Expanding virtual disk capacity

The capacity of a virtual disk can be expanded online by using the Online Capacity Expansion/Reconfigure (OCE/Reconfigure). OCE/Reconfigure is a process that allows you to add storage capacity to an existing virtual disk. In most cases additional storage capacity can be added without taking the system offline.

NOTE: If an additional physical disk is required and the system does not support hot-swapping, the system must be turned off.

OCE/Reconfigure enables you to increase the total storage capacity of a virtual disk by integrating unused storage with the virtual disk.

Data can be accessed while the physical disks are added (if a system has hot-swap capability) and while data on the virtual disk is being redistributed.

For volume, RAID 1, and RAID 10, OCE/Reconfigure expands the virtual disk by using the available space of the physical disks, which have been members of the virtual disk. For RAID 0 and RAID 5, additional capacity can be attained by adding physical disks to the virtual disk.

NOTE:There will be performance degradation until the capacity expansion is completed.

NOTE:While the process of expanding the capacity of a virtual disk is in progress, removing and reinserting the drive that is part of this virtual disk is not supported. Users can reinsert the drive after the capacity expansion process is completed.
