If you have i5/OS, you can download server firmware fixes and operating
system PTFs at the same time. If you have an HMC, you can either get the server
firmware fixes through the HMC, or get the server firmware and
PTFs through i5/OS at
the same time (except for the model
575 or 59x server). However, if there is a concurrent
server firmware update available through the
HMC,
you might choose to use the
HMC.
Note: Installing
the server firmware fixes through the operating system is a disruptive (nonconcurrent)
process.
