Method error when running cfgmgr

If you see the following error when running cfgmgr:

Method error (/usr/lib/methods/fcmap >> /var/adm/essmap.out):
        0514-023 The specified device does not exist in the
                 customized device configuration database.
This is caused when you have ESS driver filesets installed, but no ESS (type 2105) disks in use on the system. Check the type of disks by running:
# lsdev -Cc disk | grep 2105
If no type 2105 disks are found, you can uninstall any ESS driver filesets:
# installp -u ibm2105.rte ibmpfe.essutil.rte
