Disk device decommissioning
25
Provided that the crypto configuration is not left uncommitted because of any crypto configuration
changes or a failed device decommission operation issued on a encryption Group Leader node,
this error message will not be seen for any device decommission operation issued serially on an
encryption group member node. If more than one device decommission operation is attempted in
an encryption group from member nodes simultaneously, this error message is transient and will
go away after device decommission operation is complete. If the device decommissioning
operation fails, retry the operation after some time has passed.
With the introduction of Fabric OS 7.1.0, all key vault types support the ability to decommission disk
LUNs. For earlier Fabric OS versions, (for example, Fabric OS 7.0.x) the command that is used to
decommission LUNs is only recognized on DPM (formerly RKM) and LKM/SSKM key vault types.
Decommissioning disk LUNs
Use the following procedure to decommission a disk LUN.
1. Select Configure > Encryption from the menu task bar to display the Encryption Center
dialog box. (Refer to Figure 303 on page 852.)
2. Select a group, switch, or engine from the Encryption Center Devices table that contains the
storage device to be configured, then select Group/Switch/Engine > Targets from the menu
task bar.
NOTE
You can also select a group, switch, or engine from the Encryption Center Devices table, then
click the Targets icon.
The Encryption Targets dialog box displays. (Refer to Figure 426 on page 994.)
3. Select a Target storage device from the list, then click LUNs.
The Encryption Target Disk LUNs dialog box displays.
4. Select the LUNs associated with the device, then click Decommission.
A warning message displays.
5. Click Yes to proceed with the decommissioning process.
A LUN Decommission Status dialog box is displayed while the LUNs are being
decommissioned. Click OK to close the dialog box.
If a rekey operation is currently in progress on a selected LUN, a message is displayed that
gives you a choice of doing a Forced Decommission, or to Cancel and try later after the rekey
operation is complete.
6. To check on the progress of the decommissioning operation, click Refresh. When
decommissioning is complete, the LUNs are removed from the Encryption Target LUNs table.
