MSL6000 backup solution for linux

Hi, the HP MSL6000 tape library is working fine with Tru64 5.1B. But when we connect this tape library to the Linux system, we can't find the same program "robot" to work with the Linux system. The linux server is a Linux ES.

Where can I download a Robot program that works with MSL6000 that work with Linux?

here is the lsmod output from the linux server:
# lsmod

I don't see a st module running in the system. do I need a st module?

What is an easy way to get MSL6000 working with linux? where can I find a script for doing backup/restore using MSL6000 in linux?

Thanks

Hi Sam,

Just answered this in the Tru64 forum...
You need to be looking at mtx to control a library.

Cheers,

Take a look to bacula:

www.bacula.org

It has media changer support, I nerver tried with msl series.
Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?

Re: MSL6000 backup solution for linux

Hi,

Is there a way I can tell whether the MSL6000 tape library has tapes inserted in the slots?

Here is the content in the /proc/scsi/scsi file:

#cat /proc/scsi/scsi

Re: MSL6000 backup solution for linux

Hi,

I am not sure how to make sure the tape library is properly attached and whether there is any tape in the slot and which slot does each tape occupied. How do I know this info in linux?

this is the output from dmesg:

Re: MSL6000 backup solution for linux

Hi,

Here is some further information that I have explored so far:

# ./loaderinfo -f /dev/sg0
Product Type: RAID Array
Vendor ID: 'HP '
Product ID: 'HSV200 '
Revision: '6000'
Attached Changer: No
Bar Code Reader: Yes
EAAP: No
Transport Geometry Descriptor Page: No
Device Configuration Page: No
# mt -f /dev/sg0 rewind
/dev/sg0: Operation not permitted

With the output from running mt, is "operation not permitted" means there is no tape in the library?

Thanks
Sam

Hi,

The tapeinfo shown that there may be no tape attached to the library. Here is the the output from tapeinfo:

Vendor ID: 'HP '
Product ID: 'HSV200 '
Revision: '6000'
Attached Changer: No

Re: MSL6000 backup solution for linux

Hi,

Looking through the dmesg output, I don't see any mention of a tape device or changer...

The /dev/sg devices you've been probing appear to be your EVA not the MSL.

How exactly is the library connected ?

From your post on the Tru64 list, you mentioned that the MSL is shared with a Tru64 machine which implies it's connected to the SAN, probably via an NSR.

Maybe you haven't set the zoning up on your switches to enable the Linux box see the library...

Cheers,

Rob

Re: MSL6000 backup solution for linux

Yup, you are correct.
The zone is not setup for the linux farm yet.
