TX2550 M4 Drives not detected

[Thomsonibus]

Hello all,
I've recently bought a tx2550 m4 (T2554SC020IN) and 4 sas hdd (S26361-F5550-L130)
When i boot the server and going in bios setup, the embedded lsi software raid controller does'nt see any drive. Also the drive have no ligths (just a brief blink at startup)
Is there a compatibility issue between this server and this kind of drives ?
Anyone have an idea ?
Thanks in advance for your expertise.

Isn't the onboard/embedded controller SATA-capable only?
Did you configure an additional SAS RAID controller during order, and will find the disks on that controller's configuration utility?
While SAS controllers mostly can drive SATA devices, SATA controllers can't drive SAS devices.

Did you try firing up the system booting the ServerView Installation Manager DVD, and checked its hardware inventory report?

Thanks me@work . Indeed the onboard controller just drive sata drives... I'll order an extra one.
There was an error in the description of the vendor
