I noticed that when I have installed SP03 on PowerHA7.1 there is a kind of bug under smit menu Communications Applications and Services: You can see PowerHA SystemMirror submenu three times.
Not really important, it works either way. I just expected to see it fixed in next SP.
I have installed SP4 on PowerHA nodes yesterday.
Now, there is no three times same submenu.
It is four times now.
