Use the Deleting a VDisk panel in the SAN Volume Controller Console to
delete a virtual disk (VDisk) from the cluster. After a VDisk is deleted,
all of the data on the VDisk is lost. Therefore, ensure that the data
on the VDisk is no longer required before you delete the VDisk.
Introduction
If
there are mappings between this VDisk and a host, you cannot delete
the VDisk unless you specify the Force option.
Attributes
VDisks are logical disks that are
created from the extents of MDisks. Only MDisks that are in the same
MDisk group can contribute extents to a VDisk.
The
following attributes are displayed in the table:
- Name
- Displays the name of the VDisk.
- State
- Displays the current state of the VDisk. The following values
are possible:
- Offline
- Indicates that the VDisk is unavailable. One or more of the managed
disks (MDisks) that make up the VDisk are degraded or offline and
consequently the VDisk is unavailable.
- Online
- Indicates that the VDisk is available. All the MDisks that make
up the VDisk are available.
- Degraded
- Indicates that the status of the VDisk is degraded if the VDisk
is online to one node and offline to the other node or if the VDisk
is online to one node and the other node is missing.
- I/O Group Name
- Displays the name of the I/O group that contains this VDisk.
- MDisk Group Name
- Displays the name of the MDisk group that contains this VDisk.
- Capacity
- Displays the size, in megabytes, of the VDisk.
- Type
- Displays the VDisk type. The following values are possible:
- Striped
- Indicates that the VDisk 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 was created from one MDisk that is in
the MDisk group. Extents are sequentially allocated on the MDisk.
- Image
- Indicates that the VDisk was created from one MDisk that is in
the MDisk group. Provides a direct block-for-block translation from
the MDisk to the VDisk. Intended for MDisks that already contain data
that was not written through the SAN Volume Controller.
- Hosts
- Displays if the selected VDisk is mapped to the host. The following
values are possible:
- Mapped
- Indicates that the VDisk is mapped to a host. If host mappings
exist for the virtual disk, or if any FlashCopy mappings would be
affected, the deletion fails. You can use the Force delete option
to force the deletion. If you use the Force delete option,
mappings that have the virtual disk as source or target are deleted,
other mappings in a cascade might be stopped, and then the virtual
disk is deleted. The Force delete option also
deletes any Metro Mirror or Global Mirror relationships that exist
for the specified VDisk.
- –
- Indicates that the VDisk is not mapped to a host.
- FlashCopy®
- Displays the number of FlashCopy mappings that this
VDisk belongs to.
- Relationship Name
- Displays the name of Metro Mirror or Global Mirror mappings that
this VDisk belongs to.
- Relationship Name
- Displays the name of Metro Mirror or Global Mirror
mappings that this VDisk belongs to.
- Copies
- Displays the number of mirrored copies associated with the selected
VDisk.
Note: When a VDisk is deleted, all mirrored copies are also
deleted.
Fields
The
following fields are available:
- Force delete
- Select this to force the deletion of a copy.
Actions
The
following actions are available:
- OK
- Click this button to delete the selected VDisk.
- Cancel
- Click this button to exit the panel without deleting a VDisk.
