Found these instructions on a technote (TECH179999):
To apply the patch, follow these steps:
1. Locate the .tar file in C:\Program Files\Symantec\Backup Exec\Agents\ or C:\Program Files\Symantec\Backup Exec\Agents\RALUS. These files can be copied to your RALUS/RAMS/RMALS target system and contain the latest available RALUS/RAMS/RMALS patch. Symantec does not recommend uncompressing these files on the Windows media server. Download the hotfix .tar file.
2. Transfer the .tar file to the Linux/Unix system. Note: If FTP is used to transfer the file, ensure that binary mode is enabled prior to GETting or PUTting the .tar file. Most GUI-based FTP applications will do this automatically. For more information, refer to the FTP client documentation. Do not untar the file on a Windows system as this may corrupt the data.
3. Log in to a command line on the target system with root privileges.
4. Extract the file to a temporary location:
# cd /tmp
# tar -xvf <path and filename, for instance /home/user/ralus1364HF301340-Linux_301342.tar>
5. Run this command and follow any prompts on screen:
# ./installraluspatch.sh
To verify the hotfix installed on the RALUS/RAMS/RMALS system:
$ cat /var/VRTSralus/ralus.ver
The file will contains a number in the format of <product revision>.<hotfix number>.
Note: RALUS/RAMS/RMALS hotfixes cannot be uninstalled. Removing and reinstalling RALUS/RAMS/RMALS from the installation media will revert the system back to the base version of RALUS/RAMS/RMALS with no hotfixes installed.
Note: As with the installation of any patch, it is important to run a full backup of the resources on each Agent for Windows and RALUS/RAMS/RMALS system for recovery purposes after installing the patch.
