NFS Cluster Client on Solaris
In addition to the general rule for determining cluster clients described
in the section “Installation Tips for UNIX Managed Nodes” on page 50
there is also one specific rule for Solaris:
Solaris cluster clients (both with and without disks) are those Solaris
systems that have either a
/usr
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 local
/opt
to
/opt
of the cluster server:
mount <cluster_server>:/opt /opt
The ITO Default Operator on Solaris
The ITO default operator, opc_op, owns
/home/opc_op
as home
directory. By default, the operator uses the Bourne Shell (
/bin/sh
) and
is locked until the
passwd(1M)
command is executed. User opc_op
belongs to the group opcgrp.
Currently, user opc_op and group opcgrp are only added locally on the
managed node (useradd or groupadd are used). If the managed node is
a Network-Information-Service (NIS or NIS+) client, the ITO
installation checks if user opc_op is already in the NIS database. If so, no
additional user is installed, otherwise, opc_op is added only locally on the
managed node.
Solaris System Resources Adapted by ITO
ITO makes changes in the following system resource files:
❏
/etc/passwd
and
/etc/shadow
- entry for the default ITO operator
❏
/etc/group
- group entry for the default ITO operator
❏
/etc/init.d/opcagt
- ITO startup/shutdown script
❏
/etc/rc3.d/S99opcagt
- file created
❏
/etc/rc0.d/K09opcagt
- file created
❏
/etc/rc1.d/K09opcagt
- file created
❏
/etc/vfstab
- on cluster client only; entry for mount
/opt
directory
❏
/etc/init.d/ncs
- NCS startup script (if not already present)
