Sun Traffic Manager problem
OS/ Version: Solaris / 5.8
Software: SAN 4.4.8 (SAN Foundation Kit)
I installed the SAN 4.4.8 Foundation kit to implement STMS in order to have a dual path to both an A5200 as well as thru the SAN to a Hitachi 9500V storage subsystem. After the installation of software and patches, I rebooted the server with mpxio disabled. I then modified the scsi_vhci.conf file to enable mpxio. I rebooted the server once more and then updated scsi_vhci.conf with the "device-type-scsi-options" info. Upon reboot, I still do not see the drives under mpxio control nor were any addl devices created. I do and have been able to see the devices via format. A stmsboot -L shows the device and the corresponding STMS device name but there are no links or devices referencing this name. I even did a devfsadm -Cv to clean the links and rebooted with reconfigure but still nothing. What did I miss? Does mpxio work on Solaris 8 using QLGC single HBA cards for the A5200 and JNI FCE-1473N cards for the Hitachi?

Can you see the storage from obp? Solaris only sees LUN numbers of 0 by default, you may have yo make some changes in /kernel/drv/sd.conf. Another thing, the JNI cards may not be supported with the SAN foundation software you are using, this software is developed for Sun FC cards. Is there an option to migrate to Solaris 10?

It wasnt clear from your post if you were hoping to get multipathing to just the A5200 or the 9500 as well.
But you should be aware that the 9500 is not supported by mpxio (STMS).
So you wont get multipathing to it.
You need to use something like vmvm DMP if you want to multipath a 9500.

Robert, where did you get the information about STMS not being supported on the 9000 series SANs? A search of the internal handbook on various models from the 9000 platform turns up no references to STMS being unsupported. Furthermore the 9000 series storage systems are " not customer manageable " systems, so any support and configuration questions regarding this platform should be directed to Sun Storage support.

Some of the info came from direct email with a sun engineer.However, heres a couple of threads that reference the issue. http://www.opensolaris.org/jive/thread.jspa?threadID=5888&tstart=0 http://www.opensolaris.org/jive/thread.jspa?threadID=5881&tstart=15
