For thin volumes capable of allocating space on demand,
you can change the limit that restricts the allocated capacity to
which a thin volume can automatically expand. You also can change
the percentage point at which an alert (warning threshold exceeded)
is sent to the Notifications area on the Home page when a thin volume
is near the allocated capacity limit. You can choose to enable or
disable this alert notification.
About
this task
The system automatically
expands the allocated capacity based on the allocated capacity limit.
The allocated capacity limit allows you to limit the thin volume’s
automatic growth below the reported capacity. When the amount of data
written gets close to the allocated capacity, you can change the allocated
capacity limit.
When changing a thin volume's allocated capacity limit
and warning threshold, you must take into account the space to be
consumed by both the volume’s user data and copy services data.
- Select .
- Select the
Thin Volume Monitoring tab.
The Thin Volume Monitoring view
appears.
- Select the thin volume that
you want to change, and then select .
The Change Limit dialog
box appears. The allocated capacity limit and warning threshold setting
for the thin volume you selected appear in this dialog box.
- Change the
allocated capacity limit and warning threshold as needed.
Table 1. Field Details
| Setting |
Description |
| Change allocated capacity limit to...
|
The threshold at which writes fail, preventing
the thin volume from consuming additional resources. This threshold
is a percentage of the volume's reported capacity size.
|
| Alert me when...
(warning threshold)
|
Select the check box if you want the system
to generate an alert when a thin volume is near the allocated capacity
limit. The alert is sent to the Notifications area on the Home page.
This threshold is a percentage of the volume's reported capacity size.
Clear the check box to disable the warning threshold alert notification.
