System action
The HyperSwap Services
request processing continues. One or more Parallel Access Volume alias
devices might not have been bound to their base volume.
Operator response
See System Programmer response. Allow WLM
to select the alias volumes for work or manually vary the base device
online unconditionally.
System programmer response
Determine why the HyperSwap Services I/O request to the new
primary volume failed and correct the problem.
Note: For IOSCOD
x'53' the I/O time out might be due to a device reserve moved to the
new primary volume and not yet released by the application. If you
are not able to resolve the problem, contact the IBM® Support Center.
