Software Package Upgrade

If required, Stromasys or your VAR will provide you with installation packages to update your Charon-SSP cloud instance.

In this case, perform the following steps:

Use SFTP to copy the RPM packages to your Charon OCI instance (see Data Transfer Options).
Connect to the host system using Charon Manager (see Connecting with the Charon Manager)
Shutdown the guest systems running on the host and stop the emulator.
Use SSH to connect to your Charon cloud instance (see SSH Command-Line Access).
Install the new RPM packages as described below.
Install the new Charon-SSP Manager package on your local Linux system as described below.
Connect to the host system using Charon Manager.
Start the emulator and boot the guest systems.

Charon-SSP OCI Installation Packages

The Charon-SSP packages are provided as RPM packages and (only Charon Manager) as Debian packages. You can download the required package(s) from Stromasys or receive them on a read-only medium, such as a CD-ROM. If you do not have the software package(s), please contact either Stromasys or your Value-Added Reseller (VAR) for further help.

The following table shows installation package names. The update of these packages is shown in the following sections.

Upgrading Charon Packages on the Charon-SSP OCI Instance

After copying the packages to the Charon-SSP OCI instance, install the packages as described below. For details, please refer to the relevant man-pages on Linux.

Step	Details
1	Cleanly shut down any running Solaris guest system and stop the emulator.
2	Log in to the Charon-SSP host on the cloud via SSH to the sshuser and become the root user (`sudo -i`).
3	Go to the directory where the packages have been stored: `# cd <package-location>`
4	Run upgrade command:
4	For systems with RPM package management (Red Hat, CentOS): `# yum update <package-name>`

Upgrading Charon Manager on the Management Linux System

There are two ways to upgrade the Charon Manager on the management Linux system.

Standard Linux Package Update

Step	Details
1	Log in as the root user.
2	Go to the directory where the packages have been stored: `# cd <package-location>`
3	Run upgrade command:
	For systems with RPM package management (Red Hat, CentOS): `# yum update <package-name>`
	For systems with Debian package management (Debian, Ubuntu): `# dpkg -i <package-name>`

Automatic Update upon First Connection to Updated Charon Host System

New feature in Charon-SSP 4.0.x and its pre-release versions.

If you connect to a Charon host system from a management system that uses an older version of the Charon Manager than the one used on the host system, you will be offered an automatic update to the version of the Charon host system. If the target host system is a newly installed Charon system, you will be prompted to set the management password before you get to the upgrade window (see Connecting with the Charon-SSP Manager for more information).

The following image shows a sample of the upgrade offer:

Confirm the upgrade by clicking on Yes. This will initiate the download and installation of the new version. If you work as a non-privileged user, you will be prompted for your password. To decline the automatic update, click on Cancel.

This mechanism also works for downgrades (i.e., if the Charon Manager version is newer than the version of the Charon host system it connects to, it can be automatically downgraded to the version of the target system).

Some future major changes in the Charon Manager and/or Agent may prevent the automatic upgrade. In such cases, follow the manual package installation steps.

Creating a New Instance with New Charon-SSP Version

One option to upgrade Charon-SSP OCI to a newer version is the creation of a new instance based on a new version of the Charon-SSP OCI image.

This may be applicable if

all important Charon instance files (e.g., vdisks and ISO images) are on a separate block storage volume that can easily be moved to a new instance,
the overall configuration of the Charon-SSP host system is not very complex, i.e., can be recreated without much time and effort,
a major host operating system upgrade is required.

Steps (only meant for illustration - the details could vary depending on the customer environment):

Create an instance with the new Charon-SSP version in the same subnet as the old instance (same security rules and key pair as old instance).
Shut down guest systems and stop running emulator instances on the old host system.
Backup emulated SPARC disks and configuration data on the old instance to the separate OCI disk volume.
If applicable, backup important system configuration files to the separate disk volume.
Stop the old instance.
Copy the Charon Manager kit from the new instance and install it on your local Linux system, or connect to the new instance via Charon Manager to initiate the automatic Charon Manager update.
Move the disk volume(s) and (if applicable) reserved IP addresses to the new instance.
Import the virtual SPARC configurations on the new system.
Adapt the host system configuration as needed.
Start the guest systems.
If everything works, terminate the old instance.

Please refer to the Oracle cloud documentation for OCI specific details.
