Good evening,

Thanks a lot for your help, we appreciate it a bunch. Heres basically a summary of what we have (sorry Im adding some extra history as well):

We have 2 Ibm Servers (Hag and Aki) that are running AIX Version 5. Each connect to a SAN device via 2 separate fiber paths. Hag seems to have problems running varyonvg for 3 of the 5 logical volumes, while Aki can varyonvg all of them without a problem. My goal is to get Hag to be able to varyonvg all of the 5 logical volumes. Here is the history:

- Initial Problem (Battery Replacement - Resolved!)
Initially, one of our software GUIs displayed that a battery needed to be replaced in the Fiber adapter on the SAN device. I shutdown the entire system and safely replaced the battery according to the manuals. Upon restarting the system, the LED was green for that device. Upon booting up the servers (Hag and Aki), I noticed...

- Second Problem (Fiber Controller Card Bad, Replaced - Resolved?)
The back of the Hag chassis, has a 2 PCI cards (Fiber Adapters). One of them was bad. I shutdown the machine and replaced the fiber card with a spare. Upon booting it up, the LEDs turned Green like the other Fiber card, so Im assuming that it is connected again. I also used the manual for replacing it (i.e. running `cfgmgr` after replacement). Upon mounting the varyonvg volume groups, I found the current problem...

The SAN has 2 controller cards (controller_A [dac0], controller_B [dac1]) that are used when trying to mount these partitions.

Hag can map ALL virtual partitions if they are mapped through only controller_A (controller_B is disabled). However upon enabling controller_B, some partitions are moved by ADT only controller_A's partitions can be mapped.

Smitty is a centralized administrative application for running all sorts scripts to turn on and off fiber (HBA) devices, hard disks, LVM, and so forth. Do you have any ideas on how I may be able to perform additional tests to switch the mapping? I want to run a command that allows me to test the connectivity to Hag's dac1 (Disk Array Controller).

Here are the outputs of some commands on Hag:
#lsdev -C | grep fcs
fcs0 Available 1j-08 FC Adapter
fcs1 Available 14-08 FC Adapter ***
*** This FC Adapter is the one associated with the fiber connection that was down. (I.e., when I ran this command before replacing the Fiber Adapter on Hag, it was "Defined" instead of "Available").

#lsdev -C | grep dac
dac0 Available 1j-08-01 1722-600 Disk Array Controller
dac1 Available 14-08-01 1722-600 Disk Array Controller

#lsdev -C | grep dar
dar0 Available 1722-600 (600) Disk Array Router

#fget_config -A
--dar0--
dac0 ACTIVE dac1 ACTIVE
hdisk2 dac0
hdisk3 dac0
hdisk4 dac0
--dar1--

*** However on Aki, the results are different since dac1 is used and load distributed (ADT)
#fget_config -A
--dar0--
dac0 ACTIVE dac1 ACTIVE
hdisk2 dac1
hdisk3 dac0
hdisk4 dac1
hdisk5 dac1
hdisk6 dac0
hdisk7 dac1

*** Here are all of the physical volumes:
#lspv #FROM HAG MACHINE (All available vg's are varied on and active).
hdisk0 xxxxxxxxxxxxxxxx rootvg active
hdisk1 xxxxxxxxxxxxxxxx db01vg active
hdisk2 xxxxxxxxxxxxxxxx vg00 active
hdisk3 xxxxxxxxxxxxxxxx vg02 active
hdisk4 xxxxxxxxxxxxxxxx vg03 active
hdisk5 xxxxxxxxxxxxxxxx vg05 active

#lspv #FROM AKI MACHINE
hdisk0 xxxxxxxxxxxxxxxx rootvg active
hdisk1 xxxxxxxxxxxxxxxx None
hdisk2 xxxxxxxxxxxxxxxx vg00
hdisk3 xxxxxxxxxxxxxxxx vg01
hdisk4 xxxxxxxxxxxxxxxx vg02
hdisk5 xxxxxxxxxxxxxxxx vg03
hdisk6 xxxxxxxxxxxxxxxx vg04
hdisk7 xxxxxxxxxxxxxxxx vg05

When I run `varyonvg` on haguroyama, it lets varyonvg: vg00, vg02, vg03. It will not allow me to varyonvg volumes: vg01 (hdisk3), vg04 (hdisk6), and vg05 (hdisk7).

This is all the information I have at the moment. So basically to sum it up:

1) I want fget_config on Hag to have the same hdisks(2-7) as Aki.
2) I want to be able to varyonvg and be load distributed on Hag.

Thank you very much for your help!
