Try looking at this Symantec/netbackup tech note

http://www.symantec.com/business/support/index?page=content&id=TECH136791&actp=search&viewlocale=en_US&searchid=1311646427656

We find it helps to open the netbackup pbx and vnetd ports.

Subject: [Veritas-bu] Port 1556 on clients?

Recently, the DBAs have been upgrading to Oracle 11g, and we've upgraded to 
NetBackup 7.1.

And, then one of the RMANs has been failing....last week.

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on oem_sbt_backup channel at
07/22/2011 08:51:32
ORA-19506: failed to create sequential file, name="7vmi2h8g_1_1", parms=""
ORA-27028: skgfqcre: sbtbackup returned error
ORA-19511: Error received from media manager layer, error text:
VxBSAValidateFeatureId: Failed with error:
Server Status: cannot connect on socket

Did notice they were using 6.5 of the client, so we tried upgrading the client 
to 7.1.  Didn't help.

Our NBU admin is out this week at NetBackup training, and the DBAs are starting 
to panic running without RMAN backups.  They currently have like 575GB of ASM 
storage, and tried to ask for 500GB of additional temporary ASM storage to 
local disk backups....given poor track record on return of temporary 
storage....they aren't likely to get it.

Meanwhile, I happened to be poking around in the firewall logs...and see that 
our NBU media servers are trying (unsuccessfully) to connect to port 1556 on 
the host that the RMAN is failing on.

We have never opened this port for backups anywhere, and can't find any reason 
why we should.

Thoughts?

RMANs are working on other clients, and this port isn't open in the firewalls 
for those either (though all the clients seem to have something listening on 
the port.)
