Write-back Flash Cache= WBFC
By default the flash cache mode in 11.2.3.2.0 is
write-through.
The following mentioned steps would change the mode from write
through to write-back.
All the changes would be executed using cellcli.
How to enable write-back flash cache (WBFC):
- We
will have to drop the existing Write-Through flash cache mode before doing any
changes.
For example:
CellCLI> drop flashcache
- Please
Shut down the CellSrv by using the below command:
CellCLI> alter cell shutdown services cellsrv
- Now
we are ready to change the flash cache mode to Write-Back using the below
command:
CellCLI> alter cell flashcacheMode = writeback
- Please
Start up CellSrv :
CellCLI> alter cell startup services cellsrv
- The
Flash cache needs a recreation for effect to take place. The below command
would do the change:
CellCLI> create flashcache all
