DESCRIPTION
nbftconfig is a NetBackup utility that modifies the attributes that are associated with the Fibre Transport (FT) server. It also creates the SAN client entities in the EMM database.
nbftconfig performs the following operations:
Add a new SAN client and its attributes to the EMM database.
Modify an existing SAN client record.
Delete a SAN client.
Add a new FT server.
Modify the attributes of an existing FT server record.
List SAN clients that are defined within the database.
List FT servers that are defined within the database.
List by all active Fibre Channel connections.
List the target port configuration information for FT media servers.
OPTIONS
- -addclient
Adds the specified SAN client to the EMM database. SAN clients are normally automatically discovered when the SAN client code is installed on the client. However, if the notification from the client to the EMM server is lost, use this command to manually add the client. The following attributes can be set by using this command option:
- -C client_name
Specifies the name of the SAN client that is to be added to the database.
- -M master_server
Specifies the master server that is associated with the designated client. If this option is omitted, the local client's master server is used.
- -ftpref preferred | always | fail | never
Determines if the Fibre Channel connections to the media server are preferred (default condition), must always be used, or should never be used. If preferences are not provided, master server defaults are used. This value is set by default according to the global defined for the EMM server. The following describes the possible -ftpref values:
Preferred. Use an FT device if one is available within the configured wait period in minutes. If an FT device is not available after the wait period elapses, NetBackup uses a LAN connection for the operation. If you select this option, also specify the wait period for backups and for restores.
Always. NetBackup always uses an FT device for backups and restores of SAN clients, and waits until an FT device is available before it begins the operation.
Fail. NetBackup fails the job if an FT device is not up and online. If the FT devices are online but busy, NetBackup waits until a device is available and assigns the next job to the device. An FT device may not exist because none is active, none have been configured, or the SAN Client license expired.
Never. NetBackup never uses an FT pipe for backups and restores of SAN clients and uses a LAN connection for the backups and restores.
If you specify Never for the master server, Fibre Transport is disabled in the NetBackup environment, and you can configure FT usage on a per-client basis. If you specify Never for a media server, Fibre Transport is disabled for the media server. If you specify Never for a SAN client, Fibre Transport is disabled for the client.
- -ftrwait minutes
Defines the number of minutes that a restore job should wait for an available Fibre Channel connection before it uses a standard network connection. This option is only valid when the ftpref type is set to preferred.
- -ftwait minutes
Defines the number of minutes that a backup job should wait for an available Fibre Channel connection before it uses a standard network connection. This option is valid only when the ftpref type is set to preferred.
- -np number_of_ports
Defines the maximum number of client ports that can be simultaneously used on a single media server. If the maximum number of client ports is set to 0, then all ports are used. The default number of client ports is 2.
- -deleteclient
Deletes the specified client from the EMM database. The following attribute may be included with this option.
- -C client_name
Specifies the name of the SAN client that is to be deleted from the database.
- -changeclient
Changes the options that are associated with a specific SAN. The following attributes can be set by using this command option:
- -C client_name
Specifies the name of the SAN client that is to be added to the database.
- -ftpref preferred | always | never
Determines if the Fibre Channel connections to the media server are preferred, must always be used, or should never be used. If preferences are not provided, master server defaults are used. This value is set by default according to the global defined for the EMM server.
- -ftwait minutes
Defines the number of minutes that a backup job should wait for an available Fibre Channel connection before it uses a standard network connection. This option is valid only when the ftpref type is set to preferred.
- -ftrwait minutes
Defines the number of minutes that a restore job should wait for an available Fibre Channel connection before it uses a standard network connection. This option is only valid when the ftpref type is set to preferred.
- -rescanallclients
Scans all clients for new FT devices, up to five clients at a time.
- -rescanclient
Scans the specified client for new FT devices. The following attribute can be set by using this command option:
- client_name
Specifies the name of the SAN client to scan.
- -listclients
Displays the list of SAN clients and attributes that are associated with the clients. By default all SAN clients are listed with a subset of attributes. The information output by the listclients operation depends on whether all clients are listed or the attributes associated with a specific SAN client.
The following attributes can be set by using this command option:
- -C client_name
Specifies the name of the SAN client whose information you want listed. If this attribute is omitted, listclients lists the information for all clients that are attached to the designated media server or master server.
- -Me media_server
Specifies the name of the FT server for whose attached clients you want the information listed.
- -M master_server
Specifies the master server that is associated with the FT servers. If this option is omitted, all FT servers are returned.
