Chapter 4. Driver Installation Determining the Current Version of your 3ware Driver If you already have a 3ware controller installed, you can check the current driver version, using either 3DM 2 or the CLI. (For details, see "Viewing Information About Individual Controllers" on page 115.) You can also check it using the following method: If you have a 2.4 kernel or earlier, type the following command: cat /proc/scsi/3w-9xxx/* where the asterisk (*) represents SCSI host ID and 9xxx represents the family of the controller. For example: cat /proc/scsi/3w-9xxx/0 If you have a 2.6 kernel with sysfs, type the following command: cat /sys/class/scsi_host//stats where 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 (dmesg can also be used with earlier kernel versions.) Driver Installation Under Red Hat Linux or Fedora Core 4 Materials required • 3ware software CD-ROM • Floppy diskette, if you need to create a driver install diskette. • Red Hat Linux installation CD-ROM. (Not required if Red Hat Linux is already installed on another drive.) Creating a Red Hat Linux Driver Diskette If you are installing Linux on the new drive or unit managed by the 3ware RAID controller, you must create a 3ware driver install diskette. If Linux is already installed on another device, you may install the 3ware kernel driver module from the 3ware software CD-ROM. 40 3ware Serial ATA RAID Controller User Guide
