I was recently tasked with monitoring the RAID status on our Dell 1950s. This turned out to be rather irksome. I’ll skip the headache and provide the solution I found.
The following was tested on a Dell 1950 running CentOS release 5.3 64-bit
First I found that this controller was made LSI logic :
lspci -v| grep SCSI
01:00.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08)
