Table: IBM Extent Pool Summary
Column name | Description |
|---|---|
|
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 |
