Information in this document applies to any platform.
Goal
Correct the host~Rs multipath.conf to add support for AX600 presented LUNs
Fix
Model: AX600
Release: 030215-014100
Update Details
Description:
This system was recently upgraded to an AX600, looking at the multipath.conf file for the one and only linux host it is missing the policy for AX600 LUNs so it the pathmanager tools have no idea how to implement correct pathing policies for the LUNs presented.
The multipath.conf included with APM 2.0.1 did not know about AX600 system types. Newer versions of APM include listings for the AX600.
Containment:
Correct the host~Rs multipath.conf to add support for AX600 presented LUNs
Solution: the following entry should be added to multipath.conf on all Linux hosts connecting to the axiom then restart the axiompmd services on the host to pickup the change.
