Check Text (C-215411r991589_chk)
Check the servers boot lists for the "normal", "service", "both", or "prevboot" modes by command:
# bootlist -m <mode> -o
Ensure "hdisk{x}" is the only devices listed. If boot devices, such as "cd{x}", "fd{x}", "rmt{x}", or "ent{x}" are used, this is a finding.
Fix Text (F-16607r294685_fix)
Configure the system to use a bootloader installed on fixed media, such as:
# bootlist -m normal hdisk0
# bootlist -m service hdisk0
