Take these steps to install the
Ultra2 LVD SCSI Host Adapter
driver in an existing
SCO UNIX system and make the Adapter you just installed bootable:
1. Insert Driver Disk 2 in your floppy drive.
2. Type “installpkg” at the command prompt and press <ENTER>. The system
will ask you what packages you want to install. Type: “a10<ENTER>”.
3. Edit the “mscsi” file. First type in these lines at the system prompt:
cd /etc/conf/cf.d < ENTER >
cp mscsi mscsi.bak < ENTER >
vi mscsi < ENTER >
Once you are inside vi, the editor program, you need to manually add lines to
“mscsi” that identify all of the devices attached to the Adapter. Refer to the
example below: “ha” stands for “host adapter” (for which you should enter
“a10” for each device attached to an Ultra2 LVD SCSI Host Adapter); “attach”
stands for the type of device attached (“Stp” = tape drive, “Sdsk” = hard disk
drive, “Srom” = CD-ROM drive); “number” stands for the adapter number, a.
k. a. the number that the motherboard has assigned to the PCI bus the
Adapter is on; “ID” stands for the SCSI ID number; “lun” stands for logical
unit number; and “bus” stands for bus number.
ha attach number ID lun bus
a10 Stp 0 2 0 0
a10 Sdsk 0 0 0 0
a10 Srom 0 5 0 0
4. Rebuild the UNIX kernel: Type “. /link_unix <ENTER>”.
5. You have completed the link procedure for the Adapter’s device driver. Exit
and reboot the system.
