Cisco SAN Switch 

Firmware Update Procedure

SAN-OS contains 2 packages

 1) Kickstart – image (linux kernel files)

 2) System – image (commands and program files)

Latest firmware is 3.1 (3a)

Direct update to 3.1(3a) is allowed from 2.1 (2b), 2.1(2d), 3.0(1), 3.0(2a), 3.0(3), 3.1(2a), 3.1(3).

Now the firmware flash requires a compact flash card (CF).  This CF card is seen in the Cisco SAN-OS as bootflash card.

There is an issue, where if you insert a new firmware CF card, and the CF card checkup utility script finds a bad CF card. 

SAW document id: c00876068

The steps to perform firmware update are as follows

# copy running startup-config              

            This will save the running configuration as the startup configuration

# copy running ftp:// address>/

            This will save the running configuration to a FTP site

# show install all impact

            This will show the impact of “install all” command

# show install all failure-reason

            This will show the reason why “install all” command has failed in past.

# cd bootfalsh:

# dir

            This will show the contents of the bootflash (CF) card, and how much space is used and left in the card.

            This step is important because the kickstart image is ~ 20MB and system image is ~80 MB. Thus approx ~ 100 MB space in bootflash is required.

# copy ftp:// address>/ m9100-s1ek9-kickstart-mz.3.1.3a.bin    bootflash: m9100-s1ek9-kickstart-mz.3.1.3a.bin

            This will copy the file “m9100-s1ek9-kickstart-mz.3.1.3a.bin” from the ftp site to Bootflash

# copy ftp:// address>/m9100-s1ek9-mz.3.1.3a.bin   bootflash: m9100-s1ek9-mz.3.1.3a.bin

            This will copy the file “m9100-s1ek9-mz.3.1.3a.bin” from the ftp site to the Bootflash

# install all kickstart bootflash:m9100-s1ek9-kickstart-mz.3.1.3a.bin

# install all system bootflash:m9100-s1ek9-mz.3.1.3a.bin

            This will install the Kickstart and System image from the bootflash.

License Key installation

License key is a readable text file (.lic), and it has the serial number of the chassis in readable and encrypted format.

Chassis serial# is also called as host-id

# show license host-id

This show unique id for this host (chassis) for licensing

# show license usage

            Shows the status and usage of license.

 # show license brief

            This shows the list of license files

# copy bootflash:/// ftp:// address>/

            This will save the license file to a ftp location

# copy ftp:// address>/ bootflash:///

            This will copy the license file from the ftp site to the bootflash

# install license bootflash:///

            This will install the license file from the bootflash.

Once installed license, can check the activation of license, by “# show license usage”

# clear license

            This will clear the license

Eg:

# show license brief

Enterprise_PKG.lic

FabricManager_lic

# clear license Enterprise_PKG.lic

….

….

Clearing license …….done

License is bound to serial #, in case of switch or motherboard replacement new license key needs to be generated.
