$ sudo ./qs_inst_188.8.131.525.bin
and follow the prompts to complete the upgrade.
- After the upgrade script completes, some QoreStor processes will continue behind the scenes. The system will not be operational until these processes complete. Execute the command watch /opt/QoreStor/bin/system —show to monitor the progress of QoreStor services.
NOTE: In some instances, some DMAs may experience timeout errors when trying to access QoreStor containers after an upgrade. If this occurs, wait until QoreStor is fully online, then restart the DMA.
Upgrading the QoreStor Operating System
Review the requirements and considerations below before upgrading the operating system on the QoreStor server.
- Ensure that the OS version and kernel version are supported. Refer to the QoreStor Interoperability Guide for up-to-date information.
- When VTL support is enabled during the QoreStor installation, modules are installed that are specific to the kernel version at the time of installation. If the operating system on the QoreStor server is updated, these modules may not work correctly. When updating the operating system on the VTL-enabled QoreStor server, peform the actions below:
- After updating the OS, uninstall QoreStor while preserving the repository. Refer to Uninstalling QoreStor
- Re-install QoreStor, making sure to use the existing repository during installation.
NOTE: If QoreStor was installed without enabling VTL support, this procedure is not required.
