HP UX 11i v2 Networking Software manual Upgrading Image Files, Understanding the Upgrade Process

The system only has enough flash memory to store:

•one image file (active)

•one system image (inactive)

•one recovery image

Occasionally, the user will have to manually delete either an image file or a system image from the system to make room for new software. Detailed information on the delete command can be found at “delete” (page 194).

•Active Image The term “Active Image” refers to the current System Image. An installed, or “active” image has gone through the entire upgrade process. The System-Image usually has a slash (/) in its name. Do not modify or delete the installed system-image.

•Inactive Image An inactive image is one that has been downloaded, but has not been installed; therefore it is not the active, or “system” image.

The HP Fabric Switch OS can only store one inactive image. Delete inactive images through the CLI (refer to (page 90)).

•Recovery Image The Recovery Image is a default image that comes installed on the system. The Recovery Image can be used to quickly restore operation to the system if an image upgrade should fail.

Log Files Log files are text files that record activity, including configuration changes. Depending on size, log files are rotated and compressed. The system checks the size of the active log file hourly, and when it exceeds 1 MByte, the active log file, ts_log, is closed, compressed, and renamed ts_log.1.gz. Other ts_log.x.gz files are incremented by 1.

Log files can also be exported from the system by using the copy command.

Upgrading Image Files

Understanding the Upgrade Process

Only cards with an oper-status of “up” are updated. If a card is down when you run install, or a card is added after running install, bring up the card and run install again. Specify the same image file. If the image is already installed on a card, that card is skipped. Be sure to specify boot-config again so that all cards know to boot off the same system image.

Image Upgrade Procedure Summary

The system upgrade process is summarized in the following steps:

1.Set up the hardware connection for the upgrade.

2.Verify the installed system-image version number.

3.Download an image file from a network-accessible ftp server. or

Download an image file remotely from a tftp server.

4.Install the new system-image.

5.Configure the CLI to use the appropriate configuration file the next time it reboots.

6.If you have made any configuration changes, save the current configuration so you can restore the configuration after rebooting the system.

7.Reboot the system.

The following are detailed steps for completing an image upgrade:

1. Set-Up the Hardware Connection
