1st device: Tape drives - HP LTO Ultrium-2 drive
2nd device: Medium changer - Unknown medium changer.
when i try to look for driver update, there is nothing found. on hp drivers page for the MSL2024 i can find 3 packages. one for LTT utility, one for firmware and one for uninstalling. i have succesfully installed the newest firmware few days ago, restarted both, storage device and whole server too. medium changer is still not recognized and cannot be used in Legato backup utility...
autochanger is enabled manually on the tape library, during the boot it is recognized under the scsi controller, tape library has LUN 0, the changer has LUN 1.
how can i make it working properly.
Solved! Go to Solution.

Re: unknown medium changer
acc. to your attachment, the changer is connected to windows machine. i also see changer as unknown media changer in our server. but legato works. can it be that you didn't run jbconfig from command line ?

Re: unknown medium changer
i didn't run jbconfig from command line. i came to server with the tape allready installed like i wrote before. im unable to find out what was allready done about the tape before...
when i try to enable autochanger in legato, i get the error message shown in this attachment.
do u have an idea how to continue from this point?

Re: unknown medium changer
in device manager only one tape driver is shown. i don't know how many drives acctually you have. if two you have hardware problems because of scsi connections maybe.
# inquire command list you scsi devices.you can run this command.
if you have one drive really and legato gives an error about missing drive, in legato administrator delete the autochanger and reconfigure it.

Re: unknown medium changer
What kind of MSL2024 do you have? The library can have 2 drives or 1 drive when running LTO 2. I'm assuming you only have one drive installed from your message. For some reason Legato thinks you have 2 drives so we need to figure out why.
Could you please run "Restore Defaults" from the web interface and see if that resolves the issue?
