convert command transforms volume layouts between layered and non-layered forms:
vxassist [-b] [-g
If specified, the
-b option makes conversion of the volume a background task.
The following conversion layouts are supported:
Volume conversion can be used before or after performing online relayout to achieve a larger number of transformations than would otherwise be possible. During relayout process, a volume may also be converted into a layout that is intermediate to the one that is desired. For example, to convert a volume from a 4-column mirrored-stripe to a 5-column mirrored-stripe, first use
relayout to convert the volume to a 5-column striped-mirror as shown here:
vxassist -g mydg relayout vol1 ncol=5
When the relayout has completed, use the
vxassist convert command to change the resulting layered striped-mirror volume to a non-layered mirrored-stripe:
vxassist -g mydg convert vol1 layout=mirror-stripe
If the system crashes during relayout or conversion, the process continues when the system is rebooted. However, if the crash occurred during the first stage of a two-stage relayout and convert operation, only the first stage will be completed. You must run
convert manually to complete the operation.
