Can some explain me why i am getting UNKNOWN
Pseudo name=emcpowerd
Symmetrix ID=000xxxxxxxx
Logical device ID=0A3B
state=alive; policy=SymmOpt; priority=0; queued-IOs=1;
==============================================================================
--------------- Host --------------- - Stor - -- I/O Path -- -- Stats ---
### HW Path I/O Paths Interf. Mode State Q-IOs Errors
==============================================================================
7 UNKNOWN unknown FA 7eA active alive 0 0
7 UNKNOWN unknown FA 8eA active alive 1 0
8 UNKNOWN unknown FA 10eA active alive 0 0
8 UNKNOWN unknown FA 9eA active alive 0 0
This is a VMAX device mounted on a RHEL host.
Any ideas as to why this is happening. The device is working perfectly. It is in production....
How can I rectify this issue and make powerpath show me the paths.
You might try Powerpath does not see HW path and I/O path It seems to be very similar system to yours.

sol 1:
can you please try with following command
powermt dev=so
powermt config
powermt display dev=all
powermt save
sol 2:
same thing happens with other paths or only on this path(0A3B).if same thing not happens with other path please create a new meta device and assign on the same FA port and check now ,is it same .if no please take backup from volume 0A3B and restore on new vol.
Sol 3:
if it doesn't work please check power path version and os version and patch.check with power path comparability matrix from powerlink.if possible Please schedule a reboot for this host but b4 take backup .

powermt config does not do it ? I have a seen that on a couple of my RHEL 6 boxes. During regular monthly patching window they would get rebooted and that paths would show up correctly.
