While preparing for a Parallels Operations Automation (POA) upgrade, it is essential to verify the POA slave node's availability from within the POA internal intercommunication system (CORBA).
Note: this utility has been incorporated into
Use the script from the attached archive to verify the POA slave node's availability:
~# ./ping_slave.sh pinging host 1: SUCCESS . . . pinging host 13: SUCCESS pinging host 14: SUCCESS pinging host 15: FAILED pinging host 16: FAILED pinging host 17: FAILED pinging host 18: FAILED pinging host 19: SUCCESS pinging host 20: FAILED
The hosts' initial lookup is done through the database so, in some cases, it will be necessary to adjust the script accordingly.
This script also produces a debug output, which is stored in the file
ping.res (in the current directory). This output can be helpful during further troubleshooting.
For example, the hostnames of unavailable hosts can be obtained quickly through:
~# grep ERROR ping.res
Parallels KB article "How to fix unmanageable POA-managed server" also can be helpful during troubleshooting.
