Basic Operation Guide 2013/06

NOTE: This step is necessary because HP switches do not support roll back (going from a
newer software version to an older software version) without the ability to copy a backup
config file onto the device.
4. Backup your current running image (primary) to the secondary image.
Switch1# copy flash flash secondary
Switch1# show flash
Image Size(Bytes) Date Version
------ ----------- ------- -------
Primary Image : 9839140 11/06/09 K.14.47
Secondary Image : 9839140 11/06/09 K.14.47
Boot Rom Version: K.12.20
Default Boot : Primary
5. Set your secondary image to boot with Config2.
Switch1# startup-default secondary config config2
Switch1# show config files
Configuration files:
id | act pri sec | name
---+-------------+-----------------------------
1 | * * | config1
2 | * | config2
3 | |
NOTE: Step 5 will enable you to revert from K.15.01.xxxx to your previous image with your
previous configuration just by invoking the command boot system flash secondary.
6. Download the new primary image.
Switch1# copy tftp flash 192.168.1.60
K_15_10_0001.swi primary
The Primary OS Image will be deleted, continue [y/n]?
At the prompt, enter ‘y’ for yes, and the new image will be downloaded and written to the
File system. Once tftp download has been completed you will see the following message:
Validating and Writing System Software to the
Filesystem ...
7. Verify that your images and configuration are set correctly. For example, if you updated from
K.14.47 to K.15.01.0031, you should see the following outputs from the switch show
commands:
Switch1# show version
Image stamp: /sw/code/build/btm(t4a)
