Error Code details
V-5-1-6646
Severity: Error 
Component: Volume Manager 
Message:
Length of volume %s would not be a multiple of the disk group alignment.
Description:

If you change the alignment of a disk group, Veritas Volume Manager (VxVM) verifies that if the following object offsets or lengths in the disk group are compatible with the new alignment. If the attribute of some objects is not a multiple of the new disk group alignment, VxVM fails to set new alignment value for the disk group and the message is displayed.

 
Objects:
  • Volume length
  • Volume log length
  • Disk Media length of opaque disks 
  • Subdisk length
  • Plex stripe width
  • Subdisk plex offset
  • Subdisk offset

To solve the issue, do the following: 

  1. Get the current disk group alignment value with the following command:
    # vxdg  list diskgroup_name | grep alignment
  2. Use the vxcdsconvert(1m) command to make the disk group portable, for example by moving subdisks to a different location so that they conform to the Cross-platform Data Sharing (CDS) alignment restriction. 
    # vxcdsconvert -g diskgroup_name alignment
For more information about the vxcdsconvert(1m) command, see manual pages on the SORT website.
