You must first remove HDLM before updating the kernel package, and
then re-install it after the update. Note that removing and re-installing
HDLM might change the correspondence between HDLM devices and
SCSI devices.
• To update the kernel package in an environment that satisfies the
following conditions, you need to change the Persistent Binding setting:

The host is in a Hitachi Compute Blade environment.
¢
The boot disk is managed by HDLM.
¢
The Persistent Binding functionality is enabled.
For details about the Persistent Binding setting, see the manual Hitachi

• If you use HDLM on a boot disk, LUKS cannot be used for the swap
partitions.
• The created LVM configuration does not change even if you perform an
upgrade installation of HDLM.
