Re: DP8.1 Ipc invalid hostname or ip address

In the Error message, this is the key thing to look at

[Critical] From: BDA-NET@client3.domain.com "client3.domain.com [/CONFIGURATION]"  Time: 6/2/2014 12:25:02 AM  Cannot connect to Media Agent on system cellserver1.domain.com, port 56324 (IPC Invalid Hostname or IP Address) => aborting

For some reason, this p[ort is being blocked.  This has all the signs of trying to backup through a firewall.  After initial connection is made between teh Cell manager, Disk Agent and Media Agent using port 5555, then DP uses Dynamic Port Addressing to use whatever port is available, in ths case port 56324 was chosen

You have to create a firewall rule on the disk agent to allow a range of ports to be used for the backup, then you have to edit the file

Disk Agent (Linux)

   /opt/omni/.omnirc

Media Agent (Windows 2008)

   Program Data -> Omniback -> omnirc

and add the line

OB2PORTRANGE=[start]-[finish]

where "[start]-[finish]" represents the range of ports set by the firewall rule, so for example

OB2PORTRANGE=2000-2030

After saving the file, on Windows systems, DP INET service must be stopped and started

This must be done on BOTH the disk Agent and Media Agent

In the GUI, if you click on Help -> Help topics, and enter OB2PORTRANGE is the search string, there will be much more extensive discussions on this topic.  Also, if the DP 5.5 Admin Guide (the last version for which the Admin Guide was published)
