[Solved] how to Enable VxDMP & Disable MPIO?
Hello people.
I am new to AIX & dealing with VxDMP.
The server has AIX 7.1, storage is Hitachi. I have 4 paths from my server to the array. However, the vxdmp shows only single path. I went through some discussions & realized that it is because of MPIO.
Then,
I did following -
* Uninstalled Vx Stack
* Removed disks using rmdev -dl disk
* Installed the Object Data Manager (ODM) definitions for the devices on the host. (Hitachi)
* Reboot server
* Re-Install Vx
Still no avail! Only single path is seen.
Am I missing something?

We nailed it!
Some mistake on my part.
>> Installed the Object Data Manager (ODM) definitions for the devices on the host. (Hitachi)
Apparently, I had installed "MPIO ODM" instead of "non-MPIO ODM's"
Uninstalling the MPIO ODM & installing non-MPIO ODMs (followed by cfgmgr) solved the issue.

Equivalent to using padsp is starting an application with $LD_PRELOAD set to libpulsedsp.so OPTIONS
