Policy wise, we have shied from scripting CLI commands as in many cases human factors concerns can cause changes that break parsers (see struggles in xCAT 1.x with different Cisco CatOS firmware levels changing layout of various commands). The SNMP interfaces of these same systems are largely immune to this sort of concern. I'm not aware of BladeCenter experiencing a CLI change, but I also haven't been looking too hard.
Conversely, since xCAT is not the only consumer of the SNMP interface, improving the AMM behavior is the correct course anyway. Given that we are endeavoring to correct the slowness, a blade plugin rewrite would likely complete after the SNMP interface is hopefully working better again and the effort would be largely moot.

Regrettably, SNMP commands involving LED requests can take up to 5 minutes to be fulfilled by the AMM, during which the AMM will not respond to other SNMP requests. This is under investigation. Non-snmp interfaces are not impacted by this behavior. Arif Ali ---11/01/2011 06:46:51 PM---Hi all, not sure if anyone is aware of this.

It seems that the rbeacon on the bladecenter causes the bladecenter AMM to become unresponsive for about 5-10 seconds. rpower group stat works every single time, but rbeacon group on, would hang on the initial nodes and work ok on the rest.
