Use the Bring Cluster Services Online task
to select nodes and manage how cluster services run on them.
Fields
- Choose nodes on which to start cluster services
- Select one or more nodes to start clusters services.
- When to Start
- Select when and how cluster services start.
- Start now
- Immediately starts cluster services.
- Start on system restart
- Starts cluster services each time the system is restarted.
- Start now and on system restart
- Immediately starts cluster services and also starts cluster services
each time the system is restarted.
- Manage resource groups
- Select whether to manually manage the resource groups or have
them automatically managed by the system.
- Automatically
- Select this option for the cluster to automatically bring resource
groups online based on the configuration settings and the cluster
state of the resource group. The system also monitors the availability
of those resource groups and applications.

that remains offline, when the cluster services starts. Each resource
group is started manually to bring it online.

- Select Yes or No
- Yes
- Uses the wall command to broadcast cluster
services startup messages to every active terminal on each node.
- No
- Cluster services startup messages are not broadcast.
- Startup cluster information daemon
- Select Yes or No.
- Yes
- The cluster information daemon starts and provides status information
about the cluster.
- No
- The cluster information daemon does not start.
- Yes with consistency group support
- The cluster information daemon starts, provides status information
about the cluster, and ensures that a consistent state of the application
data on the disk is maintained if a failure occurs in the host machine,
software, or the storage subsystem.
- Ignore verification errors
- Select Yes or No.
- Yes
- Verification errors are ignored and cluster services start on
all of the specified nodes.
Note: This option is not preferred and
is done at the direction of the IBM® personnel.
- No
- Nodes that have verification errors cannot start cluster services.
Note: If
a verification error occurs on a node that is not used to start cluster
services, that verification error is ignored.
- Automatically correct errors
- Select how verification errors are corrected.
- Yes
- Attempts to automatically correct the verification errors that
affect starting the cluster services.
Note: Not all verification errors
can be corrected automatically; some might need to be corrected manually.
