Upgrade Element software
To upgrade NetApp Element software, you can use the NetApp Hybrid Cloud Control UI,
REST API, or the HealthTools suite of tools. Certain operations are suppressed during an
Element software upgrade, such as adding and removing nodes, adding and removing
drives, and commands associated with initiators, volume access groups, and virtual
networks, among others.
What you'll need
• Admin privileges: You have storage cluster administrator permissions to perform the upgrade.

Description
Verifies that the number of
asynchronous results in the
database is below a threshold
number.
Verifies that there are no upgrade
blocking cluster faults (as defined in
Element source).
Measures the upload speed
between the storage node and the
management node.
Verifies that nodes have
connectivity to the management
node serving upgrade packages
and estimates connection speed.
Checks for kernel crash dump and
core files on the node. The check
fails for any crashes in a recent
time period (threshold 7 days).
Verifies the root file system has
sufficient free space to perform an
upgrade.
/var/log
Verifies that
meets some percentage free
threshold. If it does not, the check
will rotate and purge older logs in
order to fall under threshold. The
check fails if it is unsuccessful at
creating sufficient free space.
Verifies that there are no pending
nodes on the cluster.
