Testing a CFlash card

Software Release 3.0.2
C613-03092-00 REV C
You can insert a card into the CompactFlash slot at any time; it takes about two
seconds to initialise. The following CLI message confirms that a card has been
inserted:
Info (1106257): Compact flash card inserted.
The following message confirms that the card is ready to use:
Info (1106268): Compact flash card initialisation successful.
The following message means that the CFlash card is not compatible with the
switch:
Info (3106300): Compact flash card initialisation
unsuccessful.
Important When data is being written to or read from the card, the CF LED on
the front panel of the switch is green. Do not remove the card when it is active
or you will corrupt the data. Wait until the LED is off before ejecting the card.
To display information about the basic state of a CompactFlash card, including
card size, file count, and serial number, insert the card and enter the command:
show cflash
To display cluster ranges on a card, insert the card and enter the command:
show cflash test
The following figure is an example of output from the show cflash test
command when no test is running.
Clusters available for testing
Ranges:
[42645--61944]
Number of free clusters
Number of ranges
Number of used clusters
To test a card, insert it in the CF slot and enter the command:
enable cflash test start=startnumber end=endnumber
where startnumber and endnumber are positive integers within a cluster range.
The end number must be higher than the start number. Cluster ranges are
displayed in the output of the show cflash test command.
The test software reads the file allocation table and displays a list of free
sectors. Sectors can be tested as single sectors or as a range. The test consists of
a write/read/verify cycle.
To stop the test, use the disable cflash test command. To display test results
while a test is in process, enter the show cflash test command.
