Learn Cycle:
This can take up to 12 hours to complete.
The calibration (Autolearn mode) is a process whereby the controller records the battery discharge curve in order to know the battery autonomy, in addition to maximum and minimum voltages. It is split into three (3) steps:
Step 1: Begin calibration. The controller charges the BBU to maximum capacity.
Step 2: The controller discharges the BBU.
Step 3: The controller recharges the BBU. When maximum capacity is reached, the process is finished.
Note: If either Step 2 or Step 3 is interrupted, the learning process stops and will not restart.
It is not recommended to disable the "Learn Cycle" of the BBU as it will shorten the service life of the battery to one-third (approximately eight (8) months) of its original useful life of two (2) years.
In my case the M5014 is controller 0 (the only one) in the system.
You can speed up the initialisation in 3 simple steps:
MegaOEM -AdpSettings Write -f MyM5014.ini -a0
...reads MFC_DEFAULT structure and creates an INI file. Inside the INI search for "delayPOST" and change the value. Possible coded values: 0 to 7, which gives a value of 0, 15, 30, 45, 60, 75, 90, 105 seconds.
MegaOEM -AdpSettings Read -f MyM5014.ini -a0
...reads INI file, forms MFC_DEFAULT structure and sends it to the FW.

отличный ответ от lsi:
My apologies for the wrong information provided in my previous email.
I was under the impression that this OS is still supported but after
checking with our developer, FreeBSD is currently not supported with
the LSI Megaraid Cards due to some issue with the driver we've
provided. It will be supported in our upcoming releases which may come
by the end of this year. Please check back on our website during that
time frame for the FreeBSD driver.
Чтобы прошить прошивку, нужно стереть прошивку — но главное !!! НЕ ПЕРЕЗАГРУЖАТЬСЯ OMG
Flashing IT firmware over IR firmware (and vice versa) for SAS HBAs kb.lsi.com
Тут у коллег с 3-го этажа вчера сдохли кондиционеры, и перегрелся один из серверов. На нём перестал собираться raid5 на контроллере MegaRAID SAS 1078 — два диска выпало из массива и у обоих статус "unconf bad". Посмотрели стату дисков, ошибок нету. Ну и пометили оба "unconf good", после чего контроллер предложил сделать import, ну и в общем потом массив собрался.
