These panel descriptions apply
to all virtual disk (VDisk) panels
that are part of the SAN Volume Controller Console.
Filtering VDisks
Use the Filtering
VDisk panel in the SAN Volume Controller Console to
specify filter criteria to limit the number of virtual disks (VDisks)
that
are displayed.
Creating a virtual disk
You can create virtual disks (VDisks) using the Create
Virtual Disk wizard in the SAN Volume Controller Console.
The Create Virtual Disk wizard guides you through the process of creating
a VDisk.
Creating VDisks to use as FlashCopy target
You can create virtual disks (VDisks) to be used as FlashCopy® mapping target VDisks
by using the Creating FlashCopy Target
VDisks wizard in the SAN Volume Controller Console.
The Creating FlashCopy Target
VDisks wizard guides you through the process of creating a target
VDisk.
Creating an image mode virtual disk
The Create
an Image Mode VDisk wizard helps you create an image
mode virtual disk (VDisk). Image mode VDisks are
VDisks that have a direct relationship with one MDisk. When you create
an
image mode VDisk, a direct mapping is made between extents that are
on the
MDisk and extents that are on the VDisk.
Adding a copy to VDisk
Use the Add Copy to
VDisk panel in the SAN Volume Controller Console to
add a copy to the selected virtual disk (VDisk). Each VDisk can
have a maximum of two copies.
Splitting a copy from a VDisk
Use
the Split a Copy from VDisk panel in the SAN Volume Controller Console to
create a separate VDisk from a synchronized VDisk copy.
Modifying virtual disks
Use the Modifying Virtual Disks panel in the SAN Volume Controller Console to
change the attributes of a selected virtual disk (VDisk).
Confirming modifying the VDisk
Use the Confirming Modifying the VDisk panel in the SAN Volume Controller Console to
confirm
the changes that you have made to the I/O group for the VDisk. Modifying
the
I/O group without first quiescing the I/O causes the I/O to fail.
If the VDisk
is mapped to a host, this will negatively affect the host.
Deleting a VDisk
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.
Confirming the forced deletion of a virtual disk (VDisk)
Use the Forced Delete of
a VDisk panel in the SAN Volume Controller Console to
confirm
that the VDisk that you selected is the one to delete. When you force
the
deletion of a VDisk, any host-to-VDisk mappings and any Copy Services
mappings
for this VDisk are deleted.
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.
Expanding virtual disks
You can expand the capacity of a virtual disk
(VDisk) from
the Expanding Virtual Disks panel in the SAN Volume Controller Console.
You can use this capability to change the size of a target or secondary
virtual disk (VDisk).
Shrinking virtual disks
You can shrink a virtual disk (VDisk) from
the Shrinking
Virtual Disks panel in the SAN Volume Controller Console.
Shrinking a VDisk reduces its total capacity. Use this function when
you want a FlashCopy target
disk to have the same capacity as its source. However, if the VDisk
contains data, do not shrink the size of the disk.
Shrinking or expanding space-efficient VDisks
Use the Shrink/Expand
Space-Efficient Disks panel in the SAN Volume Controller Console to
increase or decrease the real capacity of a space-efficient virtual
disk (VDisk).
Repairing space-efficient VDisks
Use the Repairing Space-Efficient VDisk panel
in the SAN Volume Controller Console to
repair the metadata on a space-efficient virtual disk (VDisk). The
operation
automatically detects corrupted metadata and performs any necessary
repair
actions.
Verifying VDisk copies
Use the
Verifying VDisk Copies panel in the SAN Volume Controller Console to
start the virtual disk (VDisk) copy verification process for a selected
VDisk
copy. The VDisk copy verification process checks if data on the copies
matches
the data on the primary VDisk. You can select actions that the SAN Volume Controller Console
to takes if differences are found during verification.
Recovering VDisk
Use the Recover VDisk panel in
the SAN Volume Controller Console to
recover virtual disks (VDisks) that have lost cached data or space-efficient
metadata, usually as a result of hardware failure. A Fast Write State
of Corrupt indicates this data loss.
Recovering all VDisks
Use the Recover
All VDisks panel in the SAN Volume Controller Console to
recover all VDisks or copies in the cluster that have lost cached
data or space-efficient metadata, usually as a result of a hardware
failure. A Fast Write State of Corrupt indicates this data loss.
VDisk recovery results
Use
the VDisk Recovery Results panel in the SAN Volume Controller Console to
view the results of a virtual disk (VDisk) recovery operation.
Migrating to an image mode virtual disk
You can migrate all the data that is associated with any
type of virtual disk (VDisk) to an image mode VDisk using the Migrate
to an Image Mode VDisk wizard.
Migrating virtual disks
You can migrate a VDisk copy from
one MDisk group to another from the Migrate Virtual Disks panel in
the SAN Volume Controller Console.
Viewing VDisks
Use the Viewing VDisk panel in the SAN Volume Controller Console to
display all the virtual disks (VDisks) that belong to a cluster.
Viewing VDisk general details
You can view detailed information about a virtual disk
(VDisk) from the View VDisk Details panel in the SAN Volume Controller Console.
Viewing VDisk copy details
Use the View
VDisk Copy Details panel in the SAN Volume Controller Console to
display information about the copies that are associated with a selected
virtual
disks (VDisk).
Viewing FlashCopy mapping details
Use the Viewing FlashCopy Mapping Details panel in the SAN Volume Controller Console to view information that is associated with a specific FlashCopy mapping.
Viewing VDisk Copy Services details
Use the View VDisk Copy Services
Details panel in the SAN Volume Controller Console to
view details about the FlashCopy relationships and
Metro Mirror or Global Mirror relationships that the selected VDisk
is a part of.
Viewing dependant FlashCopy mappings for VDisk
Use the Viewing dependant FlashCopy mappings for VDisk panel in the SAN Volume Controller Console to display FlashCopy mappings that have target VDisks that are dependent upon data held on the specified VDisk. This information can be used to determine whether a FlashCopy mapping can be prepared.
Viewing FlashCopy mappings that must stop before VDisk deletion
Use the Viewing FlashCopy mappings
that must stop before VDisk deletion panel in the SAN Volume Controller Console to
display a list of FlashCopy mappings that must be stopped before deleting
a virtual disk (VDisk).
Viewing valid VDisk copies
Use the Viewing Valid VDisk Copies panel in the SAN Volume Controller Console to
display all mappings that has target virtual disk (VDisk) with a valid
copy of the specified VDisk. The mappings that are returned are in
either the Copying state or in the Stopping or Idle
or Copied states with 100% progress.
