EMC-symmetrix DMX series configuration issues.

Hi Admins,

My storage is EMC-Symmetrix DMX series and my ioscan -fnkC fc and powermt gives below output in HPUNIX 11.23 server.

ioscan -fnkC fc

Class I H/W Path Driver S/W State H/W Type Description
========================================================================
fc 0 0/3/1/0/4/0 fcd CLAIMED INTERFACE HP A9784-60002 PCI/PCI-X Fibre Channel FC/GigE Combo Adapter (FC Port 1)

fc 1 0/6/1/0/4/0 fcd CLAIMED INTERFACE HP A9784-60002 PCI/PCI-X Fibre Channel FC/GigE Combo Adapter (FC Port 1)
/dev/fcd1

powermt display dev=all

Symmetrix ID=000290300315
Logical device ID=0044
state=alive; policy=SymmOpt; priority=0; queued-IOs=0
==================================================================

8 0/3/1/0/4/0.1.0.0.0.1.0 c8t1d0 FA 16cA active alive 0 0

As am new in storage setup can any one explain me the symmetrix arichitectue with respct to my configuration. As I have two FC card but powermt shoes only one channel is configured. Is I have any risk on this?

Thanks in advance.

looks good to me. You have two HBAs in the system and each HBA is zoned to an FA port on DMX. FC 0 is zoned to FA 16C:A and FC 1 is zoned to 1C:A. PowerPath policy is set to SymmOpt which means the host will use both HBAs concurrently to send data to DMX device.
