I've been given a CISCO ucs server to use (for a job a raspberry pie could do) with a LSI MegaRaid card in it (4 sas drives) and I'm having no luck at all getting Linux to boot off the RAID thing. It can find no boot sector on the raid devices, just loops through the nics looking for a pxi raid.
I can install happily (both Ubuntu and CentOS) but nothing will boot. The BIOS sees the virtual drive (tried raid 1 and raid 5 on the card).
The server has an SSD slot and an internal USB connector, both of which are enabled in the bios, but neither are seen by the installer (nor the bios by the looks of things). The internal USB connector seems to corrupt the data. I get no post and crazy stuff on the monitor when I plug anything in there. I have now managed to get it to boot by putting the usb drive in the rear usb connector, installing /boot on it and setting it as the boot device. Not ideal, but guess it will have to work.
Any one managed to get one of these machines to work with Linux?
There are Linux installation guides. You don't say if it B-Series or C-Series; my guess is C-Series: http://www.cisco.com/c/en/us/td/docs/unified_computing/ucs/os-install-guides/linux/b_C-Series_Linux_Install.html
Hope this helps.
