11.
Enter span-list-cluster-uuids span_label to display the cluster
serial number (UUID) to which the storage pool belongs.
The UUID is written into the storage pool's configuration on disk (COD).
The COD is a data structure stored in every SD, which provides
information how the different SDs are combined into different stripesets
and storage pools.

Enter span-assign-to-cluster span_label to assign all the spans to
the new server.

Confirm all final settings, IP addresses, customer contact information,
service restarts, client access, and that customer expectations are all in
place. Features such as replication and data migration should all be
confirmed as working, and all file systems and storage pools should be
online.
Replacing a node within a cluster
Replacing a single node within a cluster assumes only two-node clusters and
the presence of an external SMU, which acts as a quorum device. This helps
to simplify the replacement process because a cluster preserves operational
state of the entire system beyond any single node failure. In this particular
scenario temporary license keys are not required.

then download another diagnostic to support. Permanent license keys
for the replacement server are normally provided within 7 days.
