If you are using Red Hat Enterprise Linux AS4/ES4, Oracle Enterprise Linux 4,
Oracle Enterprise Linux 5, Oracle Unbreakable Enterprise Kernel 5, Oracle
Unbreakable Enterprise Kernel 6, or SUSE LINUX Enterprise Server, you must
remove HDLM before updating a kernel package or applying an OS update
package.
After HDLM is removed, the mappings between HDLM devices and LDEV
information are not inherited even if you reinstall HDLM. The procedures
provided here assume that you want the mappings between HDLM devices
and LDEV information inherited.
If the mappings between HDLM devices and LDEV information do not need to
be inherited, the procedures provided here are unnecessary. Remove HDLM
by following the procedure in
Removing HDLM on page 3-223, and then
update the kernel package or apply the OS update package. Afterwards,
follow the procedure in
Installing HDLM on page 3-101 to install HDLM again.
When you are not using the HDLM device as a boot disk
To update a kernel package or apply an OS update package when an
HDLM device is not used as the boot disk:
1. Copy the following files into a directory:
¢
/etc/opt/DynamicLinkManager/.dlmfdrv.conf
¢
/etc/opt/DynamicLinkManager/.dlmfdrv.unconf
#
#
If this file does not exist, you do not have to copy it into a directory.
2. Remove HDLM.
