Title
pmmasterd: Cannot resolve hostname - Cannot run pmrun or pmksh - Request rejected by pmmasterd -
Description
When running pmrun or pmksh it fails with:
pmmasterd: 5033 Cannot resolve hostname
Request rejected by pmmasterd
-
Cause
In the case where this was issue was seen "pmhostlicense -sfh <hostname>" was showing that the client was bound to a different hostname. This was due to the hostname having been accidentally changed to "=" and because the "thishost_" setting was configured in the pm.settings file the masters were trying lookup an illegal hostname for the pmlocald connection.
-
Resolution
Renaming the host back to it's proper name, moving aside the cached registration info (/var/opt/quest/qpm4u/.qpm4u/.perfdata) and re-registering with pminfo -r resolved the issue.
