Please note the following:
• The UIDs for the
quantumdb
and
tdlm
users and the
adic
group
must
be identical on both MDC nodes of an HA pair. If the UIDs are

permission errors), which in turn prevents storage manager from
fully starting up.
Follow these steps to configure HA:
1
From the StorNext GUI on MDC Node 1, choose
Tools > High
Availability > Convert
.
Figure 29 Tools > HA >
Convert
Caution:
On the
Tools > High Availability
page, it is critical that
you assign the Metadata network IP address in the
MDC Address
field and NOT the Management network
IP address.
