Two weeks ago I discovered that in VMware Site Recovery Manager 5.8 it was not possible to configure network mappings when number of port groups was 40+. Instead of list of port groups only thing that was shown was line “Portgroups”. After reducing the amount of port groups to 15 I was able to do the mappings. I reported the error to VMware and today they confirmed that it is now a verified bug. No word on the fix yet.
There is also a thread in VMware forums about this issue: https://communities.vmware.com/thread/491260
Update – VMware has informed me that this bug will be fixed in the next release. No exact ETA but indication that it will be before the end of the year.
Update 2: Site Recovery Manager 18.104.22.168 has been released which fixes the issue.
