Recreate cell disk xml files, in case of duplicate,incorrect entries reported by MS proces

Exadata Griddisk is giving issue after exadata upgrade 12.1.2.2.0.150917 on cell 06.

CellCLI> list griddisk

CELL-04633: PD-CD mapping has changed. Cell disk CD_09_x2ksc30cel06_duplicate_name (b76e17c2-385e-4fdd-8fb2-e88881ed5538)
used to be on physical disk null and LUN null, but now is on physical disk 20:9 (EXNDHX) and LUN 0_9.

CellCLI> list celldisk

CELL-04633: PD-CD mapping has changed. Cell disk CD_09_x2ksc30cel06_duplicate_name (b76e17c2-385e-4fdd-8fb2-e88881ed5538)
used to be on physical disk null and LUN null, but now is on physical disk 20:9 (EXNDHX) and LUN 0_9.

The problem is a logical mismatch that is pushed into the file cell_disk_config.xml.

Solution
=========

Recreate cell_disk_config.xml file.

1.1 Stop services on the cell. Validate they services can be stopped
cellcli -e list griddisk atributes asmdeactivationoutcome
cellcli -e alter cell shutdown services all
1.2 take a backup of the files moving them to a different location.
# cd $OSSCONF
# mkdir origfiles
# mv cell_disk_config.xml* origfiles
# ls -l origfiles/*
There is up to 3 files, one master and two copies.
Example:
ls -l $OSSCONF/cell_disk_config.xml*
-rw-r–r– 1 celladmin root 160120 Feb 13 14:01 /opt/oracle/cell11.2.3.3.0_LINUX.X64_131014.1/cellsrv/deploy/config/cell_disk_config.xml
-rw-r—– 1 celladmin root 160120 Feb 13 14:01 /opt/oracle/cell11.2.3.3.0_LINUX.X64_131014.1/cellsrv/deploy/config/cell_disk_config.xml_
-rw-r–r– 1 root celladmin 160120 Feb 13 17:26 /opt/oracle/cell11.2.3.3.0_LINUX.X64_131014.1/cellsrv/deploy/config/cell_disk_config.xml__
2. Restart the services on the cell
# cellcli -e alter cell startup services all

Issue fixed after re-creating xml files as above.
