I spend hours today troubleshooting and found a solution. I wanted to share this for anyone else that may get snagged on this.
Scenario:
DP v8.1
Windows Cell Mananager
Linu base Installation server
HPUX 11iv3 agent with DA and MA
I was running into issues upgrading the HPUX agent from DP v7.01 to v8.1 due to continuous time-out errors
-Pushing the agent though the IS server would install the software but fail during the import
-manual install of the agent worked with no issues but could not import into the CM
-/var/opt/omni/log/inet.log would report success for all steps except at the end a time-out during the import
-I manually added the hpux server info into the cell_info file on the CM but when attempting to configure a test backup of the HPUX client, it just sat and spun during the filesystem browse.
During the sit and spin session I looked into the /var/opt/omni/log/debug.log file and found a number of ipw_getaddrinfo(.....) Network performance warning messages.
found this post http://h30507.www3.hp.com/t5/Technical-Support-Services-Blog/DPTIPS-Data-Protector-IPv6-and-the-Unintended-Consequence/ba-p/109643
the cause... looks like DP8.1 wants to do ipv6. My server has no ipv6 entries in the nssswitch.conf file so it was going after DNS for ipv6, there is no ipv6 in my environment( nor most other people's for that matter), so it was timing out..
the solution... (read the blog entry), add an "ipnodes" entry to the nsswitch.conf file and problem solved ( after 3 hours of troubleshooting ).
Hope this helps someone else if they run into the same issue.
Cheers
