PowerPath software is "rented" (with a subscription price that is far from small) from EMC.

EMC Customer Support is somewhat well regarded...

Have you considered their support number? 1 (888) 544 4445

Should be relatively straghtforward - you need to check kernel revisions. You might find the simplest approach is to de-install 5.1 and install 5.5 cleanly. IIRC, the biggest change is the move to a centralised licensing server.

Latest for Linux is 5.7 SP01 P02 - I'd recommend going to the current version.

EMC is exceptionally careful with their drivers -- matching them specifically to kernel releases.

To maintain your EMC support and warranty contracts, you must (repeat: MUST) ensure that your server is running the supported Linux kernel revision for the version of PowerPath you want to upgrade to.

Mis-matching your kernel and PowerPath drivers will void your support with EMC... and while you may not have any trouble with mixing PowerPath and a newer (or even slightly older) kernel release, why risk it?

IF IT WERE ME -- and I was taking the opportunity to reboot & upgrade a server (which I do RARELY ... if it works, DON'T FIX IT!... then I would go as far forward as I could.

Sorry - that's just wrong. If there are version mismatches, support will tell you that you need to fix it and *then* they can look at the problem if it still exists. The only time I've ever seen an issue was with Oracle Non-Stop Linux 5.0 - because changing the drivers meant support issues with Oracle. Bit of a problem when only one version of PowerPath is supported and it's got  a bug...

Check the PP release notes, especially the Known Issues section. Also check e-Lab Navigator from powerlink.emc.com. But PP 5.6 should be fine.
