unconfigure RDAC to install SDDPCM

[alexia32]

Hello

SDDPCM is now supported on aix 5.3TL9 for DS4K.
I would like to know how to unconfigure RDAC to be able to use sddpcm.

I tested a preview installation of sddpcm (via smitty) and didn;t complain that I needed to deinstall something first.

I didn't yet install sddpcm as I need to know what needs to be done first on the RDAC disks ?

Do you know if there is any document saying how to unconfigure RDAC?

My RDAC knowledges is really limited as I always use SDDPCM...

Thanks in advance
Al.

Hi
maybe is this helpfull? I didn't use it myself though.

Check the AIX systems driver support and state by running the following command:
# ‘manage_disk_drivers’
This will display the DS4000 devices that are supported by MPIO as well as RDAC and if they are
currently configured for MPIO or RDAC enablement.

# manage_disk_drivers
1: DS4300: currently RDAC/fcparray; supported: RDAC/fcparray, MPIO
2: DS4500: currently RDAC/fcparray; supported: RDAC/fcparray, MPIO
3: DS4700/DS4200: currently RDAC/fcparray; supported: RDAC/fcparray, MPIO
4: DS4800: currently RDAC/fcparray; supported: RDAC/fcparray, MPIO

7) From “example a”, we know that hdisk2 is a DS4500 and from “example b” we know that
the DS4500 is currently enabled for RDAC/fcparray. To change which driver is managing
the DS4000, do the following commands in order-
# manage_disk_drivers – c 3
The “3” represents the DS4700 as indicated in the ‘manage_disk_drivers’ command output. If you
had a DS4800 attached you would use a “4” in place of the “3” and so on.
