The file systems can be either of the following:

• External to the node, but internal to the HP XC system. “Mounting Internal File Systems Throughout the

HP XC System” (page 141) describes this situation.

The use of csys is strongly recommended. For more information, see csys(5).

• External to the HP XC system. “Mounting Remote File Systems” (page 144) describes this situation.

NFS mounting is recommended for remote file system mounting.

Mounting Internal File Systems Throughout the HP XC System

This section describes how to mount a file system on a disk on one node of the HP XC system to other nodes

in the HP XC system using the following example: Consider an HP XC system whose nodes have the prefix

n. A file system is resident on a disk attached to n60 (this node has the disk_io role); the device name of

that file system is /dev/sdb1. The task is to mount the file system remotely on nodes n61, n62, and n63

at the mount point /scratch. Figure 15-1. depicts the relationship between the nodes.
