Editing virtualization management settings

This section explains how to edit virtualization management settings.

 If the setting of the LDEV virtualization management is canceled, Transient is displayed in the Virtual LDEV ID, and Failed is displayed on the Status column of the Task window. To resolve the transient status, perform one of the following operations to LDEVs:

• Resolve the cause of the failure by addressing the solution of the error message in the Task window. Then retry the same operation by using the Edit Virtualization Management Settings window.

• In the Edit Virtualization Management Settings window, set Virtual Management Settings to Disable and apply the setting to the storage system.

Prerequisite information

• The Security Administrator (View & Modify) role is required.

Procedure

1. In the Administration tree, select Resource Groups.

2. Select the resource group that has the volume whose virtualization management settings you want to edit.

3. In the LDEVs tab, select a volume whose virtualization management settings you want to edit.

4. Use either of the following methods to display the Edit Virtualization Management Settings window.

• Click Edit Virtualization Management Settings.

• In the Settings menu, select Resource Management, and then Edit Virtualization Management Settings.

5. In Virtualization Management Settings, select one or more of the following virtualization management settings.

• Enable: Virtualization management can be used. You can set a initial virtual LDEV ID or the virtual configuration, or both.

• Enable (Not Set): Virtualization management can be used. However, you cannot set the initial virtual LDEV ID and the virtual configuration.

• Disable: Virtual management cannot be used.

6. If you select Enable in Virtualization Management Settings and can set a virtual LDEV ID, set the starting virtual LDEV ID for Initial Virtual LDEV ID.

A virtual LDEV ID that is not used in the virtual storage machine is assigned at the interval specified in Interval, sequentially starting from the specified virtual LDEV ID.

 If the virtual storage machine is the same as the storage system, assign the virtual LDEV ID which is different from the LDEV ID of the selected LDEV. If the virtual storage machine is the same as the storage system, and if the virtual LDEV ID which is the same as LDEV ID of the selected LDEV must be assigned, select Disable in Virtualization Management Settings.

 If the virtual storage machine is configured by multiple storage systems, a virtual LDEV ID that is already used in another storage system might be assigned. In such a configuration, set the interval so that a virtual LDEV ID that is already used in another storage system is not assigned.

7. If you select Enable in Virtualization Management Settings, select Virtual Configuration.

If you want to specify the virtual configuration of the LDEV (to make the configuration different from that of the LDEV), select Specify.

If you do not want to specify the virtual configuration of the LDEV (to make the configuration the same as that of the LDEV), select Not Set.

1. In Emulation Type, select the virtual emulation type.

For the virtual emulation type, like the emulation type, set one of the emulation types that exist in the same group of 32 volumes with LDEV IDs.

2. Select CVS Settings.

3. In Number of Concatenated LDEVs, specify the number of concatenated virtual LDEVs with a value from 1 to 36 (decimal number).

If you do not concatenate virtual LDEVs, enter 1.

4. In SSID, specify a virtual SSID with a value from 0004 to FFFE (hexadecimal number).

Set a virtual SSID for each virtual LDEV address (64, 128, 256) in the virtual storage machine.

 For the virtual configuration, the specified values are set for all selected LDEVs.

8. Click Finish.

9. Enter the task name in Task Name.

10. Click Apply.

The task is registered, and if the Go to tasks window for status check box is selected, the Tasks window appears.
