IBM z13s - RSF Connections to IBM and Enhanced IBM Service Support System

404 IBM z13s Technical Guide
11.4.2 RSF connections to IBM and Enhanced IBM Service Support System
If the HMC and SE are at Driver 27, the driver uses a new remote infrastructure at IBM when
the HMC connects through RSF for certain tasks. Check your network infrastructure settings
to ensure that this new infrastructure will work.
At the time of writing, RSF still uses the “traditional” RETAIN connection. You must add
access to the new Enhanced IBM Service Support System to your current RSF infrastructure
(proxy, firewall, and so on).
To have the best availability and redundancy and to be prepared for the future, the HMC must
have access to the Internet to IBM through RSF in the following manner. Transmission to the
enhanced IBM Support System requires a domain name server (DNS). The DNS must be
configured on the HMC if you are not using a proxy for RSF. If you are using a proxy for RSF,
the proxy must provide the DNS.
The following host names and IP addresses are used and your network infrastructure must
allow the HMC to have access to them:
򐂰 Host names:
– www-945.ibm.com on port 443
– esupport.ibm.com on port 443
򐂰 IP addresses. IPv4, IPv6, or both can be used:
–IPv4:
• 129.42.26.224:443
• 129.42.34.224:443
• 129.42.42.224:443
• 129.42.50.224:443
• 129.42.56.189:443 (enhanced)
• 129.42.58.189:443 (enhanced)
• 129.42.60.189:443 (enhanced)
• 129.42.54.189:443 (enhanced)
–IPv6:
• 2620:0:6C0:1::1000:443
• 2630:0:6C1:1::1000:443
• 2630:0:6C2:1::1000:443
• 2620:0:6C4:1::1000:443
• 2620:0:6C4:200:129:42:54:189:443 (enhanced)
• 2620:0:6C0:200:129:42:56:189:443 (enhanced)
• 2630:0:6C1:200:129:42:58:189:443 (enhanced)
• 2630:0:6C2:200:129:42:60:189:443 (enhanced)
11.4.3 HMC and SE remote operations
These methods are available to perform remote manual operations on the HMC:
򐂰 Using a remote HMC
A remote HMC is a physical HMC that is on a different subnet from the SE. This
configuration prevents the SE from being automatically discovered with IP multicast. A
remote HMC requires TCP/IP connectivity to each SE to be managed. Therefore, any
Note: All other previous existing IP addresses are no longer supported.
