HP XC System Software Installation Guide Version 3.2.1

2. Specify a quorum server node name or a full path to the lock LUN (for example, /dev/sdb1,
where 1 is the partition number) if you have configured availability sets to use Serviceguard
as the availability tool . See “Deciding on the Method to Achieve Quorum for HP Serviceguard
Clusters” (page 80) or the Serviceguard documentation for more information.
Executing C25syslimits sconfigure
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
OR
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:
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
4. 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 217) for information about how to determine the QsNet
II
network
type for the system.
5. 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]:
6. Specify how you want to configure improved availability of the dbserver service if you
have configured it for improved availability. 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
Executing C12dbserver gconfigure
Availability can be configured for dbserver in one of several ways.
The choices are:
1: standard
2: serviceguard
A choice of 'standard' (1) means no improved availability.
Enter the number corresponding to the way to configure availability []: 2
Executing C20gmmon gconfigure
