The above execution results indicate that one storage system and one LU
in a two-path configuration are recognized.
Note that you can remove the backup file created in step 1 if you are no
longer going to use the file.
For Red Hat Enterprise Linux 6 (using UUID for the kernel parameter)
The following procedure shows how to use UUID for the kernel parameter for
Red Hat Enterprise Linux 6:
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 the replication or in the
event that an installation error occurs for the disk replication OS.
2. Check the HDLM devices specified in the /etc/fstab file on the
replication-source host.
To create a disk image of the replication-source host, change the
description of the HDLM devices so that the disk image uses UUID.
The following is an example of the /etc/fstab file in which HDLM devices
are specified:
:
/dev/sddlmaa1 /boot ext4 defaults 1 2
:
/dev/sddlmaa3 swap swap defaults 0 0
:
3. Verify that UUID shows the HDLM devices on the replication-source host.
An example of executing the command is as follows:
# /sbin/blkid -c /dev/null /dev/sddlmaa1
/dev/sddlmaa1: UUID="a136da75-c151-472d-ac5c-20f165f93776"
TYPE="ext4"
Verify that UUID shows a136da75-c151-472d-ac5c-20f165f93776.
The following is an output example when the UUID setting is not
configured.
When the partition type is not swap and the file system type is ext4:
# /sbin/blkid -c /dev/null /dev/sddlmaa1
/dev/sddlmaa1: TYPE="ext4"
When the partition type is swap:
