I have a Power720 system with 2 active processors, 96GB of RAM and an 8TB iASP - 50% utilized. Not a large system by today's standards.
For some reason, that is still being determined, this system CRASHED HARD (immediately did a MSD and IPL'ed) right at the beginning of a work day.
After a hard crash like this it is strongly recommended that a RCLSTG process be run.
After negotiating a 12 hour window on Sunday, I started running RCLSTG against the 8TB iASP...
After over 9 hours, the "Reading objects from disk" step was only 51% complete with an estimated remaining time of almost 9 more hours!

I had to abort the Reclaim Storage process and bring up the system, knowing full well that when (or if) I restart RCLSTG it will start from the beginning again.
It seems like the RCLSTG process needs to be modified in some way that it can complete in a reasonable amount of time. Maybe it could be designed to multitask (??) or keep track of what it had done so if restarted it could continue where it left off (??) ... All I know is it isn't working for me...
Has anyone else experienced this?
