Linux Driver Support

5 -

the system be to boot from the RocketRAID 1720.

Continue the installation as normal. You can refer to Red Hat Enterprise Linux installa-

tion guide.

Note:

1. The system device mapping order is the same as the order shown in RocketRAID

1720 BIOS Setting Utility. If no other SCSI adapters are installed, the device marked

as “BOOT” or “HDD0”will identified as /dev/sda, “HDD1” as /dev/sdb, “HDD2” as

/dev/sdc, etc. When creating mount points, /boot must be mounted on /dev/sda.

3 - Installing the RocketRAID 1720 driver for an Exist-

ing System

Note: If a SCSI adapter is used to boot the system, make sure the RocketRAID 1720

controller BIOS loads/posts after the SCSI adapter’s BIOS. It may be necessary to

move the adapter(s) to another PCI slot.

Step 1 Obtain the Driver Module

Extract the module file from the file modules.cgz (from the driver disk) using the

following commands:

# mount /dev/fd0

# cd /tmp

# gzip -dc /mnt/floppy/modules.cgz | cpio -idumv

Driver modules for all supported kernel versions will be extracted. The driver module

for the active kernel is located under the directory that matches the kernel version (/

tmp/‘uname –r‘/rr172x.ko).

After you have extracted the driver module, you can load it by following commands:

# modprobe sd_mod

# insmod rr172x.ko

Arrays attached to the adapter can be accessed as SCSI devices (e.g. /dev/sda).

Step 2 Mounting and Partitioning the Device

Example: A RAID array has been configured between several hard disks.

This array will be registered to the system as device “/dev/sda”.
