CRS Installation

Installer also adds entries to the /etc/init.d as shown below. The main init scripts help to spawn processes required for cluster ready services functioning.

[root@node2 rc.d]# cd /etc/init.d
[root@node2 init.d]# ls -lt | head
total 384
-rwxr-xr-x    1 root     root          763 Jan 27 17:28 init.crs
-rwxr-xr-x    1 root     root         2261 Jan 27 17:28 init.crsd
-rwxr-xr-x    1 root     root         5950 Jan 27 17:28 init.cssd
-rwxr-xr-x    1 root     root         2280 Jan 27 17:28 init.evmd 

The /etc/inittab.crs file controls and describes the INIT processes for the CRS. The details are shown next:

[root@node2 etc]# more /etc/inittab.crs
#
# inittab       This file describes how the INIT process should set up
#               the system in a certain run-level.

# Default runlevel. The runlevels used by RHS are:
# 0 - halt (Do NOT set initdefault to this)
# 1 - Single user mode
# 2 - Multiuser, without NFS (The same as 3,if you do not have networking)
