Can MPIO and PowerPath exist on the same AIX server?
I wouldn't share the same HBA's between the two, just have PP on a
pair and MPIO on a different pair.

Actually, MPIO is alway present on AIX. You cannot remove it, even if
another multipathing software is installed.
So, the answer is: YES.

Hi,
Please refer to the EMC Host Connectivity Guide for IBM AIX at :
http://powerlink.emc.com/ > Support > Documentation/White Paper
Library > Host Connectivity/HBAs > Installation/Configuration

The following MPIO/ PowerPath combinations are possible:

â—† Symmetrix-MPIO + CLARiiON-PowerPath
All Symmetrix devices must be exclusively configured into MPIO and all
CLARiiON devices must be exclusively configured into PowerPath with
minimum version 3.0.4.2. No Symmetrix devices can be configured into
PowerPath. (i.e. devices under MPIO control can not also be configured
into PowerPath at this time).

â—† Symmetrix-PowerPath + IBM ESS-MPIO
Dedicated HBAs for Symmetrix devices configured into PowerPath and
dedicated HBAs for IBM ESS storage devices into MPIO.

◆ Symmetrix-MPIO + IBM ESS-MPIO — Dedicated HBAs for Symmetrix devices
configured into MPIO and dedicated HBAs for IBM ESS storage devices
into MPIO.

â—† Symmetrix-MPIO + IBM FAStT-RDAC
Dedicated HBAs for Symmetrix devices configured into MPIO and
dedicated HBAs for IBM FAStT storage devices into RDAC.

â—† CLARiiON-PowerPath + IBM ESS-MPIO
Dedicated HBAs for CLARiiON devices configured into PowerPath and
dedicated HBAs for IBM ESS storage arrays configured into MPIO.

â—† Symmetrix-MPIO + CLARiiON-PowerPath + IBM ESS-MPIO
Dedicated HBAs for Symmetrix devices configured into MPIO and
dedicated HBAs for the CLARiiON devices configured into PowerPath and
dedicated HBAs for IBM ESS storage arrays
configured into MPIO.

â—† Symmetrix-MPIO + FAStT-RDAC + IBM ESS-MPIO
Dedicated HBAs for Symmetrix devices configured into MPIO and
dedicated HBAs for the IBM FAStT storage devices configured into RDAC
and dedicated HBAs for IBM ESS storage
arrays configured into MPIO.


I hope, this answers your question ?

Best regards,

Swen

Thanks. I realize MPIO is present but the actual question is can I
use it on one set of HBA/LUN combinations and have PowerPath on a
different set of HBA/LUN combinations.
The other response was what I was looking for.
Thanks again!

powermt has an umanage parameter to tell powerpath to leave classes of
devices alone. So you should be able to unmanage the MPIO devices and
still use powerpath on the other ones.

Hi,
I suggest to consult the following documents, too:

1. EMC PowerPath for AIX, INSTALLATION AND ADMINISTRATION GUIDE,
chapter "Co-existence with third-party path management software" at
http://powerlink.emc.com > Support > Documentation/White Paper
Library.

2. EMC Support Matrix, cahpter 'Non EMC Storage - Mixed Storage
Environment':
http://www.emc.com/interoperability/...portMatrix.pdf
