You will get an .scexe file, which you can unpack: $ chmod 740 CP022551.scexe $ ./CP022551.scexe –unpack=/tmp/iLO3 $ ls -l /tmp/iLO3 CP022551.xml flash_ilo3 ilo3_180.bin README.TXT There you have it: a ilo3_180.bin which you can upload with your iLO 3 web interface.
Some controllers allow to flash drive firmware with built-in utilities (adaptec does for sure), but anyway – it’s not safe, especially for arrays. Even utilities can do that – I won’t. It’s better to update drives one-by-one and rebuild them. There is a risk that drives might not work after firmware flash and in case … Read more
