HP XC System Software Installation Guide Version 3.1

NOTE: Table 3-3 (page 48) describes each prompt and provides information to help you with your

answers.

1. When you are prompted to enter the number of NFS daemons required on the system; accept the

default value.

Configuring system wide functions / policies / behaviors

Executing C02hptc_cluster_sfs sconfigure

Executing C02ssh_config sconfigure

Executing C10cluster_fstab sconfigure

Executing C20sysparams sconfigure

NFS daemon tuning:

Given that there are 6 nodes in this cluster, enter the number of

NFS daemons that shall be configured to support them [8] : Enter

The default value for the number of NFS daemons scales according to the number of nodes in the

system. The default value represents the number of NFS daemons required on the head node to

adequately support serving the /hptc_cluster file system. Table 3-7 lists the default values.

2. If you have configured availability sets to use Serviceguard as the availability tool, specify a quorum

server node name or a full path to the lock LUN (for example, /dev/sdb1, where 1 is the partition

number). See “Deciding on the Method to Achieve Quorum for Serviceguard Clusters” (page 41) or

the Serviceguard documentation for more information.

Configuring service specific functions

Executing C03avail gconfigure

You need to configure quorum for the availability set with

members n16 and n14.

Valid choices are quorum server [q] or lock LUN [l]: [q] Enter

Please provide the name of the quorum server? [] node_name

Please provide the name of the lock LUN [ ] full_path_to_lock_LUN

Executing C05pdsh gconfigure

3. Specify the Network Time Protocol (NTP) server. The head node is automatically configured as the

system's NTP server if another server is not specified, but you have the option to provide up to four

external NTP servers instead.

If the HP XC system will be integrated with HP StorageWorks Scalable File Share (HP SFS), the HP

XC and HP SFS systems must be synchronized to a common time server. Therefore, do not take the

default response; instead, enter the same external time server that will be used for the HP SFS system.

Executing C08ntp gconfigure

Configuring the following nodes as ntp servers for the cluster:
