Best guess would be non plain text (i.e. having html components). vger is pretty keen on eating those as part of its spam filtering.

The best docs we have is the source. LSI can provide the reference manuals under NDA.

You still need to turn off html email attachments, otherwise your messages won't be accepted by the mailing lists. It will be an option like recipient wants text/plain only or something.

Hi,
Sam many thanks for ur help.
Hi James,
I am getting some error on for fusion device driver. The error message look like this

I can see the code is written inside /drivers/message/fussion/ mptscsih.c
The responsible function is
mptscsih_host_reset()
i am very new in SCSI fusion device driver. read some help guide from google but still i do not understand when the mptscsih_host_reset() is called by kernel. I normal situation i am not able to see this message in kernel log.
Can any one help me to understand when these type of kernel message are comming, is it foe SCSI hardware problem ?
when mptscsih_host_reset() will be executed?

It looks like a standard error handling escalation sequence. Why is very hard to tell without the entire kernel log. Why there wasn't a recovery is also not clear.

Quoted 6 lines

Only one time i show this message in my kernel log, is there any way to reproduce this message manually?
where i get much info regarding this issue and SCSI fusion kernel driver except kernel code itself?

I am writting this after reading help doc from
http://www.lsi.com/insight_center/tech_trends/advanced_architectures/fusionmpt/index.html
But still i am very few knowledge to solve it.
waiting for your help.

There's not much else I can do. If you post the entire kernel log, the fusion people hang out on this list and might see something that indicates what the problem is.

HI James,

I got some idea about fusion driver from this link
http://bugzilla.kernel.org/show_bug.cgi?id=12195

And i found there is bug in fusion driver (kernel version 2.6.10) from this link
http://www.nabble.com/MPT-fusion-driver,-better-but-still-buggy-at-errors-handling-under-2.6-td1095505.html

Now it should be received by all...
Many many thanks for the help.

Hi,
Sam many thanks for ur help.
Hi James,
I am getting some error on for fusion device driver. The error message look like this
       2F240F4C226078: 19/12/2008 EST 04:42:45, mptscsih: ioc1: >>

After then the server has been rebooted.

I can see the code is written inside /drivers/message/fussion/ mptscsih.c
The responsible function is
mptscsih_host_reset()
i am very new in SCSI fusion device driver. read some help guide from google but still i do not understand when the mptscsih_host_reset() is called by kernel. I normal situation i am not able to see this message in kernel log.
Can any one help me to understand when these type of kernel message are comming, is it foe SCSI hardware problem ?
when mptscsih_host_reset() will be executed?
It looks like a standard error handling escalation sequence. Why is very hard to tell without the entire kernel log. Why there wasn't a recovery is also not clear.

yes its error handler sequence. But as describe into the above link(http://www.nabble.com/MPT-fusion-driver,-better-but-still-buggy-at-errors-handling-under-2.6-td1095505.html) that
2.6.xx xx <= 11, enters an infinit loop attempting to reset the SCSI
so the box gets unusable and requires a rough power cycle to recover.

So i think that is the reason to restart the server(after "Attempting host reset! )as a power cycle is required to recover.

when next time server was booting i got some kernel messages on recovery of SCSI. So recovery is done after reboot the server.

Still i do not know how to over come this bug fo infinite loop. If you have any suggestion please let me know.

Pls let me know when this kind of error handler is happened? is it for SCSI hard ware failure?

Only one time i show this message in my kernel log, is there any way to reproduce this message manually?
where i get much info regarding this issue and SCSI fusion kernel driver except kernel code itself?

I am writting this after reading help doc from
http://www.lsi.com/insight_center/tech_trends/advanced_architectures/fusionmpt/index.html
But still i am very few knowledge to solve it.
waiting for your help.
There's not much else I can do. If you post the entire kernel log, the fusion people hang out on this list and might see something that indicates what the problem is.
James

Thanks
