Using the File System Chapter 1 CLI Overview Send documentation comments to [email protected] Initializing bootflash: When a switch is shipped, the init system command is already performed and you do not need to issue it again. Initializing the switch resets the entire internal disk and erases all data in the bootflash: partition. The internal disk is composed of several file systems with bootflash: being one of them. All files in bootflash: are erased and you must download the system and kickstart images again. After issuing an init system command, you don't have to format the bootflash: again since bootflash: is automatically formatted. Note The init system command also installs a new loader from the existing (running) kickstart image. You can access this command from the switch(boot)# prompt. If bootflash: is found corrupted during a boot sequence, you will see the following message: ERROR:bootflash: has unrecoverable error; please do "format bootflash:" Use the format bootflash: command to only format the bootflash: file system. You can issue the format bootflash: command from either the switch# or the switch(boot)# prompts. If you issue the format bootflash: command, you must download the kickstart and system images again. Formatting Slot0: Be sure to format an external CompactFlash device before using it to save files or images. You can verify if the external CompactFlash device is formatted by inserting it into slot0: and issuing the dir slot0: command. • If the external CompactFlash device is already formatted, you can see file system usage information (along with any existing files). • If the external CompactFlash device is unformatted (corrupted), you will see the following message: Device unavailable In this case, you need to format the CompactFlash device using the format slot0: command. Note The slot0: file system cannot be accessed from the standby the loader> prompt or the switch(boot)# prompt, if the disk is inserted after booting the switch. Caution The Cisco MDS SAN-OS software only supports Cisco-certified CompactFlash devices that are formatted using Cisco MDS switches. Using uncertified CompactFlash devices may result in unpredictable consequences; formatting CompactFlash devices using other platforms may result in errors.
