Increasing the Capacity of a Standard Virtual Disk
Use this option to increase the storage capacity of an existing .
An increase in ??capacity may be achieved by using either free capacity available on of the standard virtual disk, or by adding unconfigured capacity (in the form of unused physical disks) to the disk group of the standard virtual disk. Use this option when no free capacity exists on the disk group.
Note: An increase in capacity might be achieved for standard virtual disks that have not yet been registered with the operating system. If a has not been defined, and a utility (or similar utility) has not been used to register the virtual disk with the operating system, an increase in capacity might be achieved.
A standard virtual disks storage capacitycannotbe increased if:
One or more are in use in the virtual disk.
The virtual disk has a Non-Optimal status.
Any virtual disk in the disk group is in any state of modification.
The that owns this virtual disk is in the process of adding capacity to another virtual disk (each RAID controller module can add capacity to only one virtual disk at a time).
No free capacity exists in the disk group, andno unconfigured capacity (in the form of physical disks) is available to be added to the disk group.
Example: You have created a new standard virtual disk with a capacity of 10 GB, and once created, you realize that its capacity needs to be increased another 5 GB. The operating system does not yet recognize the standard virtual disk because a virtual disk-to-LUN mapping has not been defined, and the hot_add utility (or similar utility) has not been run. At this point, the standard virtual disks capacity might still be increased.
Caution:Possible Loss of Capacity. Increasing the capacity of a standard virtual disk is only supported on certain operating systems. If you increase the virtual disk capacity on a that is unsupported, the expanded capacity will be unusable and you cannot restore the original virtual disk capacity. For information on supported operating systems, see Increase Virtual Disk Capacity: Additional Instructions.
Important:
A maximum of two physical disks might be added at one time to increase virtual disk capacity.
If the capacity of a or participating in a is increased, the for the Remote Virtual Disk Mirror will be the minimum of the primary virtual disk and secondary virtual disk actual capacities.
1
Highlight a standard virtual disk in the Logical View of the . Then, select Virtual Disk >> Increase Capacity.
Important: When no free capacity and unconfigured capacity exists, the Increase Capacity option is unavailable.
If free capacity is available, the maximum capacity available is displayed in the Increase capacity by spinner box. If there is no free capacity on the disk group, the free space that is shown in the Increase capacity by spinner box is 0. Physical Disks must be added to create free capacity on the disk group of the standard virtual disk.

Use one of the following methods to increase capacity:
To do this
Follow these steps
Increase virtual disk capacity using free capacity on the disk group of the standard virtual disk
1
Accept the final capacity or use the Increase capacity by spinner box to adjust the capacity.
The Final Capacity is updated to display the total capacity of the selected virtual disk plus any additional capacity specified.
2
Click OK.
3
Type Yes, and click OK.
The Logical View is updated. The virtual disk having its capacity increased shows a status of Operation in Progress , together with its original capacity and the total capacity being added.
In addition, the involved shows a reduction in capacity. If all of the free capacity is used to increase the virtual disks size, then the Free Capacity node involved will be removed from the Logical View.
Increase virtual disk capacity by adding unconfigured capacity (physical disks) to the disk group of the standard virtual disk
1
If no are available, and empty slots in the expansion enclosures are available, insert new physical disks. For more information, refer to your Expansion Enclosure User Guide .
If no unassigned physical disks are available, and there are no empty slots available in the expansion enclosures, install another expansion enclosure and additional physical disks. For more information, refer to your
RAID Enclosure and Expansion Enclosure Installation Guides
.
2
Click Add Physical Disks.
The Add Free Capacity (Physical Disks) dialog is displayed. Information for the current disk group is displayed and includes the level, free capacity available, expansion enclosure and slot details, enclosure loss protection status, and the capacity of the physical disks in the disk group.
Based on the RAID level and enclosure loss protection of the current disk group, a list of unassigned physical disks is displayed.
Note: If the RAID level of the disk group is or , and the expansion enclosure has enclosure loss protection, the Display only physical disks that will ensure enclosure loss protection check box is selected by default.
3
Select a single physical disk, or two physical disks to be added.
Important: Mixing different within a single disk group or virtual disk is not permitted.
4
Click Add.
Check the Physical Disks to add [enclosure, slot] area to ensure the correct physical disks have been added.
5
Accept the final capacity or use the Increase capacity by spinner box to adjust the capacity.
6
Click OK.
7
Type Yes to confirm the operation, and click OK to continue.
The Logical View is updated. The virtual disk having its capacity increased shows a status of Operation in Progress , together with its original capacity and the total capacity being added. In addition, the Free Capacity node involved in the increase will show a reduction in capacity.
If a Free Capacity node did not exist prior to the addition of capacity, a new Free Capacity node is created and displayed in the Logical View. Unassigned physical disks added (unconfigured capacity) change in the Physical View to assigned physical disks, and become associated with the virtual disks disk group.
Increase Capacity Progress
To view the progress of the increase in capacity, highlight the virtual disk and select Virtual Disk >> Properties.
