HPUX 11.31 心跳检测失败、rcp远程复制失败解决办法

HPUX 11.31 心跳检测失败、rcp远程复制失败解决办法 在HPUX 11.31操作系统下配置双机，在执行“cmquercl”检测节点通信的时候报错，错误症状如下: root@hpvm1:/#cmquerycl -n hpvm1 -n hpvm2 -v -C /etc/cmcluster/cmclconf.ascii Warning: Unable to determine local domain name for hpvm1 Looking for other clusters ... Done Gathering storage information Unable to connect to node hpvm1: Permission denied Unable to connect to node hpvm2: Permission denied Gathering network information Beginning network probing Not probing node hpvm1 as it is currently unreachable. This may cause network partitions to be reported. Not probing node hpvm2 as it is currently unreachable. This may cause network partitions to be reported.
