Figure 6-4 D M=CPU command output
The output from the D IOS,CONFIG(HSA) and D IOS,CONFIG(ALL) commands no longer
has references to SHARED and UNSHARED control units. Previously, this command would
have been used to determine the HSA space available for dynamically adding control units
and I/O devices. On the z990 processor, the number of additional devices that can be added
dynamically is determined by the MAXDEV value associated with each LCSS. This parameter
is specified via HCD and is set in the IOCDS. The new output from the D IOS command is
shown in Figure 6-5.

The IEE174I, IOS050I, and IOS051I messages display not only the CHPID number, but also
the associated PCHID. This addition assists IBM service representatives and operations staff
with the diagnosis of hardware problems. The new output is shown in Figure 6-6 on page 144.
