One drive that won't stay up

[Dan_Giberson]

I have a drive in my ADIC i2K that I can't get to stay up. I almost want to say it's a hardware issue, but the library seems to think the drive is fine. I have turned on the VERBOSE for the logging and see a couple of cryptic errors that i'm not sure are normal or not.

When I try to do a cleaning I get this:

16 2 2144775 0 srvlcnbs01 *NULL* nbjm NBU status: 98, EMM status: The media server reported a system error

This error really worries me....

Unknown robot number 1, from host srvlcnbs01

With my errors, I would expect this one:

TLD(0) [9988] GetTapeParameters for drive 1 (device 3) returned: The device is not ready.

THis is what I think the problem is caused by:

TLD(0) [9988] Unload requested, but no unload, drive 1 (device 3)

I have physically looked and confirmed that there is nothing in the drive.

If I use Robtest to move a cleaning tape to the drive for testing I get this:

TLD(0) key = 0x5, asc = 0x3b, ascq = 0xd, MEDIUM DESTINATION ELEMENT FULL

Any suggestions? I have physically power cycled the drive, the media server, and the Master server.

Running NBU 7.01 on W2K3

Just found this error...I think I need to delete the device and re-add it....

Fatal open error on HG_LTO_1 (device 3, \\.\Tape3): The system cannot find the file specified. DOWN'ing it

[AlanTLR]

It's possible it's a bad drive, seeing as it seems like it thinks it has media in it.  I would try removing it and re-adding it via the wizard to see if it rediscovers/resets the state to EMPTY.  Are you seeing any problems within your event log or the device manager/tree?

[Dan_Giberson]

Those errors are from the Event log.

[muhanad_daher]

i need this info plz:

master OS, Media OS, this error where you get from master or media server, Are you have seen tape deive down in GUI, are there any frozen media tapes.

[Yasuhisa_Ishika]

Can you provide us outputof following operation in robtest? s d s s m sX dX(move tape from slot to drive which you got reported as full) m dX sX(move tape from drive which you got reported as full) Also provide output of scan(volmgr\bin\scan) command.

[Michael_G_Ander]

Hi Dan

That can be caused by the driver not being loaded for that tape in the windows system

Some times a Update Driver Software can fix the isssue

Regards

Michael

Here is the s d output.

s d
drive 1 (addr 256) access = 1 Contains Cartridge = yes
Sense code = 0x83, Code qualifier = 0x0
Barcode =
drive 2 (addr 257) access = 0 Contains Cartridge = yes
Source address = 4483 (slot 388)
Barcode = 005320
drive 3 (addr 258) access = 0 Contains Cartridge = yes
Source address = 4260 (slot 165)
Barcode = 005500
drive 4 (addr 259) access = 0 Contains Cartridge = yes
Source address = 4467 (slot 372)
Barcode = 005321
drive 5 (addr 260) access = 0 Contains Cartridge = yes
Source address = 4466 (slot 371)
Barcode = 005322
drive 6 (addr 261) access = 0 Contains Cartridge = yes
Source address = 4389 (slot 294)
Barcode = 005474
READ_ELEMENT_STATUS complete

You can see that it thinks there is a tape in the drive (Drive 1) even though there physically isn't.

I can't provide the s s command as I have a 400 slot library and that will take a while.

 Here is the move error:

m s291 d1
Initiating MOVE_MEDIUM from address 4386 to 256
move_medium failed
sense key = 0x5, asc = 0x3b, ascq = 0xd, MEDIUM DESTINATION ELEMENT FULL

Here is the scan out put.

[Dan_Giberson]

Do you recommend the Symantec driver or the Quantum driver?

[mph999 · Accepted solution]

Hi Dan,

What you see in Robtest is 100% for certain sent from the library.

Therefore, it is the drive/ library that is having the issue not NetBackup.  No amount of poking, prodding or tickling NetBackup will clear this.

NetBackup does not 'look' in a library, it actually asks the library, show me what is in the slots/ drives etc ...

So, to resolve this issue, forget NBU and look at library / drive issues.

I would recommend a powercycle of the drive (a proper on/ off, not a reset from the library console).  If this does not resolve, power cycle the whole library, if this doesn't work, I afraid it is time to log a hardware call.

From this link http://www.symantec.com/docs/TECH169477

Library Inventory Issues

NetBackup up does not directly 'Inventory' a library. Instead it queries the library and waits to be told what tapes (barcodes) are located in which element address (slots/ drives). If, for example,  NetBackup 'cannot see' a particular cartridge(s) it is because the library is 'hiding' the location, not because of any setting within NetBackup.

For example, common symptoms of library issues include tapes appearing in the incorrect/ wrong slot, and tapes/ slots  not appearing at all.  It is impossible for this to be caused by NetBackup.

To further investigate Library issues, Symantec recommends contacting your hardware vendor.  

Although this isn't quite an invemtory, this description from the TN is close enough to be valid.

I hope this helps,

Martin

PS.

Also, ASc/ ASCQ errors as seen (sense key = 0x5, asc = 0x3b, ascq = 0xd) are also sent from the hardware and are only displayed by NBU.  The technote also covers these.

[Yasuhisa_Ishika]

Can you try to move this ghost tape in the drive to some empty slot? Try and check if physical tape is moved to destination slot.

As Martin wrote, robtest just displays info/code provided by your library. If the drive is really empty, there are something wrong with i2000.

[Marianne]

 No amount of poking, prodding or tickling NetBackup will clear this.

LOL! Really enjoyed your EXCELLENT post, Martin!

Thanks Marianne   ;o)

Swapped out the drive. All good now.