- -verbose
The output can be displayed in verbose mode and non-verbose mode (by default). When all clients are listed (including all clients by master or media server), the information appears for multi-client, verbose mode output.
The following information appears in verbose mode for the client record:
SAN client name
Version - Client NetBackup software version
State - SAN client state
Master server name
Number of FT servers to which the SAN client can connect
Usage preferences (see addclient)
Usage preference wait period (See addclient)
If a specific SAN client is included in the listclients command, then the information is displayed for that client (single client output):
The following information appears in verbose mode for the client device records:
SAN client device state
Media server name
Media server state
Media server HBA port number on which a device was discovered
Media server HBA port mode
LUN - The LUN that is associated with the HBA Port
The default condition is non-verbose mode output. The output information is the same as for verbose mode in space-separated text format. Client records start with the letter "c" and device records start with the letter "d".
- -deleteserver
Deletes the specified client from the EMM database. The following attribute can be set by using this command option:
- -Memedia_server
Specifies the name of the FT server to be deleted.
- -changeserver
Changes the attributes that are associated with an FT server. The following attributes can be set by using this command option:
- -Me media_server
Specifies the name of the FT server to be changed.
- -M master_server
Specifies the master server that is associated with the designated media server.
- -l connection_limit
Specifies the maximum number of connections that the FT server supports. This number is the total for the server and not per LUN or HBA. If this option is omitted, the FT server's default connection limit is used.
- -state [active | disabled]
Identifies the assigned state of the FT server. The possible values are Active and Disabled.
- -listservers
This operation is used to display the list of FT servers and attributes that are associated with the servers. By default all FT servers are listed:
The following options are associated with the listservers command:
- -Me media_server
Specifies the name of the media server whose attached FT servers are to be listed.
- -M master_server
Specifies the name of the master server whose attached FT servers are to be listed.
- -verbose
Specifies a detailed output for the server information.
The output can be displayed in verbose mode and non-verbose mode (by default). When all clients are listed (including all clients by master or media server), the information appears for multi-client, verbose mode output.
The following output information appears in verbose mode for the server record:
SAN client name
FT Server name
Version - Server NetBackup software version
State -FT Server state
Connection limit
If a specific SAN client is included in the listclients command, then the information is displayed for that client (single client output):
The following output information appears in verbose mode for the client device records:
FT Server HBA port
FT Server HBA port mode
FT Server device state
Associated LUN
FT Connections - number of active FT Connections on the specific HBA/LUN
The default condition is non-verbose mode output. The output information is the same as for verbose mode in space-separated text format. Media server records start with the letter "d" and device records start with the letter "d". Each HBA port number on each server gets a separate line entry in the output.
- -listtargets
This operation is used to display the list of specifics on all the target ports on FT media servers. By default all FT servers are listed.
The following options are associated with the listtargets command:
- -Me media_server
Specifies the name of the media server whose target port configurations are to be listed. If no media server is specified, the target port information is listed for all FT media servers.
- -verbose
Specifies a detailed output for the server information.
The output can be displayed in verbose mode and non-verbose mode (by default). When all clients are listed, the information appears for multi-client, verbose mode output. The default condition is non-verbose mode output. The output information is the same as for verbose mode in space-separated text format.
EXAMPLE 2 shows the use of the nbftconfig -listtargets -verbose command and the output data categories.
- -getconfig
Retrieves the default configuration parameters for the FT server and SAN client attributes.
The following options are associated with the -getconfig command:
- -M master_server
Specifies the master server that is associated with the FT server. If this option is omitted, the master server of the local machine is used.
- -verbose
Specifies a detailed output for the configuration information.
- -setconfig
Sets the configuration parameters for the FT server and SAN client attributes. These attributes can be set by using this command option:
-ftpref preferred | always | never
Determines if the Fibre Channel connections to the media server are preferred, must always be used, or should never be used. This value is set by default according to the global defined for the EMM server.
Usage of -ftpref and -np or -ncp is mutually exclusive.

Defines the number of minutes that a backup job should wait for an available Fibre Channel connection before it uses a standard network connection. This option is required only when the ftpref type is set to preferred.
- -ftrwait minutes
Defines the number of minutes that a restore job should wait for an available Fibre Channel connection before it uses a standard network connection. This option is required only when the ftpref type is set to preferred.
- -ncp number_of_clients_per_target_port
Specifies the maximum number of clients per target port that are allowed on any FT media server.
- -np number_of_ports
Specifies the number of initiator ports on a client that can be used with one FT media server.

Server HBA number
FT Channel - Number of the FT Channel
LUN
Direction
Job Number
The following options are associated with the listactive command:
