- ATTACHDEVICE: HI Command Common Alias: AD
- Attaches a physical device to the operating system and
- associates a logical name with the device. Attachdevice
- catalogs the logical name in the root object directory,
- making the logical name accessible to all users.
-
- SYNTAX:
- attachdevice physical-name as :logical-name: [n[ d]|p|r|e] [w]
-
- PARAMETERS:
-
- physical-name
- Physical device name of the device to be
- attached to the system. This name must be the
- name used in a BIOS Device Unit Information
- Block (DUIB), as defined at system
- configuration time.
-
- as
- Preposition required for the command.
-
- logical-name
- A 1 to 12 character name (excluding colons) to be
- associated with the device. Colons surrounding
- the logical name are optional, but if used must
- be in pairs (:logical-name:).
-
- n(amed)
- The volume mounted on the device is already
- formatted for the iRMX named file driver.
- Volumes that can contain named files are
- diskettes or hard disks. If named, physical,
- remote, or edos is not specified, named is the
- default.
-
- d(elay)
- The device is attached logically, but not
- physically attached until the first access.
-
- p(hysical)
- The volume mounted on the logical device is
- considered to be a single, large file. Examples
- include printers, terminals, and tape drives.
-
- r(emote)
- The volume mounted on the logical device is a
- remote file server. If you specify remote with
- the physical name of a remote server, a logical
- name is created for the virtual root directory
- of the server. The logical name is used to
- transparently access files residing at the
- server. The server, rather than the consumer,
- associates the appropriate device drivers with
- the devices residing at the server system. As a
- result, consumer systems do not require DUIBs
- attached for remote servers. The world switch
- is always supported for consumer-based
- connections and is supported for server-based
- connections if the remote server has defined a
- user named World with a carriage return password.
-
- e(dos)
- For iRMX for Windows, specifies the encapsulated
- DOS (EDOS) file driver, allowing iRMX users to
- access shared DOS files. The edos parameter
- includes the delay and world parameters.
- Physical device names used with this parameter
- include a_dos through z_dos, which are equivalent
- to DOS drives A: through Z:.
-
- w(orld)
- The World user (ID 65535) is the owner of the
- device. Any user can detach the device. If you
- omit this parameter, your user ID is listed as
- the owner of the device. In this case, only you
- and the system manager can detach the device.
- In iRMX for Windows, access to an edos device is
- always done as World.
-
- ADDITIONAL INFORMATION:
-
- To use a device you must attach it, unless it is attached
- by the system during initialization. For example, before
- you use the format, backup, or restore commands, you must
- attach the appropriate device. Likewise, any time you put
- a diskette in its drive, you must attach the drive device.
- For general access of a hard disk or diskette, such as
- reading or writing files, you may attach the device under a
- generic physical device name. However, to format a hard
- disk or diskette, you must attach it under a specific
- physical (DUIB) name that specifies the device
- characteristics.
-
- For further information on using the Attachdevice command,
- please refer to the Command Reference manual.
