Hi all,
I am using SCO Openserver V and I want to add one more harddisk (/dev/hd1) Hw can I do it?
You add a hard drive, and configure the file systems on it, by running "mkdev hd". If you are curious as to what goes on behind the scenes, look in /usr/lib/mkdev. The "hd" command there is a shell script, and is fairly self-explanatory. You generally have to run 'mkdev hd' twice. If I remember correctly, the new kernel already has the code for the second IDE drives, so in that case it's only once. But for SCSI drives, the first invocation puts the driver code in, and the second (after a reboot) allows the partitioning and division of the drive.
For SCSI drives, the first pass asks you the name of the SCSI controller. If you don't know, and if your primary drive already is SCSI, look in /etc/conf/cf.d/mscsi.
