Deleting a device
About this task
You may delete one or more top-level devices that do not have virtual volumes. If the device's children are other devices, the
child devices become top-level devices. If the device's children are extents, the status of those extents change from Used to
Claimed.
Steps
1. From the GUI main menu, do one of the following:
a. In a metro node Local:
i. Select Provision Storage.
ii. In the View by drop-down, select Devices.
b. In a metro node Metro:
i. Select Provision Storage.
ii. In the Provision on drop-down, select the cluster of the devices.
iii. In the View by drop-down, select Devices.
2. In the Devices view, click Delete.
3. Review the devices to delete, and then click OK.
4. Review the results, and then click Close. You can sort the results.
If the device had child devices, the dialog box also displays the child devices have now become top-level devices.
Mirroring a device
About this task
You can mirror a device locally or remotely. When you add a local mirror, a device in the local cluster is used to create a RAID-1
device. If the local device you are mirroring is already a RAID-1, the mirror is added as another leg. For a remote mirror, a device
in the remote cluster is used to create a distributed device. You can mirror a device with or without a volume on top.
NOTE: When creating a remote mirror, the mirror must not be in a consistency group.
Steps
1. From the GUI main menu, do one of the following:
a. In a metro node Local:
i. Select Provision Storage.
ii. In the View by drop-down, select Devices.
b. In a metro node Metro:
i. Select Provision Storage.
ii. In the Provision on drop-down, select the cluster of the devices.
iii. In the View by drop-down, select Devices.
2. In the Devices view:
● To add a local mirror, select MORE > Add Local Mirror. The Add Local Mirror wizard opens.
● To add a remote mirror, select MORE > Add Remote Mirror. The Add Remote Mirror wizard opens.
3. Follow the instructions on the wizard screens. For additional help on any wizard screen, click Help.
Device status
The following tables define the Health, Operational, and Service status for devices.
Health status
Description
OK The device is functioning normally.
Degraded The device may be out-of-date compared to its mirror. (This state applies only to
devices that are part of a RAID-1 device.)
