Lesson learned while trouble shooting PSOD.

I was working with VMware support and was not able to generate vm-support log. It use to hang after creating folder but not able to tar it.

1. To delete folder and nested folder within without confirmation use

rm – rf

2. Under /root/old_cores you will find dumps created for PSOD , which is required for analysis

-rw-r--r-- 1 root root 3987551 Nov 5 2008 vmkernel-zdump-110508.02.35.1

-rw-r--r-- 1 root root 16883365 Feb 18 13:13 vmkernel-zdump-021810.13.13.1

-rw-r--r-- 1 root root 262144 Feb 19 12:23 vmkernel-log.1

-rw-r--r-- 1 root root 262144 Feb 23 02:17 vmkernel-log.2

3. less /proc/cpuinfo

4. To read vmkernel-zdump-110508.02.35.1

vmkdump -l vmkernel-zdump-021810.13.13.1. This create file

created file vmkernel-log.4

Log wrapped

The log is like this

less Ri vmkernel-log.4

5. dmidecode|less is the other command to manage the information

6. Very informative KB
