HP XC System Software Installation Guide Version 4.0

Table 2-6 Information Required for the Kickstart Installation Session (continued)
Description and User ActionItem
The /hptc_cluster file system is the global, or clusterwide, file system on an
HP XC system. This file system is shared and mounted by all nodes and contains
configuration and log file information that is required for all nodes in the system.
This file system is intended for XC management use; do not use it for user
accounts or job launching.
You have the option to create a disk partition for the /hptc_cluster file system
somewhere other than the installation disk (also known as the system disk) on
the head node. For example, you might want to create a partition for this file
system on an SFS server for failover capability or on another separate disk on
the head node.
The prompt is similar to the following:
Do you want to create the XC global file system
(/hptc_cluster) as a partition on the system disk? (y/n)
If you answer yes , the /hptc_cluster is created on the installation disk. Be
aware that placing this file system on the installation disk does not provide any
type of failover capability.
If you answer no to this prompt, you must manually create and mount the
/hptc_cluster file system somewhere else. Section 3.6 (page 61) provides
instructions at the appropriate point in the process.
Where to create a partition
for the /hptc_cluster file
system
If an existing disk partition table that can be reused is detected on the head node
installation disk, you are prompted to reuse the existing partitions or apply the
HP XC default disk partition table. Choosing the default disk partition table
overwrites any data on the installation disk.
Software RAID-1 automatically creates disk partitions, so if you elect to configure
software RAID-1 on the system disk, you are not prompted to re-use existing
partitions.
The prompt is similar to the following:
Would you like to reuse the existing partition table
or do you want to use the XC default partition table?
Enter "r" to reuse or "d" to use the XC default:
The default partition table is listed in Table 2-3 (page 38).
If the existing disk partition table cannot be reused, you have the option to exit
the installation process to repartition the system disk manually. Otherwise, you
can continue the installation process and apply the default partition table.
The following messages are displayed if a calculated disk partition size exceeds
the size limit and the maximum partition size is applied:
Instituting a cap on the boot partition.
Instituting a cap on the root partition.
Instituting a cap on the /var partition.
Instituting a cap on the /hptc_cluster partition.
A portion of the disk is not partitioned.
For some configurations, the 4 GB limit on the size of the /hptc_cluster partition
might be too small. See Section 2.1.5 (page 38) for more information.
