There was a comment placed in a Sun-private section of the bug: sorry
about this, it's against the policy. As the reason the bug was closed
was bogus anyway, I've re-opened it for you.
are you still having an issue with this? it seems to me that the LSI
megaraid is having some issues with a higher queue depth .. by
limiting the device queue (vdev_max_pending) or file prefetch queue to
1 you're making the problem go away
also the "page83 not standards compliant" message has to do with what
the vendor reports for the array controller (VPD = vendor product
data .. page83 tells us some useful information about multipathing) ..
do you have MPxIO enabled or no? This is going to push the problem
down to the sd device, but it seems like you're saying that reads here
are acceptable.
