unexpectedly

Apologies for being late and/or not quite on topic, I have a 3008 series raid controller I got new for $200. I talk about it on my other post in this forum.

FWIW, I bought a 3008 card (thankfully for only $200) before I read up enough on ZFS and wanting access to each disk. I did get it reflashed to IT mode and the 6 drives I have show up individually in debian. I got the firmware here from Supermicro's ftp site. Note that the first visit to the ftp site requires you to acknowledge / agree it's not their fault. Then you need to go back and hit the link again. It also may or may not popout. Then I put the UEFI IT files on the same LMDE usb boot stick I used for installing the OS and booted to the UEFI: shell via bios boot menu. Didn't know that you need to use dos-like command to switch to the usb drive. btw, shift pg-up works for scrollback. The uefi script failed to flash, so I went back later and executed the same commands from the script one at a time and it flashed ok. Also, since this is similar to the LSI 9300-8i, I went there and downloaded all the files. sas3ircu worked out of box in debian; I made that one file executable & copied to /usr/sbin Of note, the 9311-8i OEM version has better user documentation. Could anyone point me to a way to configure the write caching? I'm still trying to figure that out. Hardware is a new Lenovo ThinkServer RD430 that I basically stole off Amazon for $699. Edited to add: I just confirmed this is offered by Intel, too as the RS3UC080 and their product page specifically mentions RAID and JBOD in the same breath. This is intel's ark page for the rs3uc080. This is the software download page and I'm thinking I may try flashing to intel's firmware.
