- ~~~~~~~~~~
-Chassis_id is a callout program which is used to give geographic names to devices. It uses
-another callout program scsi_id to determine the serial number of a device and then looks up
-the provisioning table based on this key. It retrieves geographic information
-( chassis#, slot# and host# ) about the device and prints it to stdout. These fields are
-used by udev to create the device entry.
-
-Using Udev:
-~~~~~~~~~~
-Chassis_id gets invoked by udev using the udev as below:
-
-BUS="scsi", PROGRAM="/usr/local/bin/chassis_id", NAME="/chassis%c{1}/slot%c{2}/host%c{3}/disk-%c{4}
-
-The provisioning table ( file provision.tbl ) has to be put in /usr/local/bin and as of now has
-to be populated manually. This is the only place where the geographic map of devices is kept
-in the system.
-
-
-Usage Model:
-~~~~~~~~~~~~
-On ATCA based blade architecture systems, blade insertion/removal is common. We create names
-in a 3 level deep tree which represent the geographic map of the devices.

-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.
