In order to configure mirroring for disks other than the system disk, use the following methods.
Using Automatic Configuration Wizard
Using the [Settings] menu
For details on operation using the [Settings] menu, see "Operating from the Settings Menu."
Automatic Configuration Wizard allows you to create a volume by simply clicking <Next>.
In order to ensure an environment which allows an application to continuously access data at the time of I/O adapter, controller or cable failure, Automatic Configuration Wizard mirrors disks connected to different I/O adapters.
When there is an add-on expansion mechanism within the expansion unit (add-on file unit or add-on disk cabinet), expansion units are mirrored.
In order to ensure a safe mirroring environment, Automatic Configuration Wizard automatically creates one spare disk for every ten disks. For automatic configuration, make sure you have a minimum of three disks.
Supported Disks
Disks that can be configured for mirroring with the Automatic Configuration Wizard are those disks whose physical disk names are in "cXtXdX" format. If all target disks are connected to one I/O adaptor, the Automatic Configuration Wizard cannot be used. There, perform configuration from the relevant configuration screen.
Mirroring Expansion Units with Add-On Expansion Mechanism
When you are mirroring expansion units with add-on expansion mechanism, connect the two cables connected to the same expansion unit to the same I/O adapter on the processing unit.
Shared Disk Mirroring
Shared disks in cluster system cannot be mirrored using the automatic configuration feature. Set the configuration from the [Settings] menu.
System Disk Mirroring
System disk cannot be configured automatically. Instead, select [System Disk Settings] in the [Settings] menu.
To start Automatic Configuration Wizard, select [Automatic Configuration] in the [Settings] menu.
Set the configuration environment in order to create a volume using the Automatic Configuration Wizard.
Selecting the [Class Name]
If you clicked <New> in the [Class Name] list, a new class will be created for the volume. If you are creating a volume within an existing class, select the appropriate class from the list. If no classes have been created, the only option available on the list will be <New>.
Selecting the [Spare Disk]
When creating a spare disk from the selected disk, select [Create a spare disk]. If a spare disk is unnecessary, select [Do not create a spare disk].
Click <Next>, and the message below appears.
Disks available for mirroring appear in [Selected Disk] field.
If there are disks you do not want to mirror, select the disk by clicking the icon, and click <Delete>. If there are disks you want to mirror in [Candidate Disk] field, select the disk by clicking the icon, and click <Add>.
When moving all disks in [Candidate Disk] field to [Selected Disk] field, click <Add All>.
When moving all disks in [Selected Disk] field to [Candidate Disk] field, click <Delete All>.
Click <Next>, and the message below appears.
GDS will automatically combine the disks selected in the previous screen and create a volume.
Volume name and its disk configuration, and the disk defined as spare disk will appear.
Click <Create> to continue.
Confirm that the volume creation was successful, and click <Exit>.
Volume information and disk information created using the Automatic Configuration Wizard will appear on the Main screen.
