The new functions available on the Hardware Management
Console (HMC) version 2.10.1 apply exclusively to System
z10. However, the HMC version 2.10.1 will continue to sup-
port System z9, zSeries, and S/390
®
G5/G6 servers.
The 2.10.1 HMC will continue to support up to two 10
Mbps or 100 Mbps Ethernet LANs. A Token Ring LAN is
not supported. The 2.10.1 HMC applications have been
updated to support HMC hardware without a diskette
drive. DVD-RAM, CD-ROM, and/or USB fl ash memory
drive media will be used.

Internet Protocol, Version 6 (IPv6)
HMC version 2.10.1 and Support Element (SE) version
2.10.1 can now communicate using IP Version 4 (IPv4),
IP Version 6 (IPv6), or both. It is no longer necessary to
assign a static IP address to an SE if it only needs to com-
municate with HMCs on the same subnet. An HMC and
SE can use IPv6 link-local addresses to communicate with
each other.
HMC/SE support is addressing the following requirements:
• The availability of addresses in the IPv4 address space
is becoming increasingly scarce
• The demand for IPv6 support is high in Asia/Pacifi c
countries since many companies are deploying IPv6
• The U.S. Department of Defense and other U.S. govern-
ment agencies are requiring IPv6 support for any prod-
ucts purchased after June 2008
More information on the U.S. government require-
ments can be found at: http://www.whitehouse.gov/

HMC/SE Console Messenger
On servers prior to System z9, the remote browser capa-
bility was limited to Platform Independent Remote Console
(PIRC), with a very small subset of functionality. Full func-
tionality using Desktop-On-Call (DTOC) was limited to one
user at a time and was slow, so it was rarely used.
With System z9, full functionality to multiple users was
delivered with a fast Web browser solution. You liked this,
but requested the ability to communicate to other remote
users.
There is now a new console messenger task that offers
basic messaging capabilities to allow system operators or
administrators to coordinate their activities. The new task
may be invoked directly, or using a new option in Users
and Tasks. This capability is available for HMC and SE
