Managing file systems
Overview
File systems
The device supports the flash memory, CF card, and USB disk.
•
The flash memory has one file system.
•
The CF card and USB disk can be partitioned. An unpartitioned storage medium has one file
system. A partitioned storage medium has one file system on each partition.
File system naming conventions
The name of the file system on a flash memory has the following parts:
•
File system location. For more information, see "
•
Storage medium type
flash
.
•
Colon (:).
The name of a file system on a CF card or USB disk has the following parts:
•
File system location. For more information, see "
•
Storage medium type,
cf
or
usb
.
•
Sequence number, a lower-case English letter such as a, b, or c.
•
Partition number, a digit that starts at 0 and increments by 1. If the CF card or USB disk is not
partitioned, the system determines that the CF card or USB disk has one partition.
•
Colon (:).
For example, the file system on the first partition of the first USB disk is named
usba0:
.
IMPORTANT:
File system names are case sensitive and must be entered in lower case.
File system location
(In standalone mode.) To identify a file system on the active MPU, you do not need to specify the file
system location. To identify a file system on the standby MPU, you must specify the file system
location in the
slotn#
format. The
n
argument represents the slot number of a card. For example, the
location is
slot16#
for a file system that resides on the card in slot 16.
(In IRF mode.) To identify a file system on the global active MPU, you do not need to specify the file
system location. To identify a file system on a global standby MPU, you must specify the file system
location in the
chassism#slotn#
format. The
m
argument represents the member ID of the IRF
member device. The
n
argument represents the slot number of the MPU. For example, the location is
chassis2#slot16#
for a file system that resides on the MPU in slot 16 of member device 2.
Default file system
You are working with the default file system by default after you log in. To specify a file or directory on
the default file system, you do not need to specify the file system name. For example, you do not
need to specify any location information if you want to save the running configuration to the root
directory of the default file system.
To change the default file system, use the BootWare menu. For more information, see the software
release notes.
