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.
• 2—abnormal exit, also known as 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.
The package is allowed to run on an alternate node.
• 3—abnormal exit. The package did not halt normally and will be placed in the halt_aborted
state (page 266). The package switching is disabled and it will not failover to other nodes.
• 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

for failover packages.
