The format utility automatically configures SCSI disk drives even if that specific type of drive is not listed in the /etc/format.dat file. This feature enables you to format, create slices for, and label any disk driver that is compliant with the SCSI-2 specification for disk device mode sense pages.
Here are other options for adding disks:
If you are adding a SCSI disk, you might to try the format utility's automatic configuration feature.
You might try hot-plugging a PCI, SCSI, or USB disk. For more information, see Chapter 5, Managing Devices (Overview/Tasks).
The following steps are involved in configuring a SCSI drive by using automatic configuration:
Shutting down the system
Attaching the SCSI disk drive to the system
Turning on the disk drive
Performing a reconfiguration boot
Using the format utility to automatically configure the SCSI disk drive
After the reconfiguration boot, invoke the format utility. The format utility will attempt to configure the disk and, if successful, alert the user that the disk was configured. For step-by-step instructions on automatically configuring a SCSI disk drive, see How to Automatically Configure a SCSI Drive.
Here's an example of a partition table for a 1.3-GB SCSI disk drive that was displayed by the format utility.
Part Tag Flag Cylinders Size Blocks 0 root wm 0 - 96 64.41MB (97/0/0) 1 swap wu 97 - 289 128.16MB (193/0/0) 2 backup wu 0 - 1964 1.27GB (1965/0/0) 6 usr wm 290 - 1964 1.09GB (1675/0/0)
# touch /reconfigure
# shutdown -i0 -gn -y
Brings the system down to init level 0, the power-down state.
Notifies logged-in users that they have n seconds before the system begins to shut down.
Specifies that the command should run without user intervention.
The ok prompt is displayed after the system is shut down.
Typically, a small switch is located at the back of the disk for this purpose.
Refer to the disk's hardware installation guide for details.
The system boots and displays the login prompt.
