Thanks @phillxnet -
Understand and appreciate that… with the FC HBA booted but with no drives, I’m still not seeing anything sensible coming up - when two SAS (or SATA) drives attached, the installer just bombs completely and I’m unable to access the anaconda environment (as I get the error on a black GUI screen and can’t switch to tty2)
With only one SATA or SAS drive attached directly, it seems to be presented as read only according to the logs.
I’ll re-run that test with a fresh pair of eyes and ensure it’s repeatable and not just a spurious error.
I was just a bit surprised that all my multipath devices were detected and not a bog-standard SAS array
