Error description

  • SCENARIO:
    CAA cluster running:
    - bos.cluster.rte 6.1.9.1

    - large amount of EMC disks (hdiskpower)
    
    PROBLEM:
    - the add operation a new node to an existing cluster may
    timeout on the node that is issuing the chcluster and on
    the node that is being added, the syslog.caa will show
    lots of the following like in a looping:

Local fix

  • N/A
    

Problem summary

  • CAA operations (mkcluster/chcluster) that register 3rd party
    disks may time out if there are a large number of disks on the
    system.
    

Problem conclusion

  • Provided an option to clusterconf that allows 3rd party disk
    registration prior to running CAA command.
    

Temporary fix
