The packages comes with a python wrapper around megasasctl and an initscript that periodic run this wrapper to check status. And SuperMicro support helped us: Now we’re going to enable write cache. However it’s really hard to use because it’s use tones of command line parameters and there’s no documentation. I’m going to wait for a response from Supermicro I’ve emailed them before I flash my SAS controller with the firmware suggested above. Mind you, I now know more about my RAID controller than I would have had it not been so broken, so it’s not a complete loss! The first one with a RAID1 array working fine.

It’s quite new and thus, may be missing in some not-up-to-date distributions.
After that, you’ll be able to boot rddhat SAS. Totally fed up with all these issues I decided to put in a decent RAID controller with proper linux support, a store nearby had an Adaptec on stock.
It will log a ligne to syslog when something failed and will send you a mail. After that you can flash BIOS.
Mind you, I now know more about my RAID controller than I would have had it not been so broken, so it’s not a complete loss! The utility hides them so that you cannot include the same disk twice in a volume.
When you are satisfied with your choices, type c to create the array. The controller will now recognise the disk as being a “foreign” one.
LSI MegaRAID SAS
All theses card can be used with stock Linux kernel which includes a working driver. The BIOS screen appears. Power off your server module and then power it back on.
How should we search the sas adress.

However, Rdhat already did this for you. When the utility finishes creating the volume, the main screen reappears. My previous server had normal SATA disks li was installed with no difficulty at all. It shows me a list of possible drivers, but neither mpt e. I would have expected a better explanation about this disk-giving jumper. I am trying to install a new server with Ubuntu 8. That is, you cannot mirror a disk with itself.
The first one is already setup but we have just plugged a disk bays on the second card. Hope someone else can benefit. Assuming your new unassigned drive is identified as!
U’re not able to boot from SAS disks. And SuperMicro support helped us: This issue was NOT resolved, see the third post below.
In my case this firmware help: However, please that most of old distributions won’t have this driver. It’s lsl standard nagios expected return code. In total I tried about a dozen different ones that could be related to my controller to no avail.
The next screen lists the disks you can choose to include in the volume and also disks you can choose as hot-spares. In this mode, Ubuntu detects the drives just fine and allows me to setup soft raid in linux.

11068e Write cache should be enabled ONLY if you have a battery pack on your controller. When the next screen appears, select View Existing Array and press Enter.
You can write your own script around megasasctl to check your adapter status health periodically. Thanks in advance for any help.
