Scenario1:
VG00 lvm,not mirrored,2 disk of 36GB vg size
VG00 size is under 30G.
Is possible to remove a disk of 36GB and replace "on fly"
with a disk of 300GB on VG00?

Hi All,
How do you know if you need to break the mirror on solaris 8 patch update?
Here's the patch example, 117350-54. On the site, it's just a low type update and not a medium or critical.
Is breaking a mirror a best practice only or really a requirement to some patch?
Thanks,

NAME
vxvmconvert - convert LVM volume groups to VxVM disk groups
SYNOPSIS
vxvmconvert
DESCRIPTION
vxvmconvert is a menu-driven program to convert an HP Logical Volume Manger (LVM) configuration to a Veritas Volume Manager configuration.
This man page is a brief overview of vxvmconvert. Refer to the Veritas Volume Manager Migration Guide for a detailed description before
using the conversion procedure.
The vxvmconvert script is interactive and prompts you for responses, supplying defaults where appropriate. There is a Help facility at
every prompt. Enter a question mark (?) at a prompt to display a context-sensitive help message.
With vxvmconvert you can identify LVM volume groups, list disks, analyze volume groups for conversion and complete the conversion of LVM
volume groups to VxVM disk groups.
LVM configurations are converted at the volume group level. All disks used in a volume group are converted together. You cannot use vxvm-
convert to convert unused LVM disks (those not part of an LVM volume group) to VxVM disks. To convert unused LVM disks, use pvremove to
take the disk out of LVM control, then initialize the disk for VxVM use by using vxdiskadm (see pvremove(1M) and vxdiskadm(1M) for more
information).
vxvmconvert changes disks within LVM volume groups to VxVM disks by replacing the areas of the disks used for LVM configuration information
and with the equivalent VxVM volume configuration information. Portions of the disks used for user data, such as file systems and data-
bases, are not affected by the conversion.
The conversion process changes the names by which your system refers to the logical storage, so must be done offline. No applications can
access data in the volume groups undergoing conversion. You must unmount file systems using those volumes and shut down any applications,
such as databases, that might use the volumes directly.
OPERATIONS
Analyze LVM Volume Groups for Conversion
Use this operation to analyze one or more LVM volume groups for conversion to use by VxVM. The analysis checks for problems that
can prevent the conversion from completing successfully. It calculates the space required to add volume group disks to a Volume
Manager disk group. More than one volume group may be entered at the prompt. A grep-like pattern may be used to select multiple
volume groups.
See the ``Limitations in Conversion'' section in the Volume Manager Migration Guide for more information.
Convert LVM Volume Groups to VxVM
Converts one or more LVM volume groups to one or more VxVM disk groups. This adds the disks to a VxVM disk group and replaces
existing LVM volumes with VxVM volumes.
vxvmconvert prompts you to name the VxVM disk group that replaces the LVM volume group being converted. A default is suggested
at the prompt. For example, if you are converting a volume group vg08, vxvmconvert renames it as dg08.
See to the sections ``Dealing with New Logical Volume Names'' and ``Tailoring your VxVM Configuration'' in the Volume Manager
Migration Guide for more information.
Rollback from VxVM to LVM
Rollback reverts VxVM disk groups to LVM volume groups. vxvmconvert provides a limited snapshot capability for the LVM metadata
in a converted volume group. A snapshot is a simple protection method to use during conversion.
Caution! Do not use this operation if the VxVM disk group was modified since the conversion.
See to the section ``Restoring LVM Volume Groups and Disaster Recovery'' in the Volume Manager Migration Guide for more informa-
tion.
List Disk Information
Displays information about the disks on a system. You can obtain detailed information about a disk by entering a specific disk
device address.
List LVM Volume Group Information
Listvg displays a list of LVM volume groups. You can obtain detailed information about an LVM volume group at a specific disk
device address.
