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 statuses 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 website:
