Problem Solved (Booting From Local Hard drive)
Hello...
I have a Linux Cluster of 64-nodes with
OSCAR version: 4.1
Linux Distro: Red hat 9
Pxelinux version: 2.00
There is a problem which Im trying to solve for almost a week but still
no results.
When I boot a client from the network, after finishing successful
installation from the network, it reboots.
After the reboot it tries to boot from the Local Hard drive.
B/e I changed the /etc/systemimager/systemimager.conf and set
NET_BOOT_DEFAULT = LOCAL. (This was stated in an article, link http://www.wiki.sisuite.org/networkboot )
The netbootmond also restart after the item changed.
But it hangs there! And do nothing after that i.e. after the
message
Trying to get: pxelinux.cfg/COA70133
Booting from Local Hard drive
I dun understand why this happens.
Solution:
While I was searching for the solution of this problem, I saw almost same problem posted on syslinux users mailing lists. Here is the link (http://syslinux.zytor.com/archives/2007-February/008075.html ) and this problem got solved by installing new version of Pxelinux bootloader.
Since I was using version 2.00 of pxelinux, so I thought to upgrade it to syslinux-3.36
I downloaded syslinux version 3.36 from this link (http://www.kernel.org/pub/linux/utils/boot/syslinux/)
This was syslinux-3.36.tar.gz , so I untared it using the command (tar xvzf )
Then I copied pxelinux.0 ( from syslinux-3.36) to /tftpboot , but before copying the new file, I made a backup of the old pxelinux.0 of pxelinux version 2.00 ( b/e I wanted to check if there was some problem in the old version or not)
After pxelinux bootloader got upgraded to new version, I rebooted the client.
The client tried to boot from the local hard drive after configuring itself from the network, it waited a couple of secs and LILO came up! And all was good.
For checking if there was really some problem with the old version, I again replaced the backup file of pxelinux.0 from the new pxelinux.0 file.
Rebooted the client, it tried to boot from the local hard drive after configuring itself from the network, but it again got stuck there!
So there was problem with the pxelinux old version bootloader (version 2.00) as it never allows the client to boot from the local hard drive after it configures itself from the network.
Im Thankful to all of those who suggested me solutions to this problem.
Best Regards,
Hiba
