|
||||
.Sh SYNOPSIS
|
||||
.Nm edahdi
|
||||
.Ar device
|
||||
.Sh DESCRIPTION
|
||||
.Nm edahdi
|
||||
Allows you to modify the partition identifiers on a disk partitioned with
|
||||
AHDI or an AHDI compatible formatter. An AHDI partition format is usually
|
||||
only present on disks shared between NetBSD and some other OS. The partition
|
||||
identifiers are used by NetBSD as a guideline to emulate a disklabel on such
|
||||
a disk.
|
||||
.Pp
|
||||
.Nm edahdi
|
||||
supports the following options:
|
||||
.Pp
|
||||
.Bl -tag -width device
|
||||
.It Ar device
|
||||
The name of the raw device you want to edit.
|
||||
.El
|
||||
.Pp
|
||||
The following partition identifiers are recognized by NetBSD:
|
||||
.Pp
|
||||
.Bl -tag -width "GEM or BGM" -compact
|
||||
.It NBD
|
||||
Partition is reserved for NetBSD. This can be either a root or an user
|
||||
partition. The first NBD partition on a disk will be mapped to partition
|
||||
.Em a
|
||||
in NetBSD. The following NBD partitions will be mapped from
|
||||
.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.
|
||||
.It NBR
|
||||
NetBSD root partition (depricated).
|
||||
.It NBU
|
||||
NetBSD user partition (depricated).
|
||||
.It NBS
|
||||
NetBSD swap partition (depricated).
|
||||
.El
|
||||
.Sh EXAMPLES
|
||||
Say, you have a disk with that is partitioned like:
|
||||
.Pp
|
||||
.Bl -column header Number Id
|
||||
.Sy "Number Id"
|
||||
1 GEM
|
||||
2 GEM
|
||||
3 GEM
|
||||
4 GEM
|
||||
.El
|
||||
.Pp
|
||||
This partitioning will show up in NetBSD as (Number refers to the first table):
|
||||
.Pp
|
||||
.Bl -column header "Partition Fstype Number"
|
||||
.Sy "Partition Fstype Number"
|
||||
c (whole disk) unused
|
||||
d (user part) MSDOS 1
|
||||
e (user part) MSDOS 2
|
||||
f (user part) MSDOS 3
|
||||
g (user part) MSDOS 4
|
||||
.El
|
||||
.Pp
|
||||
Now you decide to change the id of partition 2 and 3 to NBD. Now NetBSD
|
||||
will show the partitioning as (Number refers to the first table):
|
||||
.Pp
|
||||
.Bl -column header "Partition Fstype Number"
|
||||
.Sy "Partition Fstype Number"
|
||||
a (root) 4.2BSD 2
|
||||
c (whole disk) unused
|
||||
d (user part) MSDOS 1
|
||||
e (user part) 4.2BSD 3
|
||||
f (user part) MSDOS 4
|
||||
.El
|
||||
.Pp
|
||||
You will notice that the order of the partitions has changed! You will have
|
||||
to watchout for this. It is a consequence of NetBSD habit of assigning a
|
||||
predefined meaning to the partitions
|
||||
.Em a/b
|
||||
and
|
||||
.Em c .
|
||||
.Sh CAVEATS
|
||||
The changes made to the AHDI partitions will become active on the next
|
||||
.Em first open
|
||||
of the device. You are advised to use
|
||||
.Nm edahdi
|
||||
only on a device without any mounted or otherwise active partitions. This
|
||||
is not enforced by
|
||||
.Nm edahdi.
|
||||
This is particularly confusing when your change caused partitions to shift,
|
||||
as shown in the example above.
|
||||
.Pp
|
||||
As soon as a disk contains at least one NBD partition, you are allowed to
|
||||
write disklabels and install bootstraps.

|

.Nm edahdi
|
||||
command first appeared in NetBSD 1.1B
