Virtual Disk Copy Restrictions
Before you perform any virtual disk copy tasks, understand and adhere to the
restrictions listed in this section. The restrictions apply to the source virtual
disk, the target virtual disk, and the storage array.
• While a virtual disk copy has a status of In Progress, Pending, or Failed, the
source virtual disk is available for read I/O activity only. After the virtual
disk copy is complete, read and write I/O activity to the source virtual disk
are permitted.
• A virtual disk can be selected as a target virtual disk for only one virtual
disk copy at a time.
• A virtual disk copy for any virtual disk cannot be mounted on the same
host as the source virtual disk.
• Windows does not allow a drive letter to be assigned to a virtual disk copy.
• A virtual disk with a Failed status cannot be used as a source virtual disk or
target virtual disk.
• A virtual disk with a Degraded status cannot be used as a target virtual
disk.
• A virtual disk participating in a modification operation cannot be selected
as a source virtual disk or target virtual disk. Modification operations
include the following:
– Capacity expansion
– RAID-level migration
– Segment sizing
– Virtual disk expansion
– Defragmenting a virtual disk
NOTE: The following host preparation sections also apply when using the virtual
disk copy feature through the CLI interface.
