GXCC Function bar
“Delete Snapshot(s)” button:
Clicking on this button causes all snapshots which are marked with “yes” to be deleted. The
system acknowledges the user input with an information window containing the information
”snapshot(s) will be deleted”. If you press “Delete Snapshot(s)” without marking one or
more ISPs beforehand, the message “no snapshots selected for deletion or deletion failed”
is issued.
Modify threshold values
The snapshots may require a large amount of memory, and as they can also be generated
automatically mechanisms have been implemented which are designed to prevent a
memory overflow being caused by the writing of snapshots. These mechanisms use
threshold values which you can adapt to your requiremetns using the “Modify threshold
values” function. Each of the defined values appies for the entire CentricStor system.
When the function is called, the “Limits for creation / deletion of snapshots” window is
opened:
Meaning of the individual fields:
Retention period (days)
Snapshots which are older than the number of days specified are deleted automatically.
Free space threshold (percentage)
This field shows the percentage of free memory which must not be fallen below when
snapshots are saved.
– If storing a snapshot would cause the percentage to drop below the value entered,
no snapshot is saved. However, a snapshot directory is created which is assigned
the status “empty” (see the preceding section “Show survey / Delete Snapshot(s)”).
