Dump device configuration mode is config_deprecated_mode.
Use crashconf -s option to change the mode.
Physical Memory :
Model: ia64 hp Integrity BL870c i2
Main Memory: 196431 MB
Processors: 16
Currently our dump device is less then, as per physical memory. Due to which, in event of server crash, crash dump is not having enough dump space to store the crash.
Mine question is , Is it possible to use existing swap device as dump device. If yes How?
OS is HP-Unix 11i v3, We had swapoff utility installed in case we need to disable swap.

You should turn on compression, that should help.
But with only 4 GB, not much. :-(
You have way too much device swap. If you have that much memory, you don't need swap.
