Subject:   Dell PowerEdge 1950: MPT0 doesn't recogniz hard drive > 2TB
Message-ID:  <>

Next in thread | Raw E-Mail | Index | Archive | Help
On a Dell PowerEdge 1950, BIOS from 2007, a freshly installed  WD 3 TB 
SATA 6GB harddrive doesn't get recognized as 3 TB disk, it is reported 
as 2TB disk only.

The box is running FreeBSD 8.2-STABLE (see below the dmesg excerpt). The 
drive is configured as ZFS pool on top of a GPT partition.

I tried the 3 TB harddrive on a FreeBSD 9.0-CURRENT box with Intel 
ICH10R SATA chipset and it worked fine, was reported as 2.7TB drive as 

I found some postings concerning mptutil not dealing with HD > 2TB, but 
this issue seems not to be a tool-issue.

a) Is this an issue of FreeBSD 8.2-STABLE or is it a firmware/BIOS issue 
which can be solved?

b) regarding to a), how can I update the BIOS/MPT firmware of the Dell 
PowerEdge 1950? Is there an option to do this via USB? As I said, the 
firmware is quite old, it's from 2007.

Thanks in advance,
