How to use HP MSL 4048 tape library?

Hi

We just got an HP MSL4048 tape library and had it connected to a rx3600(HP-UX11i v2)server via a SAN switch. After installing the kernel driver "schgr", ioscan lists 2 entries related to the tape library:

intg1.cdr-ss.com:/roothome # ioscan -fnkCautoch
Class I H/W Path Driver S/W State H/W Type Description
==========================================================================
autoch 0 0/2/1/0/4/0.1.2.255.0.0.1 schgr CLAIMED DEVICE HP MSL G3 Series
/dev/rac/c2t0d1
autoch 1 0/2/1/0/4/0.1.6.255.0.0.1 schgr CLAIMED DEVICE HP MSL G3 Series
/dev/rac/c4t0d1
intg1.cdr-ss.com:/roothome #

Now my question is how do I use this tape library to do backup using fbackup/tar? Did I miss anything here?

Thanks a lot in advance.

How about a backup application, e.g. data protector?

Hope this helps!

By the way, you see the same library twice.

Better to create a zone with only 1 path to the library to avoid confusion.


For simple tools like tar or whatever, you can use "mc" command or the web frontend to load a tape into the drive, then run such command.

Hope this helps!

Re: How to use HP MSL 4048 tape library?

This tape liabrary has 2 drives and I just used HP StorageWorks Library and Tape Tools(L&TT) to do Read/Write test on both drives and the tests passed.

But how do I access these 2 drives from HP-UX OS? Do I need to worry about the UNCLAIMED/UNKNOWN entries in the following ioscan output? Thanks a lot.

Re: How to use HP MSL 4048 tape library?

You need to configure the "stape" driver into the kernel.

# kcmodule stape=static

and reboot.

Hope this helps!
