16. Specify the settings required for using virtual environments.
If you are using Xen, set up Xen to use HDLM devices in domainU. If you
are using KVM, register HDLM devices into the hardware configuration
file.
For details on operating environments for the virtual environments
supported by HDLM, see
Virtual Environments Supported by HDLM on
page 3-92. For details on how to set up a virtual environment, see
Settings for Xen on page 3-180 or Settings for KVM on page 3-182.
17. Specify the settings required for operations in a cluster configuration.
For a cluster configuration, change the logical device file names of SCSI
devices specified in the cluster to logical device file names of HDLM
devices.
For details on setting the cluster software, see
Settings for Heartbeat on
page 3-183, Settings for Oracle RAC on page 3-183, Settings for the
RHCM on page 3-186, or Settings for VCS on page 3-188.
Disk Replication OS Installation
This subsection explains how to use the Master Image Deployment
functionality of Hitachi Compute Systems Manager (Compute Systems
Manager) or the disk replication functionality of Deployment Manager to
replicate an environment to which HDLM has been installed. Also, see the
Compute Systems Manager manual as necessary.
This method can be used in the following environment:
• Red Hat Enterprise Linux 5
• Red Hat Enterprise Linux 6
Important
When creating a disk image file on the replication-source host, be sure to
reduce the number of LUs recognized by the replication-source host to 256 or
less. You can increase the number of LUs to the maximum number of LUs
that can be supported by HDLM on the replication-destination host after
distributing the disk image file to the replication-destination host.
For Red Hat Enterprise Linux 5 (using LABEL for the kernel parameter)
The following procedure shows how to use LABEL for the kernel parameter for
Red Hat Enterprise Linux 5:
1. Back up the replication-source host.
Use the System-level Backup functionality of Compute Systems Manager
or Deployment Manager to back up the replication-source host so that
you can restore the replication-source host after replication or in the
event that an installation error occurs for the disk replication OS.
