## snmp for monsetting to remove blade settings from blade when trap is recieved
## example:
## 1. user removes a blade from the chassis
## 2. snmp trap setup to point here
## 3. this script removes the blade configuration from xCAT
## 4. so if blade is placed in new slot or back in then xCAT goes
## through rediscover process again.
