We're doing our quarterly downtimes this week. The first one is our P8. Five lpars of IBM i, of which one hosts disk for the others. Two lpars of VIOS.
The saves are done on the four guests. Three of the four guests are down. The fourth one is still at D6000298, which it has been before I began my 45 minute commute into work. This guest comes off of the slow 10K spinning disk ASP on the host.

Gee a power down right after a full system save, on slow disks. Sure sounds like:

IBM i 7.4
System in restricted state (Normally a good place to be before you issue the PWRDWNSYS). What options do you use on CLRPOOL? This lpar is not running a "traditional" load of batch and interactive. If there were ever two interactive users at once that would be a large number. Three might be a record. Mostly Domino work. One Domino server. Therefore no QINTER, QBATCH but instead it uses QBASE.

When it is possible to control the power down sequence, I am often used to end the applications, initiate several times a CHGASPACT *FRCWRT to force memory to be dumped to disk, go to restricted state in a controlled way, continue CHGASPACT until the system is in restricted state..

Then I initiate the PWRDWNSYS with a short delay only when there is no more disk activity as WRKSYSACT shows.

I had this long D6000298 issue in the past and I always feel uncomfortable until it completes after several tens of minutes. Not sure if it solves all the causes, because I do not really know them, but I never got them again.
