Backup - Data Phase Error

Running SLES8 on DL380 with a SCSI HBA connected to an ADIC i2K with 2 LTO-2 drives.
Using Networker as backup software.

Backup is running fine on 1 drive, but when it hits the other drive, it would be unable to recognise the tape, or it would marked the tape full prematurely.
Now it gotten to the stage where the good drive is not responding well too.

Only relevant error I can is
kernel: SCSI Error: (0:3:0) Status=02h (CHECK CONDITION)
kernel: Key=Bh (ABORTED COMMAND); FRU=30h
kernel: ASC/ASCQ=4Bh/00h ""
kernel: CDB: 08 00 00 80 00 00 - "READ(6)"
kernel: st1: Error with sense data: Current st09:01: sns = 70 b
kernel: ASC=4b ASCQ= 0
kernel: Raw sense data:0x70 0x00 0x0b 0x00 0x00 0x00 0x00 0x1c 0x
00 0x00 0x00 0x00 0x4b 0x00 0x30 0x00 0x14 0x31 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x
00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x03 0x01

SCSI HBA is from LSILogic with /proc/scsi/mptscsih
ioc1: LSI53C1030, FwRev=01032300h, Ports=1, MaxQ=255

I thought it might be firmware issues, but I have another identical setup running fine.

Any ideas or leads? thanks!

Re: Backup - Data Phase Error

It seems to me morelike be a hardware rupture in the scsi bus/chain, or a device sending garbage on the the bus.

Does a
#more /var/log/message
and a
#demesg | more
not tell you more ?


Smile I will feel the difference

Re: Backup - Data Phase Error

Have you solved your problem ?
I have got exactly the same :
DL380 with an Addic (mine is Scalar 100) with 2 LTO2 tape.
Same messages .
I have updated the DL380 Bios, the scsi card firmware, upgrade the RedHAt version, verifying the connectic,...
I have four opened cases Hp,Veritas,RedHAt,Addic and nothing is clear.

Please tell me if you have found a solution.

Re: Backup - Data Phase Error


Wanted to monitor the issue more before posting back here.

Previously, I changed the HBA, changed tape drive even reinstalled SLES, but problem comes back intermittently.

Final change was the SCSI far, its been good. So likely its a faulty SCSI cable...

Hi Steven ,
Thank you for the answer.

I have change Scsi cable, HBA ( LSILogic -> adaptec) , upgrade the Linux Kernel , and nothing change.
Finally i bought new Fuji cartridge ( formers where Imation( not recommended by Adic ) ).
And it works since yesterday with new cartrige.

I am very surprised that about 15 cartridge can have bad quality.

Perhaps another problem dammaged cartridge .
I have to check that.

Re: Backup - Data Phase Error

I had used tapes from all the far all ok.
Did you contact Imation abt it?
The Imation rep for me had been very prompt and helpful when a colleague of mine encountered bad blocks on tapes (this happened also with other vendors, but Imation response was the best)

The other thing that I just found out was a SCSI probe from Legato networker also caused some issues. Need to use the probe with an option.

Re: Backup - Data Phase Error

In france it's not easy to join Imation by phone (always busy) but I have contacted them by mail and they want me to send 10 of my cartridges to check.

I will see.
