CREATE A CELL IN EXADATA STORAGE SERVER
A cell is a software which contains the exadata software in the storage server with CELLSRV, MS and RS processes to operate the exadata system.
During installation of exadata software in a virtual lab, the cell need to be created with the help of cellinit.ora file which contain the ipaddress of the host.
