HACMP 资源接管测试中的一个疑惑

jaix

配完ha后，在测试双机资源接管时，
用＃shutdown －Fr 关掉主机，备机不能接管资源
用＃halt －q 关掉主机，备机能正常接管资源

有人能解释一下这是什么愿因吗？

/usr/es/sbin/cluster/etc/rc.shutdown

shutdown －Fr 是正常关机重启，备机当然不能接管。
halt -q 是立即关机，相当于模拟机器掉电而宕机的情况，所以备机会认为主机有故障而去接管。

刚在redbook上找到了解释

When the AIX 5L operating system is shut down (with the shutdown command) while cluster
services are running, the processing in the /usr/es/sbin/cluster/etc/rc.shutdown performs a
forced shutdown. If you prefer to have resources taken over, then prior to issuing the AIX 5L
shutdown command, stop HACMP with a graceful with takeover option. If you do not care
to have resources taken over, take no special action.
Note: HACMP resource group location information may not be updated
properly as a result of a forced down or an inadvertent shutdown.
When the forced node is reintegrated into the cluster, the displayed
cluster resource group location will be refreshed.

把这个脚本打开看看就知道了

不符合脚本的情况说明有bug，这种乱子hacmp也出过

楼上的说法是正确的。呵呵。

当然了 一个是正常关机
一个是模拟宕机 两个概念不通
