"Unlic" path

Hi all,
I've inserted a license key in my EMC powerpath (PowerPath (c) Version 4.5.1 (build 1))
It seems all right because powerpath says:
# powermt check_registration

Key xxxx-xxxx-xxxx-xxxx
Product: PowerPath
Capabilities: All

but when I run "display" command I find some "unlic" path as following:

# powermt display
Symmetrix logical device count=0
CLARiiON logical device count=14

What is happening?

Its because the "Unlic"ensed ones are set to a policy of "BasicFailover" instead of "CLAROpt".

BasicFailover is a "give-away" option which requires no license key, to allow non-disruptive upgrades to be performed on the Clariion. It doesn't perform any load-balancing, and only allows two paths to be configured (hence why your other two show as "Unlic").

Its probably happened because storage was configured before the PP license key was installed.

To resolve this:

# powermt set policy=co class=clariion dev=all
# powermt save

Best Regards,
Marc

Does anyone out here have a condensed list of the PowerPath commands and their use? Rather than having to look it up in the doc set, it would be handy to have on hand. Just a thought....

My Powerpath top list

- check powerpath license - powermt check_registration
- check devices : powermt display dev=all | more
- check number of dead paths : powermt display paths
- remove dead paths : powermt check (useful to see if a single HBA or port is acting funny)
- scan paths : powermt config
- save config : powermt save (usually after powermt config)
- check version - powermt version

PowerPath Quick Reference

It's only a few pages and conatains the full list of commands and usage
