Hi,
Is there an option to disable saving of system dump when a user invokes a kernel panic
using sysdumpstart command.
Also, is there any other way of invoking a kernel panic other than using
sysdumpstart?
Thanks,
Kanna

Nope, the sysdumpstart command is solely there for writing a sysdump. Only root can use this command and therefore it should not be a problem. If you never ever want a dump try to use /dev/null as sysdumpdevice.
You can invoke a kernel panic by shutting down an LPAR with "immediate" from HMC/IVM.
Thanks shockneck..
But the sysdumpdev -p /dev/null is giving the following error,
#sysdumpdev -p /dev/null
0453-050 /dev/null is not a valid dump device.

I just realised that the target should not read /dev/null but /dev/sysdumpnull. Try this.
