It seems your OS is not detecting the robotic arm. Inquire should show the Autochanger also apart from the two drives.

Currently your drives are working as standalone drives.

Please check.

Yes, that is correct. The backup works after mounting a tape manually.
But what can i do to detecting the autochanger by inquire? Is it a driver problem?

Yes this is a drivers problem.

You can consult your Sun support to get this checked at the OS level.

Hi Anuj,

we had some issues with Solaris 10 and Emulex HBAs and downgraded to Solaris 8 after that. Is this the drivers problem you're talking about? Do you know if Sun support is able to solve the problem?

If it is working on Solaris 8, the HBA drivers & firmware may not be the right ones for Solaris 10.

Well, this is not an answer to bring me forward.

I found a document on sun.com website related to Emulex HBAs, inquire and Solaris 10 that - according to Sun - should solve my problems. Actually it didn't.

after changing the control port from scsidev@3.0.0 to /dev/scsi/changer/c3t... the jukebox is now working.

i'm running into this situtation now. Could you please tell me exact steps for changing control port.

much appreciated your help.

Thanks,

Mallik.

With solaris 10 networker uses the persistent name for the control port. first you need check if the device control port is visible to OS. Check under /dev/scsi/changer for the control port reported by OS. Alternatively you can run "changers" command to list the changers.

Then either you can update the control port from NMC by changing it in the jukebox properties. Ensure that the jukebox is disabled before you change the control port.

Another easy aprroach is to delete the tape library configuration from nw and then reconfigure using the new control port.

Also refer to the technote for the same, which is available on powerlink.

Note: SJI commands may report error when networker services are running and the tape library is configured.

Thanks Mridual for reply.

in this case i'm able to see a control port unnder /dev/scsi/changer but actual path (../../../devices/pci@1e,600000/pci@3/scsi@5/sgen@0,0:changer)  doesn't exists at all.

# ls -la /dev/scsi/changer/
