This issue has been solved. See solution.

HI,

At the moment we have 4 devices tape LTO3 (ultrium product) and we added 4 devices tape LTO6. My problem is the scan command detect 8 drives but the wizard configure storage devices doesn't detect any new devices tape. Please find below the result of scan and tpautoconf command :

# ./scan

there are only 4 drives are detected and one robot in scan and tpautoconf command..

and the robot is contoroling the 8 Drivers but only 4 are connected to the server that you ran the scan command.

so you would probably need to check again in Zoning level and also check if they are visable in OS level.

SOLUTION

No, the scan command is detecting x4 drives, and the robot. The list of x8 drives you see is part of the robot output, showing only that the robot contains x8 drives, not that x8 drives are seen by the server.

Multiple possible causes, but check zoning first. Until the OS see the drives, forgot about trying to configure NetBackup.

What do you see in /proc/scsi/scsi

If you are using Qlogic HBA you should use SANsurfer utility to check if the HBA can see the new LTO devices. Emulex has a tool similar but I can re-call the name of it :-(

http://filedownloads.qlogic.com/files/ms/49541/ReadmeSANsurferFCmgr.htm

Assumption is the mother of all mess ups.

If this post answered your'e qustion -  Please mark as a soloution.

If I remember correctly, The Emulex software is called HBAnywhere.

Excellent idea Nicolai - this software IS the best way to see what is visable to the server, it 'looks' down the FC and shows what is hanging off the end.

Oddly, I've I've never worked out why, the majority of ttimes I've looked at an issue similar to this, I've found that they haven't got the software installed.

Do you think that the OS detect my new drivers ?

Marianne's picture

Nope!

You can see that the robot and only 4 LTO-3 drives are seen by the OS:

Vendor: IBM      Model: ULTRIUM-TD3 

The rest are disk drives.

As per above excellent advice: Check zoning and HBA software.

thank you. I'll check the zonning and HBA software.
