Information About the Flash File System
The flash file system is a single flash device on which you can store files. It also provides several commands to help you manage software bundles and configuration files. The default flash file system on the device is named flash:.
As viewed from the active device, flash: refers to the local flash device, which is the device attached to the same device on which the file system is being viewed. In a device stack, each of the flash devices from the various stack members can be viewed from the active device. The names of these flash file systems include the corresponding device member numbers. For example, flash-3:, as viewed from the active device, refers to the same file system as does flash: on stack member 3. Use the show file systems privileged EXEC command to list all file systems, including the flash file systems in the device stack.
Only one user at a time can manage the software bundles and configuration files for a device stack .
