Invoking OPatch

I use Sun Storage Flash Array and mount it.

$ mount -t vfat -o noauto,users,rw,umask=000 /dev/sdb1 /u01/app/flash_cache/ $ df
/dev/sdb1 23G 16K 23G 1% /u01/app/flash_cache

But I found error:
ORA-00439: feature not enabled: Server Flash Cache ORA-01078: failure in processing system parameters

*.db_flash_cache_file='/u01/app/flash_cache/file01.dbf' *.db_flash_cache_size=10G

What I should to do with Operating System or Disk?
