Storage Manager may need to be started following the HA
conversion if the system was in config mode at the time that HA

components, click the
Start
button in the Storage Manager panel of
the
Tools > System Control
page.
GUI Feedback During HA Conversion
There are some indications within the GUI that the system is being
upgraded. Here are some notes about this visual feedback:
• After the StorNext upgrade has completed, and the HA
configuration has been done, the GUI for the secondary MDC node
provides a message stating it is not the primary MDC node and a
link to launch the primary MDC node.
Caution:
Do not login to the GUI of the secondary MDC node at any
point during the upgrade/HA conversion process. System
configuration and licensing for the system could be
compromised.
• When you are able to log into the primary /node, after accepting the
EULA, the system will automatically display the
Tools > System
Control
page. Click the
Start
button to restart the Storage Manager
components.
• Wait until the system icons for both MDC nodes of the system as
well as File System and Storage Manager are green, which indicates
normal operation.

• If you use the secondary MDC node as a DDM mover, make sure the
file systems are mounted.
