Notes on Linux

•

Install and uninstall HDLM in a multi-user mode environment.

•

Note that, if the /var directory is set up on a different partition than the

root directory (/), no logs will be output to the /var/log/messages file

until the /var directory has been mounted during the OS start process.

•

If multiple OSs exist on a disk that differs physically or logically within the

same host, HDLM can be installed on each OS. Also, if multiple kernels

exist on one OS, HDLM can be used only when the kernel installed with

HDLM is started.
Note, however, that if the OS is Red Hat Enterprise Linux 5 or Red Hat

Enterprise Linux 6, you can use HDLM even if HDLM is not installed in the

running kernel. In this case, no settings are required.

•

For Red Hat Enterprise Linux, if HDLM is installed, the initscripts

package is updated, the OS is restarted, and no HDLM information exists

in the /etc/rc.d/rc.sysinit file, execute the system script update

utility (dlmupdatesysinit).
Confirm that the HDLM information is missing by executing the following

commands:

# grep DLM /etc/rc.d/rc.sysinit

# grep DLM /etc/init.d/halt

If nothing is output after command execution, HDLM information is

missing.
For details about the dlmupdatesysinit utility, see

•

In an environment that uses SUSE LINUX Enterprise Server, after

upgrading the aaa_base, raidtools, mdadm, or lvm2 package after HDLM

installation and then restarting the OS, you must execute the
dlmupdatesysinit utility to update the system scripts if the following

conditions are satisfied:
