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.
raid5. Indicates that, in addition to the actual data, one set of parity bits exists for the logical volume. Single parity protects against the loss of one drive. Single parity is implemented as a variant of the RAID 5 storage technology.
raid6. Indicates that, in addition to the actual data, two sets of parity bits exist for the logical volume. Double parity protects against the loss of one or two drives with a slight cost of write performance. Double parity is implemented as a variant of the RAID 6 storage technology.
raid10. Indicates that no parity bits exist for the volume. Instead, the system writes the data in two different locations. Mirroring protects against the loss of at least one drive and possibly more drives with an improvement of the performance of random write operations. Mirrored RAID is implemented as a variant of the RAID 10 storage technology.
default. Indicates that the level of protection is determined by the storage class. For large form factor (capacity) hard disk drives, the RAID 6 level of protection is the default. For the other storage classes, the RAID 5 level of protection is the default.
1. 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. Single parity is implemented using RAID 5 technology.
2. 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. Double parity is implemented using RAID 6 technology.
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.
