+Udev does not come pre-installed on a Linux system. Hence, we need to do the following before
+a Linux system is ready ::
+
+Steps:
+~~~~~
+1.  Install libsysfs shared libraries by installing sysfsutils-0.4.0.
+
+2.  Download latest version of udev from www.kernel.org site. It is
+    under repository->utils->kernel path chain.
+
+    Do make and make install so as to install udev. To install scsi_id,
+    go into extras/scsi_id folder to compile scsi_id. Typically, this
+    would be in /sbin folder.  Now, change scsi_id.cfg and set the
+    global option to work with all devices ( -g) and comment out the
+    black list option ( -b ).
+
+3.  Download chassis_id callout code and compile. Install chassis_id and
+    provision.tbl file in /usr/local/bin.
+
+4.  In /etc/rc.sysinit, add mount command to mount the sys memory file
+    system. ( mount -t sysfs sys /sys ). The /sys is necessary as
+    lot of the software components expect it to be in /sys.
+
+5.  Now, in /etc/udev/udev.rules, install the udev rules file. This
+    is the GDN config file which is used by udev to create folders
+    in the form chasis<N>/slot<M>/port<O>/disk<P>.
+
+6.  Now, you are almost there. Refer to PROVISIONING file.
+
+
+PROVISIONING:
+1.  For GDN, the provisioning file is in the format :
+   <id>  <host>   <number_of_disks>     <chassis#>    <slot#>  <serial#>  <name>
+
+   <host>            SCSI host on which the device is connected
+   <Number of disks> how many disks on this blade ?
+   <chassis#>        chassis Number
+   <slot#>           Physical slot number
+   <serial#>         Serial Number for the disk
+   <name>            Name of the disk device.
+
+2.  To fill the provisioning table, the user needs to collect this information and
+    fill provision.tbl.
+
+    The serial number is found from the command scsi_id -p 0x80 -s <device name>.
+
+    The host number is availble from the sys file system. The chassis & slot
+    are visual data and should be enetered into provision.tbl.
