Hi,
I have an Oracle/Sun T3-2 Server with a duel SAS controller Fujitsu DX60 array attached.
I have 2 x SAS HBA's in the T3-2. One HBA cabled to CM0 and one HBA cabled to CM1 of the array.
The array is setup with one RAID GROUP and one VOLUME and one LUN
In Solaris I can see one device under format and mpathadm see the paths to o the LUN.
I want to test failover before I continue building this array. But path failover is failing;
bash-3.2# mpathadm failover lu /dev/rdsk/c6t600000E00D0000000003142900000000d0s2
mpathadm: Error: The logical unit doesn't support explicit state change.
mpathadm: Unable to complete operation
bash-3.2#
My paths look like this, note I have an "active not optimized" path, all the docs I have read would suggest the Access State should be active or standby. So what does my Access State of "active not optimized" mean?
bash-3.2# mpathadm show lu /dev/rdsk/c6t600000E00D0000000003142900000000d0s2

I have not edited any /kernel/drv files nor had to stmsboot, this is a new install, thus far everything has been dynamic.
If you guys could help me test my path failover that would be great.
Thanks,
