IPv6 addresses are easily identified. A fully qualified IPV6 address has 16 bytes. It is written
as eight 16-bit hexadecimal blocks that are separated by colons, as shown in the following
example:
2001:0db8:0000:0000:0202:b3ff:fe1e:8329
Because many IPv6 addresses are not fully qualified, shorthand notation can be used. In
shorthand notation, the leading zeros can be omitted, and a series of consecutive zeros can
be replaced with a double colon. The address in the previous example also can be written in
the following manner:
2001:db8::202:b3ff:fe1e:8329
For remote operations that use a web browser, if an IPv6 address is assigned to the HMC,
navigate to it by specifying that address. The address must be surrounded with square
brackets in the browser’s address field:
https://[fdab:1b89:fc07:1:201:6cff:fe72:ba7c]
Using link-local addresses must be supported by your browser.
11.4 Remote Support Facility
The HMC RSF provides important communication to a centralized IBM support network for
hardware problem reporting and service. The following types of communication are provided:
򐂰 Problem reporting and repair data
򐂰 Microcode Change Level (MCL) delivery
򐂰 Hardware inventory data, which is also known as vital product data (VPD)
򐂰 On-demand enablement
11.4.1 Security characteristics
The following security characteristics are in effect:
򐂰 RSF requests always are initiated from the HMC to IBM. An inbound connection is never
initiated from the IBM Service Support System.
򐂰
All data that is transferred between the HMC and the IBM Service Support System is
encrypted with high-grade Secure Sockets Layer (SSL)/Transport Layer Security (TLS)
encryption.
򐂰 When starting the SSL/TLS-encrypted connection, the HMC validates the trusted host
with the digital signature that is issued for the IBM Service Support System.
򐂰
Data that is sent to the IBM Service Support System consists of hardware problems and
configuration data.
For more information about the benefits of Broadband RSF and the SSL/TLS-secured
protocol, and a sample configuration for the Broadband RSF connection, see
Integrating the
HMC Broadband Remote Support Facility into Your Enterprise, SC28-6951.
Consideration: RSF through a modem
is not supported
on the z13s HMC. Broadband
connectivity is needed for hardware problem reporting and service. Modems on installed
HMC FC 0091 hardware do not work with HMC Version 2.13.1, which is required to
support the z13s server.
