|DEFINE PATH (Define a Path)

| | | | | | |

|

|Use this command to define a path from a source to a destination. |When a path is defined between a source and a destination, the destination is |accessible from that source. You must define the source and destination |before you can define a path.

|Privilege Class

|To issue this command you must have system privilege or unrestricted |storage privilege.

|Parameters |

|source_name (Required)
|Specifies the name of source. |

|When a path is defined between a source and a destination, the destination |is accessible from that source. The source must already be defined to |the TSM server.

|destination_name (Required)
|Specifies the name of the destination. The destination is either a |drive or a library. |

|SRCType (Required)
|Specifies the type of the source. Possible values are: |

|DATAMover
|Specifies that a data mover is the source.

|SERVer
|Specifies that a storage agent is the source. |

|DESTType (Required)
|Specifies the type of the destination. Possible values are: |

|DRive
|Specifies that a drive is the destination. When the destination is |a drive, you must specify a library name.

|LIBRary
|Specifies that a library is the destination. |

|LIBRary
|Specifies the name of the library to which the drive is assigned. |This parameter is required if DESTTYPE=DRIVE. The library and its |drives must already be defined to the Tivoli Storage Manager server. |For path definitions from a NAS data mover to a drive, the drive must be |assigned to a library that has LIBTYPE=SCSI.

|DEVIce (Required)
|Specifies either the name of the device as known to the source, or |FILE if the device is a logical drive in a FILE library.

|The source uses the device name to access the drive or library. See Table 75 for examples. | | | | |
|

|Table 75. Examples of Device Names

Source to destination Example
Storage agent to a drive (not a FILE drive) mt3
Storage agent to a drive when the drive is a logical drive in a FILE library FILE
NAS data mover to a library mc0
NAS data mover to a drive rst0l
|Note:
For information about the device name when the source is a storage agent, see |the Tivoli Storage Manager Managed System for SAN Storage Agent |User's Guide. For information about how to obtain names for |devices that are connected to a NAS file server, consult the product |information for the file server. For example, for a Network Appliance |file server, connect to the file server using telnet and issue the SYSCONFIG |command. Use this command to determine device names for drives:
|sysconfig -t

|Use this command to determine the device name for a library:

|sysconfig -m
|

|ONLine
|Specifies whether the path is available for use. This parameter is |optional. The default is YES. Possible values are: |

|Yes
|Specifies that the path is available for use.

|No
|Specifies that the path is not available for use. |

|The source and the destination must both be available to use the |path. For example, if the path from a data mover to a drive is online, |but either the data mover or the drive is offline, you cannot use the |path.

|Attention: If the path to a library is offline, the server |will not be able to access the library. If the server is halted and |restarted while the path to the library is offline, the library will not be |initialized. See Administrator's Guide for additional |information.

|DIRectory
|Specifies the directory location for a storage agent to access the |files in a FILE library. This parameter is optional. This |parameter is only valid when all of the following conditions are |true: |

|The directory name identifies the location where the storage agent reads |and writes the files that represent storage volumes for the FILE device class |that is associated with the FILE library. The default value for |DIRECTORY is the directory of the server at the time the command is issued, |unless the DSMSERV_DIR environment variable has been set. In most |cases, the default value for DIRECTORY will not be useful because the |directory location can vary among systems accessing the same data on the |SAN.

|Use a naming convention that allows you to associate the directory with a |particular physical drive. This can help ensure that your configuration |is valid for sharing the FILE library between the server and storage |agent. If the storage agent is on a Windows NT or Windows 2000 system, |use a universal naming convention (UNC) name.

|Note:
Tivoli Storage Manager does not create shares or permissions, or mount the |target file system. You must perform these actions before starting the |storage agent. |

|For information about the DSMSERV_DIR variable, refer to Quick |Start. |

|Examples

|Task

|Define a path from the data mover that is a NAS file server to the |drive that the NAS file server will use for backup and restore |operations. In this example, the NAS data mover is NAS1, the drive name |is TAPEDRV3, the library is NASLIB, and the device name for the drive is |rst0l. |

|Command:
|define path nas1 tapedrv3 srctype=datamover desttype=drive |library=naslib device=rst0l |

|Task

|Define a path from storage agent SA1 to the drive that the storage |agent uses for backup and restore operations. In this example, the |library is TSMLIB, the drive is TAPEDRV4, and the device name for the drive is |mt3. |

|Command:
|define path sa1 tapedrv4 srctype=server desttype=drive library=tsmlib |device=mt3 |

|Task

|Define a path that allows the storage agent to access files on disk |storage shared with the Tivoli Storage Manager server. Drive FILE9 is |defined to library FILE1 on the server. The storage agent SA1 accesses |FILE9. The data for FILE9 resides on the server at |d:\tsmdata\filedata. On the storage agent, this data |is on directory c:\tsmdata\filedata. |

|Command:
|define path sa1 file9 srctype=server desttype=drive library=file1 |device=file directory="c:\tsmdata\filedata" |
