Goal

After disk replacement the cell disk name is appears similar to "%_duplicate_%" and the griddisk status is showing "importRequired".

In the following example disk CD_11_dm01cel02 has been replaced.

List celldisk shows following status:

name:               CD_11_dm01cel02_duplicate_name

List griddisk status shows following status:

SYSTEMDG_CD_11_dm01cel02        importRequired

DATA_CD_11_dm01cel02            importRequired

List physicaldisk output is showing status normal:

Running import with force option is failing with following error:

CellCLI> import celldisk CD_11_dm01cel02 force



CELL-04560: Cannot complete import of cell disk CD_11_dm01cel02.  

Received Error: CELL-02525: Unknown cell disk: CD_11_dm01cel02

Cell disks not imported: Celldisk: CD_11_dm01cel02

Fix

1. Drop the cell disk:

cellcli> drop celldisk <CelldiskName> force

2. Now create celldisk and griddisk manually using following note
