RM Redundancy Setup - Removing RM Redundancy
Note:
When performing any redundancy removal actions, whether removing a host from the group or
the group itself, all actions are performed from the Active RM. No actions are required from the
Standby RM.
Remove
Standby
Host
from
Redundant
Group
In certain upgrade, downgrade, or configuration situations, you may be required to remove the
standby RM while keeping the redundancy group intact. For example, you may wish to make a standby
RM a standalone RM or you wish to make a standby RM part of a different redundancy group.
To remove only the standby RM, proceed as follows:
1.
Log in to the
Active
or
VIP
RM.
2.
From the
System
tab, click the triangle [
] symbol next to the
Redundancy
container to expand
the menu, then click on
Hosts.
3.
Locate the row entry in which the
Host Type
indicates
Standby
and click the trash
(
)
icon.
4.
From the confirmation pop-up box, click
Delete
to confirm.
The resulting
Redundancy Host
menu should now show only the Active RM as a host.
Note:
Once the Standby RM has been removed from the redundancy group, the Standby (now a
standalone) will not be accessible until its services restart—about 30 seconds.
Remove
Redundancy
Group
In certain upgrade, downgrade, or configuration situations, you may be required to completely tear
down redundancy between two RMs. Tearing down redundancy means removing both the standby
host and the redundancy group itself, thus leaving no trace of redundancy on either system.
To remove the redundancy group from the RM, proceed as follows:
1.
Log in to the
Active
RM (
not
the VIP).
2.
Remove the
Standby
host first as described in the previous section,
