IV62909: CAA: CHCLUSTER TO ADD NODE MAY LOOP IF LARGE NUMBER OF EMC DISKS APPLIES TO AIX 7100-02

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• SCENARIO:
  CAA cluster running:
  - bos.cluster.rte 6.1.9.1
  - devices.common.IBM.storfwork.rte 6.1.9.0
  - 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
