Remote Upgrade

You can remotely upgrade the appliance software on a LogLogic LMI appliance or a LogLogic EVA instance from a computer with Windows, Linux, or macOS platform. This method is applicable in the following scenarios:

Category	Applicable to	Not applicable to
Number of appliances	One appliance at a time	Multiple appliances at a time
Setup	LogLogic LMI hardware appliances LogLogic EVA on VMware	LogLogic EVA on cloud and container platforms: Microsoft Azure AWS KVM Docker

• The computer can access the target appliance remotely via SSH, and must not have any settings that might interrupt the process, such as sleep mode or battery-saver mode.
• Python version 3 and the supported Paramiko library must be installed on the computer.
• Continuous power supply and network connectivity must be available till the process completes.

Procedure
1. Log in to the computer from where you want to perform the upgrade.
2. (Optional) To perform a dry run of the command before actually performing the upgrade, add the --dry-run option with the command:

   $> ./remote_upgrade.py --host <IP_address_of_LMI_appliance> --upgrade-file <filename_of_tar_file> --dry-run

   The dry run does not start the upgrade process; it checks the SSH connection to the target appliance and retrieves the versions of LogLogic LMI and LogLogic LSP on the target appliance.

3. Run the upgrade command in the following format:

   $> ./remote_upgrade.py --host <IP_address_of_LMI_appliance> --upgrade-file <filename_of_tar_file>

   For example:

   $> ./remote_upgrade.py --host 192.0.2.81 --upgrade-file loglogic-lmi-6.4.0-fileupgrade.tar

   Note: To upgrade an HA pair, provide the public IP address of the pair. If the IP address is not a public address, the upgrade process stops.

   The remote upgrade script performs the following tasks:

   1. Uploads the .tar file to the LogLogic LMI appliance or LogLogic EVA instance. If the .tar file exists on the appliance, then this step is skipped.
   2. Runs the health check script. If any check fails, the upgrade process stops.
   3. Performs the software upgrade on the LogLogic LMI appliance or LogLogic EVA instance.

• The appliance restarts.
• A log file is saved at the same location where the script is run.
• The state of Advanced Features before the upgrade are retained on the appliance after the upgrade.
