If qla2xxx is appears in the file instead of qla2200 or qla2300, change
qla2xxx to qla2200 or qla2300 as follows:

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
dlmupdatesysinit
Utility for Updating System Scripts on page 7-39 .
• 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:
