Displays properties of the available Storage Domains and associated drive groups.
Name

Specifies the name of the Storage Domain and lists the Drive Enclosures and drive groups that are assigned to the domain.

Status

Displays the status of the Storage Domains and of the drive groups that are associated with those Storage Domains. Normal means that no action is required.

Normal

Indicates that the drive group is accessible and no action is required.

Degraded Warning

Indicates that the drive has failed in the drive group, but the drive group is still accessible. Replace the failed drive. If the drive group is the primary drive group, then replace the drive immediately. The primary drive group contains system overhead, including all system configuration data.

Degraded Critical

Indicates that two or more of the drives have failed. The drive group can become inaccessible unless you replace the drives.

Failed

Indicates that multiple drives have failed. The drive group is not accessible. Replace the failed drives. After the failed drives are replaced, the drive group becomes accessible.

Unknown

Indicates that the drive status information is not available to display.

Tier Reallocation

Identifies the tier reallocation status of the Storage Domain. When tier reallocation is enabled, the Oracle FS System dedicates resources and uses statistical data and QoS priority property to migrate data from one storage tier to another.

Valid states:
Enabled

Indicates that the tier reallocation is active on the Storage Domain. Enabled makes possible the migration of high-usage data to higher performing storage tiers in this Storage Domain.

Disabled

Indicates that tier reallocation is not active on the Storage Domain. Disabled does not allow the migration of high-usage data to higher performing storage tiers in this Storage Domain.

Statistics Collection Disabled

Indicates that statistical data used by the Oracle FS System to migrate the data is not collected. Oracle recommends not using this option as the statistical data is required for the tier reallocation process.

Tier reallocation disabled

Indicates that the tier reallocation is not active. The statistics collection is active.

Media Type

Specifies the category of physical media that comprises the drive group.

Valid media types:
Performance SSD

Specifies that the data is stored on solid state drives (SSDs) that are optimized for the performance of balanced read and write operations.

Capacity SSD

Specifies that the data is stored on SSDs that are optimized for the performance of capacity and for read operations. The write performance for this Storage Class is sacrificed somewhat to achieve the optimizations for read performance and for capacity.

Performance Disk

Specifies that the data is stored on high-speed hard disk drives (HDDs). This Storage Class sacrifices some capacity to reduce the access time and the latency of the read operations and of the write operations.

Capacity Disk

Specifies that the data is stored on high-capacity, rotating HDDs. This Storage Class optimizes capacity at some sacrifice of speed. For a storage system that does not include tape storage as an option, this Storage Class always provides the lowest cost for each GB of capacity.

Enclosure Chassis ID

Displays the numeric identifier of the Drive Enclosure. The Enclosure Chassis ID is located and displayed on the front of the Drive Enclosure. The numeric values range from 01 to 99; the hexadecimal values from A0 to FF.

Physical Capacity

Allocated

Displays the amount of capacity that has been assigned and designated to all logical volumes residing on the indicated Storage Domain.

Free

Displays the amount of capacity that is available for allocation in the indicated Storage Domain.

Unavailable

Displays the amount of capacity that is being initialized. This value typically results from a volume having been deleted. This value decreases over time while the value for free space correspondingly increases for the indicated Storage Domain.

Total Capacity

Displays the total amount of raw capacity provided by the Drive Enclosures that are defined within the indicated Storage Domain.

Physical Distribution
Provides a graphical representation of the capacity that is used compared to the maximum that is allocated.
