Indeed. A reboot later, everything was a mess. I rebuilt the RAID and
repeated the install.
Found that Disk Druid correctly sees the only device (referred to as
/mapper/isw_[10 seemingly hex digits]_Volume0, everything goes completely as
However, at the next boot the installed kernel no longer believes there's a
single device there, and goes like this:
No RAID sets and with names 'isw_[same digits]_Volume0'
failed to stat() /dev/mapper/isw_[same digits]_Volume0
My fault was not installing the proper Intel RAID driver for RHEL... the
regular kernel does not provide it.
Thanks very much for your help
