Installing a Series 700 Client on a Series 800
Cluster Server
Both Series 700 and Series 800 systems can be used as cluster servers.
Only Series 700 systems can be used as cluster clients.
When a Series 700 client is installed on a Series 700 server, the client can
use the same system software as the server. For convenience in
establishing software links and consistency in file system layout, this
shared root is placed in the /export/shared_roots directory using the
name /export/shared_roots/OS_700 as a symbolic link to /. All Series
700 clients in this cluster can use this shared root.
On a Series 800 server, however, a Series 700 client requires different
operating system software from the server. Therefore, a copy of the
Series 700 root file system and operating system must be installed in the
/export/shared_roots directory of the Series 800 system. This
procedure is called an alternate root installation. Typically, the Series
700 shared root is installed at /export/shared_roots/OS_700, but any
name can be used.
To perform an alternate root installation of Series 700 system software
on a Series 800 server:
Step 1. Run SAM on the cluster server:
sam
Step 2. From the “SAM Areas” screen, select “Clusters”.
Step 3. From the “SAM Areas:Clusters” screen, select “NFS Cluster
Configuration”.
Step 4. From the “Actions” menu on the “NFS Cluster Configuration” screen,
choose “Install OS for Clients”.
Step 5. Enter the name of the alternate root to be created.
/export/shared_roots/OS_700 is a good choice because it follows the
convention used on Series 700 servers. However, you may enter any
suitable name in the form /export/shared_roots/ shared_root_name .
Step 6. SAM invokes swinstall (see swinstall (1M)) with the necessary
parameters and the system proceeds with the alternate root installation.
