Whenever you upgrade the UNIX file system of a client computer, you must uninstall the Base software and file system agent software prior to the operating system upgrade, and then reinstall these modules after the operating system upgrade.
Before You Begin
-
Identify the computers to be upgraded and what software is installed.
-
Ensure that you have all the information required before uninstalling, installing, or upgrading any software. The UNIX file system agent software must be re-installed using the same configuration as the original install, in order to access the backed up data and history from the previous installation.
Procedure
-
From the CommCell Console, on the client being upgraded, kill all jobs that are running, waiting, pending, or stopped.
For instructions, see Killing a Job.
-
From the CommCell Console, right-click the client and select Properties.
-
On the Activity Control tab, clear the Enable Backup and Enable Restore check boxes, and then click OK.
-
If required, uninstall the agent software in the following order: UNIX file system agent software, any other associated software besides the Base software (for example, MediaAgent software, WA SCSI driver software), and then the Base software.
Important
-
Do not delete the client’s agent icon in the CommCell Console. If you do, the associated backup data and history will be lost.
-
Note that this step is not necessary if you are completely replacing your operating system with a clean install; do this only if you are upgrading your operating system.
-
-
Upgrade, or install the new version of, the operating system.
-
Proceed as follows:
-
If required, reinstall the Base software.
-
Reinstall the UNIX File System agent.
Notes
-
The agent should be installed to the same directory in which it was previously installed.
-
Ensure the client is installed with the same Fully Qualified Domain Name or short domain name with which it had been previously installed.
-
-
Post-Upgrade Considerations
-
Install any updates or service packs that may have been made available after the release of the UNIX file system agent software.
-
Ensure that backups and restores are no longer disabled. If necessary, enable backups and restores from the Activity Control tab of the agent Properties dialog box.
-
It is recommended to run a full backup of the default subclient after performing an operating system upgrade to secure the new operating system data. Do not perform the following operations until a full backup has been run:
-
Full agent restore
-
System state restore
-
Synthetic full backup
-
-
Reinstall all other agents, including any post-release updates or service packs, in the same locations in which they were previously installed.
