Hybrid Drive
Is this physical storage medium removable? Removable storage implies that the removal action is part of normal operations and is expected to leave the data on the removable storage intact.
The formatted capacity of the physical storage medium in {{units}}.
The general activity status of this physical storage medium.
Time since boot in {{units}}. This MAY reflect S.M.A.R.T. PowerOnHours.
Is this physical medium capable of reporting S.M.A.R.T. statistics?
The general health of this physical storage medium. {{enum}}
Note: Health MAY be obtained from S.M.A.R.T. data where available.
Is this physical medium capable of being removed while the device is powered up? Hot-Swappable storage does not imply Removable storage; hot-swappable is an operation taken only when the disk has failed and needs to be replaced. The data on the hot-swapped storage will not remain intact.
This object provides SMART data information about the physical medium. SMART attributes are not standardized, but many vendors provide the data below.
Count of reallocated sectors. When the hard drive finds a read/write/verification error, it marks this sector as "reallocated" and transfers data to a special reserved area (spare area).
This process is also known as remapping, and "reallocated" sectors are called remaps. However, as the number of reallocated sectors increases, the read/write speed tends to decrease.
The raw value represents a count of the number of bad sectors that have been found and remapped. Thus, the higher the attribute value, the more sectors the drive has had to reallocate.
Count of hours in power-on state. It shows total count of {{units}} in power-on state.
Count of retry of spin start attempts. This attribute stores a total count of the spin start attempts to reach the fully operational speed (under the condition that the first attempt was unsuccessful). An increase of this attribute value is a sign of problems in the hard disk mechanical subsystem.
The count of full hard disk power on/off cycles.
Current internal temperature in {{units}}.
Count of remap operations. The raw value of this attribute shows the total count of attempts to transfer data from reallocated sectors to a spare area.
Both successful and unsuccessful attempts are counted.
Count of "unstable" sectors (waiting to be remapped, because of unrecoverable read errors). If an unstable sector is subsequently read successfully, the sector is remapped and this value is decreased.
The total number of uncorrectable errors when reading/writing a sector.
A rise in the value of this attribute indicates defects of the disk surface and/or problems in the mechanical subsystem.
Total number of unrecoverable read errors.
Total number of off-track errors.
Total number of errors when writing a sector.
Percentage of the spare sectors that can be used for reallocations remaining.
Estimated number of {{units}} until the failure model in the device predicts the drive will fail. -1 means the failure model is unable to make a prediction.
This object provides information about each storage array (RAID) configured on this device.
Creating an instance of this object generates a disabled {{object}} instance. Before this new {{object}} instance can be enabled (via a SetParameterValues command), it MUST have the following parameters configured: {{param|Name}}, {{param|RaidType}}, and {{param|PhysicalMediumReference}}. Once an instance is enabled the following parameters become immutable for the life of the instance: {{param|Name}}, {{param|RaidType}}, and {{param|PhysicalMediumReference}}.
{{datatype|expand}}
A user-friendly name for this Storage Array.
Once this instance becomes enabled, this parameter will be immutable for the life of the instance.
The current status of this StorageArray.
Indicates a drive participating in an array is replaced, while the data striping and/or redundancy of the array are reestablished on the new disk. In this state, data operations to the array will function properly, but its performance could be significantly diminished.
The state when the RAID array is being first constructed, and the data striping and/or redundancy of the array are first being established. In this state, data operations to the array will function properly, but its performance could be significantly diminished and the redundancy might not be fully established.
Indicates the RAID array is not available. This might occur because the administrator explicitly has disabled the array, or because underlying elements of the array, such as the physical disks, are not ready.
Indicates the RAID array is fully operational.
Indicates an error condition exists within the RAID array. In this state, data operations to the array are not possible, and data loss might have occurred.
Indicates the loss of a drive only in a Raid Type of more than 2 drives, that can support multiple failures. Data redundancy continues to be available but with degraded capability.
Indicates the loss of data redundancy, and a possible degraded state. The array continues to perform read/write operations.
Enables or disables this StorageArray instance.
Note that after creation of the Storage Array, any subsequent writes to this parameter MUST be ignored as array type migration is not supported. To identify which RAID Types are supported, see {{param|.Capabilities.SupportedRaidTypes}}.
Once this instance becomes enabled, this parameter will be immutable for the life of the instance.
The total Usable Capacity of the Storage Array in {{units}}. This is computed by the system based on {{param|PhysicalMediumReference}} and {{param|RaidType}}. Disk size is a consideration, as many RAID Types use the smallest drive in the group for calculations.
Represents the physical medium used by this RAID. Each Physical Medium referenced by this parameter MUST exist within the same StorageService instance. A {{object|.PhysicalMedium.{i}.}} MUST only be referenced by one {{object|.StorageArray.{i}.}} instance.
Once this instance becomes enabled, this parameter will be immutable for the life of the instance.
This object provides information about each logical volume configured on this device. A logical volume can reside either on an instance of a single {{object|.PhysicalMedium.{i}.}} or on an instance of a single {{object|.StorageArray.{i}.}} instance, but it can not span multiple instances of either. {{param|PhysicalReference}} is used to define where this {{object}} instance resides.
