Removing the Mirror Relationship Between Two Virtual Disks

Use the Remove Mirror Relationship option to remove the mirror relationship between the two  in a . Perform the following steps:

Important:

• This option is not available unless there are defined mirror relationships on the .
• This option does not delete the , , or the  that support mirroring for the storage arrays. Data on the virtual disks is not affected. As a result of this operation, the primary virtual disk and secondary virtual disk become standard, -accessible, non-mirrored virtual disks.
• This option is only available for the local virtual disk (primary or secondary) that is present in the storage array you are currently managing. This option is not available if you select a remote secondary virtual disk in the Logical View.
• The mirror relationship is first removed on the local storage array and then on the remote storage array. If the mirror relationship is successfully removed on the local storage array but cannot be removed on the remote storage array because of a communication problem, then an error message is displayed. The error message shows the name of the remote storage array with the orphaned mirrored virtual disk, and the name of the virtual disk. Open the Array Management Window for the remote storage array, select the specified virtual disk, and remove the mirror relationship.
  • If the mirror relationship was successfully removed on the secondary side, but not the primary side, then the first I/O write to the primary virtual disk causes the mirror state to go . The Logical View of the primary Array Management Window also then shows an Unresponsive remote secondary virtual disk, represented by the icon . Remove the mirror relationship on the primary storage array to correct the problem.
  • If the mirror relationship was successfully removed on the primary side but not on the secondary side, then typically there is not a change to the representation of the secondary virtual disk in the secondary Logical View in the Array Management Window. Remove the mirror relationship on the secondary storage array to correct the problem and make the virtual disk accessible by hosts.

Example

The example of the previous Logical View shows a defined Remote Virtual Disk Mirror consisting of the primary virtual disk Accounting and the secondary virtual disk Accounting2.

After using the Remove Mirror Relationship option, the virtual disk Accounting is displayed as a standard, non-mirrored virtual disk in the Logical View. As shown in the preceding graphic, the (former) secondary virtual disk Accounting 2, from a remote storage array, is no longer displayed.
