NOTES

1. Diskdump support for RHEL 4.0 & RHEL 3.0 (Except GA, U3)

Suggested steps to Test Diskdump support :

i. Ensure that the megaraid_sas driver is loaded and you have at least one LD
ii. modprobe diskdump
iii. In /etc/sysconfig/diskdump file specify dump device partition. Example, DEVICE=/dev/sdb1, where sdb1 is the partition in a LD
iv. service diskdump initialformat (Formats the dump partition)
v. chkconfig diskdump on (To enable the service)
vi. service diskdump start
vii. cat /proc/diskdump (To see if diskdump has been activated). It should show the registered dump device (e.g. /dev/sdb1 in the last line of output)
viii. Trigger a kernel panic : 
a. For RHEL 4.0: Alt-SysRq-c or  echo c >/proc/sysrq-trigger
b. For RHEL 3.0: 1. echo 1 > /proc/sys/kernel/sysrq   2. Alt-SysRq-d / Alt-SysRq-c
ix. After you see that the dump operation is complete, reboot the system
x. On the next reboot sequence a vmcore file will be created in /var/crash/127.0.0.1-<date>
You may use crash command to analyze. Example crash vmlinux vmcore, where vmlinux is the uncompressed kernel image.

2. add new IOCTL memory management module to the driver.
