Works on: Sun Solaris

Solaris disables disk cache by default, which has debatable advantages of data integrity, and definitive disadvantages in terms of I/O performance.

Here are the steps needed to enable the functionality:

# init 1
# format -e
format> cache
format> write_cache
format> display
format> enable
  (if disabled)

Happy computing.
