Error Code details
V-5-2-721
Severity: n/a 
Component: Volume Manager 
Message:
The smallest disk in the Volume Group ($vg) does not have sufficient private space for the conversion to succeed. There is only enough private space for $maxrecords VM Database records and the conversion of Volume Group ($vg) would require enough space to allow $totcmds Vm Database records. This would roughly translate to needing an additional $needed_bytes bytes available in the private space. This can be accomplished by reducing the number of volumes in the ($vg) Volume Group, and allowing that for every volume removed, the number of Database records required would be reduced by three. This is only a rough approximation, however.
Description:

Logical volume manager (LVM) volume groups can have multiple disks with different private region sizes. When converting LVM volume groups to volume manager (VM) disk groups, VxVM calculates the private region size for the VM disk groups by selecting the smallest private region size. Before conversion, VxVM ensures that the private region size is sufficient to hold the VM records that are generated as a result of the conversion. If the size is too small, this error message appears.

This error message provides the following information:

  • The number of VM records that can fit into the selected region size
  • The number of VM records that the conversion requires
  • The amount of additional space that the conversion requires

Reduce the number of logical volumes in the LVM volume group.

For every logical volume removed from a volume group, the number of VM records generated during conversion is reduced by three.

You can reduce the number of logical volumes in a volume group by putting some of them into another volume group. (That is, you can use two volume groups instead of one.)

To create a second volume group and move some of the logical volumes into it:

  1. Create a new volume group on a new disk using the following command:
    mkvg –y new_volume_group … new_disk
  2. Copy one of the existing logical volumes to the new volume group using the following command:
    cplv –v new_volume_group –y new_logical_volume source_logical_volume
  3. Repeat the command in Step 2 until you have copied the desired number of existing logical volumes to the new volume group.
  4. Remove the original logical volumes that you copied in Step 2 from the original volume group using the following command:
    rmlv source_logical_volume
