6.4.2 Adding Disk and Tape Drives
When you add new tape or disk drives to your system, you must physically
connect the devices and then make the devices known to the system. There
are two methods, one for static drivers and another for loadable drivers.
_______________________ Note _______________________
You will need the documentation that came with your system’s
hardware. This includes such documentation as the owner’s
guide, the disk drive guide, and the options guide.
To add a device for a loadable driver, see Writing Device Drivers: Tutorial.
To add a device for a static driver, see Section 5.4.1.
Next, you make the device special files for the device, by following these
steps:
1. Change to the /dev directory.
2. Create the device special files by using the MAKEDEV command. If you
are configuring a RAID controller, follow the procedure described in
the SCSI
(8) reference page. Use the following syntax to invoke the
MAKEDEV command:
./MAKEDEV
device#
The device variable is the device mnemonic for the drive you are
adding. Appendix A lists the device mnemonics for all supported disk
and tape drives. The number sign (#) is the number of the device, 0
through 127 for SCSI disk and tape devices. For example, to create the
device special files for two SCSI disk drives, enter the following
command:
# ./MAKEDEV rz5 rz7
MAKEDEV: special file(s) for rz5:
rz5a rrz5a rz5b rrz5b rz5c rrz5c rz5d rrz5d rz5e rrz5e rz5f
rrz5f rz5g rrz5g rz5h rrz5h
MAKEDEV: special file(s) for rz7:
rz7a rrz7a rz7b rrz7b rz7c rrz7c rz7d rrz7d rz7e rrz7e rz7f
rrz7f rz7g rrz7g rz7h rrz7h
3. Stop system activity by using the shutdown command and then turn
off the processor. Refer to Chapter 3 for more information.
4. Power up the machine. To ensure that all the devices are seen by the
system, power up the peripherals before powering up the system box.
5. Boot the system with the new kernel. Refer to Chapter 3 for
information on booting your processor.
