Re: RHEL 5.5 update & Device Mapper Multipath Enablement Kit
HP generally waits 3-6 months before they add support for the latest greatest Red Hat release.
You should if you need the kit wait for a version for 5.5 RHEL

Re: RHEL 5.5 update & Device Mapper Multipath Enablement Kit
HPDMmultipath-4.4.0 only seems to support up to RHEL 5.4. Have you tried editing the INSTALL File to force it to install?
Try editing Line 57 and copying it so you add:
@rhel54arr=("RHEL5", "release 5", "5.4", "RHEL5U5", "RHEL5.5", 0, 0);
Hey Bob -- are you the Bob Boyd from Pleasanton sir?

Re: RHEL 5.5 update & Device Mapper Multipath Enablement Kit
My RHEL 5.4 Systems after the latest "yum updates" now sport a "/etc/redhat-release" of:
Red Hat Enterprise Linux Server release 5.5 (Tikanga)
This normal?
I thought If you're installed distribution is say 5.4 -- no matter how you patch it, it stays at RHEL 5.4. Untrue then?

Re: RHEL 5.5 update & Device Mapper Multipath Enablement Kit
I have several servers that use Multipath, over EVA's and XP's, and I never have used HP's Multipath Enablement Kit. You don't "need" it, it just installs their own /etc/multipath.conf file.
You are better off learning about how that config file works, so you can better tune multipath to your local environment.

Re: RHEL 5.5 update & Device Mapper Multipath Enablement Kit
Untrue and dangerous pronouncement.
The HPDM kit also installs one or two /sbin binaries that are refeenced in the multipath.conf file.

Re: RHEL 5.5 update & Device Mapper Multipath Enablement Kit
HP DM Enablement kit includes a "patched" version of scsi_id, which is NOT installed (Look at the installer) for RHEL 5.4 and above, hence my comment.

Re: RHEL 5.5 update & Device Mapper Multipath Enablement Kit
I would not run yum update on systems until the HP PSP releases are there to support it.
I have worked with multi-path on RHEL 4 and 5, native and find it confusing, difficult to deal with and less robust than EMC tools. I don't like how EMC tools install and work with OS updates though.
Sorry about the yum update surprise above, but if you look at the output and don't do yum -y update and instead do yum update, you will get a list of updates a yes no choice and the chance to back out on a major upgrade.
RH has provided a major release update option for some time, the language is confusing in the text based yum. There is no Major version update, e.g. 5.x to 6.x that works with yum.
You can build a repository or stick in new media and boot/update the box, but that in my experience is a really good way to brick the box.
