Switch Memory and Configuration
Using Primary and Secondary Flash Image Options

Verify that there is a valid flash image in the secondary flash location. The
following figure indicates that an OS image is present in secondary flash.
(If you are unsure whether the image is secondary flash is valid, try
booting from it before you proceed, by using

boot system flash secondary.)

Secondary Flash

Execute the copy command as follows:

Erasing the Contents of Primary or Secondary Flash.

This command

deletes the OS image file from the specified flash location.

Before using this command in one flash image location (primary or second-
ary), ensure that you have a valid OS file in the other flash image location
(secondary or primary). If the switch has only one flash image loaded (in either
primary or secondary flash) and you erase that image, then the switch does
not have an OS stored in flash. In this case, if you do not reboot or power cycle
the switch, you can recover by using xmodem or tftp to download another OS.

Syntax:

erase flash < primary | secondary >

For example, to erase the OS in primary flash, do the following:

First verify that a usable flash image exists in secondary flash. The most
reliable way to ensure this is to reboot the switch from the flash image
you want to retain. For example, if you are planning to erase the primary
image, then first reboot from the secondary image to verify that the
secondary image is present and acceptable for your system:

HP4108# boot system flash secondary

Then erase the OS in the selected flash (in this case, primary):
