IBM Extent Pool Summary
Use Search to find a template, report or dashboard by name. Search is case insensitive, supports partial entries, and will display a list of potential matches.
As you enter the name in the Search field, up to 10 potential matches are displayed. If the template, report or dashboard is shown, you can select and run it directly from the match list. You can also click All Items in the match list to go directly to the Search Results.
StorageConsole provides different navigation options to slice and examine your collected data. You can explore the data by using the APTARE customizable report templates or by using parts of your IT infrastructure as entry points. The Inventory Navigator serves as a browser for your infrastructure by object type. See also Exploring Your Inventory.
Use the Reports tab to examine the StorageConsole catalog of templates, dashboards and reports - organized by products along with user-created, and system folders. This report is located here:
Understanding IBM Enterprise Storage Capacity Calculations
Capacity values for IBM arrays may appear different from what is reported by the IBM CLI or IBM Tools, as IBM uses a decimal gigabyte—10^9 bytes, while StorageConsole uses 1024 for a KB when converting to GB.
For FB open systems hosts, an extent is 1 GB. For CKD IBM zSeries or S/390 systems, an extent is 1 cylinder (.92 GB).
In the Scope Selector, you can narrow the report output by selecting values for the following criteria:
Storage Types: fb, ckd
Rank Status: below, exceeded, full
Name
Extent Pool name
Storage System
The physical storage system (storage array) on which the extent pool resides
Rank Group
A rank can only be assigned to one extent pool, but more than one rank can reside in an extent pool.
Storage Type
Fixed block (FB) or Count-Key-Data (CKD).For FB, an extent is 1 GB. For CKD, an extent is 1 cylinder (.92 GB).
Status
Rank Status:
below - % of available extents is less than threshold
exceeded - % of available extents is greater than threshold
full - 0 extents are available
Total Capacity
Sum of the capacity of all extents in this pool
Available Capacity
The amount of space in this extent pool that is currently available; this value is derived from the total capacity minus the allocated capacity
Available Extents
The number of extents that are available to the logical volume
Reserved Extents
The number of extents that are in reserved (this space must be explicitly released before the logical volume can use it)
# of Volumes
The number of logical volumes that have been configured from this extent pool; this is the storage that can be given to a host
# of Ranks
The number of ranks in this extent pool—1 or 2
