Finding out what the hard drive model and capacity.

[Paul Ambrosio]

We are looking for some Linux command or file that would indicate us what model and size of hard drive is installed in our machines. Some commands like dmesg | grep hd don't seem to work on the HP DL-360's because of the way the driver is installed in those models.

The Gnome GUI, System Tools > Hardware Browser seems to show the drvies make and size on my system.

Tried that, works on my desktop but I can't get it to work remotely, querying the servers. Any idea of a line command?

model can be found in /proc/scsi/scsi

You have one of these.

72.8-GB 10,000 rpm U320 Universal Hard Drive (1") 286714-B22

Hi Paul,

in /proc there ara a lot of information about everithing.

For example:

cat /proc/ide/ide0/hda/capacity
cat /proc/ide/ide0/hda/model

the capacity is en 512 byte blocks so you must divide it by 2. You can try:

echo "`cat /proc/ide/ide0/hda/capacity`/2" | bc

Frank, that unfortunately that won't work here, as the HDD's would be connected to a SCSI bus in the DL360 series.

If the drives are attached to a standard SCSI bus (i.e. not a RAID controller), then '/proc/scsi/scsi' might have the details you are after.

If not, then you'll need the ACU-XE installed in order to access that level of device information (from the RAID controller directly). You are using a SmartArray aren't you?

Thanks folks,

Stuart's answer solved the puzzle. For some reason the /proc/scsi/scsi on the DL-360 doesn't have the information. As I mentioned before, someone from redhat told me those boxes have an odd drive configuration. Even a third party software like "lshw" fails to display the drive. ACU-XE seems to be the answer.

Paul,
in that case the physical disk are 'shielded' by the SmartArray controller. What you see as 'SCSI disks' are really logical disks from the controller presented through a SCSI emulation layer.

if you have cciss
