\b0 is a daemon started by the /etc/rc script and used by the Workspace Manager to automatically mount and initialize optical disks when they are inserted into an optical drive. All of the user interaction is handled by the Workspace Manager. If an optical disk is inserted when autodiskmount is not running the disk is ejected. To allow a UNIX program to use an optical disk that hasn't been inserted yet, first run the program and wait for an alert panel to appear instructing you to insert the disk. If an optical disk is already inserted into an optical drive when the system is booted, but that disk is not the root device, then autodiskmount will automount it when the Workspace Manager starts up after you login.

A swapdisk is defined as a disk with a valid label whose first 8 characters are "swapdisk". The remainder of the disk label is irrelevent (for example, a disk whose label is "swapdisk2" would be considered a swapdisk). The results of are returned via an exit code.

\f0\b0\i0\ulnone\ql\fs24\fi0\li0\gray0\fc0\cf0\up0\dn0 The raw disk device to be checked
\b0 displays the amount of disk space occupied by currently mounted file systems, the amount of used and available space, and how much of the file system's total capacity has been used. Used without arguments, df reports on all mounted file systems, producing something like:\
Note that used+avail is less than the amount of space in the file system (kbytes); this is because the system reserves a fraction of the space in the file system to allow its file system allocation routines to work well. The amount reserved is typically about 10%; this may be adjusted using tunefs. When all the space on a file system except for this reserve is in use, only the super-user can allocate new files and data blocks to existing files. When a file system is overallocated in this way, df may report that the file system is more than 100% utilized.\
If arguments to df are disk partitions (for example, /dev/ip0a) or UNIX path names, df produces a report on the file system containing the named file. Thus "df ." shows the amount of space on the file system containing the current directory.

\b disk
\b0 utility program can be used to initialize, inspect, repair, and configure optical, floppy and SCSI disks.\
The option flags are used with the -i action flag to specify certain parameters when initializing a disk:\
-h hostname Specifies a hostname to be stored in the disk label. The actual hostname of a machine is not determined by the disk label, but in the case of removable optical media this field may be set for informational purposes to indicate which machine the disk belongs to.\
-l labelname The labelname of a disk is printed in the message log when the system boots. For optical media this is also the name used as the mount point in the / directory when the disk is automounted.\
-t disk_type The disk configuration information in /etc/disktab is named by an identifier called the disk type. By default, when the disk program is run it will attempt to determine the proper disk type to use. Use this flag to override the default. This is used to reinitialize a disk using a different set of configuration parameters from /etc/disktab (e.g. a different number and/or size of filesystem partition(s)).\
The action flags are used to perform a specific command in the disk program (only one may be specified):\
-i This flag will initialize a disk including writing out a new disk label containing information about the host name, label name and information found in /etc/disktab. A boot program will be installed onto the boot block area of the disk from the file /usr/standalone/boot. If specified in the configuration information in /etc/disktab, the initialize flag will also build empty UNIX filesystems on the disk. The initialize flag will destroy all data on the disk. WARNING: Don't initialize a mounted device. Example: "/etc/disk -h myhost -l mydisk -i /dev/rod0a"\
-e This flag will eject ejectable media. No attempt is made to unmount the filesystems on this disk before ejecting.\
-b The boot program in /usr/standalone/boot will be written onto the boot block area of the disk.\
-B Same as -b, except that it takes as an argument the pathname of the file containing data to be written onto the boot block area of the disk.\
-p partitionsize The first partition of a two-partition disk will be partitionsize, and the second partition uses the remainder of the disk. The partitionsize is in units of the native blocksize of the device (minimum 1K). The -p option only has meaning when used with -i.\
-q The default disk type information returned by the device driver for this disk will be printed. This flag is used by the Builddisk application to determine what kind of disk is present.\
-s If the device driver keeps any special statistics for the disk they will be printed with this flag.\
-F This flag formats the disk.\
-H hostname This flag can be used to change the hostname field of the disk label without disturbing other fields in the label.\
-L labelname This flag can be used to change the labelname field of the disk label without disturbing other fields in the label.\
If no action flags are specified the program operates in an interactive mode. In interactive mode type the interrupt character at any time to abort the current command. Typing '?' will list the available commands. Many of the commands will prompt for additional arguments or sub-commands. There are many interactive commands in addition to the ones described by the option flags above:\
read, write, verify, rw, rwr These commands will read, write and verify data on the disk. All block numbers used in these commands are absolute disk block numbers and do not correspond to block numbers reported from the filesystem. No bad sector forwarding or additions are performed with these commands. On an optical disk, these commands can be used to write a sector that has become unreadable due to an uncorrectable ECC errors. WARNING: These commands may destroy disk data.\
look, set These commands may be used to inspect and modify the data buffers used in the read and write commands described above.\
abort This command toggles whether an error will stop the read and write commands described above.\
label This command is used to print and change information in the disk label. To change only the hostname or labelname fields use the -H hostname or -L labelname action flags described earlier.\
bad Use this command to display and edit the bad block table maintained on optical disks.\
bitmap Use this command to display and edit the sector status bitmap maintained on optical disks.\
scan The scan command sequentially searches the disk for file system super blocks and prints the file system block number where they are found. This information is essential if the primary super block of a file system is damaged and one needs to specify an alternate super block location to the file system check program fsck but one does not know which block number to specify. (e.g. "fsck -bnnn /dev/rod0a" where "nnn" is the block number of the alternate super block). A list of these block numbers is produced when a file system is initialized with the newfs command, but this list usually isn't around when needed.

\b mount
\b0 command attaches a filesystem fsname to the file tree at the directory dir. This form prints the list of mounted filesystems.\
The mount and umount commands maintain a table of mounted filesystems in /etc/mtab, described in mtab(5). The mount command mounts entries onto the filesystem from data it finds in one of two places. If NetInfo is running, it comes from netinfo(5). Otherwise, the entries are stored in /etc/fstab(5). Note that boot time mounts of type "4.3" filesystems always occur before NetInfo is running, and so must be stored in /etc/fstab to be seen by the system. If invoked without an argument, mount displays the table from /etc/mtab. If invoked with only one of fsname or dir mount searches the filesystem table for an entry whose dir or fsname field matches the given argument. For example, if this line is in /etc/fstab:\
\b /dev/sd1a /usr 4.3 rw 1 1

The actual relocation and reassignment is performed by the disk drive (as opposed to the operating system). The algorithms used to allocate spare sectors vary between drive manufacturers. SCSI_block_number is generally obtained from console error information, printed by the SCSI disk driver upon detection of media errors reported by the drive during normal operation.

If any one read attempt is successful, the reassignment takes place and then the previously read contents of SCSI_block_number are written back to the newly relocated sector. If all 20 read attempts result in errors, the user will be notified and asked whether or not to continue with the reassign block command. Responding with anything other than 'y' results in the operation being aborted with no further I/O
\b0 is an RPC server that answers file system mount requests. It reads the file /etc/xtab, described in exports(5), to determine which file systems are available for mounting by which machines. It also provides information as to what file systems are mounted by which clients. This information can be printed using the showmount(8) command.\
The mountd daemon is normally invoked by rc(8).

\b0 executes a Format Unit Command on raw_device. raw_device must be a SCSI disk. This is normally invoked by the disk(8) program when initializing a new floppy disk; however, it may be used to re-initialize a damaged floppy or hard disk. sdform should be used with extreme caution; all data on the disk being formatted is lost.

\b0 lists all the clients that have remotely mounted a filesystem from host. This information is maintained by the mountd(8C) server on host, and is saved across crashes in the file /etc/rmtab. The default value for host is the value returned by hostname(1).
