3 - Installing the RocketRAID 3522 driver for an Exist-
ing System
Note: If a SCSI adapter is used to boot the system, make sure the RocketRAID host
adapter 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 /media/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‘/i686/hptiop.ko).
After extracting the driver module, load it using the following commands:
# modprobe sd_mod
# insmod hptiop.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”.
To create a partition on this array (which will listed as /dev/sda1), use the “fdisk /
dev/sda” command.
Next, use the “mkfs /dev/sda1” command to setup a file system on this partition.
Step 3 Configure System to Automatically Load the Driver
To avoid typing in “insmod hptiop.ko” each time the operating system is booted,
the system must be instructed to automatically load the module during bootup. To
install the module, type in the following commands (first change to the directory
where the proper hptiop.ko file is located):
#cp hptiop.ko /lib/modules/‘uname –r‘/kernel/drivers/scsi.
#depmod
