~~~~~~~~~~
|
||||
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.
