IJ29210: MMVDISK RECOVERYGROUP CREATE FAILURE

APAR status

• Closed as program error.

Error description

• Running the mmvdisk rg create could assign a disk name
  that already exists resulting in error Example:
  
  # mmvdisk recoverygroup create --recovery-group rg1,rg2
  --node-class nc_1 --match 100
  ......
  mmvdisk: (mmcrvdisk) Disk name RG001LOGTIP is already
  registered for use by GPFS.
  mmvdisk: (mmcrvdisk) Error found while processing stanza
  ......
  
  Reported in:
  Spectrum Scale 5.0.4.2
  

Local fix

• There is a workaround which needs to be done under the
  guidance of IBM support.
  

Problem summary

• mmvdisk recovery group fails when creating log
  vdisks when creating a new recovery group in a
  cluster with preexisting recovery groups. An error
  message  "Disk XXX is already registered for use
  by GPFS" will appear on the command console,
  and the recovery group creation will fail.
  Once the problem condition is hit, IBM support must
  be contacted to correct the conflicting cluster information.
  

Problem conclusion

• Benefits of the solution:
  Recovery group creation will succeed.
  
  Work Around:
  Avoid using the "--servers" option in mmchrecoverygroup
  or the "--primary" and "--backup" options in mmvdisk
  recovery group change to invoke planned temporary
  recovery group reassignment for maintenance operations.
  Instead, use the "--active" option
  in mmvdisk or mmchrecoverygroup
  to specify temporary recovery group reassignment.
  
  
  Problem trigger:
  Users who have used mmchrecoverygroup --servers or
  mmvdisk recoverygroup to change --primary --backup on a
  preexisting recovery groups in a cluster may be affected
  when adding a new recovery group to that cluster.
