At random intervals, the LTO "disappears" from the OS. I usually do a rmmod st and then an insmod st to get the LTO back. The last time round, this did not work. Rebooting the server also sorts this problem out. In addition, the performance of the LTO is behind compared to what the documentations indicate. The LTO is on a separate SCSI controller to the disks.
Any help will be most welcome.
Thanks

First of all check this :

Guys speaking about patching 2.4.18-.
And please post /var/log/messages lines when all this happens.

Re: Problems with HP LTO 230
Well,some more info -
ultrium 230 is actually cerified by RH.
http://hardware.redhat.com/hcl/?pagename=details&hid=4822
More notes:
* Tested on an Adaptec 7892A SCSI controller. Other controllers should work as well.
* Manual configuration required:
* Add to /etc/modules.conf
post-install scsi_hostadapter modprobe st
* Tape changer can be controled from software (see: man mtx) after issuing the command:
echo "scsi add-single-device A B C D" > /proc/scsi/scsi
Where:
A = Hostadapter ID (first is 0)
B = SCSI Channel (First is 0)
C = SCSI ID of tape drive.
D = SCSI LUN of tape changer (use: 1)
* Use /dev/sgX for the tape changer, X is determined by looking at the location of the changer device in the output of /proc/scsi/scsi. If the changer is the 3rd device listed, the correct device would be /dev/sg2.
