- Synopsis: Modifications to revert resources, vnodes and hooks settings for Crayhave additional steps of deleting and creating nodes back, for retaining Cray specific resources.
- Standing of the interface : modified interface
- Detailsresources and vnodes
- As part of reverting resources, the PBS_HOME/server_priv/resourcedef file is removed.
- If on a Cray or Cray ALPS simulator , then recreate the out-of-box Cray-specific custom resources and vnodes,
- Checking that $alps_client and its value exists in PBS_HOME/mom_priv/config, and if so:
- delete all the vnodes: qmgr -c "delete node @default"
- add back the MoMs: qmgr -c "create n <MoM hostname>"
- check until such time that the MoM node has actually been added and the node state is free
- if successful, then
- the resourcedef file and the vnodes would have reverted to the out-of-box Cray configuration.
- If there is an error during one of the following:
- checking if $alps_client is properly configured
- deleting all vnodes
- adding MoMs
including the ones PBS creates from reading the ALPS inventory, by:- As part of reverting hooks, all hooks, except built-in hooks, are disabled.
- copying PBS_EXEC/lib/python/altair/pbs_hooks/PBS_translate_mpp.HK to PBS_HOME/server_priv/hooks/PBS_translate_mpp.HK
- if there is an error, then raise an exception
then set enabled=true in PBS_HOME/server_priv/hooks/PBS_translate_mpp.HKif there is an error, then raise an exception- then perform below:
- Delete all nodes and create them back.
If on a Cray or Cray ALPS simulator, then enable the PBS_translate_mpp hook by:
