Converting LVM to VxVM

Examples

Example of the vxvmconvert list output which shows the disk devices on a system:

DEVICE DISK GROUP STATUS

c0t5d0 - - online

c0t8d0--LVM

c0t9d0--LVM

c0t10d0 disk01 rootdg online

c0t11d0 - - online

Disk group: rootdg

What does vxmvconvert list display? The device indicates a physical disk, a disk with a name indicates if

the disk is under VxVM control, a group shows the disk group name, and the status indicates if it is an LVM

disk. If the status is online, that means VxVM acknowledges the disk but doesn’t have it under its control.

Example of the vxprint output before conversion:

TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0

dg rootdg rootdg ------

dm disk01 c0t10d0 - 2079468 - - - -

list, listvg outputs are from within the vxvmconvert command. vxprint is a command line command.

Example of the listvg output after conversion of vg08:

LVM VOLUME GROUP INFORMATION

Name Type Physical Volumes

vg00 ROOT c0t5d0

vg09 Non-Root c0t9d0

Volume Group to list in detail: None

NOTE Note that vg08 is no longer listed under LVM information.

Example of the vxvmconvert listvg output after conversion of volume group vg08 to dg08:

DEVICE DISK GROUP STATUS

c0t5d0 - - online invalid

c0t8d0 dg0801 dg08 online

c0t9d0 - LVM

c0t10d0 disk01 rootdg online

c0t11d0 - - online

Disk group: rootdg

Example of the vxprint output after conversion:

TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTILO PUTIL0

dg dg08 dg08 ------

dm dg0801 c0t8d0 - 2080768 - - - -

v dg08lv1 fsgen ENABLED 102400 - ACTIVE - -

pl dg08lv1-01 dg08lv1 ENABLED 102400 - ACTIVE - -

sd dg0801-01 dg08lv1-01 ENABLED 1024000-- - -
