The following steps need to be taken to install a disk onto a server. It
assumes you are using Apple HD SC Setup or some third party formatting tool
that supports UNIX partitioning. The drive that will be used in this
example is a Micronet CPK-200, set to SCSI ID #5.
Use the formatting tool to create a "Free UNIX slice 3" on the disk, which
creates the partition we will be using. Attach the disk to the server, and
then execute this command from CommandShell:
newfs /dev/rdsk/c5d0s3 Generic
The parameter "Generic" (which is case sensitive) in the command line
specifies that there is no specific drive entry in the /etc/disktab file.
Entries are provided for some disks. If your disk is not one of them, you
can either specify "Generic" for the drive type or provide the drive
information from the manufactures documentation. This information allows
newfs to tune the disk performance somewhat, but isn't critical, so if you
don't have it handy, the Generic entry is usually close enough.
The AWS 95 supports 4 logical SCSI busses number 1-4 so that when you
connect the drive to the PDS card's external connector, the command that
you will need to enter changes to the following:
newfs /dev/rdsk/c405d0s3 Generic
Since you have not used "Apple HD SC Setup" program you will also need to
create an entry in the /etc/fstab file so that this drive can be
automatically mounted when the system is restarted. For this example we
will assume that the drive will be mounted on a directory within the
"/Shared Data" folder. Open the /etc/fstab file by traversing in the Mac
environment and double-clicking on the file. The file should look
something like the following:
/dev/dsk/c300d0s0 / ignore rw 1 0
Now append a new line to the file specify an existing directory in the /
Shared Data folder.
/dev/dsk/c205d0s3 /\\ Shared\\ Data/NewVolume 4.2 RW 1 2
In this instance the NewFolder that is used for the mount point is
NewFolder. The back slashes are necessary as the string / Shared Data has
a space in it. You can create the directory for NewVolume from the
CommandShell or from the Mac environment. Now you can close and save the
/etc/fstab file.
To make this volume accessible to users you can enter the following command
from the CommandShell:
mount -a
If there is a problem you will see some error text after this command is
executed. To verify that the drive is now accessible you can type mount
and receive output similar to the following:
/dev/dsk/c300d0s0 on / type 4.2 (rw,noquota)
/dev/dsk/c205d0s3 on / Shared Data/NewVolume type 4.2 (rw)
When adding new drives to the AWS 95 it is also important to add them to
the PDS card as this will give you maximum performance. The DMA and Cache
provided by the card will help increase I/O as compared to the motherboard
internal and external busses.
