I have OpenIndiana oi_151a5 running on a system based on the
SuperMicro X9DAi motherboard
(http://www.supermicro.com/products/motherboard/Xeon/C600/X9DAi.cfm)
which is based on Intel's latest C602 chipset. The illegal request
counts have been incrementing (apparently in small bursts) for my two
SATA boot drives, which are now from two major drive vendors but
seeing similar requests. According to the blog entry at
https://blogs.oracle.com/chrisg/entry/iostat_e_whats_that_all, the
soft error count should increment if the illegal request count
increments. However, this is not happening in my case. I have
collected a very large log file using scsi.d (including when the
illegal request counts incremented several times) and have not found
any evidence that the drive itself reported an illegal request or that
any errors are occuring at all.
Are illegal request counts also incremented based on events at a
higher level (e.g. due to behavior of the AHCI device driver)? What
might be causing the illegal request counts to increment? Is this a
common/known issue or is it related to my bleeding-edge motherboard?