Creating an instance of this object generates a disabled {{object}} instance. Before this new {{object}} instance can be enabled (via a SetParameterValues command), it MUST have the following parameters configured: {{param|Name}}, {{param|PhysicalReference}}, and {{param|Capacity}}. Once an instance is enabled the following parameters become immutable for the life of the instance: {{param|Name}}, {{param|PhysicalReference}}, and {{param|Capacity}}.
{{datatype|expand}}
The name of the partition for this logical volume.
Once this instance becomes enabled, this parameter will be immutable for the life of the instance. This parameter acts as the unique identifier for the instance, thus the device MUST NOT allow multiple {{object}} instances to use the same {{param}}.
The current status of this Logical Volume. {{enum}}
The default {{enum|Offline}} status will exist until this {{object}} is enabled.
Enables or disables this {{object}} instance.
Represents the physical medium or RAID where this {{object}} resides. The {{object|.PhysicalMedium.{i}.}} or {{object|.StorageArray.{i}.}} referenced by this parameter MUST exist within the same StorageService instance.
An AddObject followed by an enabling SetParameterValues on {{param|Name}}, {{param}}, and {{param|Capacity}} will cause the formatting of this logical partition and these parameters to become immutable for the life of this instance.
The file system for this {{object}} as it is currently formatted.
The Capacity of the Logical Volume in {{units}}.
Once this instance becomes enabled, this parameter will be immutable for the life of the instance.
The Amount of Used Space on the Logical Volume in {{units}}.
This value is specified in {{units}} and controls when {{param|ThresholdReached}} will have its value altered. If the value of {{param|UsedSpace}} plus the value of {{param}}r is greater than or equal to the value of {{param|Capacity}} then the value of {{param|ThresholdReached}} will be {{true}}, otherwise it will be {{false}}. Setting the value of this parameter to 0 will disable the Thresholding mechanism.
When {{param|ThresholdLimit}} > 0 and {{param|UsedSpace}} + {{param|ThresholdLimit}} >= {{param|Capacity}} this will be {{true}}, else {{false}}.
Is the Volume Encrypted? The type of encryption will be handled by the device internally and is not a matter for remote management.
The number of instances of {{object|.LogicalVolume.{i}.Folder.{i}.}} on this {{object}}.
This object provides information about each top-level folder configured on this logical volume. Each top-level folder allows the configuration of quotas and access permissions.
Creating an instance of this object generates a disabled {{object}} instance. Before this new {{object}} instance can be enabled (via a SetParameterValues command), it MUST have the {{param|Name}} configured. Folder instances are unique per {{object|.LogicalVolume.{i}.}} and the unique key for this object is {{param|Name}} which also means that once an instance is enabled {{param|Name}} becomes immutable for the life of the instance.
{{datatype|expand}}
Setting of this variable will add a new folder. The full hierarchical pathname of the folder MUST be specified.
All folders created on the Logical Volume will appear here, created locally or via AddObject.
The local directory name will be formatted as a UNIX-style directory name, for example: /home/ftp
The presence of a trailing `/' character is inconsequential, meaning that /home/ftp/ is the same as /home/ftp.
Once this instance becomes enabled, this parameter will be immutable for the life of the instance. This parameter acts as the unique identifier for the instance, thus the device MUST NOT allow multiple {{object}} instances within a {{object|.LogicalVolume.{i}.}} to use the same {{param}}.
Entry is enabled or disabled
What are the User authentication requirements of this folder? The following bitmap is used.
:11 = Authenticated Access required for Network protocols (NFS/AFP/SMB) and for non Network protocols (FTP/SFTP/HTTP/HTTPS)

Represents a user that has access to this folder. The instance of {{object|.UserAccount.{i}.}} referenced by this parameter MUST exist within the same StorageService instance.
What permissions the user account has over this {{object|.LogicalVolume.{i}.Folder.{i}.}}. This is an integer value like the xNIX systems use for access permissions, meaning that it is a 3-bit field with the following structure:
:100 = read field
:010 = write field
:001 = execute field
This object provides information about each user group configured for access permissions on this folder.
{{datatype|expand}}
Enables or disables the entry.
Represents a user group that is a collection of User Accounts that have access to this folder. The {{object|.UserGroup.{i}.}} referenced by this parameter MUST exist within the same StorageService instance.
What permissions the group members have over this {{object|.LogicalVolume.{i}.Folder.{i}.}} instance. This is an integer value like the xNIX systems use for access permissions, meaning that it is a 3-bit field with the following structure:
:100 = read field
:010 = write field
:001 = execute field
This object allows the configuration of per-folder storage quota management.
Enables or disables quota management for this folder.
Maximum size in {{units}} of the quota for this folder.
Current size in {{units}} of this folder.
This value is specified in {{units}} and controls when {{param|ThresholdReached}} will have its value altered. If the value of {{param|UsedSpace}} plus the value of this parameter is greater than or equal to the value of {{param|Capacity}} then the value of {{param|ThresholdReached}} will be {{true}}, otherwise it will be {{false}}. Setting the value of this parameter to 0 will disable the Thresholding mechanism.
When {{param|ThresholdLimit}} > 0 and {{param|UsedSpace}} + {{param|ThresholdLimit}} >= {{param|Capacity}} this will be {{true}}, else {{false}}.
