RHEL5.3 multipath and EVA 5000

JJ.CHIOU — Wed, 29 Jul 2009 16:05:52 GMT

I have a newly installed RHEL 5.3 on a DL585G2 with two QLogic HBA (QLA2300). I have 1 drive presented to this server from an EVA 5000. I have installed hp-fc-enablement-2009-03-30 as well as HPDMmultipath-4.3.0. I have rebooted the server and multipathd is running, but multipathing is not working correctly. Below is the output of the multipath -ll command. Does anyone know why it show [failed][faulty] next to each path to the EVA? What additional steps do I need to configure RHEL5.3 for EVA storage? thanks alot

Shalom,

Since the server is relatively old, I would check the firmware bios and the HBA firmware for updates.

You may be encountering a problem with the hardware interfering with multi pathing.

RHEL 4 document that may work for 5.3

Deals with install, however the links inside deal with more topics.
