Chapter 1 Maintaining Your WAAS System
Backing Up and Restoring your WAAS System
An installation that contains only the WAAS flash memory-based software, without the
corresponding disk-based software, boots and operates in a limited mode, allowing for further disk
configuration before completing a full installation.
The .sysimg component is provided for recovery purposes and allows for repair of flash memory
only without modifying the disk contents.
Note The system image used depends on your device. For all WAVE and WAE-674/7341/7371 devices
(64-bit platforms), use the 64-bit system image (with “x86_64” in its name). For all other
devices, use the 32-bit system image named without this designator.
An NPE image is provided that has the disk encryption feature disabled for use in countries
where disk encryption is not permitted.
If you have a WAVE appliance that requires a USB flash drive for software recovery, your USB flash
drive must contain both of the needed software images in the form of an ISO archive file that you copy
to the flash drive. (See the “Preparing the USB Flash Drive” section on page 1-13).
These options are available from the software recovery installer menu:
• Option 1: Configure Network—If the .bin image you need to install is located on the network instead
of the CD-ROM or USB flash drive (which may be the case when an older CD-ROM or USB image
is used to install new software), then you must choose this option to configure the network before
attempting to install the .bin image.
This option is performed automatically if you install a .sysimg file from the network.
• Option 2: Manufacture Flash—This option verifies the flash memory and, if invalid, automatically
reformats it to contain a Cisco standard layout. If reformatting is required, a new cookie is installed
automatically.
This option is performed automatically as part of a .bin or .sysimg installation.
• Option 3: Install Flash Cookie—This option generates a hardware-specific platform cookie and
installs it in flash memory. You need to use this option only if there has been a change in the
hardware components, such as replacing the motherboard, or if you moved a flash memory card
between systems.
This option is performed automatically during the flash manufacturing process, if needed, as part of
a .bin or .sysimg installation.
• Option 4: Install Flash Image from Network and Option 5: Install Flash Image from
USB/CD-ROM —These options allow installation of the flash memory .sysimg only and do not
modify disk contents. They may be used when a new chassis has been provided and populated with
the customer’s old disks that need to be preserved.
These options automatically perform flash verification and hardware cookie installation, if required.
When installing from the network, you are prompted to configure the network if you have not
already done so.
• Option 6: Install Flash Image from Disk—This option is reserved for future expansion and is not
available.
• Option 7: Recreate RAID device—This option applies only to WAE-674, WAE-7341, WAE-7371,
WAVE-7541, WAVE-7571, and WAVE-8541 devices and recreates the RAID array.
• Option 8: Wipe Out Disks and Install .bin Image—This option provides the preferred procedure for
installing the WAAS software.
