[OpenIndiana-discuss] Multipath IO Dual LSI 9211-8i

[MATTHEW WILBY]

Hi John,

I'm not familiar wit this array. Did you enable MPxIO?

It would be useful to have the output from the following commands ->

stmsboot -L
cfgadm -al
mpathadm list lu

Thanks,

Matt

Subject: [OpenIndiana-discuss] Multipath IO Dual LSI 9211-8i


Have a system setup with dual LSI 9211-8i controller cards connected to a 
supermicro dual expander chassis  SC846E26-R1200B  This is a newer unit with a 
6gb expander.
With opensolaris build dev 134 the unit would boot and then just freeze. Take 
out of one controller and it comes up fine.
Upgraded to openindiana oi_148 and now unit boots all the way and seems to be ok 
but the performance of the array has dropped from 500mps to 100mps. I am testing 
13) 600gig 15k drives with 2 SSD's (log and cache).
When I do a test I do see both controllers accessing the drives. Shouldn't one 
controller be the primary and the secondary just waiting?

Also after this test, I rebooted the box and now it will not boot, it looks like 
it corrupted the boot drive.


Any help on this is much appreciated.

Thanks


John Bittner
