IRIX
The file tree used by the ITO managed node software on IRIX is similar
to other SVR4 platforms and organised in the following way:
Figure 3-16 ITO Software on SGI IRIX Managed Nodes
Standalone Systems or NFS Cluster Servers
on SGI IRIX
In general, stand-alone systems are treated as cluster servers. The
cluster server exports the /opt file system with read-only permissions.
ITO software is located in /opt/OV, with the same logical and physical
path names.
NFS Cluster Client on SGI IRIX
In addition to the general rule for determining cluster clients described
in “Installation Tips for IRIX Managed Nodes” on page 70, there is also
one specific rule for IRIX:
IRIX cluster clients (both diskless, and normal disks) are those IRIX
systems that have either a /usr file system or /opt file system NFS
mounted. Their cluster server is the system to which /usr or /opt is
mounted. If the /opt file system is not already NFS mounted (only /usr
NFS mounted), then ITO mounts /opt to /opt of the cluster server:
