Internal bootflash:
All switches in the Cisco MDS 9000 Family have one internal bootflash: that resides in the supervisor
or switching module.You have access to two directories within the internal bootflash: file system.
• The volatile: directory which provides temporary storage, and is also the default. Files in temporary
storage (volatile:) are erased when the switch reboots.
• The bootflash (nonvolatile storage): directory which provides permanent storage. The files in
bootflash are preserved through reboots and power outages.
External CompactFlash (Slot0)
Cisco MDS 9500 Series directors contain an additional external CompactFlash called slot0:
The external CompactFlash, an optional device for MDS 9500 Series directors, can be used for storing
software images, logs, and core dumps.
Formatting Flash Disks and File Systems
By formatting a flash disk or a file system, you are essentially clearing out the contents of the disk or
the file system and restoring it to its factory-shipped state (see the
“About Flash Devices” section on
page 1-30 and “Using the File System” section on page 1-32 for additional information).
