Chapter 3 Installing the Router
Using Flash Memory Cards in the RP
To remove deleted files from a Flash memory directory permanently, but leave
undeleted files intact, enter the squeeze device-name command at the privileged
EXEC mode prompt on the system console, where device-name can be slot0:,
slot1:, or bootflash:. The squeeze command permanently removes deleted files
and makes all other undeleted files contiguous, thus conserving storage space.
To prevent loss of data due to sudden power loss, the squeezed data is temporarily
saved to another Flash memory area reserved specifically for system use.
An example of the squeeze command follows.
Router# squeeze slot0:
All deleted files will be removed, Continue? [confirm]y
Squeeze operation may take a while, Continue? [confirm]y
Squeeze of slot0 complete
Router#
ebESZ
In the preceding example command display, the characters in the final line
(ebESZ) represent the Flash memory operations performed during the execution
of the squeeze command.
Table 3-14 describes these indicators.
During the squeeze operation, the system maintains a log identifying which of the
squeeze functions has been accomplished, so that the system can return to the
proper place and continue the operation in the event of a power failure.
