Disk Management 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. 80 NAS 4000s and 9000s Administration Guide

NAS 4000s and 9000s Administration Guide
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
