Managing the file system
This chapter describes how to manage the file system of your switch, including the storage media,
directories, and files.
Supported storage media
The switch supports the following storage media:
• Flash memory built in an MPU.
• USB disk connected to the USB port of an MPU.
• CF card inserted in the CF card slot of an MPU.
These storage media support FAT 16 and FAT 32 file systems.
The CF card and USB disk are hot-swappable.
An MPU has two USB ports, but only the upper one can be used.
H3C recommends that you use a Kingston 1-GB USB disk. The device does not support non-standard
USB devices, such as removable hard disks, USB hubs, MP3, and MP4.
Storage medium naming rules
The name of a storage medium follows the following rules:
• If a storage medium is the only storage medium of its type on the device, it is named by its type. For
example, if the device has only one Flash, the name of the Flash is flash.
• If there are multiple storage media of the same type on the switch, the physical device name of a
storage medium on the active MPU is the medium type name (for example, flash or cfa0), and the
physical device name of a storage medium on the standby MPU comprises the slot number and the
medium type (for example, slot1#flash or slot1#cfa0). If the switch is operating in IRF mode, the
physical device name of any other storage medium comprises the chassis number, slot number, and
the medium type (for example, chassis1#slot1#flash or chassis1#slot1#cfa0).
• If a storage medium is partitioned, the name of a partition comprises the physical device name and
the partition number. The sequence numbers of partitions are displayed in numbers such as 0, 1
and 2, for example cfa0.
File name formats
When you specify a file name, enter the file name in one of the formats shown in Table 15 . When you
specify a directory name, follow the rules for the drive and path arguments.
