Local Switch Software Replacement and Removal

This section describes commands for erasing a software version and copying
an existing software version between primary and secondary flash.
N o t e
It is not necessary to erase the content of a flash location before downloading
another software file. The process automatically overwrites the previous file
with the new file. If you want to remove an unwanted software version from
flash, ProCurve recommends that you do so by overwriting it with the same
software version that you are using to operate the switch, or with another
acceptable software version. To copy a software file between the primary and
secondary flash locations, refer to "Copying a Switch Software Image from
One Flash Location to Another", below.
The local commands described here are for flash image management within
the switch. To download a software image file from an external source, refer
to Appendix A, "File Transfers".
Copying a Switch Software Image from One Flash Location to
Another. When you copy the flash image from primary to secondary or the
reverse, the switch overwrites the file in the destination location with a copy
of the file from the source location. This means you do not have to erase the
current image at the destination location before copying in a new image.
C a u t i o n
Verify that there is an acceptable software version in the source flash location
from which you are going to copy. Use the show flash command or, if necessary,
the procedure under "Determining Which Flash Image Versions Are Installed"
on page 6-14 to verify an acceptable software version. Attempting to copy from
a source image location that has a corrupted flash image overwrites the image
in the destination flash location. In this case, the switch will not have a valid
flash image in either flash location, but will continue running on a temporary
flash image in RAM. Do not reboot the switch. Instead, immediately download
another valid flash image to primary or secondary flash. Otherwise, if the
switch is rebooted without a software image in either primary or secondary
flash, the temporary flash image in RAM will be cleared and the switch will go
down. To recover, refer to "Restoring a Flash Image" on page C-68 (in the
"Troubleshooting" Appendix).
