HMC System Support

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

2.10.1can 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/ omb/memoranda/fy2005/m05-22.pdf and http: //www.whitehouse.gov/omb/egov/documents/IPv6_ FAQs.pdf

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
