We've recently changed a HMC in our LPAR2RRD-config.
To avoid DNS-problems we changed the IP/host-value from an DNS-Entry (same as the current Alias) into an IP-Adresse.
There might be a bug:
the HMC appeared a second time with the IP-adress though we did not change the alias at any time.
Even after changing the host/ip.entry back to the DNS-name it's still here.
Any chance to remove it? Rebuilding GUI did not work.
