Network replacement system
I'm a semi-noob
We had our primary BIG IP LTM (version 10.2 build 1789) fail and the standby system (unit 2) properly took over. We received the new system and the hotfixes were applied to bring it to 1789. Unfortunately didn't have a proper saved ucs archive so we configured from scratch essentially duplicating the information from unit 2 except entering the unique IPs (external, internal, and peer) for unit 1.
Once unit 1 was configured it did not have any network connectivity to *anything* (except my laptop on the mgmt interface and serial console). It cannot ping the upline switch it is connected too or unit 2 or a mgmt box on the same internal network. I started over and stripped everything out of the configs. When the DB-9 cable connecting the two units is disconnected, unit 1 thinks its active also and can ping the mgmt box on both internal and external networks but still cannot talk to unit 2. Once the DB-9 is restored, unit 1 can again only talk to the laptop.
Also in the dynamic arp of unit 2, unit 1's peer interface show's up as: 10.1.1.4 ff:ff:ff:ff:ff:ff peer 0 RESOLVED
And because of the lack of connectivity I cannot ConfigSync unit 2 to the new unit 1
I'm overlooking something and I would appreciated any pointers and places to look to correct this
