Stage 1: Bringing up the cluster for the first time

What to do to bring up the cluster

After cabling the nodes and storage together, you must connect the cluster to the network, apply power to the system, and configure the nodes of the cluster.

Bringing up the new cluster

To bring up the cluster for the first time, complete the following steps.

Step	Action
1	Connect both nodes to the network, as described in the hardware and service documentation.
2	Turn on the power to the disk shelves and wait 30 seconds for the electronics to complete initialization.
3	If you are configuring...	Then...
	Storage systems that were already in use	Turn on the power to both storage systems and wait for the system prompt. Attention Press the Delete key to stop booting if the system starts to boot. Proceed to Stage 2: Running diagnostics.
	New storage systems	Apply power; the storage systems enter the `setup` program automatically. Proceed to Step 4.
4	Use the `setup` program to configure both storage systems. For more information about running setup on a system set up for clustering, see About running setup on clustered systems. For more information about running setup, see the Software Setup Guide.

About running setup on clustered systems

When the setup program runs on a storage system that is set up for clustering, setup prompts you to answer some questions specific for clusters. The following list outlines some of the questions about your installation that you should think about before proceeding through the setup program:

Do you want to configure virtual interfaces (VIFs) for your network interfaces?
For information about VIFs, see the Network Management Guide.

Note
You are advised to use VIFs with clusters to reduce SPOF (single-points-of-failure).
How do you want to configure your interfaces for takeover?
- For information about configuring network interfaces for clusters, see Configuring network interfaces for clusters.
- For information about using setup to configure shared interfaces, see Using setup to configure shared interfaces.
- For information about using setup to configure dedicated interfaces, see Using setup to configure dedicated interfaces.
- For information about using setup to configure standby interfaces, see Using setup to configure standby interfaces.
  Note
  If you do not want to configure your network for clustering when you run setup for the first time, you can configure it later in the cluster configuration process, either by running setup again, or by using the ifconfig command and editing the /etc/rc file manually. However, you must provide at least one local IP address to exit setup.

Using setup to configure shared interfaces

To use setup to configure shared interfaces, complete the following steps.

Step	Action
1	Enter the IP address for the interface you are configuring. Example Please enter the IP address for Network Interface e0 []:nnn.nn.nn.nnn nnn.nn.nn.nnn is the local address for the node you are configuring.
2	Enter the netmask for the interface you are configuring, or press Return if the default value is correct. Example Please enter the netmask for Network Interface e1 [255.255.0.0]:
3	Specify that this interface is to take over a partner IP address. Example Should interface e1 take over a partner IP address during failover? [n]: `y`
4	Enter the IP address or interface name of the partner. Example Please enter the IP address or interface name to be taken over by e1 []: nnn.nn.nn.nnn Note If the partner is a VIF, you must the interface name.

Using setup to configure dedicated interfaces

To use setup to configure dedicated interfaces, complete the following steps.

Step

Action

Enter the IP address for the interface you are configuring.

Example

Please enter the IP address for Network Interface e0 
[]:nnn.nn.nn.nnn

nnn.nn.nn.nnn is the local address for the node you are configuring.

Enter the netmask for the interface you are configuring, or press Return if the default value is correct.

Example

Please enter the netmask for Network Interface e1 
[255.255.0.0]:

Specify that this interface does not take over a partner IP address.

Example

Should interface e1 take over a partner IP address during 
failover? [n]: n

Using setup to configure standby interfaces

To use setup to configure standby interfaces, complete the following steps.

Step	Action
1	Do not enter an IP address for a standby interface, press Return. Example Please enter the IP address for Network Interface e0 []:
2	Specify that this interface is to take over a partner IP address. Example Should interface e1 take over a partner IP address during failover? [n]: `y`
3	Enter the IP address or interface name of the partner. Example Please enter the IP address or interface name to be taken over by e1 []: nnn.nn.nn.nnn Note If the partner is a VIF, you must use the interface name.

Step

Action

Do not enter an IP address for a standby interface, press Return.

Example

Please enter the IP address for Network Interface e0 []:

Specify that this interface is to take over a partner IP address.

Example

Should interface e1 take over a partner IP address during 
failover? [n]: y

Enter the IP address or interface name of the partner.

Example

Please enter the IP address or interface name to be taken 
over by e1 []: nnn.nn.nn.nnn

Note
If the partner is a VIF, you must use the interface name.
