8.6.3 Failover Operations for Search Servers

When failovers occur, the following messages are output to the event log or the system log (syslog) on the director server.

shn01903i: Searcher connection was broken. (192.168.10.1,33501) (director) [shund1] Shunsaku System Name=shunsaku
shn01904i: Switching to alternative searcher. (director) [shund1] Shunsaku System Name=shunsaku
shn01110i: Connected to searcher. (192.168.10.20,33501) (director) [shund1] Shunsaku System Name=shunsaku

To return both the failed searcher and the alternative searcher operating as a result of the failover back to their original configuration, after the failed searcher has been restored perform the following procedure.

1. Start the restored searcher by executing the shunsysstart command on the server where the searcher is located.

   shunsysstart  -n  Shunsaku system name

   When the searcher is started, the search data on the alternative searcher is automatically sent back to the restored searcher.

   Once the search data has been resent, the alternative searcher that has been operating enters an alternative standby state to prepare for other searcher failures.

   The following operations cannot be executed while search data is being automatically resent from the alternative searcher:

   • Update operations from applications
   • shundclear command
   • shundresend command
   • shundcds command
   • shundimport command
   • shundexport command
   • shundbackup command
   • shundrecover command
   • shunsysstop command
   • shunsyscfgedit command

This restores the system to its original configuration and restarts failover operations.
