Task 3: Making Initial Host Settings
After the packages and configuration file are installed, the Host is ready to accept
multipath settings.
Setting the Daemon to Run
RHEL 5.3, 5.4, 5.5
This action requires RHEL installation with the “linux mpath” Option. See “Before
You Begin” on page 385.
To set the MP daemon to run at boot time:
1. Open a terminal window.
2. Verify that /etc/rc.d/rc[3~5].d/ has a symbolic link to
/etc/rc.d/init.d/multipathd. Also see the Note below.
Run the command:
# ls -al /etc/rc.d/rc[3~5].d/ | grep multipathd
3. If there is no symbolic link, run the command:
# cd /etc/rc.d/rc[3~5].d/
Then run the command:
# ln -s /etc/rc.d/init.d/multipathd S13multipathd
Note: /etc/rc.d/rc[3~5].d saves a link to start at each run level.
• Run level 3 is for a single user.
• Run level 4 is for multiple users.
• Run level 5 is for multiple users on X Windows.
