Deleting a copy from a VDisk

Use the Deleting a Copy from VDisk panel in the SAN Volume Controller Console to delete a mirrored copy from the selected virtual disk (VDisk). If the VDisk that you are creating uses Solid State Drives (SSDs) that reside inside the node, then the data that is stored on the VDisk is not protected against SSD or node failures. To avoid data loss, add a VDisk copy that uses SSDs inside another node.

Attributes

The following attributes are displayed in the table:
Select
Allows you to select the VDisk copy to delete.
Copy ID
Displays the system-assigned identifier for the mirrored copy of the selected VDisk.
Status
Displays the current status of a mirrored copy of the selected VDisk. The following values are possible:
Offline
Indicates that the copy is unavailable. One or more of the managed disks (MDisks) that make up the VDisk are degraded or offline and consequently the VDisk copy is unavailable.
Online
Indicates that the copy is available. All the MDisks that make up the VDisk copy are available.
Synchronize
Displays if the VDisk copies are synchronized. The following values are possible:
Yes
Indicates that the VDisk copies are synchronized.
No
Indicates that the VDisk copies are not synchronized.
Primary
Indicates if the VDisk copy is the primary copy.
MDisk Group ID
Displays the system-assigned identifier for the managed disk (MDisk) group associated with the VDisk copy.
MDisk Group Name
Displays the name of the MDisk group associated with the VDisk copy.
Type
Displays the type of VDisk copy. The following values are possible:
Striped
Indicates that the VDisk copy was created from multiple MDisks that are in the MDisk group. Extents are allocated on the MDisks in the specified order.
Sequential
Indicates that the VDisk copy was created from one MDisk that is in the MDisk group. Extents are sequentially allocated on the MDisk.
Image
Indicates that the VDisk copy was created from one MDisk.
Used Capacity
Displays the amount of space that has been used by the VDisk copy.
Real Capacity
Displays the real size of a VDisk copy. This capacity is displayed in a percentage.
Free Capacity
Displays the amount of space that is available to the VDisk copy.

Fields

The following field can be updated:

Force delete
Select this to force the deletion of the VDisk copy. To complete the deletion process for a selected mirrored VDisk copy, use the Force delete option to force the deletion in the following situations:
  • Migration to an image mode VDisk is in progress for the selected VDisk copy.
  • If the selected VDisk copy is an image mode with virtual medium errors.
  • The cache is not empty for an image mode VDisk copy.
  • The image mode VDisk copy is not synchronized.
  • If the copy being deleted is the last synchronized VDisk copy, the VDisk and all its copies are deleted.

Actions

The following actions are available:

OK
Click this button to delete the selected VDisk copy.
Cancel
Click this button to exit the panel without deleting the selected VDisk copy.
