Setting a dynamic capacity policy Set a policy to automatically extend or shrink a host volume. Considerations • You can only use the GUI to set a dynamic capacity policy. • A dynamic capacity policy can be applied simultaneously to multiple host volumes. • An extend policy and a shrink policy can be implemented for the same host volume if desired. • When using an extend policy or shrink , the size of both the file system and the underlying virtual disk is changed when the specified threshold is reached. • When selecting a policy enforcement period, make sure you take into account the current setting for the automatic storage refresh interval. See Refreshing resources (automatic). If the current refresh interval is longer than the policy enforcement period, the policy may not be triggered properly. For example, assume that the refresh interval is set to 6 hours and the extend policy enforcement period is set to 4 hours. The policy enforcement period lies between refresh periods. If the policy threshold is exceeded during the refresh period, it will not be detected and the extend policy will not be triggered. • If the set threshold is reached but the host volume cannot be resized, an event will be logged and displayed in the event panel. This can occur in the following situations: • The threshold was reached during a period of time that falls outside of the specified policy enforcement period. Resize can only during the enforcement period. • The specified maximum resize limit for the host volume has been reached. Procedure 1. In the navigation pane, select Host Volumes. 2. On the Host Volumes tab, select the host volume for which you want to set a dynamic capacity policy. Select multiple host volumes to apply the policy to all of them. 3. Select Actions > Set Dynamic Capacity Policy. The Set Dynamic Capacity Policy wizard opens. Follow the instructions in the wizard. Editing a dynamic capacity policy Change an existing dynamic capacity policy. Considerations • You can only use the GUI to edit a dynamic capacity policy. Procedure 1. In the navigation pane, select Host Volumes. 2. On the Host Volumes tab, select the host volume for which you want to set a dynamic capacity policy. 3. Select Actions > Edit Dynamic Capacity Policy. The Set Dynamic Capacity Policy wizard opens. Follow the instructions in the wizard. Removing a dynamic capacity policy Remove an existing a dynamic capacity policy. 138 Host volumes
