Data VxVM disk/lun grow
hi,
i have a volume on a LUN of an EMC-storage and i need to increase the
size.
i could increase the size of the LUN on the EMC, i could increase the
size of the disk for solaris, but how can i tell the veritas volume
manager that the disk is larger now?

what i've done:

1. LUN on EMC
2. in the format menue i' ve chosen the type to autoconfigure, i can see
the bigger disk in solaris, then in the partitions menu i've created the
VTOC like before, only one slice on 7 (and 2 for backup, like before) for
the whole space.
but VxVM still means
# vxassist -g datadg maxsize
VxVM vxassist ERROR V-5-1-752 No volume can be created within the given
constraints
# vxassist -g datadg maxgrow datavol
VxVM vxassist ERROR V-5-1-1178 Volume datavol cannot be extend within the
given constraints

so i tried "vxdctl enable", but still the same... but i can still work
with the volume.. it must be written in the privatregion somewhere...
any ideas?

V440, solaris9 (09/05), VxVM 4.1, VxFS 4.1

thanks in advance,
PRESSY

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

	 Disk c4t15d0s2 is now a broken off root disk

       The  next  example  shows  the  command being executed on a disk that does not contain a valid root mirror, and which requires vxrootmir be
       called to mirror the root disk first:
