Editing virtualization management settings

You can edit the virtualization management settings of volumes to enable and disable virtualization management, set the virtual LDEV ID, and specify the virtual configuration (emulation type, CVS settings, and SSID).

Caution

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 in the Task window. To resolve the transient status, perform one of the following operation on the LDEVs:

  • Resolve the cause of the failure by addressing the error message in the Task window, and 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 before applying the setting to the storage system.

Before you begin

You must have Security Administrator (View & Modify) role to perform this task.

Procedure

  1. In the Administration tree, select Resource Groups.

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

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

  4. Click Edit Virtualization Management Settings.

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

    • Enable: Virtualization management can be used. You can set an 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 or 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.
    NoteIf the virtual storage machine is the same as the storage system, assign a virtual LDEV ID that is different from the LDEV ID of the selected LDEV. If the virtual storage machine is the same as the storage system and you need to assign a virtual LDEV ID that is the same as the LDEV ID of the selected LDEV, select Disable in Virtualization Management Settings.
    CautionIf 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, which is similar to the emulation type, set one of the emulation types that exists 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.

      Note

      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.

    The virtual storage machine is the unit that is used to manage virtualized resources for each storage system. For software with global storage virtualization functions (for example, global-active device, nondisruptive migration), a virtual storage machine is created in the storage system.
