Hello all,

we have an 8GB LV for the primary dump device on a pSeries 690, 32 proc,
64GB mem system, sysdumpdev reports that the current kernel could
generate an uncompressed dump of apprx. 1.2 GB.

Is 2GB a safe size for the primary dump device? Note that the dump would
be compressed.

Could I just redefine the dump device to be of a smaller size without a
reboot or requiring the system to be in singel user mode?

thanks
Michael Thomadakis

You can remove the current dump device and make a new one. Just
be sure to use sysdumpdev -e output from a busy system.
