Adding a Disk on an Integral SCSI Controller

1. Complete the steps in the section "Adding a New Option Disk" above.

2. Use the Add_disk command to perform the remaining steps to configure the disk:

   # Add_disk controller_number drive_address lun_number

   If you are adding a second disk on controller 0 to your system, you do not have to specify the disk, controller number, or logical unit number; adding disk 2 on controller 0 is the default. If you are adding a third (or greater) disk, or if you are adding a disk on a controller other than controller 0, you must specify the disk and controller. If the disk device has a logical unit number different from zero, it must be specified.

   Add_disk checks for valid filesystems on the disk, and if any filesystems are present, you are warned and asked for permission before the existing filesystems are destroyed and a new filesystem is made.

   The Add_disk command performs these tasks:

   • Creates the character and raw device files for the new disk

   • Creates a filesystem on the disk

   • Creates the mount directory

   • Mounts the filesystem

   • Adds the mount order to the /etc/fstab file
