HP 1760 SAS problems in linux
I hope some one can help me with this as I've been working on it for a long time. We have a DL380 G6 with optional drive cage installed. There is a P212 0 memory controller connected to an external HP 1760 SAS drive in a 1U rack mount enclosure. The server is running CentOS 5.5 with kernel version 2.6.18-194.el5 x86_64. The P212 has firmware version 3.00 and the cciss driver version is 3.6.22-8. The tape drive has firmware revision U52D. The problem is that I can't write more than 70GB to tape. We use amanda as our backup software but even using 'dd' to /dev/nst0 fails. I get kernel errors:
cciss: cp ffff8100df62d308 has protocol error
st0: Error 70000 (sugg. bt 0x0, driver bt 0x0, host bt 0x7).
and the write using dd or amanda stops. The drive itself has been replaced. Original purchase of the system came with a SC44Ge which didn't work either.
cat /etc/stinit.def
manufacturer=HP model = "Ultrium 4-SCSI" {
auto-lock=0
timeout=3600
long-timeout=14400
can-partitions=0
async-writes=1
mode1 blocksize=0 density=0x00
}
Does anyone have any ideas?
Thanks in advance.

Re: HP 1760 SAS problems in linux
Hi cdemmert,
Firstly to isolate that there is no issue with the hardware. You might want to download and run the Library and Tape tools. located at
www.hp.com/support/tapetools
or
http://h20000.www2.hp.com/bizsupport/TechSupport/DriverDownload.jsp?pnameOID=406731&locale=en_US&taskId=135&prodSeriesId=406729&prodTypeId=12169.
Reviewing the quickspecs of the DL 380 G6 server the Cent OS does not seem to be one of the support OS.
Link to server quick specs ::
http://h18000.www1.hp.com/products/quickspecs/13234_na/13234_na.pdf
Further, in the compatibility matrix for Server >> HBA >> Drive >> OS ::
http://www.hp.com/products1/storage/compatibility/tapebackup/ISS/Detail/16-0046-0190.html
Cent OS is not listed as supported OS for DL 380 G6 thought it might be based on an RHEL base.

Re: HP 1760 SAS problems in linux
Hi Ganz,
Thanks for your reply. I just finished a LTO Drive Assessment test which cleared with 'The test has PASSED and the drive is GOOD'. Is there a different test you think I should run?
As to the OS, we've been running it for years on other HP hardware and haven't had a problem yet. As far as I know the only difference between RH and CentOS are images and names.
Do you know anything about the kernel errors I've been getting?

Re: HP 1760 SAS problems in linux
Issue solved. I had the rack enclosure replaced and now that I've been able to write more than 750GB to tape I'm confident that the problem is resolved.
