Pre-execution and post-execution programs
HP 3PAR Cluster Extension can invoke pre-execution and post-execution programs prior to or after
a HP 3PAR Cluster Extension failover/failback function. These programs can be any executable,
and must be able to provide return codes to HP 3PAR Cluster Extension. If the programs add
significant execution time to the application service startup process, the timeout values for the
startup process must be adjusted in the cluster software.
HP 3PAR Cluster Extension transfers information as CLI arguments to the pre-execution and
post-execution programs. You must not specify CLI arguments. Pre-executables and post-executables
must be specified by full path in the PreExecScript and PostExecScript objects. If no
executable is specified (there is an empty value for the object), no preprocessing or postprocessing
is performed. If the object is not defined, then the argument value is empty.
The following arguments are transferred to the scripts in this order:
1. Resource name
2. DC A HP 3PAR storage system serial number
3. DC B HP 3PAR storage system serial number
4. DC A Remote Copy volume group
5. DC B Remote Copy volume group
6. DC A host (server) names
7. DC B host (server) names
8. Replication mode
9. Local replication role
10. Remote replication role
11. Remote copy link status
12. Failsafe policy
13. Remote Copy volume group status
