Unable to create a layered volume

Problem

The following command fails:

# vxassist -g testdg make testvol 10g layout=concat-mirror

Error Message

VxVM vxassist WARNING V-5-1-3111 Can not convert to desired layout
Creating non-layered volume

Cause

Comment from the source code.

* This function is for generic disk array support. Some operations are
* valid and supported for volumes based on disks from certain disk arrays,
* Currently, volumes based entirely on EMC Symmetrix disk arrays can be
*  mirrored, grown, but not relayout or convert to layered volume.
 

 

 

Solution

The vxassist command will create a non-layered volume instead.

Creating a layered volume on an EMC Symmetrix is not supported.


Applies To

All disks are EMC Symmetrix
