For all of those suffering from mpt timeouts in snv_127, I decided to
give the ancient itmpt driver a whirl. It works fine, and in my brief
testing a zfs scrub that would generate about 1 timeout every 2 minutes
or so now runs with no problems.
The downside is that lsiutil and raidctl both fail to work :-(
I also tried the mpt driver from Solaris 10 x86 patch 143129-01, but
that fails to load with undefined symbols, as do the mpt drivers from
snv_111b and anv_118 (unless I got something wrong with my bootadm
update-archive invocation...)
For reference, I'm running firmware 1.29.00.00 (the latest), and the old
errors were of the form:
Nov 19 03:34:43 gandalf.taltos.org scsi: [ID 107833 kern.warning]
WARNING: /p...@0,0/pci8086,2...@1c/pci1000,3...@0 (mpt0):
Nov 19 03:34:43 gandalf.taltos.org Disconnected command timeout for
Target 13
With the target number changing. When the hangs would happen, iostat
would show "stuck" I/Os on all 8 SATA disks attached to my controller
(which are all in the same raidz2 pool)
