SVHLABEL(8)             NetBSD System Manager's Manual             SVHLABEL(8)

NAME
     svhlabel -- update disk label from SGI Volume Header

SYNOPSIS
     svhlabel [-fqrw] device

DESCRIPTION
     svhlabel is used to update a NetBSD disk label from the Silicon Graphics
     Volume Header on disks that were previously used on IRIX systems.

     svhlabel scans the Volume Header contained in the first blocks of the
     disk and generates additional partition entries for the disk from the
     entries found.

     Each Volume Header entry which does not have an equivalent partition in
     the disk label (equivalent in having the same size and offset) is added
     to the first free partition slot in the disk label.  A free partition
     slot is defined as one with an fstype of `unused' and a size of zero
     (`0').  If there are not enough free slots in the disk label, a warning
     will be issued.

     The raw partition (typically partition c, but d on i386 and some other
     platforms) is left alone during this process.

     By default, the proposed changed disk label will be displayed and no disk
     label update will occur.

     Available options:

     -f  Force an update, even if there has been no change.

     -q  Performs operations in a quiet fashion.

     -r  In conjunction with -w, also update the on-disk label.  You probably
         do not want to do this.

     -w  Update the in-core label if it has been changed.
