information.
Executing C25syslimits sconfigure

Configuring service specific functions
Executing C03avail gconfigure
You must configure a quorum method for the availability set with
members n1 and n2.
Valid choices are [q]uorum server or [l]ock LUN (q/l): [q]
Enter the host name of the quorum server []: host_name
OR
Enter the path of the lock LUN [ ] full_path_to_lock_LUN
5. 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 Scalable File Share (SFS), the HP XC head
node and the SFS server 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 SFS server.
Configuring service specific functions
Executing C05pdsh gconfigure
Executing C08ntp gconfigure
Configuring the following nodes as ntp servers for the cluster:
n16
You must now specify the clock source for the server nodes. If the nodes have
external connections, you may specify up to 4 external NTP servers. Otherwise,
you must use the node's system clock.
Enter the IP address or host name of the first external NTP server
or leave blank to use the system clock on the NTP server node: IP_address
Enter the IP address or host name of the second external NTP server or
leave blank if you have no more servers: Enter
Renaming previous /etc/ntp.conf to /etc/ntp.conf.bak
6. Supply the network type if the system has a QsNet
II
interconnect; the possible choices for
the system are displayed, and a default is provided:
Enter the network type of your system.
Valid choices are QMS16 or QMS32: [QMS32]: Enter
The network type reflects the maximum number of ports the fabric topology can support.
See Appendix H (page 233) for information about how to determine the QsNet
II
network
type for the system.
7. Specify how many node-level and top-level switches are in the system configuration if the
system has a QsNet
II
interconnect:
Enter the number of node level switches in your configuration [1-32]:
Enter the number of top level switches in your configuration [0-32]:
8. Specify how you want to configure improved availability of the hptc_cluster_fs service
if you have assigned the avail_node_management role to a node in an availability set. If
you have not configured an availability set with this service, omit this step and proceed to
the next step.
Executing C10hptc_cluster_fs gconfigure
Specify how to configure availability for hptc_cluster_fs:
1: standard (no improved availability)
2: serviceguard (use this tool for improved availability)
