AIT 35 LVD tape drive driver.
Hi LinuxQuestions.org
I have a Compaq AIT 35 LVD internal tape drive in my Compaq ML370 server with RedHat9 installed.
Problem
======
1. No device file where normally be /dev/rmt/0 is found. Hence system can not access tape drive.
Research result
==========
1. Found from redhat web site, found that RH9 does not bundle driver for this tape drive.
2. Log case to HP, I was told that the software on its web site is only a utility and no driver. Advised to use generic driver.
3. I found that "st" driver will not be loaded when reading the output of "lsmod". I am able to "modprobe st" and even "modprobe sg", but still there is /dev/rmt16 and /dev/rmt8 files only.
4. There is only 1 file called "scsi" at /proc/scsi, with content "Attached devices: none". However there are also SCSI hard disk that were RAID1. By right I should see some thing but not.
5. By doing testing "tar cf /dev/rmt8 /var" and "tar cf /dev/rmt16 /var" will get error message that is similar to "Cannot open: no such device".
6. The tape drive can be detected with the SCSI firmware utility before O.S bootup. It can be used in W2K before it was reinstalled with RH9.
Question
======
1. What type of device driver will be used for AIT 35 LVD internal tape drive? If generic driver "sg" is used, what should be the corresponding device file I should get and how should I build with device file using driver "sg"?
Kindly provide me assistance.
Thanks
