There is a way of change the hostname of a device in UMP? Or a way of set a 'alias' ?
CA UIM 8.2
CA UMP 8.2
In 8.2 it's not possible unfortunately, but in 8.31 and above USM has the ability to set a display alias.
I don't know the impact of this, but You can change the hostname through update sql query. So be careful.
