Configuring Automatic volume growth
The Automatic Volume Growth feature is a command to have an individual volume grow (increase capacity) automatically by a user specified amount when the used disk space on the volume reaches a certain threshold. This threshold is set in the Capacity Monitoring wizard.
By automating the growth process, the Automatic Volume Growth feature enhances the capability of dynamic volumes to expand without requiring that the underlying disks be offline.
The advantages of this automatic process include the following:
Reduced need for a System Administrator to monitor volume capacity at all times.
Disk space is allocated on an as-needed basis; no idle excess capacity.
Space is always available for mission-critical data.
Automatic Volume Growth is set at the individual volume level and is turned off by default. You need to enable it for each volume you want to grow. Enabling a volume for Automatic Volume Growth requires the volume to be enabled for Capacity Monitoring.
The following gives more information about configuring Automatic Volume Growth in a cluster environment.
See Enabling Automatic Volume Growth in a non-clustered and clustered environment.
Note:
Dynamic disks belonging to a Microsoft Disk Management Disk Group do not support Automatic Volume Growth.
A policy file is used to record the settings for the volumes that use the Automatic Volume Growth feature. This XML file is automatically set up when Automatic Volume Growth is enabled, and it reflects the current settings for a volume. You can view and change the current settings with the Automatic Volume Growth wizard.
Alternately, you can use SFW's Rule Manager event notification function to grow a volume automatically. With Rule Manager, you can set up a script that can grow a volume automatically when a specified threshold is reached.
The current Automatic Volume Growth settings of all your volumes are also available to help you manage your volumes. Selecting the volume node in the tree-view of the GUI and selecting Automatic Volume Growth Information in the context menu, displays the growth size, the maximum growth limit, and if Automatic Volume Growth is enabled for your volumes.
The following topics give more information on Rule Manager:
Automatic Volume Growth is also available in the CLI and with vxvol autogrow.
Warning:
If you use a script to enable volume growth, do not enable the Automatic Volume Growth function through the Automatic Volume Growth wizard. If you enable a volume growth script and enable the Automatic Volume Growth function for a volume, the volume increases in size by the combined amount. If you prefer to use the new feature, you must disable the script.
