TITLE    : Procedure to create a dummy "defined" hard drive
OS LEVEL : AIX 4
DATE     : 03/03/99
VERSION  : 1.0

----------------------------------------------------------------------------

In this example hdisk1 is being created with a scsi id 2, on a machine 
that only has hdisk0 at scsi id 6.

1, mknod /dev/rhdisk1 c 12 2
2, mknod /dev/hdisk1 b 12 2

To check that the files have been created correctly, the output of
ls -l /dev/*hdisk* should look simular to :-

brw-------   1 root     system    12,  1 28 Oct 16:56 hdisk0
brw-r--r--   1 root     system    12,  2 03 Mar 11:02 hdisk1
crw-------   2 root     system    12,  1 28 Oct 14:15 rhdisk0
crw-r--r--   1 root     system    12,  2 03 Mar 11:02 rhdisk1

3, odmget -q "name=hdisk0" CuDv > /tmp/hdisk1.CuDv
4, odmget -q "name=hdisk0" CuAt > /tmp/hdisk1.CuAt
5, vi /tmp/hdisk1.CuDv 

The example below has been amended to the new drive settings.

CuDv:
	name = "hdisk1"
	status = 0
	chgstatus = 2
	ddins = "scdisk"
	location = "00-00-0S-2,0"
	parent = "scsi0"
	connwhere = "2,0"
	PdDvLn = "disk/scsi/osdisk"

Note :- name is changed to the new disk name
        status is changed from 1 (available) to 0 (defined)
        location is changed to suit the scsi address of the new drive
        connwhere is changed as per the new scsi address

6, vi /tmp/hdisk1.CuAt

The example below has been amended to the new drive settings.

CuAt:
	name = "hdisk1"
	attribute = "pvid"
	value = "0020108512334d350000000000000000"
	type = "R"
	generic = "D"
	rep = "s"
	nls_index = 2

Note :- name is changed to the new disk name
        just change one of the numbers in the value field, this field is
        the serial number of the drive and needs to be unique to the system

7, odmadd /tmp/hdisk1.CuDv
8, odmadd /tmp/hdisk1.CuAt

To check that the new drive has been created correctly, the output of command
lsdev -Cc disk should look like :-

hdisk0 Available 00-00-0S-6,0 Other SCSI Disk Drive
hdisk1 Defined   00-00-0S-2,0 Other SCSI Disk Drive

Any new disks that are added to the system (not at scsi id 2) will now be
numbered from hdisk2 onwards. To deleted hdisk1 :-

rmdev -l hdisk1 -d
