What I can't find out though is, can IBMi IPL off a HPE 3PAR SAN?

While I can't answer this one, allow me to ask why you would IPL from SAN? My opinion is, servers have an (often) specific OS and configuration settings as well as licenses are sometimes tied to the hardware. From this PoV, it doesn't make sense to boot everything from SAN. I'd keep the OS on a local disk mirror and have data on the SAN, on ASP > 1.

Besides that, I also don't know about disk blocksize issues. IBM used disks with 522 Bytes per sector for metadata housekeeping, extra vendor-specific SCSI commands and other IBM glitter spray to bless disks. This is also true for not so old hardware like an 8203 (without VIOS). Dunno if these requirements also exist with SAN based storage.

Maybe check with HPE?

:wq! PoC
