Installing SCSI Devices
Probably the most important point to keep in mind when adding scsi disk drives to your system is with regards to scsi target conflicts. A scsi target is simply an address assigned to the scsi disk or device which must be unique from all other scsi devices on the same scsi controller. With standard 8-bit narrow scsi controllers, you may have seven devices number from targets 0-6, attached to the controller. With the addition of a second controller, you may add an additional seven devices to further expand your storage capacity. Having duplicate scsi targets on a system during boot can cause file system damage to your system and render it useless. This is a severe case and usually the worst thing that happens is the system does not boot until the conflict is resolved. To circumvent this problem do the following:

1. Attach any new scsi devices and choose, to your best knowledge, a unique scsi target address.
   
2. Turn on the devices and then the cpu
   
3. Just after the initial Sun banner is displayed, hit the <stop>-a key combination to stop the boot process.
   
4. At the OK prompt enter, probe-scsi-all and hit return. This will display any and all devices that are attached to the system and that are turned on. Check to make sure you have a proper count for all devices attached and that there are no scsi target conflicts.
   
5. Finally, at the OK prompt enter boot -r to continue the boot process and reconfigure the kernel to support any new scsi devices added or inform the kernel of any devices removed. Basically what happens during this boot step is that the system configures and devices entries and links required for the system to access the new scsi devices.

After following the previous steps you should have an up and running system with no conflicts and properly built devices for any new scsi targets added. Next you must prepare the disk for use as a mounted file system for access by the system and users.

Preparing Your Disk Drive
Unlike the CDrom, there is more to preparing your disk drive to be used by the users. After completing the above steps, the CDrom drive is ready to use. Simply insert your CD disk and up will pop a file manager window with the contents of the CD. On the other hand, to mount and access your disk drive you must partition it and create file systems from which to mount to a local directory for transparent user access. Follow the instructions below to partition and create file systems on your new hard disk:

1. Run the format utility and choose the new disk from list of available disk drives.
   
2. Select partition and print from the sub-menus that follow.
   
3. Begin partitioning your disk according to the steps outlined in my (Partitioning Other Disks section of the Installation Tips Guide).
   
4. Type label to commit your changes to the disk and then exit the format utility.
   
5. Create a file system on the new partition or partitions:

# newfs /dev/rdsk/c0t0d0s2

The above example will create a unix file system on slice 2 of the scsi disk at target 0 on the systems internal scsi controller.

6. Create a directory for use as a mount point for the new file system.
   
7. Mount the new partitions to the created mount points. Example, # mount -F ufs /dev/dsk/c0t0d0s2 /mount_point
   
8. Add entry to the /etc/vfstab file so that this new file system is accessible each time the system boots.

Modem Installation
Installing a modem is very straight forward. First, attach your modem to either serial port a or b on the back of the system. Second, start the admintool program as superuser or, if you are part of the sysadm group, you would have the permission necessary to run admintool. Select the serial port configuration button. Next, select the serial port that you attached the modem to and select modify from the edit menu. Finally, choose the appropriate template from the template menu for how you intend to use the modem and adjust the baud rate to, if nothing prohibits you from doing so, 38400 baud. Click OK or Apply and your done; the modem can now be accessed and dial out or be set to auto-answer for incoming calls.
