• 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 Clustering System Switch OS can only store one inactive image. Delete inactive images
through the CLI (refer to page 78).
• 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: 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.
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.
About Copying/Downloading the Image Upgrading the HP Fabric Clustering System Switch OS requires several
steps, which are described in the following sections. One of the steps will be to copy the image before installing it.
There are options when copying the image into the system:
Once the image has been copied via the chosen method, refer to “4. Install a New Image” on page 77.
Image Upgrade Procedure Summary The system upgrade process is summarized in the following steps:
Step 1. Set up the hardware connection for the upgrade.
Step 2. Verify the installed system-image version number.
Step 3. Download an image file from a network-accessible ftp server.
or
Download an image file remotely from a tftp server.
Step 4. Install the new system-image.
Step 5. Configure the CLI to use the appropriate configuration file the next time it reboots.
Step 6. If you have made any configuration changes, save the current configuration so you can restore the
configuration after rebooting the system.
