DESCRIPTION

You sever the association between LUNs and hosts by removing host maps. When you remove a host map, you have the option of removing all host maps associated with that host in a single operation or in multiple operations.

Two methods are available to delete any host maps that are associated with a LUN or a set of LUNs.

Delete the LUN and all its associated mappings in one operation by using the lun ‑delete command. Answer “yes” to all verification questions appearing on the command line.
Remove the host mappings that are associated with a given LUN or a given set of LUNs by using the hostmap ‑delete command.

The following options are mutually exclusive (only one must be selected):

‑host
‑hostmap
‑hostGroup
‑hostGroupMap

Note: Only administrators with primary administrator, admin1, or admin2 roles are authorized to run the hostmap ‑delete command.

OPTIONS

‑host

Specifies a host entry which represents a computer on the customer SAN. You identify a host by providing a unique ID (ID) or a fully qualified name (FQN) for the host entry.

To delete the entries for multiple hosts, provide a comma-separated list of hosts.

‑hostGroup

Specifies a group of computers on the customer SAN. You identify the host group by providing a unique ID (ID) or a fully qualified name (FQN) for the group.

To delete the mappings for multiple host groups, provide a comma-separated list of host groups.

‑hostGroupMap

Specifies a mapping between a LUN and a host group. You identify the host group mapping by providing a fully qualified name (FQN) or a unique ID (ID).

To delete the LUN mappings for multiple host groups, provide a comma-separated list of host group maps.

‑hostmap

Identifies a mapping between a LUN and a SAN host. You identify the hostmap by providing a unique ID (ID) or a fully qualified name (FQN).

To delete multiple hostmaps, provide a comma-separated list of hostmaps.

‑lun

Specifies the ID or the fully qualified name (FQN) of a LUN that resides on the Oracle FS System. An FQN begins with a forward slash character ( / ) and is followed by a path expression to locate the LUN.

The ‑lun option specifies one or more LUN or Clone LUN entries that are contained in the host maps for the specified host or host group to delete. If the ‑lun option is omitted, all of the host maps for the given host or host group are deleted.

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.
