Hitachi NAS Platform 4000 Series - Replacing a Single Server with an External SMU

7. If the server does not r
ecognize the system drives, enter fc-link-reset to r
eset
the ber paths.
8. Enter sdpath to display the path to the devices (system drives) and which hport and
stor
age port are used.
9. Enter sd-list to verify the system drives statuses as OK and access is allowed.
10. Enter span-list to verify the storage pools (spans) are accessible.
Note: In this instance, cluster is synonymous with the standalone server.
11. Enter span-list-cluster-uuids span_label to display the cluster serial
number (UUID) to which the stor
age pool belongs.
The UUID is written into the stor
age pool’s conguration on disk (COD). The COD is a
data structure stored in every SD, which provides information how the dierent SDs
are combined into dierent stripesets and storage pools.
12. Enter span-assign-to-cluster span_label to assign all the spans to the new
server.
13. Verify the IP routes, and enable all the EVSs for le services in case they are
disabled.
14. Recongure any required tape backup application security.
15. Navigate to Home > Status & Monitoring >
Event Logs, and click Clear Event
Logs.
16. Navigate to Home > Status & Monitoring > System Monitor and verify the server
status:
■ If the server is operating normally, and is not displaying any alarm conditions,
run a backup to capture the revised conguration, and then download another
diagnostic to support. Permanent license keys for the replacement server are
normally provided within 7 days.
■ If the server is not operating normally for any reason, contact support for
assistance.
17. Conrm all nal 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 conrmed as working, and all le
systems and storage pools should be online.
Replacing a single server with an external SMU
Note that if it is a single server with an external SMU that is nonfunctioning, and does not
have a recent backup saved o platform, then a challenging and manual recovery
process is necessary. If this circumstance is encountered, call the support organization
for a copy of the system's latest diagnostics les, if available, to be used as a guide in
reestablishing the system manually. The data and le systems will remain intact
independent of the replacement and without a backup.
