【HPUX 11.31专题】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：

-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.
Completed network probing
Failed to gather configuration information.

 

同时发现rcp远程复制没响应：

/tmp/vgdata.map hpvm2:/tmp/

执行过程中一直处于停滞状态，没有任何响应。

 

检测文件包括/etc/hosts、.rhosts、/etc/hosts.allow均没有任何问题，相互之间能够ping通：

经同事协助调查，发现问题出在/etc/inetd.conf文件下，很多地方因为安全限制被屏蔽，如下所示：

把这些注释符统统打开，然后重启inetd进程，再尝试rcp远程复制操作，或者重新通过“cmquercl”命令检测两个节点的通信，问题解决。
