Yesterday, an Exadata storage server flashdisk entered the poor performance state.
This flashdisk os used by flashcache and has a griddisk which is a member of a normal redundancy diskgroup.
Identify the six steps you must perform to replace flashdisk.
Correct Answer: A,D,E,F,H,I
Explanation/Reference:
Note:
* The default way to deal with the Flash Storage is to use it completely as Flash Cache. You may think of Flash Cache as a prolongation of the Database Buffer Cache. It is populated automatically by the system with objects deemed useful to cache them.
* The second possibility to deal with the Flash Storage is to take a part of it for building ASM diskgroups upon. All files on these ASM diskgroups will then reside permanently on Flash Storage:
CellCLI> drop flashcache
Flash cache exa5cel01_FLASHCACHE successfully dropped
CellCLI> create flashcache all size=100g
Flash cache exa5cel01_FLASHCACHE successfully created
CellCLI> create griddisk all flashdisk prefix=flashdrive
