Display and print fix cover letters. To view the server
firmware fix cover letter, you need to identify the PTFs that correspond to
the server firmware fixes. PTFs for server firmware fixes are displayed with
the Licensed Internal Code product (5722999) and begin with the prefix
MH.
For example,
MHnnnnn where
nnnnn is the number
associated to the specific server firmware fix.
