    Update: The issue was the GTM monitoring...setting it to the iquery(bigip) would mark it offline. Thus, it was set for icmp. 0n the DC1 pair, 02 didn't have the same CAs as 01. Once I imported the CAs, I was able to set the monitoring to iquery. Works now.

Does your server in DC1 host only VS1 and no other Virtual servers ? 

If yes , try to disable the whole server ( whatever bigip or Generic host )

        Hi Sonny , 
        I checked F5 bug scrub tracker , but I didn't find bug related to your issue. 

        I would recommend >>> 
        Try to install your UCS in a test environment bigip lab , and try to disable the VS and check the pool member status. 

        or try to upgrade to v15.1.x latest point release , maybe you are hitting in unidentified bug for v13.1.5.
