My experience has been this: When you click the "renew" button in LTM 11.5.4, the SAN field is blank. You need to paste in all of the SAN names and any new names you are adding in the correct format. This will generate a .csr file which can be presented to your cert provider.

 

The correct format for the SAN field is:

 

DNS:name1.domain.com, DNS:name2,domain.com, DNS:fubar.flop.com, DNS:
