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;
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?
My boot messages look like this;
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.
hmm... looks good as far as i can tell... are you sure both paths are ok from hardware side? checked all cables and so on? is an active/active layout supported for the array?
Yep, triple checked cables. When I was at the data centre.
I'm not sure about the array being active/active. The RAID GROUPS are assigned to a specific array controller (CM0 or CM1 in my case), I can manually assign the RAID GROUP to either CM0 or CM1 which changes the "Access State" for the paths.
However, I'm not convinced this will automatically fail over if a controleer or HBA fails. I'll look at the array in greater detail.
We recently moved our netapp disks onto new infrastructure by attaching the new controllers to our fibre switch and netapp migrating the disks. Disks kept the same address. We originally had 4 paths, but after attaching the new controllers we had 8. Now I want to remove the old paths. But can't. ... (5 Replies)

I have been running some tests with solaris mpxio, dual-pathed to HDS SAN storage.
When I take a path offline, Solaris recognised this and a path is shown as offline in luxadm display <device>. However, it does not recover on reinstatement of the path until I run cfgadm -al.
Any ideas?

Greetings Forumers!!
I was given a T2000 with one, dual port, HBA card. The card had one fiber connection to the SAN and the former admin enabled MPxIO.
Yesterday, I learned that the other port was connected to the same SAN. This system is in another city so I don't have physical access to... (1 Reply)

Last week I read that VxVM won't work with MPxIO (i don't recall the link) and that it should be unconfigured when installing VxVM. Today I read that VxVM works in "pass-thru" mode with MPxIO and DMP uses the devices presented by MPxIO.
If I create disks with MPxIO and use VxVM to... (1 Reply)
Hi,
I have a quick question.
How can I see MPXIO statistics (like errors, how many I/O|throuput per path, ....) on Solaris 10? Does maybe a ready dtrace script exist (I do not have the knowledge to write one myself)?
I would be happy if somebody knows some good documentation/links (with... (1 Reply)
Hi All,

I found out that my system setting for mpxio-disable=yes. Sun recommend to change it to mpxio-disable=no and run stmsboot -e command.
But no one can tell will it affect the system or not and the system is sol-10 and using veritas volume manager and attached... (3 Replies)
