Goal
Sun Storage 2500, 2500-M2, and 6000 Arrays used in Red Hat Enterprise Linux (RHEL) environments require multipathing software. Two different multipathing solutions are supported:
- RDAC/MPP, Redundant Dual Active Controller Multipath Proxy driver (provided by NetApp)
- DMMP, Device Mapper Multipath driver (Linux native driver)
This document presents the methods to determine which solution is installed and configured on your server.
DMMP and RDAC/MPP cannot co-exist on an RHEL host. Only one should be installed. DMMP is supported on firmware 07.77.xx and above, and only for these arrays:
- Sun Storage 2530-M2 Array
- Sun Storage 2540-M2 Array
- Sun Storage 6180 Array
- Sun Storage 6580 Array
- Sun Storage 6780 Array
