HyperPAV operations z/OS MVS Setting Up a Sysplex SA23-1399-00 |
|
Use the following commands for HyperPav operations in your sysplex:
For example, Figure 1 shows the information that can
be returned by the D M=DEV command.
Figure 1. Example: Results from D
M=DEV command
You can determine the current HYPERPAV setting on the system using
the D IOS,HYPERPAV command. Figure 2 shows
an example of the command results.

command
Note that the presence of non-FICON channels to a HyperPAV-capable
control unit will cause the system to operate on base devices in
that logical subsystem (LSS) in base only mode. In base only mode,
it is not possible for the system to use alias devices for bases in
the logical control unit. You might receive message IOS166E indicating
that the HYPERPAV LSS for a device is now in base only mode. You can
also detect the condition using the D M=DEV(bbbb) command
where bbbb is a base device in the logical control unit.
Once this condition is resolved by removing or configuring offline
the non-FICON channels from the HyperPAV configuration, HyperPAV aliases
might be usable. However, might have to force the system to rediscover
aliases that were not previously discovered using the VARY command,
where bbbb is an online base device in the logical control
unit:
