Disk Partitions/Volume Group Details
Expand the Volume Group Details (click on the arrow) to identify unallocated space in a Volume Group and logical volumes that are not being used by hosts. These details highlight inefficient use of storage.
This table will be present only when there are one or more volume groups set up on the selected host. The table displays each volume group along with the physical disks that have been allocated to the volume group and the logical volume details. Use this table to find any un-allocated storage--that is, space that is available within the volume group that has not been assigned to a logical volume.
If the Array name is missing from a table entry it is because it is a local disk.
Oracle Containers include storage pools that are represented in the Volume Group column of this table. The corresponding Disk Capacity column displays the virtual disk capacity allocated to the Zone.
Note:
Totals in a Volume Group reflect usable capacity--so, for example, RAID 1 mirrored disks will show only the capacity that is usable.
Table: Disk Partitions/Volume Group Details
Column name | Description |
|---|---|
Volume Group | The name of the volume group. |
Type | LUN or DSK. |
Name | LUN or Disk name. |
Array | Storage array; if this field is empty, it means it is a local disk (DAS). |
Physical Disk Name | Name of the disk. |
Partition Name | The disk partitions that are part of the volume group. |
Size | Disk capacity, derived from Host Resources data collection. This is the same as the value returned from df -k. |
VVM Disk Capacity | Volume manager disk capacity. |
Table: Disk Partitions/Volume Group Details
Column name | Description |
|---|---|
RAID Type | Disk or virtual disk RAID type associated with the storage pool. |
Disk Name | Name of the disk or virtual disk. |
Array | Array where the disk and LUN reside. |
Disk Capacity | Capacity that has been allocated. In the case of Oracle containers, this is the capacity allocated to the zones. |
Table: Disk Partitions/Volume Group Details
Column name | Description |
|---|---|
Zone | Oracle VM (OS instance) |
Volume | If the volume value is blank, the Used value represents the data set used capacity. If there is a value listed for the volume, this means it is for a file system. |
Used | Represents the capacity "written to" the file system. |
Table: Disk Partitions/Volume Group Details
Column name | Description |
|---|---|
Logical Volume | Logical volume name. If listed as Un-allocated, it is not mounted. |
Size | Usable volume space. |
Physical Size | Physical size of logical member. |
Note:
The Capacity and Used columns are aggregated and then converted to the units selected in the Advanced option of the report from which the Host Utilization Detail was launched. Note that in the conversion to the displayed units, the totals may appear to be slightly inaccurate. This is due to the division or multiplication by 1024.
