HBA's not communicating with DMX-3

[David P. Waters]

Okay, I have a good one!!

Env: I have a HP SuperDome (SD32A from 'model') directly connected to a DMX-3 through FC-AL. The SuperDome is divided up into 2 nPar each has 4 fibre connections to 8 FA ports on the DMX. The HBA's are A6795A, driver B.11.11.12. nPars are running 11.11

Issue: I can only see LUNS down one FA port on the DMX no matter which cable I use or which card out of the 8 I use........done only one FA port on the DMX. 'fcmsutil /dev/td#' on each of the hba's displays the following:

/opt/fcms/bin/fcmsutil /dev/td0

Each of the hba's displays the same. However, the 'fcmsutil /dev/td# get remote all' only works on the hba that is plugged into the good FA on the DMX. It display the following:

/opt/fcms/bin/fcmsutil /dev/td0 get remote all

Notice the "Target State". The other hba's return "No Device Found" when I run the same command on them.

##### NOTE #####
Here's the catch (pay attention): I can run any cable from any FA port on the DMX that is NOT visible to the above mentioned nPars to a totally different HP SuperDome (older model) HBA......LUNS are visible down the FA.

Any ideas? It seems as if the newer SuperDome is not allowing multiple hba logins to the DMX-3.

NOTE: HP and EMC are looking into the case.

Topology = PRIVATE_LOOP

Shouldn't that be FABRIC ?

[David P. Waters]

Not for a direct connect. A switched topology would show FABRIC.
