system panic
Especially Bill hassel.....
Can some one tell me if the toc has been missed to create a crash dump in the event of system panic - after the reboot - does the savecrash will create the crash dump is that equal to the other one.
what are the pros and cons of issuing toc when system panic..not really crashed..
Thanks in advance

Re: system panic
The full memory dump is copied to the dump device if the dump device is configured and accessible, next boot it will be transferred to the save crash directory that is what savecrash does, it will not have any ability to generate anything and there is nothing called equvilant.
If it is an HPMC there will be a ts99 dump.
Now you may decide what will happen.
"what are the pros and cons of issuing toc when system panic..not really crashed.."
not really crashed - you are telling it is paniced and hung state, and it is not rebooted.
Other than a toc/reset what else you can do this case? So it doesnt matter what ever the pros and cons !!!!

No, If you haven't given TOC from GSP/MP or system not initiated TOC then you won't be able to get crash dump using savecrash.
Savecrash is to save the system dump from the dump device to filesystem. If dump is not there on dump device, how it will save it to filesystem?

Re: system panic
When you are not doing TOC?
Which state of the server?
If you do a cold reset it will not create crashdump, if you want crash dump you should do a toc.

Re: system panic
If the size of dump or the size of place where crash gets saved (normally /var) is smaller than the size of crash files, it will not create FULL dump.
What about #savecrash -v
