Running import with force option is failing with following error:

CellCLI> import celldisk CD_11_dm01cel02 force

Received Error: CELL-02525: Unknown cell disk: CD_11_dm01cel02
Cell disks not imported: Celldisk: CD_11_dm01cel02

Solution

1. Drop the cell disk:

cellcli> drop celldisk <CelldiskName> force

2. Now create celldisk and griddisk manually using following note
