Enabling the virtualization management setting for LDEVs

Use this procedure to enable the virtualization management setting of volumes using Device Manager - Storage Navigator. When virtualization management is enabled for a volume, you can set the virtual LDEV ID and specify the virtual volume configuration of the volume.

Before you begin

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

Procedure

  1. In the Administration tree, select Resource Groups.

  2. Select the resource group that contains the target volume.

  3. In the LDEVs tab, select the target volume, and click Edit Virtualization Management Settings.

  4. In Virtualization Management Settings, select Enable or Enable (Not Set).

    • Enable: Virtualization management can be used. You can set the virtual LDEV ID and specify the virtual LDEV configuration using Device Manager - Storage Navigator.
    • Enable (Not Set): Virtualization management can be used, but you cannot set the virtual LDEV ID or specify the virtual LDEV configuration using Device Manager - Storage Navigator.
    • Disable: Virtualization management cannot be used for the selected volume.

  5. If you selected Enable in Virtualization Management Settings, set the virtual LDEV ID for the selected volume.

    If you selected more than one volume, set the starting virtual LDEV ID in Initial Virtual LDEV ID, and set the interval for the subsequent LDEV IDs in Interval. Virtual LDEV IDs that are not used in the virtual storage machine are assigned sequentially at the specified interval, 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 in 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.

  6. If you selected Enable in Virtualization Management Settings, select Virtual Configuration to specify the volume configuration information. For the virtual volume configuration, the specified values are set for all selected LDEVs.

    • If the volume configuration of the virtual LDEV and the LDEV are the same, select Not Set.
    • If the volume configuration of the virtual LDEV and the LDEV are different, select Specify, and then set the following parameters:

    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. If the virtual LDEV is a LUSE volume, in Number of Concatenated LDEVs specify the number of concatenated LDEVs (decimal number from 2 to 36).

      If the virtual LDEV is not a LUSE volume, enter 1.

    4. In SSID, specify the virtual SSID (hexadecimal number from 0004 to FFFE).

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

  7. Click Finish.

  8. Enter the task name in Task Name.

    If you want the Tasks window to open automatically, select Go to tasks window for status.

  9. Click Apply to register the task.

    Caution

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

    • Resolve the cause of the failure by addressing the error message in the Task window, and then retry the 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.
