Set up the volume type for a device that is connected to the Storage Server.
The setting of the operation type is explained below. This involves:
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 | 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 GUI operations or commands. For information on the operation method using GUI, refer to "Define the Role of a Volume" in the "ETERNUS SF AdvancedCopy Manager GUI User's Guide".
For information on the operation method using commands, refer to swstdevinfoset (Device information setting command).
Note
In order to set up a volume as a transaction volume, there are some points which should be taken into consideration. For more details, see "12.1.1 General notes".
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 4.4.5 Fetching device information on a Storage Server.
Register the information by executing swstdevinfoset (device information 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 assigned device to a drive letter or mount point cannot be configured as a backup volume. But, It is only possible to configure it as a transaction volume.
Logical Units (disks) cannot be set for a transaction volume or a backup volume.
Point
You can check the volumes that have been registered as follows:
Using the GUI client to check volumes
Transaction volume information or back up volume information can be referred to from the GUI client. For details, refer to the "ETERNUS SF AdvancedCopy Manager GUI User's Guide."
Checking by executing a Command at the Command line.
You can view information for a registered transaction volume or backup volume. Refer to "swstdevdisp (Device usage status display command)"
