TS_NIM_ERROR_RDWR_E报错解决方法
环境 Pseries AIX HACMP 问题 当hacmp运行的情况下，在errpt里看到许多TS_NIM_ERROR_RDWR_E的报错： LABEL: TS_NIM_ERROR_RDWR_E IDENTIFIER: 90D3329C Class: S Type: PERM Resource Name: topsvcs Description NIM read/write error Probable Causes Topology Services Network Interface Module (NIM) error: Read error while trying to retrieve packets Write error while trying to send packets Failure Causes Lack of 'mbufs' Network is down I/O errors while accessing heartbeating device Remote side is not present Detailed Data Interface name tty0 解答 1.停止HACMP服务 smit clstop-->graceful 2.检查串口心跳设备tty0是否被别的进程占用 fuser /dev/tty0-->kill any process using tty0 3.检查两个节点的tty0的联通性 cat /dev/tty0"-->ok 4.改变tty0的baud rate为9600 smit chtty-->everything is correct for tty0 on both nodes 5.将hacmp心跳网络的parameter改为9600 smit hacmp?extended config?topology config?network module? Custom Values?Parameter=9600 6. 如果上述方法还是不能解决问题，如果节点间有复用器的话，请确保复用器的设置正常
