Intersight Virtual Appliance 1.1.0-0 Upgrade Behavior — Impact of CentOS 7 to AlmaLinux 9 Migration
Starting with Intersight Virtual Appliance Release Version 1.1.0-0, the underlying operating system is AlmaLinux 9.
Note |
It is highly recommended that you take a snapshot of the appliance VM as well as a backup of the appliance before you start the upgrade process. |
The following information highlights the key aspects of this migration:
-
Starting with Intersight Virtual Appliance Release Version 1.1.0-0, all new Appliance and Assist installations will be based on AlmaLinux 9.
-
Existing Appliance and Assist installations on version 1.0.9-631 or later that upgrade to version 1.1.0-0 or later will upgrade in-place to AlmaLinux 9.
-
Upgrading to version 1.1.0-0 directly from version 1.0.9-615 or older will fail. Therefore, while upgrading to version 1.1.0-0 from version 1.0.9-615 or older, do the following:
-
Ensure that the appliance meets the disk requirements. For more information, see Resource Requirements.
-
Upgrade to one of the following versions before upgrading to version 1.1.0-0.
-
1.0.9-631
-
1.0.9-655
-
1.0.9-675
-
1.0.9-677
-
-
-
When an existing Appliance or Assist upgrades to version 1.1.0-0, expect the following behavior:
-
The upgrade will take at least 4 hours to complete and will reboot multiple times.
-
The Appliance web UI, REST API, and CLI interfaces may not be available. You can monitor the progress of the upgrade on the VM console.
-
It is STRONGLY RECOMMENDED that you DO NOT manually reboot the Appliance or Assist VM during the upgrade process as it may damage the VM and potentially disrupt the upgrade process.
-
-
Installation and upgrade bundle sizes for release version 1.1.0-0 are larger than the ones for the previous releases due to the switch to AlmaLinux.
