Disabling and enabling replication rules

Disabling a replication rule suspends replication of all data to which the rule applies. For example, you can disable replication of active backup data in all client nodes and file spaces that have the replication rule ACTIVE_DATA.

About this task

Disabling a replication rule can be useful if, for example, you replicate groups of normal-priority and high-priority client nodes on different schedules. For example, suppose that the data that belongs to some client nodes is assigned the ALL_DATA_HIGH_PRIORITY replication rule. The data that belongs to other client nodes is assigned the ALL_DATA replication rule. The client nodes are separated into groups, in which some of the nodes in each group have high-priority data and other nodes in the group have normal-priority data.

You schedule replication for each group to take place at different times. However, a problem occurs, and replication processes take longer than expected to complete. As a result, the high-priority data that belongs to client nodes in groups that are scheduled late in the replication cycle is not being replicated.

To replicate the high-priority data as soon as possible, you can disable the ALL_DATA rule and rerun replication. When you rerun replication, only the client node data that is assigned the ALL_DATA_HIGH_PRIORITY rule is replicated. After high-priority data is replicated and the problem that caused the delay is fixed, you can enable the ALL_DATA replication rule and resume scheduled replication processing.

You can disable or enable the following replication rules:

ALL_DATA: Replicates all backup, archive, and space-managed data. The data is replicated with a normal priority.
ACTIVE_DATA: Replicates only the active backup data. The data is replicated with a normal priority.
ALL_DATA_HIGH_PRIORITY: Replicates backup, archive, and space-managed data. The data is replicated before data that has a normal priority.
ACTIVE_DATA_HIGH_PRIORITY: Replicates only active backup data. The data is replicated before data that has a normal priority.

To disable and enable replication rules, complete one of the following steps:

Procedure

To disable a replication rule, issue the UPDATE REPLRULE command and specify STATE=DISABLED. For example, to disable the replication rule ACTIVE_DATA_HIGH_PRIORITY, issue the following command:
```
update replrule active_data_high_priority state=disabled
```
To enable a replication rule, issue the UPDATE REPLRULE command and specify STATE=ENABLED. For example, to enable the replication rule ACTIVE_DATA_HIGH_PRIORITY, issue the following command:
```
update replrule active_data_high_priority state=enabled
```
