Installing SCO OpenServer 8.2 8.2.1 8.2.2 8.2.3 Instructions on mkdev (ADM) for 3.2v5.x (Open Server) When the program mkdev hd (ADM) is started, you will be asked for the coordinates of the device you wish to install. The driver does not automatically display all devices connected, so after the installation you will find a tool named SRCSCAN in the directory /etc to display all devices. The scanning can take up to several seconds, especially when there is more than one controller in the system. The devices are displayed together with their host adapter number, target ID and LUN. These values are used in mkdev (ADM). How the HA-no., target ID and LUN are determined are discussed in Section 8.2.1 through Section 8.2.3. Note that the UNIX driver always maps the first detected host drive with target ID 0, LUN 0. This drive is used as a boot drive when the ICP RAID controller is to make the boot drive available. Host adapter Number (HA) The host adapter number assigned to the ICP RAID controller is derived from the controller's PCI slot number. Therefore, if there is only one ICP RAID controller installed in the PCI bus computer system, the host adapter number is 0. If there are two ICP RAID controllers installed, the ICP RAID controller with the lower PCI slot number is assigned host adapter number 0 and the ICP RAID controller with the higher PCI slot number is assigned host adapter 1. (Note: After a cold boot, the ICP RAID BIOS displays a couple of messages, each beginning with the controller's PCI slot number, for example, "[PCI 0/3] 4 MB RAM detected". The number after the '/' is the slot number of the controller. This will help determine the order of the ICP RAID controllers and which host adapter number is assigned to them by UNIX. See the Hardware Guide for more details. UNIX Target ID and LUN Target IDs and LUNs for Non-Direct Access Devices (devices like streamers, tapes and CD-ROMs and, therefore, not configurable via ICPCON), are directly assigned to the SCSI ID and the channel of the ICP RAID controller. Host drives are assigned in increasing order to the free coordinates (bus number and target ID, LUN is always 0). Configuration Example In this example, the PCI computer has two ICP RAID controllers (HA 0 = 1st ICP RAID controller, HA 1 = 2nd ICP RAID controller), each with two SCSI channels. See the information below. The resulting HA, Bus, Target ID and LUN are indicated in Table 8-6. 1 Hard Disk as host drive no. 0 on HA0 1 Hard Disk as host drive no. 0 on HA1 1 Hard Disk as host drive no. 1 on HA1 1 Hard Disk as host drive no. 2 on HA1 1 Streamer SCSI ID 2, LUN 0 on SCSI Channel A of HA0 1 CD-ROM SCSI ID 3, LUN 0 on SCSI Channel B of HA0 1 DAT SCSI ID 2, LUN 0 on SCSI Channel A of HA1 Software Installation and User's Guide 85
