A.16 Set Thin Provisioning Volume Parameters
A.16.1 Set Thin Provisioning Volume Parameters (Notification Setting)
Screen
Set the thresholds of the Thin Provisioning Pool for each volume.
When Resource Domains are registered in the ETERNUS DX400/DX8000 series, the displayed
Thin Provisioning Volumes differ depending on the current user account.
When logged on using a Total Administrator account, all the Thin Provisioning Volumes assigned
to Resource Domains are displayed. When logged on using a Resource Domain Administrator
account, only the Thin Provisioning Volumes that are assigned to the relevant Resource Domain,
and only the Thin Provisioning Volumes that are
assigned to the Shared Resource, are dis-
played.
When Resource Domains are not registered, all the Thin Provisioning Volumes registered in the
ETERNUS DX400/DX8000 series are displayed.
Refer to "A.4.2 Thin Provisioning Pool List (Volume List in the Pool) Screen" (page 678) for
details about the Volume List.
● Setting item
• Notice (%)
- Caution
Input the thresholds (*1) of Thin Provisioning Pool capacity for each volume in percent
figures(%) in the text box.
Specify the threshold between 1 and 200 (%). The default setting is "10 (%)".
*1: Threshold is used for monitoring the Thin Provisioning Pool capacity for each Thin Provisioning
Volume. Setting the threshold to a larger size facilitates faster notification by alarm.
(Example 1)
Free area of Thin Provisioning Volume = 10TB, Threshold = 10 (%)
Free area of Thin Provisioning Pool < 1.0TB (= 10TB × 10 (%))
→ Notifies "Caution" status (alarm notification).
(Example 2)
Free area of Thin Provisioning Volume = 10TB, Threshold = 50 (%)
Free area of Thin Provisioning Pool < 5.0TB (= 10TB × 50 (%))
→ Notifies "Caution" status (alarm notification).
*2: Migration source volume that fails to be deleted after RAID Migration has been comp leted, or
work volume that fails to be deleted after TPV balancing.
Thresholds cannot be input for Temporary Volumes (*2).
