vxbrk_rootmir
vxbrk_rootmir(1M) vxbrk_rootmir(1M)
NAME
vxbrk_rootmir - break off a mirror of a VxVM root disk to create a separate root disk generation
SYNOPSIS
/etc/vx/bin/vxbrk_rootmir [-g diskgroup] [-v] [-b] [-t tasktag] {daname|dmname}
DESCRIPTION
The vxbrk_rootmir command creates a mirror of a Veritas Volume Manager (VxVM) rootable boot disk, breaks the mirror, and then makes the
broken-off mirror into a completely separate root disk that is suitable for booting by itself.
Except the specified target disk, the bootdg should not contain any disks other than valid root mirror disks. A valid root mirror disk
should have mirrors of all volumes in the bootdg. Thus, all disks must be exactly identical in terms of the volumes contained.
The given disk access name, daname, or disk media name, dmname, is first checked to see if it is already a valid root disk mirror. If so,
the mirror is broken off from the current VxVM root disk, and regenerated into a unique VxVM root disk. If the specified disk is not a
valid root disk mirror, and is unused for other purposes, the vxrootmir command is first called to mirror the specified disk from the cur-
rent VxVM root disk. After the mirroring operation is complete, the mirror is then broken off, and regenerated into a unique VxVM root
disk.
OPTIONS
-b Uses the setboot command to set the alternate boot disk to the specified disk. If the -v option is also specified, information is
displayed about the current setboot settings.
-g diskgroup
Specifies the disk group into which the newly broken-off mirror is to be placed. The disk group is created if it does not already
exist. If the disk group already exists, the broken-off mirror is added to it. If this option is not specified, the disk group of
the broken-off mirror is set to the current default disk group. However, the generation number is made different from the default disk
group to prevent the mirror from being automatically imported.
-t tasktag
Marks any tasks that are registered to track the progress of an operation with the specified tag, tasktag. This option is passed to
vxrootmir if it is necessary first to mirror the specified disk that is to be broken off.
-v Displays verbose output, including timestamps for operations that are in progress. This option is passed to vxrootmir if it is neces-
sary first to mirror the specified disk that is to be broken off.
ARGUMENTS
daname Specifies the disk to be used as the broken off mirror by its disk access name (such as c0t2d0).
dmname Specifies the disk to be used as the broken off mirror by its disk media name (such as rootdisk03).
EXAMPLES
This example shows the vxbrk_rootmir command being executed on a disk that already contains a valid root mirror:
/etc/vx/bin/vxbrk_rootmir -g brkdg -vb c4t15d0

called to mirror the root disk first:
