Use the DISPLAY HS command to display information about the Basic HyperSwap® function and the status of device
pairs in the PPRC configuration. The issuing operator must have at
least RACF® READ authority for
the DISPLAY HS command or console INFO authority.
See Table 1 and Table 1 for additional information. The DISPLAY HS command will fail if the Basic HyperSwap Management address
space is not started.
Note: Basic HyperSwap (BHS)
command handling is performed by the BHS Subsystem Interface (SSI)
exit processing. Therefore, this command requires the BHS management
address space to be active in order to recognize and process this
command. If this command is issued when the BHS management address
space is not active, then message IEE305I will be issued indicating
that the command is not valid at this time.
D HS,{STATUS}
{CONFIG[(DETAIL[,ALL]|EXCEPTION[,ALL])][,NAME(session_name)]}
|
- STATUS
- Displays the current status of the Basic HyperSwap function
for all systems in the sysplex (for example, enabled, disabled, HyperSwap in progress).
Message IOSHM0303I
is issued in response to the D HS,STATUS command and the output is
routed to the issuing console. See
z/OS MVS System Messages, Vol 9 (IGF-IWM) for
more information about the IOSHM0303I message.
- CONFIG
- A list of configurations (session names and session types) being
maintained by Basic HyperSwap is
displayed. When CONFIG is issued with either the DETAIL or EXCEPTION
parameter, the current state of device pairs in the PPRC configuration
(for example, Duplex, PPRC suspended, No Secondary Access) is displayed. The optional NAME parameter can be specified to display
a specific configuration. If NAME is not specified, the information
for the configuration currently preferred for HyperSwap is displayed.
- DETAIL
- Lists devices with any exception in the rightmost Status column.
- EXCEPTION

When ALL is not specified (the default),
32 devices are displayed, followed by nnnn Devices
not Displayed.
- NAME(session_name)
- Specifies the name of the HyperSwap configuration
from which the device pairs are to be displayed. When NAME is not
specified, the device pairs in the current HyperSwap viable configuration are displayed.
