Before you update nodes individually,
ensure that the system is ready for the update.
After you verify that the prerequisites for a manual
update are met, follow these steps:
- Use the management GUI to display the nodes in the system and record this information.
For all the nodes in the system,
verify the following information:
- Confirm that both canisters are online.
- Identify which canister is acting as the configuration
node.
- Record the service IP address for each canister.
- If you are using the management GUI, view External Storage to ensure that everything
is online and also verify that internal storage is present.
- If you are using the command-line interface, submit this
command for each storage system:
lscontroller controller_name_or_controller_id
where
controller_name_or_controller_id is the name or ID of the storage system.
Confirm that each storage
system has degraded=no status.
- Verify that all hosts have all paths available
to all the volumes that are presented to them by the system.
Ensure that the multipathing driver is fully redundant, with
every path available and online.
- If you did not do so previously, download
the installation package for the level that you want to install. You can download the
most current package from the following website:
