Managing HP Serviceguard A.11.20.00 for Linux, June 2012

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.

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