Determining the Current Version of Your
3ware Driver
You can view controller and driver information in several different ways:
„
Using 3DM 2 (see the “Controller Summary Page” on page 45)
„
Using 3BM (see “Displaying Advanced Details” on page 25)
Under Linux, you can also type the following command if you have a 2.4
kernel or earlier:
cat /proc/scsi/3w-9xxx/0*
where the asterisk (*) represents controller number and “9xxx” represents the
version of the controller. For example:
cat /proc/scsi/3w-9xxx/0
If you have a 2.6 kernels with sysfs, type the following command:
cat /sys/class/scsi_host/<hostid>/stats
where <hostid> is usually host0, unless other SCSI devices are available, in
which case it may be host1 or higher.
If you have a 2.6 kernel without sysfs, type the following command:
dmesg | grep 3w
