vxvmconvert.
To unmount a file system, use the following command:
# umount filesystem
Conversion and Reboot During conversion, after the analysis phase
is complete, the disks to be converted are deemed to be conversion ready.
The vxvmconvert program asks if you are ready to commit to the
conversion changes. If you choose to complete the conversion, the system
will try to unmount all of the associated mounted file systems, stop and
export the volume group, and then install the VxVM configuration.
If vxvmconvert is unable to stop and export volume groups or unmount
file systems, the conversion cannot be completed without rebooting the
system. You will have the option of aborting the conversion or completing
the conversion by rebooting the system. If you choose to reboot,
vxvmconvert will trigger the completion of the conversion automatically,
during reboot, when it can be guaranteed that no processes have access
to the volumes that are being converted.
If you choose to abort rather than reboot to complete the conversion,
vxvmconvert will return to the main menu.
NOTE The LVM logical volumes to be converted must all be available to the
vxvmconvert process. You should not deactivate the volume group or any
logical volumes before running vxvmconvert.
To Activate a Volume Group If you are not certain if the LVM
volumes or the corresponding volume groups are active, you can activate
them with the following command:
# vgchange -a y vol_grp_name
7. Converting a volume group
To do the actual conversion of LVM volume groups to VxVM disk groups,
choose option 2 of the vxvmconvert utility.
vxvmconvert will prompt for a name for the VxVM disk group that will
be created to replace the LVM volume group you are converting. This is
