Set up the volume type for a device that is connected to the Managed Server. The setting of the type is explained below.
Defining the volume to be backed up as a transaction volume.
Preparing backup volumes. Prepare the number of volumes shown below in accordance with the operation type, each volume having the same partition size as the transaction volume, and define them as backup volumes.
Backup method | Number of required backup volumes |
|---|---|
Snapshot fast backup | Number of backup generations |
Synchronized high-speed backup | Number of backup generations + 1 |
This process can be carried out using either Web Console or swstdevinfoset (Device information setting command).
Note
A logical volume of LVM cannot be registered as transaction volume or backup volume. Register it in a volume group.
In order to use a volume group as a transaction volume, it is necessary to create a logical disk as follows:
Do not register two or more physical disks into one volume group.
Create a logical disk so that one logical disk does not span two or more physical disks.
To change the configuration of a partition that has been registered as either a transaction volume or a backup volume, take the following steps:
Delete the registered configuration, and then change the configuration.
Attempt to "3.4.4 Fetching device information on a Managed Server".
Register the information by executing swstdevinfoset (Device information setting command).
The backup volume must be the same size (have the same number of bytes) as the transaction volume.
Backup and backup volumes are not supported for the system partition or the partition where AdvancedCopy Manager is installed.
The mounted device cannot be set to backup volume. However, it is possible to set it to the transaction volume.
When the registered contents are checked by the Web Console or by the command, the value displayed on the "Size" column is the physical disk size. When a volume group is registered, this column also displays the physical disk size of the volume group.
Point
The registered volumes can be confirmed using either Web Console or swstdevdisp (Device usage status display command).
