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.
