Hi Cesare,
According to our CR 6524163, this problem was fixed in PowerPath 5.0.2,
but then the problem reoccurred.
According to the EMC PowerPath Release notes, here:
www.emc.com/microsites/clariion-support/pdf/300-006-626.pdf
This problem is fixed in 5.2 SP1.
I would review the related ZFS information in this doc before proceeding.
Thanks,
Cindy

Thanks for the info Alexander... I will test this out. I'm just wondering
what it's going to see after I install Power Path. Since each drive will
have 4 paths, plus the Power Path... after doing a "zfs import" how will I
force it to use a specific path? Thanks again! Good to know that this can
be done.
I had in the last weeks a similar problem. I have on my testbed server
(Solaris 10.x Update4) PowerPath 5.2 that it's connected on two FC
switch and then to Clariion CX3.
Each LUN on the Clariion create 4 path to the host. I created 8 LUN,
reconfigured Solaris for make them visible to the host and then tried
to create a ZFS pool. I encountered a problem when I run the command:
--
# r...@solaris10# zpool status
pool: tank
state: ONLINE
scrub: scrub completed with 0 errors on Mon Dec 14 05:00:01 2009
config:

mirror ONLINE 0 0 0
emcpower7a ONLINE 0 0 0
emcpower5a ONLINE 0 0 0

emcpower8a ONLINE 0 0 0
emcpower6a ONLINE 0 0 0

2009-12-11.14:28:33 zpool add tank mirror emcpower8a emcpower6a
2009-12-14.05:00:01 zpool scrub tank
r...@solaris10# zpool add tank mirror emcpower3a emcpower1a
internal error: Invalid argument
Abort (core dumped)
r...@solaris#

Next task will be to upgrade PowerPath (from 5.2 to 5.2 SP 2) and then
retry the command to see if the problem (internal error) will be
disappear. Anybody did have a similar problem?
Cesare
