Q:

I ran into a customer that has a Sun 280R (with Solaris 9 well patched)
and two (2) LP8000-E Emulex HBA’s. Despite several attempts (including
following the instructions provided in the latest STM/MPXIO configuration
guide to the letter), I can’t get MPXIO to encapsulate the multipathed
disk devices coming in over the two HBA’s. Has anyone had success in
doing it with the lpfc (Emulex driver)?

Here is my configuration:

========================================
======================
format(1M) output: MPXIO doesn’t encapsulate the last two
devices (2 & 3) into one virtual device.

Note: The last three lines, per the STM config doc,
were necessary to configure support for the 3rd party
RAID devices (which, in this case, is a Clariion FC4700).

Thanks in advance. Appreciate it.

A:

MPXIO only works with fibre devices using the ssd (Leadville) driver.
Emulex, and JNI (non-SUN) use the regular SCSI driver (sd) instead of this
one. You’d need an Sun JNI (jfca) of a Sun QLogic card that use the ssd
driver for mpxio to work.
