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.
- If you are using the management GUI, select to verify that all paths to all the volumes that are
mapped to the hosts are available. Confirm that the status of the
hosts are Online. A Degraded status indicates that the host cannot access mapped volumes.
Ensure that the multipathing driver is fully redundant, with
every path available and online.
- If you are using the command-line interface, enter the
following command to verify host paths to mapped volumes:
lshost host_name_or_host_id
where
host_name_or_host_id is the name or ID of
the host.
Confirm that each host has online status.
- 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 websites:
