P400 and Ultium 448 SAS

[Langer Robert]

Hi,

I use a brand new ML370G5 with two P400 SAS-Controllers (Dez. 2008)

Four Harddisk an the Ultrium 448 on first Controller.
Eight Harddisk on second Controller.

OperatingSystem ist RedHat EL 5 64bit.
Kernel 2.6.18-92 (latest Version for cpq_cciss-3.6.18-23.rhel5.x86_64.rpm)


I use the latest Driver and Firmware:

P400-Driver: cpq_cciss-3.6.18-23.rhel5.x86_64.rpm from HP-Webside
P400-Controller-Firmware: 5.20
Ultium 448 Firmware: T61D
Installed HP-Smart-CD: 8.15


I use just the TAR command for the backup. (tar cvf /dev/st0 /my-files)



Following comes after rebooting the Server, it seems ok for me:

Dec 19 15:14:16 localhost kernel: scsi0 : cciss
Dec 19 15:14:16 localhost kernel: Vendor: HP Model: Ultrium 2-SCSI Rev: T61D
Dec 19 15:14:16 localhost kernel: Type: Sequential-Access ANSI SCSI revision: 05

Dec 19 15:14:16 localhost kernel: st0: try direct i/o: yes (alignment 512 B)



During the tar-backup one of the following Error ocours:


Dec 19 16:48:08 linsprech kernel: cciss0: aborting tardy SCSI cmd
Dec 19 16:48:08 linsprech kernel: cciss0: command could not be aborted.

Dec 19 18:22:39 linsprech kernel: st0: Error 10000 (sugg. bt 0x0, driver bt 0x0, host bt 0x1).



After these errors I use
# mt -f /dev/st0 status
/dev/st0: Input/output error

No backup ist possible now, til I reboot the server.


What's wrong ??

Any ideas ??

Hi Robert,

Don't put a tape drive on a RAID controller...

In the QuickSpecs for the server you'll see this:

"For the ML370 G5, HP recommends purchasing the HP SC44Ge HBA (416096-B21) for a dedicated SAS HBA for tape."

Cheers,

Hi Rob,

Thanks for your answer.

It should be possible to conect the 448 on the P400 Raid-controller:

It in the Hardware compatibility list for the Ultrium 448 you can read this:

I am facing the same issue...

And if HP's says that it is a supported config... It need to work, so does anyone have a solution for this issue?

I need to put it online asap:(

My system is a HP DL360 G5 with a HP 448 SAS in an external case.
