VXVMCONVERT (1M) |
Maintenance Commands |
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 vxvmconvert 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 databases, 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.
See the ``Limitations in Conversion'' section in the Volume Manager Migration Guide for more information.
See to the section ``Tailoring your VxVM Configuration'' in the Volume Manager Migration Guide for more information.
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 information.
