Upgrading using the Linux installer

When upgrading, it is important to remove any activation files from MSS associated with previous versions of Host Access for the Cloud. Leaving obsolete activation files in place may result in limited access to sessions.

What's required before upgrading?

Administrative privileges for the operating system.
The cluster will be unavailable for end users during the upgrade process. We recommend planning a maintenance window accordingly.
Each node in the cluster must be in a Ready state before you attempt to upgrade.

Upgrade steps

To upgrade your product, first ensure all nodes in the deployment are in a Ready state. Then perform these steps:

From the Micro Focus download site, download the Linux installer script (install*.sh) for your product.
Enable execute permissions for the installer:

chmod 744 install*.sh
On each node in the cluster, update one node at a time by repeating the following steps:

a. Copy the installer to the node, run the Linux install script (.sh) with elevated privileges, (for example, sudo), to upgrade the product.

b. After the upgrade is complete, the verification tool automatically runs.
- If verification succeeds, the services will automatically start.
- If verification fails, review the troubleshooting steps.
c. After the CSP service starts, wait until the updated node shows a status of Ready. The cluster status can be checked by running the following command with elevated privileges: cspctl status
- Throughout the cluster upgrade process, it is normal to see warnings and errors in output of cspctl status. These will clear once the entire upgrade process is complete.
- It can take up to 15 minutes for the node to become Ready.
d. Move on to the next node in the cluster.
After all of the nodes in the cluster have been updated, on any node in the cluster with elevated privileges, run: cspctl cluster scale
Wait for the cluster to return to a healthy state with all nodes showing Ready using: cspctl status. This process can take up to 15 minutes.
