Specifying the primary path for an array or disk
When an array is configured for Fail Over Only (Active/Passive) operation, you can specify the path that is used for data transfer. The specified path, called the primary path, is the only path used for data transfer.
To specify the primary path for an array or disk
- The Set primary path screen appears.
Display the Set primary path screen by doing the following:
Make sure the DMP DSMs tab is selected in the right pane.
To display the DMP DSMs tab, use the tree view in the left pane to select a disk under the DMP DSMs folder, or a disk under the Disks folder that has DMP DSMs enabled, and then click the DMP DSMs tab that appears in the right pane.
In the DMP DSMs tab, right-click on the path you want to be the primary path for the array, and select Set Primary Path from the path context menu.
- Select to set the primary path for the device or for the array, as follows:
Primary path for device
The primary path for the device is available only when the operational mode for the path to the disk is specified as Fail Over Only (Active/Passive) and the currently selected path is not the primary path. The primary path is the only path that is used to transfer data to and from the disk. Clicking this menu selection makes the selected path the primary path to the disk. The other paths to the disk are placed on standby and available for failover.
Primary path for array
This lets you specify the currently selected path as the primary path to the array. The primary path is the only path that is used to transfer data to and from the array.
The array's primary path can be set regardless of the array's current load balance setting. This means that if the load balance setting for the array is set to round robin (Active/Active) or other Active/Active load balance setting, then the primary path setting for the array is not used. However, if a disk in the array is set to Fail Over Only (Active/Passive), the primary path for the array becomes the primary path for the disk.
For example, if an array has a load balance setting of round robin (Active/Active) and the primary path for the array is set to path 2-1-1, then any disk in the array that has the load balance setting of Fail Over Only (Active/Passive) has its primary path set to path 2-1-1.
- Click OK to save your setting and exit the screen.
A blue checkmark icon identifies the primary path.
