Returns the amount of storage that can be allocated to a LUN.

You can run the lun ‑maximumCapacity command to display the actual storage capacity that could be allocated to a LUN. The Oracle FS System returns the maximum capacity (in bytes) that is available for creating a LUN, a copy of a LUN, or increasing the size of a LUN. You can examine the impact of different QoS properties on the storage capacity by running the lun ‑maximumCapacity command with different values.
Enables data striping for the LUN across the entire Drive Enclosure.
premium. Indicates the highest priority for responding to requests in the processing queue. For Auto-Tier LUNs, busy LUN extents receive the highest priority when the system migrates the data to the higher-performing storage tiers.
high. Indicates the next highest priority for responding to requests in the processing queue. For Auto-Tier LUNs, busy LUN extents receive the next highest priority when the system migrates the data to the higher-performing storage tiers.
medium. Indicates an intermediate priority for responding to requests in the processing queue. For Auto-Tier LUNs, busy LUN extents receive an intermediate priority when the system migrates the data to the higher-performing storage tiers.
low. Indicates the next to lowest priority for responding to requests in the processing queue. For Auto-Tier LUNs, busy LUN extents receive the next to lowest priority when the system migrates the data to the higher-performing storage tiers.
archive. Indicates the lowest priority for responding to requests in the processing queue. For Auto-Tier LUNs, busy LUN extents receive the lowest priority when the system migrates the data to the higher-performing storage tiers.
Indicates that, in addition to the actual data, one set of parity bits exists for the logical volume. This parity level protects against the loss of one drive.
Indicates that, in addition to the actual data, two sets of parity bits exist for the logical volume. This parity level protects against the loss of one or two drives with a slight cost to write performance.
Indicates that no parity bits exist for the volume. Instead, the system writes the data in two different locations. This RAID level protects against the loss of at least one drive and possibly more drives with an improvement of the performance of random write operations.
Indicates that the level of RAID protection is determined by the Storage Class. For large form factor (capacity) hard disk drives, RAID 6 is the default level of protection. For the other Storage Classes, RAID 5 is the default level of protection.
Identifies the number of copies of the parity bits that the Oracle FS System creates for the volume
Stores the original user data plus one set of parity bits to help in the recovery of lost data. Access to the data is preserved even after the failure of one drive. 1 parity is implemented using RAID 5 technology and is the default redundancy level for the Storage Classes that specify the performance-type media.
Stores the original user data plus two sets of parity bits to help in the recovery of lost data. Access to the data is preserved even after the simultaneous failure of two drives. 2 parity is implemented using RAID 6 technology and is the default redundancy level for the Storage Classes that specify the capacity-type media.
Indicates the type of storage media to be used for the LUN. If you do not use the ‑profile option, the ‑storageClass option is required if the Oracle FS System supports two or more Storage Classes.
capDisk. Specifies that the data is stored on high-capacity, rotating hard disk drives (HDDs). This Storage Class optimizes capacity at some sacrifice of speed. For the FS1, this storage class provides the lowest cost for each GB of capacity.
perfDisk. Specifies that the data is stored on high-speed HDDs. This Storage Class sacrifices some capacity to reduce the access time and the latency of the read operations and of the write operations.
perfSsd. Specifies that the data is stored on SSDs that are optimized for the performance of balanced read and write operations.
capSsd. Specifies that the data is stored on solid state drives (SSDs) that are optimized for the performance of read operations and for capacity. The write performance for this Storage Class is sacrificed somewhat to achieve the optimizations for read performance and for capacity.
Specifies the FQN or GUID of the Storage Domain that contains the LUN. If you do not include this option, and there is only one Storage Domain on the Oracle FS System, the system uses the default Storage Domain in which to create the LUN. If you do not include this option, and there are multiple Storage Domains available, the system prompts you to specify a Storage Domain.
Specifies the number of drive groups across which to stripe the LUN. Values are 1 to 64. If you do not specify a size, the system uses the maximum possible stripe width.
The following global options can be used for fully formed fscli commands:
The command completes successfully.
The command returns with an error.
The session times out.
Inspects the validity of the command syntax, not the semantics. Used to test the structure of a command without running the command. Does not determine whether errors would be produced if you issue a structurally correct command with the input provided.
Directs the CLI to prompt you to supply a session key when you issue the command. The CLI displays Sessionkey: as the prompt. To obtain a session key, log in with the ‑returnKey option specified. After the session is established, the session key is displayed in STDOUT. If you request a session key, the ‑sessionkey option is required syntax for all commands that are issued in a given session. In environments with more than one Oracle FS System, the session key is used to determine to which Oracle FS System to direct the command for validation. Session keys are also used to establish two or more CLI sessions when using a shared administrator account.
