DESCRIPTION

You can set various properties of the Storage Domain to accommodate the special needs of a collection of LUNs and of the applications that use those LUNs. The properties that can be specialized for a Storage Domain include the following:

The priority under which a background process runs
The frequency of the scans that the system performs to determine whether data progression for any auto-tiered LUNs needs to occur
For each Storage Class, the percentage of the drive capacity that can be used for the auto-tiered LUNs

Note: Administrators with primary administrator or admin1 roles are authorized to run the storage_domain ‑modify command.

OPTIONS

‑autoTierMaximumCapacities

Identifies, for each Storage Class in the Storage Domain, the maximum percentage of capacity that can be used for the QoS Plus storage tiers. The argument for ‑autoTierMaximumCapacities consists of one or more pairings of a Storage Class and the maximum percentage of its capacity that can be used for auto-tiered LUNs. For each pairing, the Storage Class and the corresponding percentage must be separated by a colon ( : ). Valid media types (sorted from the highest performance priority to the lowest performance priority):

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

‑disableAutomaticQosRebalancing

Specifies that the system does not automatically balance the existing volumes across the drive groups when you add drive groups to the Storage Domain. If you do not specify this option, the system retains the data distribution across the existing drive groups in the Storage Domain. By default, the feature is enabled.

‑disableTierReallocation

Turns off dynamic data progression for the LUN. The Oracle FS System does not migrate the LUN data to other Storage Classes.

The ‑disableTierReallocation option, when it is used on a Storage Domain, overrides the tier reallocation setting of individual LUNs.

‑disableTierReallocationStatistics

Specifies that the usage patterns of all of the LUNs in the Storage Domain are not collected. Disabling the collection of statistics prevents any data progression to occur that is based on LUN usage patterns. Re-enabling statistics collection resumes the collection of usage pattern statistics to determine when data progression is needed.

‑enableAutomaticQosRebalancing

Specifies that the system automatically balances the existing volumes across the drive groups when you add drive groups to the Storage Domain. The system distributes the data of the existing volumes to all of the drive groups in the Storage Domain.

‑enableTierReallocation

Turns on dynamic data migration for the LUN. The Oracle FS System migrates the LUN data to the appropriate Storage Class based on the usage patterns of the data.

The ‑enableTierReallocation option, when it is used on a Storage Domain, does not override the tier reallocation settings of individual LUNs that reside in the Storage Domain.

‑enableTierReallocationStatistics

Specifies that the usage patterns for all of the LUNs in the Storage Domain are analyzed and used to determine the optimum Storage Classes for placing the LUN data.

‑name

Specifies a new name for the Storage Domain. The name that you provide is used to create a new fully qualified name (FQN) for the Storage Domain. To ensure that the Oracle FS CLI software that is running on thePilot includes the spaces or dashes in the name, use double quotation marks around names containing spaces or dashes; otherwise, the software will generate a parsing error.

‑nHourScanCycles

Indicates the number of performance scan cycles that the Oracle FS System runs before the system runs a cost optimizing scan. A cost optimizing scan attempts to move the data that is less frequently accessed to the lower cost storage. For ‑nHourScanCycles, enter an integer that has a value in the range of 2 to 31.

‑performanceScanCycles

Specifies the delay in hours between the times that the Oracle FS System scans the auto-tiered storage structure to determine whether auto‑tiered LUNs need to have data moved to a higher performance Storage Class. Valid values: 1 to 168. Default value: 24.

This value is set for the specified Storage Domain only; the value does not change the scan delay for any other Storage Domains.

‑priority

Specifies the priority of the background processes when compacting or integrity checking the tiered storage:

default: Balances the impact and the speed based on the data access activity.
maximumSpeed: Increases the priority of the background operations.
minimumImpact: Allows the background processes to run when the processes do not significantly impact I/⁠O.

‑storageDomain

Specifies the fully qualified name (FQN) or the unique identifier (ID) of the Storage Domain to modify.

GLOBAL OPTIONS FOR SUBCOMMANDS

The following global options can be used for fscli command-subcommand pairs that do not include other command-line options:

‑help: Returns the context-sensitive help for the specified subcommand.
‑usage: Returns the subcommand syntax for the given command, including all of the options that are available for the command-subcommand pair.

GLOBAL OPTIONS FOR COMMANDS

The following global options can be used for fully formed fscli commands:

‑example

Returns sample output from the specified command.

Note: To see the output in XML format, include the ‑o xml option.

‑timeout timeout-in-seconds

Specifies the length of time (timeout-in-seconds) that the command line interface waits before another command is allowed to run. If the command takes longer to run than the specified time limit, the system continues processing the command, but the command prompt is made available so that you can issue another command. If the -timeout option is omitted, the command line interface blocks until the one of the following conditions is met:

The command completes successfully.
The command returns with an error.
The session times out.

Note: Be sure to check the state of the system after initiating a long running command with the ‑timeout option. Many fscli commands run a series of underlying commands in sequence. When the timeout value is reached before all of the underlying commands have completed, the fscli command does not complete with the outstanding tasks reporting a failure status.

‑outputformat | ‑o { text | xml }: Controls the type of the output the system returns from a command. If the ‑outputformat option is not included, the format of the output defaults to simple text. If xml is provided, the output is a collection of XML elements.
Note: For XML output, if internal errors occur during command execution, each error is included in a separate <ErrorList> tag.

‑verify: 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.
‑sessionkey: 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.
‑u admin-user ‑oracleFS oracle‑fs-system: Routes the command to a particular Oracle FS System for execution. This option passes the name of the administrator account to use when opening the session on the specified system. Identify a specific Oracle FS System by its IP address or by the name that is recorded in the domain name system (DNS). When logging in to the Oracle FS System using the ‑u option and the ‑oracleFS option, the fscli application prompts you for a password on the command line interface for access. The Oracle FS System and the account login information are used to authenticate the current session. Establishing a login session by specifying an Oracle FS System and an account does not change the credentials that are associated with the active sessions that are running on other clients.
Caution
Oracle recommends that you not use the Cygwin command line interface to run the fscli application on Windows platforms. If you are running the Cygwin interface and include the ‑u option as a part of the ‑list subcommand, the password for the specified account is included in the results. Exposing the password can cause a breach in security.
