VCS clusters running on AIX and utilizing the LVMVG agent must not change the value of NumThreads for the LVMVG agent type from the default value of 1.

To verify the value of the NumThreads attribute of the LVMVG agent type in an existing AIX VCS cluster, run the following command:

# hatype -display LVMVG -attribute NumThreads
#Type        Attribute              Value
LVMVG        NumThreads            1

If any value other than 1 is displayed above, it should be immediately changed as follows:

# haconf -makerw
# hatype -modify LVMVG NumThreads 1
# haconf -dump -makero

Then, verify the change:

# hatype -display LVMVG -attribute NumThreads
#Type        Attribute              Value
LVMVG        NumThreads            1

Operating with the NumThreads attribute set to any value other than 1 for the LVMVG agent may result in unexpected behavior while onlining, offlining, or monitoring LVMVG resources.
