volrmmount(1)							   User Commands						     volrmmount(1)

NAME
volrmmount - call rmmount to mount or unmount media SYNOPSIS
volrmmount [-i | -e] [name | nickname] volrmmount [-d] DESCRIPTION
The volrmmount utility calls rmmount(1M) to, in effect, simulate an insertion (-i) or an ejection (-e). Simulating an insertion often means that rmmount will mount the media. Conversely, simulating an ejection often means that rmmount will unmount the media. However, these actions can vary depending on the rmmount configuration and media type. For example, using default settings, if you insert a music CD, it might not be mounted. However, you can configure rmmount so that it calls workman whenever a music CD is inserted. This command allows you to override volume management's usual handling of media (see EXAMPLES below). OPTIONS
The following options are supported: -i Simulates an insertion of the specified media by calling rmmount. -e Simulates an ejection of the specified media by calling rmmount. -d Displays the name of the default device for volrmmount to handle. This device is used if no name or nickname is supplied. OPERANDS
The following operands are supported: name The name that volume management recognizes as the device's name. nickname A shortened version of the device's name. Following is the list of recognized nicknames: +-----------------------------+-----------------------------+ | Nickname | Path | +-----------------------------+-----------------------------+ |fd |/dev/rdiskette | +-----------------------------+-----------------------------+ |fd0 |/dev/rdiskette | +-----------------------------+-----------------------------+ |fd1 |/dev/rdiskette1 | +-----------------------------+-----------------------------+ |diskette |/dev/rdiskette | +-----------------------------+-----------------------------+ |diskette0 |/dev/rdiskette0 | +-----------------------------+-----------------------------+ |diskette1 |/dev/rdiskette1 | +-----------------------------+-----------------------------+ |rdiskette |/dev/rdiskette | +-----------------------------+-----------------------------+ |rdiskette0 |/dev/rdiskette0 | +-----------------------------+-----------------------------+ |rdiskette1 |/dev/rdiskette1 | +-----------------------------+-----------------------------+ |floppy |/dev/rdiskette | +-----------------------------+-----------------------------+ |floppy0 |/dev/rdiskette0 | +-----------------------------+-----------------------------+ |floppy1 |/dev/rdiskette1 | +-----------------------------+-----------------------------+ |cdrom0 |/dev/rdsk/cXtYdZ/label | +-----------------------------+-----------------------------+ |zip0 |/dev/rdsk/cXtYdZ/label | +-----------------------------+-----------------------------+ |jaz0 |/dev/rdsk/cXtYdZ/label | +-----------------------------+-----------------------------+ |rmdisk0 |/dev/rdsk/cXtYdZ/label | +-----------------------------+-----------------------------+ EXAMPLES
Example 1 Using the volrmmount command When volume management finds a floppy that contains a filesystem, it calls rmmount to mount it. If you wish to run tar(1) or cpio(1) on that floppy, it must first be unmounted. To unmount the floppy use: example% volrmmount -e floppy0 After volrmmount unmounts the floppy, if you wish to re-mount it (rather than ejecting it and reinserting it) use: example% volrmmount -i floppy0 Notice that if you are using a named floppy, you can use its name in place of floppy0.

/dev/volctl volume management control port ATTRIBUTES
