[OpenIndiana-discuss] Multipathing help

[Russell Hansen]

After a bit of Googling I found the following.  Hope it helps...

"Use of the DS3500 with Solaris MPxIO requires special firmware on the array, which your IBM rep can provide to you. Once this was flashed onto the storage processors, the VHCI layer was able to coalesce the multiple device paths into a single instance. The DS3512 now identifies itself as model 1814 (what is that?) instead of 1746."

Did that, but it did not work

root at fs:~# stmsboot -D fp -e
STMS is already enabled. No changes or reboots needed

But I still can see eaxh drive on each path.
