setting a tape backup on CentOS 5

I would like to setup a Dell Powervault 114T lto 3 tape backup system on a CentOS 5 machine
Does anyone know of link to a guide / how to that shows how to set up a tape backup system to CentOS/Linux system.

under the scsi info the system correctly identifies the maker of these drives as IBM Ultrium td3

I have never installed a tape backup, so I know nothing.

thanks!! for any help

The trick is the auto changer.  The commands to control the robotics are vendor/product specific and you need backup software to do that.  (check out open-source product called amanda).

but if you didn't have robotics, then nothing to set up.  You would just enter tar cvf /dev/rmt (then list of directories and wild-cards) to copy to tape.

Thanks for the input, there is no auto changer. this is a Dell tape backup unit with 2 drives.

this is a tape backup system that I'm adding on to an existing system. I don't have any directory or file /dev/rmt

Biggest mistake people make when attaching tapes is assuming they can just plug it into any SAS / FC, or SCSI connector.  Your controller MAY only support RAID disks.  So if nothing shows up with cat /proc/scsi/scsi that isn't obviously a tape drive -- it will be obvious, trust me ...   then post make/model of controller you have.

The TAPE should also show up when you go to BIOS of the controller card on power-up ...if the  controller can see it.  So one has to make sure the hardware sees the tape before worrying about an operating system.
Your help has saved me hundreds of hours of internet surfing.

When I do cat /proc/scsi/scsi I get all the scsi devices attached to the computer which includes both tape drives in the Dell Powervault 114t unit .
Drive 1
host: scsi2
channel : 00
id:05
Lun:00
vendor: IBM
Model:ULTRIUM-TD3
Rev: 6b20
Ttype: Sequential-Access

Drive 2:
host: scsi2
channel : 00
id:05
Lun:00
vendor: IBM
Model:ULTRIUM-TD3
Rev: 5480

It's an Adaptec 39160 card and the drives do get detected at boot time. And as the info above seems to suggest the OS also see them.

Thanks!!
