Preliminary Information for Purging and Flushing NVRAM Data

• The flush option flushes any outstanding writes from NVRAM to the disk drive.

• If you get an error while flushing data, you must purge the data. Purging data "throws away" any outstanding writes in NVRAM.

• Purging fast write data should be performed with caution, and only when a drive has failed, as it could result in the loss of data.

• If the NVRAM battery is low, missing, or has failed, the menus will be disabled, because the NVRAM is non-functional and data there would be lost.
