Setting a percent full warning threshold

Page 26 highlights

Setting a percent full warning threshold To receive a warning alert when storage capacity reaches a specified limit, set the percent full warning threshold. You can set a warning threshold for any application component, user-defined application, and shared folder that ASM manages. An iSCSI LUN application will not have a warning threshold. By default, the warning threshold is set to 80%. To change it, enter a new percent value on the Advanced window. After you set a warning threshold, ASM changes the status indicator for the application component, user-defined application, or shared folder when this threshold has been surpassed. This is a warning only; no hard limits are enforced on storage capacity as a result of setting this value. The warning is visible in these places: • A yellow warning icon appears on the application component, user-defined application, or shared folder icon in the content pane. • As an alert in the Properties window. NOTE: For shared folders and local storage applications, you can set an enforceable limit (or quota) for allocated storage, as well as a warning threshold. For more information, see Enforcing an allocated storage limit for shared folders and local storage applications. Enforcing an allocated storage limit for shared folders and local storage applications ASM provides a way to enforce an allocated storage limit for shared folders and local storage applications. If enforced, the system does not allow the amount of allocated space for a shared folder and local storage application to be exceeded. If the capacity of the shared folder and/or local storage application surpasses the percent full warning threshold and reaches the allocated space limit, the status changes from Warning to Critical in the content pane, and users are blocked from adding data to the shared folder and local storage application. NOTE: If you do not choose to enforce an allocated storage limit for a shared folder, the ASM status indicator still goes from Warning to Critical in the content pane; however, users are not blocked from adding data to the shared folder as long as there is still unallocated storage space on the logical disk where the shared folder resides. Data can be written to the shared folder until the logical disk is full. By default, the Enforce Allocated Limit (Quota) is set to No for all shared folders and local storage applications. To change this setting, do one of the following: • Using the Create a Shared Folder Wizard, change the Enforce Allocated Limit (Quota) setting on the Advanced window to Yes. • Select the shared folder in the content pane, click Properties in the Actions pane, click the Warning Threshold tab, and then select the Enforce Allocated Limit (Quota). 26 Hosting storage for applications and shared folders

Setting a percent full warning threshold
To receive a warning alert when storage capacity reaches a specified limit, set the
percent full warning
threshold
. You can set a warning threshold for any application component, user-defined application,
and shared folder that ASM manages. An iSCSI LUN application will not have a warning threshold.
By default, the warning threshold is set to 80%. To change it, enter a new percent value on the
Advanced window.
After you set a warning threshold, ASM changes the status indicator for the application component,
user-defined application, or shared folder when this threshold has been surpassed. This is a warning
only; no hard limits are enforced on storage capacity as a result of setting this value. The warning is
visible in these places:
A yellow warning icon appears on the application component, user-defined application, or shared
folder icon in the content pane.
As an
alert
in the Properties window.
NOTE:
For shared folders and local storage applications, you can set an enforceable limit (or quota) for allocated
storage, as well as a warning threshold. For more information, see
Enforcing an allocated storage limit
for shared folders and local storage applications
.
Enforcing an allocated storage limit for shared folders and local storage applications
ASM provides a way to enforce an allocated storage limit for shared folders and local storage
applications. If enforced, the system does not allow the amount of allocated space for a shared folder
and local storage application to be exceeded.
If the capacity of the shared folder and/or local storage application surpasses the percent full warning
threshold and reaches the allocated space limit, the status changes from
Warning
to
Critical
in the
content pane, and users are blocked from adding data to the shared folder and local storage
application.
NOTE:
If you do not choose to enforce an allocated storage limit for a shared folder, the ASM status indicator still
goes from
Warning
to
Critical
in the content pane; however, users are not blocked from adding data to
the shared folder as long as there is still unallocated storage space on the logical disk where the shared
folder resides. Data can be written to the shared folder until the logical disk is full.
By default, the Enforce Allocated Limit (Quota) is set to
No
for all shared folders and local storage
applications. To change this setting, do one of the following:
Using the Create a Shared Folder Wizard, change the Enforce Allocated Limit (Quota) setting on
the Advanced window to Yes.
Select the shared folder in the content pane, click
Properties
in the Actions pane, click the
Warning
Threshold
tab, and then select the
Enforce Allocated Limit (Quota)
.
