LTO-5 storage error

We have moved our BE16 from a W2k8r2 server to a WS16. All backups and setting are great expect the LTO-5 drive.
The LTO was moved from the old server to the new one, but with new SAS card and cable.
The device is an HP Ultrium 5-SCSI with ( Z6ED ) firmware. The SAS card docs prefer (Z6DW) firmware, so I ran "HPE Library and Tape Tools" for a test. All was passed, so the hardware looks good.

In BE I see a storage error message:
"
Backup Exec 58053
Backup Exec Alert: Storage Error
(Server: "S-XX-XXXX") The device state has been set to offline because of an I/O device error.
Ensure that the drive hardware is turned on and is properly cabled. After you correct the problem, right-click the device, and then click Offline to clear the check mark and bring the device online.
Check the event log for information about the SCSI sense data that caused the error. For more information about SCSI sense errors, see the device vendor's documentation.
"

We removed the device and add again, we deleted directly form the database and add again and so on but the issue is permanent.

My very last idea, I will try to move the old SAS card and cable form the old server to the new one, but before I will do this, I try to find solution in this forum.

- The Old card is a HP H221 HBA
- The new is Adaptec HBA 1000 8e
- The BE version is BE16FP2
- The drive is HP LTO-5 Ultrium 3000

Has anybody any idea what could be the problem or what could be the solution?

Re: LTO-5 storage error

The Adaptec HBA you mentioned appears to NOT be a RAID HBA, which is good.  That means it should be supported per http://www.veritas.com/docs/000038683

But, the string of errors in your adamm.log and the fact that you believe the tape drive is healthy, sure make me suspect that SAS HBA or the HBA driver is cuasing trouble.  If you are already using the latest driver and firmware, I think you are on the right path to try a test with the old HBA.

Re: LTO-5 storage error

Are you trying to run a newly created job when you see this error, or a migrated job that was created in the original installation?

If it is a migrated job then it may be because we now identify the device as different (because of the OS and server hardware changes) and the migrated job may be trying to reference the old id and understandably is not able to communicate with it.

If new jobs work then you will either have to edit and re-target all your old jobs, OR as a worse case scenario, delete and recreate them. Once no jobs target the old device, if it is visible as offline in storage then you may need to delete the reference to it.

 

Re: LTO-5 storage error

You also might want to review the ADAMM.LOG

Info on how to do his is available here

Re: LTO-5 storage error

The problem appeared before any job. When I opened the surface the error was there.
After that I triede to run a simple "inventory now" with a tape but it was not worked.
Beside that we replaced a job's target to our DXI and later back, but nothing changed.

 

 

Re: LTO-5 storage error

I tried to copy spme lines which could be important and I encosed the relevant part of adamm.log
I see PDDM erro and invalis SCSI functions. If the drive looks OK why I got this messages?

Re: LTO-5 storage error

The PDDE error can be ignored as it relates to attempting to find a deduplication device (and as  I suspect you are not using that feature the error is expected)

This combination is you problem though

If you look in the Windows Event logs (System and Application) for the same times as these errors, do you see any issues with hardware being reported within the OS?

 

 

 

Re: LTO-5 storage error

In the adamm.log I see :

[08820] 08/09/18 14:57:21.751 PvlDrive::ReadMediaHeader() - offline device
       Drive = 1021 "Tape drive 0001"
       ERROR = 0x0000045D (ERROR_IO_DEVICE)

The System log did not contain any error in that time.

In application.log I see some error a bit earlier and the storage error what I posted at first.

[8820] 08/09/18 14:57:21 ADAMM Event:
Device: HP      Ultrium 5-SCSI  Z6ED
CDB operation code = 0x8
Sense key = 0x0
ASC = 0x0
ASCQ = 0x0

As the LTO test passed, and the drive operated well a few days ago in the old backup server, it could be an incompatible issue between the LTO and the SAS card? If yes why LTO test passed.

Re: LTO-5 storage error

So, today we replace the adaptec HBA tot the old HP H221 HBA. As we replaced the driver to  the correct one all LTO process started to work immediately.

I can confirm the Adaptech HBA did not operate with our LTO-5 drive under BE as expeced however the LTO test was fine.

Many thank for your help.
