This topic includes information
about managing your virtual disks.
Viewing the VDisk status
You must view the status of virtual disks (VDisks) as part
of the repair verification procedures.
Creating VDisks
You can create virtual disks (VDisks) using the Create
Virtual Disks wizard.
Creating VDisks for FlashCopy targets
You can select an existing source virtual disk (VDisk)
to use to create target VDisks for FlashCopy® mappings.
The Creating VDisk for use as FlashCopy Targets
wizard in the SAN Volume Controller Console lets
you create one or more source VDisks for mappings.
Adding a mirrored copy to a VDisk
Use the Add Copy to VDisk panel in the SAN Volume Controller Console to
add a mirrored copy to the selected virtual disk (VDisk). Each VDisk
can have a maximum of two copies.
Adding a copy to a VDisk using the CLI
You can use the
command-line interface (CLI) to add a mirrored
copy to a virtual disk (VDisk). Each VDisk can have a maximum of two
copies.
Splitting a VDisk copy
You can create a separate virtual disk (VDisk) by splitting a synchronized
VDisk copy. You can select a copy to split off from the VDisk and set its
attributes.
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).
Shrinking VDisks
You can use the SAN Volume Controller Console to
make a target or auxiliary virtual disk (VDisk) the same size as the
source or master VDisk when you create FlashCopy® mappings, Metro
Mirror relationships, or Global Mirror relationships.
Verifying and repairing mirrored VDisk copies
The virtual disk (VDisk) copy verification process checks
if data on mirrored VDisk copies match. You can choose repair options
if differences are found during the verification process.
Repairing offline space-efficient VDisks
When a space-efficient virtual disk (VDisk) is taken offline
because its metadata is corrupted, you can use the Repairing Space-Efficient
VDisk panel to repair the metadata. The repair operation automatically
detects corrupted metadata and performs any necessary repair actions.
