aacraid, seagate and adaptec issues [Was: Re: Fw: [Bugme-new] [Bug 3651] New: dell poweredge 4600 aacraid PERC 3/Di Container goes offline]

[Otto Solares <solca@guug.org>]

FYI again:

There is a recent KernelTrap thread showing more datails:

http://kerneltrap.org/node/view/3778

Investigating I found 2 more things I'll check:

A seagate time-out issue with exactly my disks:

http://www.seagate.com/support/disc/u320_firmware.html

Unfortunately adaptec will not give me directly the firmware
and Dell does not respond to my support mail queries.  I'm really
impressed with Dell support, they suck so badly, at least
those updates must appear in their download area.  I am pretty
sure my next servers will not come from Dell.

Does anybody have this seagate firmware updates?

And the other issue is a different driver from adaptec:

http://www.adaptec.com/worldwide/support/driverdetail.jsp?sess=no&language=English+US&cat=%2FOperating+System%2FLinux+Driver+Source+Code&filekey=aacraid-src_1.1.5.tgz

Diffing the adaptec and latest 2.6 kernel show they come from
the same base but it seems more complete the Adaptec one,
does somebody knows the difference?  The important thing is
which is better for heavy I/O servers?  Why two drivers?

Thanks.
