Switch Memory and Configuration

Using Primary and Secondary Flash Image Options

xmodem should not be used over the OA serial console. It should only be used over the USB serial console connection.

Download Interruptions. In most cases, if a power failure or other cause interrupts a flash image download, the switch reboots with the image previously stored in primary flash. In the unlikely event that the primary image is corrupted, as a result of an interruption, the switch will reboot from secondary flash and you can either copy the secondary image into primary or download another image to primary from an external source. Refer to Appendix A, “File Transfers”.

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.

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.

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 6-15to 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
