3. Creating an HDLM Environment
However, you can avoid the above situations by setting a permanent target ID for
each LU with the HBA driver persistent binding functionality. For details on
whether the persistent binding functionality is supported for your HBA driver and
the setting method, see the manual provided with the HDLM driver.
If you created an environment by using the QLogic HBA driver while SUSE
LINUX Enterprise Server 9 is being used, before installing HDLM, make sure
that the following coding is in the line for
sysconfig/kernel
• When using the QLA22XX HBA:
qla2200
• When using the QLA23XX HBA:
qla2300
If xxx is appears in the file instead of
qla2
qla2xxx
INITRD_MODULES="mptscsih qla2300 reiserfs"

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
is updated, the OS is restarted, and no HDLM information exists in the
rc.d/rc.sysinit
