MSA 1000 - MPIO / Secure Path

Keld Johannessen_1 — Thu, 02 Jun 2005 03:05:41 GMT

Hi,

Is it possible to use MPIO on some servers and Secure Path on other servers all connected to the same MSA 1000?

Regards,

From MSA MPIO "Instalation Instructions":
"Prerequisites
â Basic multipathing solutions can not co-exist with any other multipathing solution, such as Secure Path or AutoPath.
If other failover methods are currently installed in your environment, HP recommends making no change, and to
continue using that method.
If you choose to migrate to the basic failover method, you must first un-install all other multipathing software from your
servers.
â The MSA must be installed in a supported environment, as detailed in the MSA Compatibility Guide and QuickSpecs."

Answer for your question - NO

regards,
A

I'm pretty sure this is a limitation -within- a single operating system instance.

On the same document:
"NO coexistence of basic multipathing and Secure Path on different servers in the same SAN".
If you want to mix such solutions, you must create separate SANs.

Hmmm. It looks like that document has managed to escape from me - where did you get it from?

This document (379632-0.PDF - HP StorageWorks Modular Smart Array 1000/1500 cs Basic Multipathing Installation Instructions) is a part of SP29009.exe driver/support pack (in \DOC folder after extracting).
