For crashes, I think most of the HA vendors would say they can do it. For IBM's solutions, I know of the below but most of our customers are hesitant to let the system bring up a target without determining the cause of the failure. I think that will change as more and more go to a SAN/hardware solution.
HMC Remote Restart (can be integrated with a monitoring solution)
PowerHA (heartbeat capability, via IP or HMC)

Subject: RE: PowerHA for IBMi
But if you need an OS upgrade/PTFs etc, the OS must be restarted.
For those outages, you can use PowerHA to reduce the downtime (my
customer experiences is 15-20 minutes for a switch) but it won't zero
the outage needed to move the disk assignment.
Patrick, That's what I thought... That is better than a couple of hours though !
For failures, PowerHA and/or HMC Remote restart can be used to automate
recovery for less hands on.
So, is there ANY solution on the market that can perform a HOT SWAP of IBMi in the event of a crash?
