v9 Tape Inventory Error

[hoFFy]

After installing v9 and using brand new Tandberg LTO-5 and LTO-6 drives and tapes (newest driers and firmware) on seperate vSphere-Hosts I was unable to do an inventoriation, error message in german was "unzulässige Funktion" in english it might be "function not allowed"

The solution was to change the block size from the default value 1048576 to 65536

[Gostev]

Thanks for sharing. Glad we added the capability to change block size!

[hoFFy]

I like your humor But I don't believe that its intended to fail if the drive is used "out of the box" without adjusting the block size, isn't it?

[Dima P.]

Hi Sebastian,

Can you clarify is that two separate standalone tape drives or two drives within one tape library? Thanks

[hoFFy]

Two customers, each with a new new SAS-attached Tandberg LTO (5 and 6) drive. One customer became a new vSphere Host, together with a fresh VM for Veeam 9, the other one got a new drive and Veeam has been upgraded to v9 (don't now exactly if upgraded, a colleage did it)

[Dima P.]

Thanks. To clarify was that a brand new tape media or media that was previously used by us (or any other tape software)?

[hoFFy]

The tapes were brand new

[Dima P.]

Thanks Sebastian. May I ask you to open the case - we want to check the logs to be sure.

[Y2kovu]

Got another seemingly confirmed case (pending a stretch of observe-and-report to follow) where setting the block size to 65536 on a standalone tape drive, this time a Quantum Ultrium LTO5 attached via SAS, was what resolved this issue. Internal support, refer to case 01673028.

I wanted to share with everyone in case you had other customers call in with this problem:

Backup Fails with Error:
WriteTapeHeader failed incorrect function. Tape read error Incorrect function. (Error occurs right after the tape is mounted)

The fix for this was to go into the properties of the tape drive (Tape Infrastructure / Libraries / ADIC Scalar i500 660G (<-- this is my Tape Library yours may be different) / Drives) and change the Block Size from ***** to 65536 (I have not tried any others you may want to experiment. The setting for the Block Size was 1048576.


Notes:
1) Hardware Used: Quantum Scalar I500 / IBM Ultirium-TD6 LTO-6 / Firmware Level E6R6 / No FC i/o Blade Connected
2) Backup Software used: Veeam
a. Cause of the problem: Upgrade Veeam from 8.0 to 9.0 (I am not for sure what the block size was set to in Veeam 8 by default but Veeam 9 sets the blocksize by default to 1048576)
3) Setup: Drives are set up in Point-to-Point Mode Connected to a FC Switch. FC Switch is set to Zone only the Fiber of the Tape Drives and the HBA in the ESXi Server. The Guest in the ESXi Server is a Windows 2k12 OS with the Tape Drivers loaded. The Virtual Hardware of the Tape drive includes the Library and each tape drive as SCSI devices.
4) To have this configuration work as it is unsupported by VMWare: Once the system is online load tape media into each drive / rescan the HBA and then ESX will enable the path for the drives. Once that step is completed turn on the guest and the guest will control the drives.


Hope this helps someone

So I upgraded to the latest version of veeam and since then I can't get my backup to tape, I get the following error.

Code: Select all

WriteTapeHeader failed Incorrect function. Tape read err Incorrect Function.

Anyone have any ideas? Thanks

Hello!
Please provided your support case number as required by the forum`s rules.
One of our customers had a similar issue which was solved by changing a block size, but I would suggest contacting technical support first.
Thanks!
