Re: pwrdwnsys restart-yes did not restart

Does PWRDWNSYS RESTART(*YES) actually power down the drives? I was under the impression it was a software power-down only; the hardware may be issued a 'reset' command, but that's about it.

With 'modern' equipment one of the IPL options (the current default?) is to not perform any hardware diagnostics and just reboot the software (unless the system detects hardware changes).

IBM CE told me one of the drives took "too long" to spin up so the IPL
was aborted by the service processor. The 9332 DASD had gotten close
to the MTBF. What I recall was the bearings were beginning to fail.
I don't recall the timing, but somewhere in that period, the CE called
stating he needed to replace the load source and would be onsite in an
hour.
