I have a T2000 with 4gb dual port qlogic hba port and a 3510FC array
with one controller (upper board) attached to it.
I do have mpxio enabled on the host but I only see one path
# mpathadm show lu /dev/rdsk/c4t600C0FF0000000000A758B0FE1935B00d0s2

I noticed the hba is connected to fc0 and fc1 on the storage
but show channels shows channel 1 is not configured with a PID

the target port path of mpathadm show lu above for one disk matches
the wwpn for channel 0, 216000C0FF8A758B
sccli> show port-wwns
Ch Id WWPN
-------------------------
0 40 216000C0FF8A758B
1 42 226000C0FFAA758B
4 44 256000C0FFCA758B
5 46 266000C0FFEA758B
so host (hba) is seeing the luns provisioned through fc0 which mapped
to channel 0. but no other path
so could I just move the connection from fc1 to fc4 and expect
mpathadm to see two paths to the disks ?
will it hurt my raidz2 zpools which are already using block devices
with those long WWNs.
I am running sol 10 u3 with zpool version 15 (patched yesterday to get
to this level)

A: Because it messes up the order in which people normally read text.
Q: Why is top-posting such a bad thing?
