Re: Allocating controller via HMC programmatically

Mark,
Yes, you can. You will need a free software named "LPAR TOOLKIT" from IBM.

Best Regards.

  I have just started a project at a client and my colleague has run
into a situation brought on by the installation of the HMC.

  OS version: v5r3.
  HMC version: 5.1

  The goal is to be able to allocate (switch over) the I/O controller
for the tape drive programmatically between LPARs.  Previously
(before the HMC was installed) he was using the QYHCHCOP (Perform
Hardware Configuration Operations) API to accomplish the
switch.  Since we don't know when the first partition's backup will
end, we can't just schedule the switch at a fixed time via the
HMC.  Therefore, we'd like to make the allocation
programmatically.  Is this possible?  Can anyone supply some sample code?
TIA.
