status 213 - no storage units available
has anyone come across this issue?

Master server E10K - Solaris 8
Media server: Netra - Solaris 8 (temporary license key)
Netbackup 3.4 + Patch 6 + SSO

A new media server fails with error code 213.
tried the usual stuff:

* Restarted both servers (master & media) to force them to reread STU
* Verified bp.conf files (server entries)
* Patch level is the same
* Verified Storage Units: (density etc. - looks OK)
* Verified services (all services are there)
* bpclntcmd -pn (returns the right names / addresses)
* can see tape drives on O/S level (mt command)
* Setup logs for vmd (debug/daemon) ; bpcd; bpsched and inreased VERBOSE
level - no errors are logged apart of 213- no storage units available

I ran out of ideas.
