Hitachi Dynamic Link Manager Software Users Guide for Linux

¢
When using Red Hat Enterprise Linux AS4/ES4 or SUSE LINUX
Enterprise Server:
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
Gigabit Fibre Channel Board User's Guide.
• 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.
Overview of the Procedure for Installing HDLM in a Boot Disk
Environment
This subsection provides an overview of the procedure for installing HDLM in
a boot disk environment.
Settings for Using an HDLM Device or a Logical Volume (LVM2) on an HDLM
Device as a Boot Disk
This subsection provides an overview of how to perform a new installation of
HDLM in a boot disk environment that uses either a SCSI device or a logical
volume (LVM2) on a SCSI device. For details, see
Settings for a Multipath
Boot Disk Environment on page 3-142.
1. Install HDLM.
See step 1 to 3 in Settings for a Multipath Boot Disk Environment on page
3-142.
2. Edit the configuration file to change the definition such that the HDLM
device can be used as a boot disk.
After editing the configuration file, restart the host to activate the setting.
See steps 4 to 19 in
Settings for a Multipath Boot Disk Environment on
page 3-142.
After completing the above procedure, you can perform a new installation of
HDLM in a boot disk environment that uses a SCSI device or a logical volume
(LVM2) on a SCSI device.
