Calculating Parallel Access Volumes used capacity
After each Parallel Access Volumes operation, the Parallel Access Volumes Used Capacity value
is recalculated:
1.
Assign aliases to a new base volume and click Apply.
2.
Cancel all aliases in the corresponding CU and click Apply.
NOTE:
A base volume with no assigned aliases does not contribute the total used capacity
value.
3.
Uninstall base volumes using the VLVI/LUN (VLL) or External Storage software.
4.
Assign aliases to a new base volume by Dynamic Parallel Access Volumes or Hyper Parallel
Access Volumes function.
5.
Verify that used capacity is the sum of the capacities of base volumes which meet at least one
of the following conditions:
•
Base volumes to which alias volumes are or were assigned using Remote Web Console.
•
Base volumes which are accessed by alias volumes using Dynamic Parallel Access Volumes
or Hyper Parallel Access Volumes.
The calculation of the used capacity can be time-consuming as it takes three minutes for each CU
to calculate this value. If all 255 CUs have volumes, it can take up to 13 hours to calculate and
display the updated used capacity. During calculation, the latest value for the used capacity is
unavailable. All volumes defined to storage system are calculated. After the calculation has finished,
the brackets disappear and the latest value of the used capacity is displayed.
