ACTION PLAN (What, Why)
-------------------------------------------------------
Hi Sysadmin,

Please check the ILOM config:-

-> ls

/SP/services/kvms/host_storage_device
Targets:
remote

Properties:
mode = miniroot
status = operational

Commands:
cd
show

-> help mode
Properties:
mode : KVMS host storage mode
mode : Possible values = miniroot,remote,disabled
mode : User role required for set = a

If the mode is set to miniroot, then change it to "disabled".

-> set mode=disabled

After that, need to do reset-all in OBP. Then connect local iso image in KVMS storage of remote console, and do reset-all again before trying to boot rcdrom.

"reset-all" seems to be redundant but it is possible to run into various errors without doing it when using rcdrom.

Kind regards,
Oracle Support
