HP Secure Key Manager - Manual (Page 107)

IMPORTANT:
You must be running the base release upon which the patch is built before upgrading to the patch
release. You cannot upgrade directly from a
previous base release to a patch.
If you receive a software patch from HP, follow the installation instructions that come with it.
Rolling back software
Occasionally it is necessary to roll back software to a previous version. The SKM allows you to roll
back one version of the software. As such, we recommend that you avoid doing multiple patch
upgrades on the same base release. Instead, roll back from the patch release to the base release
before doing the upgrade to the patch release.
NOTE:
The software rollback process can be performed from the CLI only; it cannot be performed from the
Management Console.
IMPORTANT:
Before performing a software rollback, it is very important that you create a backup of your existing
configuration. In most cases, you can restore a backup after you have done the software rollback. If
some features are supported in the more recent version of the software and not the base version you
are rolling back to, those features will not be available after the software rollback.
System Health page
The System Health feature provides information about the SKM's power supplies and cooling fans.
When the SKM detects a change in the status of a power supply unit or cooling fan, the System Health
page reflects the change and displays a warning message if appropriate. In addition, if your system
is configured for SNMP, the SKM sends an SNMP trap to the SNMP Management Station indicating
the change in status.
This page contains the following sections:
• Refresh Page
• Power Supply Status
• Cooling Fan Status
Refresh page
The Refresh Page section controls how frequently the System Health page is refreshed. When the
page is refreshed, the values displayed on the page are updated. The refresh interval you specify on
the System Health page does not affect the refresh interval on the CLI.
