The AHDI partition format is usually +only present on disks shared between +.Nx +and some other OS. The partition identifiers are used by +.Nx +as a guideline to emulate a disklabel on such a disk. +.Pp +.Nm ahdilabel +supports the following options: +.Pp +.Bl -tag -width disk +.It Ar disk +The name of the disk you want to edit. +.Nm ahdilabel +will first try to open a disk of this name. If this cannot +be opened, it will attempt to open +.Ar r Ns Ns Ar c . +Finally, if this also cannot be opened, it will attempt to open +.Ar /dev/r Ns Ns Ar c . +.El +.Pp +.Nm ahdilabel +will display information about the number of sectors, tracks +and sectors on the disk, as well as the current AHDI partition information. +It will then prompt for input. The input choices are: +.Pp +.Bl -tag -width a-p +.It Ar a-p +Modify a partition. You will be prompted for a partition id, root, start +and size. +.Nx +recognises the following partition id's: +.Pp +.Bl -tag -width "GEM or BGM" -compact +.It NBD +Partition is reserved for +.Nx . +This can be either a root or an user partition. The first NBD +partition on a disk will be mapped to +.Nx partition +letter +.Em a . +The following NBD partitions will be mapped from letter +.Em d +up. +The filesystem type is ffs by default. +.It SWP +The first SWP partition is mapped to partition +.Em b. +.It GEM or BGM +These partitions are mapped from +.Em d +up. The filesystem type is msdos. +.El +.Pp +The root, start and size parameters can be entered using sector or +cylinder/track/sector notation. Whole numbers of cylinders can be entered +using the shorthand /. Likewise, whole numbers of tracks can be +entered using the shorthand //. +.Pp +The sector holding the primary AHDI partition table only has space for four +partitions. Thus, if a disk has more than four partitions, the extra +partition information is held in auxilliary root sectors. There is one +auxilliary root for each additional partition (and also for the fourth +partition, if the disk has more than four partitions). +.It Ar r +Recalculate the root sectors. This will automatically assign auxilliary +root sectors if the disk has more than 4 partitions. The auxilliary root +sectors will be positioned in a default location preceeding the relevant +partition. +.It Ar s +Show the current partition information. +.It Ar u +Toggle the unit display between sector and cylinder/track/sector notation. +.It Ar w +Write the AHDI partition table to the disk. +.It Ar q +Quit +.El +.Sh EXAMPLES +.Dl ahdilabel sd0 +Edit the AHDI label for disk sd0. +.Sh CAVEATS +The changes made to the AHDI partitions will become active on the next +.Em first open +of the disk. You are advised to use +.Nm ahdilabel +only on a disk without any mounted or otherwise active partitions. This +is not enforced by +.Nm ahdilabel. +.Pp +Because of way +.Nx +interprets AHDI partition tables to create the +.Nx +disklabel, the +.Nx +partition ordering may change if partitions labelled NBD are created or +removed. +.Pp +Creating an AHDI partition table on a disk that previously did not have +one will almost certainly overwrite any existing partition information +and/or data on that disk. This is especially the case if auxilliary root +sectors are needed for the AHDI partition table. +.Pp +As soon as a disk contains at least one NBD partition, you are allowed to +write +.Nx +disklabels and install bootstraps. +.Sh SEE ALSO +.Xr bootpref 8 , +.Xr disklabel 8 , +.Xr installboot 8 +.Sh HISTORY +The +.Nm ahdilabel +command first appeared in +.Nx 1.5 .
