Workflow: stop and start DR NSP clusters

Description
CAUTION 

CAUTION

System Degradation

If the primary NSP cluster and associated primary components outside the cluster are not in the same data center, the maintenance shutdown described in this workflow may cause an undesired DR switchover of one or more components, which can be service-affecting.

Before you attempt to use this workflow, you must ensure that the primary NSP cluster and associated primary components outside the cluster are in the same data center. If not, perform the appropriate procedure to ensure that all component roles in each data center are aligned.

The following is the sequence of high-level actions required to stop and start the primary and standby NSP clusters in a graceful manner for maintenance purposes.

See the following procedures for information about stopping and starting a cluster:

Stages
Perform orderly shutdown of standby components outside NSP cluster
 
1 

If the NSP deployment includes an auxiliary database, stop the auxiliary database cluster in the standby data center, as described in How do I stop an auxiliary database cluster?.

2 

If the NSP deployment includes the NFM-P, perform the following steps.

  1. Stop each Reserved NFM-P auxiliary server of the standby main server; see How do I stop an auxiliary server?.

  2. Stop each Preferred NFM-P auxiliary server of the standby main server; see How do I stop an auxiliary server?.

  3. Stop the standby main server; see How do I stop a main server?.

  4. Stop the standby main database; see How do I stop a main database?.

Perform standby NSP cluster maintenance
 
3 

Stop the standby NSP cluster, as described in How do I stop an NSP cluster?.

4 

Perform the required maintenance on the standby cluster.

5 

Start the standby cluster, as described in How do I start an NSP cluster?.

Switch NSP cluster roles
 
6 

Perform an activity switch to change the standby cluster role to primary, as described in How do I perform an NSP DR switchover?.

The standby cluster assumes the primary role.

Perform orderly startup of standby components outside cluster
 
7 

If the NSP deployment includes the NFM-P, perform the following steps.

  1. Start the former standby main database; see How do I start a main database?.

  2. Start the former standby main server; see How do I start a main server?.

  3. Start each Preferred NFM-P auxiliary server of the former standby main server; see How do I start an auxiliary server?.

  4. Start each Reserved NFM-P auxiliary server of the former standby main server; see How do I start an auxiliary server?.

8 

If the NSP deployment includes an auxiliary database, start the auxiliary database cluster in the former standby data center; see How do I start an auxiliary database cluster?.

Perform orderly shutdown of former primary components outside NSP cluster
 
9 

If the NSP deployment includes the NFM-P, perform the following steps.

  1. Stop each Preferred NFM-P auxiliary server of the former primary main server; see How do I stop an auxiliary server?.

  2. Stop each Reserved NFM-P auxiliary server of the former primary main server; see How do I stop an auxiliary server?.

  3. Stop the former primary main server; see How do I stop a main server?.

  4. Stop the former primary main database; see How do I stop a main database?.

Perform former primary NSP cluster maintenance
 
10 

Stop the former primary cluster, as described in How do I stop an NSP cluster?.

11 

Perform the required maintenance on the former primary cluster.

12 

Start the former primary cluster, as described in How do I start an NSP cluster?.

Perform orderly startup of former primary components outside cluster
 
13 

If the NSP deployment includes the NFM-P, perform the following steps.

  1. Start the former primary main database; see How do I start a main database?.

  2. Start the former primary main server; see How do I start a main server?.

  3. Start each Preferred NFM-P auxiliary server of the former primary main server; see How do I start an auxiliary server?.

  4. Start each Reserved NFM-P auxiliary server of the former primary main server; see How do I start an auxiliary server?.

14 

If the NSP deployment includes an auxiliary database, start the auxiliary database cluster in the former primary data center; see How do I start an auxiliary database cluster?.

Restore initial primary/standby NSP cluster roles
 
15 

If required, perform an activity switch to restore the initial primary and standby roles, as described in How do I perform an NSP DR switchover?.
