IBM XIV Storage Pool Details
Detail reports are related to a specific enterprise object, such as a backup job. You can only access detail reports through a link presented in the context of a main report, providing additional information that augments the main report. Detail reports cannot be generated, customized, or saved, as they are specific to the report from which they were derived. They are not available in search results.

The XIV Storage Pool Details offers a graphical representation of pool usage. Note that thin-provisioned pools have a soft limit greater than the hard limit.

Column name | Description |
|---|---|
|
XIV Storage Pool Details | |
|
Storage Pool |
Storage Pool name |
|
Storage Array |
Storage Array name |
|
Thin Provisioned |
Yes = thin provisioned |
|
Hard Limit |
Maximum physical capacity that can be used volumes and snapshots in the pool. |
|
Used |
Physical capacity minus Free Hard size |
|
% Utilized |
Used/Hard Limit |
|
Available |
Amount of available pool space |
|
Allocated |
Allocated storage is physical storage consumed, including parity overhead and system overhead. A gap between raw and allocated capacity may indicate unused capacity, such as drives in a rack that are not in use. |
|
Soft Limit |
The logical amount of space for all storage pools in the array. A soft limit greater than the hard limit indicates thin provisioning. |
|
Snapshot Used |
Amount of storage used by snapshots |
|
Snapshot Reserved |
Amount of storage for snapshot reserves |
|
Lock Status |
If this field is empty, it means Not Locked |
|
Lock Behavior |
Lock behavior, such as Read Only |
|
Hard Status |
Physical Capacity Status: If % Util < 2% = empty, if % Util > 95% = near capacity, if % Util > 2% and <30% = over-provisioned |
|
Soft Status |
Logical Capacity Status: If % Util < 2% = empty, if % Util > 95% = near capacity, if % Util > 2% and <30% = over-provisioned |
|
Logical Storage Pool | |
|
Volumes |
Sum of the capacity of all master volumes. |
|
Snapshots |
Amount of storage pool space consumed by snapshots |
|
Available Snap |
Total snapshot size minus space used by snapshots |
|
Unused |
Amount of free soft (logical) storage in the pool |
|
Physical Storage Pool | |
|
Consumed |
Sum of all capacity used by master volumes |
|
Allocated Unused |
Amount of storage pool space used by volumes (see Used in first column of this report) minus Consumed (value shown above) |
|
Snap Consumed |
Amount of storage pool space used by snapshots |
|
Unused |
Free hard (physical) space |
|
List of Volumes/Snapshots | |
|
Name |
Volume/Snapshot name |
|
Allocated |
Allocated storage is physical storage consumed, including parity overhead and system overhead. A gap between raw and allocated capacity may indicate unused capacity, such as drives in a rack that are not in use. |
|
Used |
Used capacity in GB |
|
% Util |
% of volume or snapshots used |
|
Master |
Either Volume name for snapshots to volumes or Snapshot Name for snapshots of snaps |
|
Consistency Group |
Consistency group name, if exists, links to CG Detail Report |
|
Locking Status |
If this field is empty, it means it is Not Locked. |
|
Serial # |
Snapshot serial number |
|
Host |
Links to the Host Utilization Details |
|
Host LUN |
The LUN to which the host is mapped |
|
Mount Point |
The host's filesystem mount point for this LUN. It is possible to have zero mount points and filesystems, in the scenario where a LUN has been allocated to the host, but the host has not yet made use of it by creating a filesystem and mounting it. |
|
Filesystem |
The host's filesystem or drive name to which the LUN maps. LUNs simply appear as disks to hosts. |
|
Host Storage Domain |
A logical group of hosts that can be accessed via the same physical storage port, with each host accessing its own unique Snapshot. |
|
Array Port WWN |
The unique identifier, World Wide Name, of the array port address. |
