Memory for Crash Kernel

Hi_This_is_Dev · 09-07-2009, 07:33 AM

Hi,

When Red Hat EL 5 starts up is displays this info:

Code:

Memory for crash kernel (0x0 to 0x0) not within permissible range

What does it (memory for crash kernel) mean?

What to do so as not to get that info?

Is kdump related to it?

Thanks!

Yes, it's related to kdump. You can find this message in the RedHat knowledgebase, and a good explanation of what causes it. You should have access to it, since you're paying for RedHat Enterprise.....

Thanks for the confirmation! I will post my findings here.

So, as suggested by you, I searched knowledgebase at redhat.com and found useful info here:
