Removing residual configuration files while upgrading to IBM Storage Scale 5.1.x

The gpfs.callhome-ecc-client package is not needed when upgrading to IBM Storage Scale version 5.1.x from an earlier release. This is because the whole Call Home feature is now contained within the base IBM Storage Scale package, gpfs.base.

After the upgrade, some residual configuration files that are not required anymore might still be present on Ubuntu. For example:
root@shortwing-vm1:~# apt list gpfs.callhome-ecc-client
Listing... Done
gpfs.callhome-ecc-client/now 5.0.2-3 all [residual-config]
Use the following command to remove these residual configuration files:
apt --purge remove gpfs.callhome-ecc-client
