HP Serviceguard manual Runscripttimeout, Haltscripttimeout

NOTE: If the package halt function fails with “exit 1”, Serviceguard does not halt the node, but sets no_restart for the package, which disables package switching (auto_run), thereby preventing the package from starting on any adoptive node.

Setting node_fail_fast_enabled to yes ensures that the package can fail over to another node even if the package cannot halt successfully. Be careful when using node_fail_fast_enabled, as it will cause all packages on the node to halt abruptly. For more information, see “Responses to Failures ” (page 88) and “Responses to Package and Service Failures ” (page 90).

For system multi-node packages, node_fail_fast_enabled must be set to yes.

run_script_timeout

The amount of time, in seconds, allowed for the package to start; or no_timeout. The default is no_timeout. The maximum is 4294.

If the package does not complete its startup in the time specified by run_script_timeout, Serviceguard will terminate it and prevent it from switching to another node. In this case, if node_fail_fast_enabled is set to yes, the node will be halted (HP-UX system reset).

If no timeout is specified (no_timeout), Serviceguard will wait indefinitely for the package to start.

If a timeout occurs:

•Switching will be disabled.

•The current node will be disabled from running the package.

NOTE: VxVM disk groups are imported at package run time and exported at package halt time. If a package uses a large number of VxVM disk, the timeout value must be large enough to allow all of them to finish the import or export.

NOTE: If (no_timeout is specified, and the script hangs, or takes a very long time to complete, during the validation step (cmcheckconf (1m)), cmcheckconf will wait 20 minutes to allow the validation to complete before giving up.

halt_script_timeout

The amount of time, in seconds, allowed for the package to halt; or no_timeout. The default is no_timeout. The maximum is 4294.

If the package’s halt process does not complete in the time specified by halt_script_timeout, Serviceguard will terminate the package and prevent it from switching to another node. In this case, if node_fail_fast_enabled (page 235) is set to yes, the node will be halted (HP-UX system reset).

If a halt_script_timeout is specified, it should be greater than the sum of all the values set for service_halt_timeout (page 244) for this package.

If a timeout occurs:

•Switching will be disabled.

•The current node will be disabled from running the package.

If a halt-script timeout occurs, you may need to perform manual cleanup. See “Package Control Script Hangs or Failures” in Chapter 8. See also the note about VxVM under run_script_timeout (page 236).
