Dynamic Growth

Dynamic growth is a feature of the NAS server, which provides for growth of a volume or

partition to meet expanding storage requirements without the need to take volumes offline or

incur downtime. Growth may occur in three forms:

■ Extend unallocated space from original LUNS.

■ Alter LUNs to contain additional storage.

■ Add new LUNS to the system. The additional space is then extended into through a variety

of means depending on which type of disk structure is in use.

Expanding a LUN

Expanding an existing LUN is accomplished using the storage array configuration software

applicable to the storage array in use. In the case of the MSA1000 controller, this is

accomplished via the Array Configuration Utility presented on the Disk page. LUN expansion

may occur in Disk Arrays where space is available. If insufficient space is available, additional

physical disks may be added to the array dynamically.

Figure 41: Expanding a LUN (MSA1000 only)

To extend a LUN where space is available in the array (MSA1000 only):

1. Click the Disks tab.

2. Click Array Management.

3. Click Array Configuration Utility and log in.

4. Select the appropriate array controller and the appropriate array that the logical drive is

contained in.

5. Select the appropriate logical drive.

6. Select Extend Size.

7. Enter the total size of the logical drive in MB (not just the amount to be added) and click

OK.
