Drivers not detected by Netbackup ( and scan.exe ) but ok in Device Manager

Drin
Not applicable

Hello,

I'm having REALLY BIG problems with Veritas Netbackup 6.0MP2 on a Windows 2003 server as a Media Master. I had a DELL PowerVault 136T connected through FC to 4 Media Servers, everything went smooth until : a new tape library was bought, a DELL TL4000. After I added this tape to the FC zone and installed drivers, strange things started to happen :

The MISSING_DEVICE problem : somehow, the older IBM ULTRIUM III devices are not beeing recognized anymore by scan -all, Tape3 and Tape4 now are replaced with IBM ULT3580-TD4 devices. From here, the serials are confusing Netbackup and I have MISSING_DEVICEs on each media server.

Rebooting the server doesn't help ... I tried to delete the registry by and and remodev all Tape* entries, but after setting all up and the next reboot ... the same problem again.

In device manager the drivers are looking ok. For all 7 Tape drives.

How can I make the scan.exe to permanently see the IBM ULTRIUM III Tape devices, so I can fix the mess created ?

I'm posting also the output of "scan.exe -all"

Drin,
 
We *had* the same problem.  When using IBM LTO-3 drives, use the IBM drivers, which must be installed throught a DOS promprt.  The script gives you 2 choices, exctape and magtape.  Choose magtape.  The exctape are drivers optimized for Tivoli - which look good in Device Manager, but cause NetBackup heartburn.  Also, we are using the 6138 release (old but still works).  The newer release I have not had too much success with.

Hello,

I'am not familiar with scan.exe. What does it do ? The output looks like the devicedatabase.

You should do the following:
    - Install Hardware and devicedrive in windows server. Do you have persistent binding ? If not it would be a good idea.
    - Windowstapedriver are available from hadwarevendoe and from Veritas. In case of quantum SDLT you should use Veritas driver. I think the same occurs for LTO. Never use IBM-tape-diver for Tivoli. (Failover-path etc.) these driver are for IBM-LTOs only and will work only with TSM
    - Delete all devices in Netbackup (You have entries with wrong serialnumbers) and syncronize database between all Mediaservers.
    - Install Devices at Master-media-server only using the wizard.
    - Share all drives.
    - Install devices in Mediaserver using the wizard on media-master-server.

So you have a complete new Hardwareconfiguration. be aware about the tapetypes you have an the Storageunitnames.

Hi Drin,

your output does not show what you have written about your configuration.

Can you please resend your configuration?

I understand from you writings:

You have old LTO3 Tape Drives from IBM in an "old" library.  And you have new LTO4 Tape Drives also from IBM in a "new" library.

But in your output of scan.exe, I found the following:
A Dell PV 136T with 3 HP Ultrium 1 drives.
A IBM (perhaps DELL OEM) library with 2 IBM LTO4 Tape drives.

As the others have stated so far, here my recommendations:

Use the newest IBM tape driver from here
Use the correct HP tape drivers for the hp drives.

Enable persistent binding on your HBAs. Without it, you will get mixed up after each reboot. That can cause your problem, as the tape drive is on a new path after every reboot.

Check if the serial numbers of the tape drives are different on all drives for all libraries. I have not seen it, but perhaps those serials will be generated by the tape library and are the same on two different tape libraries. If so, this has to be fixed, as NBU identifies a tape drive by its SN.

Another question. You want to share the tape drives. Therefore you need a Shared Storage Option licensed  on all Media Servers for the right amount of tapes. So perhaps if you have licensed 3 shared tapes and now want to share 5, it will not work unless you upgrade your license to 5 shared tapes.

The last and now most important thing:

Please upgrade immediatly to 6.0_MP5! MP2 is realy outdated and has some problems in it.

If nothing works - please open a support case.

Thx.
Christoph
