APAR status

  • Closed as program error.

Error description

  • Async release of resources is done by ROHA as
    background process. It can hang when running a command
    and will fail only after a timeout. If a node is
    rebooted when clasyncroha hung, rg acquire after reboot
    gets into config_too_long like below :
     clmanageroha: ERROR: Waited for 360 sec on
      asynchronous release of resources, but still in
      progress. Could not proceed, try again later on.
    
    RG acquire completes after config_timeout of 360 seconds.
    

Local fix

  • Clear the ODM after reboot of node when clasyncroha hung
    :
    print -- "HACMPdynresop:\\nvalue=\"\"" |
    ODMDIR=/etc/es/objrepos odmchange -o HACMPdynresop
    -q "key=REL_APPS"
    

Problem summary

  • If a node is rebooted when clasync roha is going on, post reboot
     rg acquire gets into config_too_long like below : clmanageroha:
     ERROR: Waited for 360 sec on asynchronous release of resources,
     but still in progress. Could not proceed, try again later on.
    RG acquire completes after config_timeout of 360 seconds.
    

Problem conclusion

  • Modified code to reset the REL_APPS value during node up
    

Temporary fix
