Hi,

I would like to know the procedure to bring HMC and VIO(dual) server behind the firewall. Right now both of them are infront firewall and customer want to bring it in behind firewall.We have to change the IP & VLAN for VIOS also. Is there any way to proceed this request without downtime and can anyone share some idea about this request.Thanks.
Regards,
aby

hi abyalex,

you are dealing with two distinct matters.

1. HMC behind firewall

from HMC <-> frame connections, it is irrelevant, once you make sure that they keep communicating at the same network segment (or, in other words, at the same firewall side).

regarding to external connections (like admin team using HMC), you must ensure some ports are opened. Further details on that can be found on this DeveloperWorks article: https://www.ibm.com/developerworks/wikis/display/virtualization/HMC+and+system+setup

2. VIO behind firewall

for instance, a VIO server behind a firewall works exactly as a common server behind the firewall. An outage, from customer perspective, will only happen if you move cables from adapters being used on SEA from both VIO Servers at same time. Otherwise, no outage is expected.

I hope it helps.

Best regards,
Luciano Martins.
