Thanks so much for all the info and the advice - right now, I am using Solaris 10u10 as a baseline version until I can figure things out. I'll try triblix as well as Debian for ldoms once I get more hard drives.

Thanks for the link and the detailed info - unfortunately the non-oracle links no longer work, and the Oracle links require a contract. Time to phone my non-existent friend, I think 

Note: As a mark of gratitude for all the help and advice I got from this community, I'd like to share one thing if it helps:  I found out is that SAS drives ordered on Ebay do not come in the Sun Marlin caddy (At least my first order did not). I had to design and print my own Marlin compatible caddy. If  anyone is interested, I can share the STL - should save you ~$12 per caddy if you are ordering them separately.

Best regards!

The link provided by johnnym shows that your ILOM software 2.0.4.20.c version corresponds to system firmware 7.1.0.g.  (Don't you just love the consistency in the numbering scheme!)

The release notes for Solaris 11.3 (https://docs.oracle.com/cd/E23824_01/htm...hardw.html) mention needing firmware 7.4.0.b or higher, from Sun/Oracle patch 147307-01.  Searching the Internet for that patch number suggests that the latest firmware revision is actually 7.4.11 in patch 147307-15 (https://www.oracle.com/servers/technolog...html#T5220).

Unfortunately access to the firmware patch requires a support contract.

Thanks so much - the elusive Solaris 11.3 stays *just* beyond my reach - at least for now : I do not have an Oracle support contract  .
