HP Serviceguard manual Normal and Abnormal Exits from the Halt Script

NOTE: This diagram applies specifically to legacy packages. Differences for modular scripts are called out above.

Normal and Abnormal Exits from the Halt Script

The package’s ability to move to other nodes is affected by the exit conditions on leaving the halt script. The following are the possible exit codes:

•0—normal exit. The package halted normally, so all services are down on this node.

•1—abnormal exit, also known as no_restart exit. The package did not halt normally. Services are killed, and the package is disabled globally. It is not disabled on the current node, however.

•Timeout—Another type of exit occurs when the halt_script_timeout is exceeded. In this scenario, the package is killed and disabled globally. It is not disabled on the current node, however. The package script may not have been able to clean up some of its resources such as LVM volume groups, VxVM disk groups or package mount points, so before attempting to start up the package on any node, be sure to check whether any resources for the package need to be cleaned up

Package Control Script Error and Exit Conditions

Table 4 shows the possible combinations of error condition, failfast setting and package movement for failover packages.
