2. Add the following line or lines to the bottom of the file to enable software RAID-0 or RAID-1. Replace
node_prefix[n-n] with the node prefix and the range of nodes on which you want to enable software
RAID (for example n[1-4,7,9]). You must include a space before and after the equal sign (=).
SOFTWARE_RAID0_NODES = node_prefix[n-n]
SOFTWARE_RAID1_NODES = node_prefix[n-n]
3. Save your change and exit the file.
3.7.10 Create Local User Accounts
This task is optional. If you intend to create local user accounts on the HP XC system rather than manage
user accounts through another user authentication method (such as NIS or LDAP), use the Linux adduser
command to create local user accounts on the system now, before the system is configured.
See the HP XC System Software Administration Guide if you need more information about creating local user
accounts.
Special Considerations for Nagios and LSF
During the system configuration phase, the cluster_config command attempts to create a nagios
and an lsfadmin account for use by Nagios and LSF, respectively.
To use existing nagios and lsfadmin user accounts from a site wide NIS system (or some other external
user authentication system), you must manually create local XC accounts that mirror the site wide accounts
(with matching user identification (UID) and group identification (GID) values). In that way, the
cluster_config command uses these local accounts to properly configure Nagios and LSF with the
right file permissions, access, and so on.
3.7.11 Override Default User and Group Account IDs
This task is optional. Perform this task only if the default user and group IDs are not suitable for your
environment.
Table 3-5 lists the user and group account IDs that are configured by default on an HP XC system if they
are not already in use. If any of the default user and group identifiers conflict with other accounts or are
not suitable for your environment, you can override them by creating the user accounts manually now
(before running the cluster_config utility).

3.7.12 Customize Client Node Disk Partitioning
This task is optional. Perform this task only if you want to change the default partition layout on client
nodes.
The HP XC client node imaging process requires a single system disk on each client node for the operating
system installation. Client node disk devices are partitioned automatically as part of the automated client
imaging process.
Table 3-6 lists the default disk partition layout on client nodes. Partition sizes are created as a percentage
of available disk space after subtracting the total swap size.
