HPUX MC问题,急!
机器掉电后cluster就起不来了想重新验证或重新配置,结果都报错..
# cmcheckconf -k -v -C /etc/cmcluster/cmclconf.ascii
Checking cluster file: /etc/cmcluster/cmclconf.ascii
Note : a NODE_TIMEOUT value of 2000000 was found in line 128. For a
significant portion of installations, a higher setting is more appropriate.
Refer to the comments in the cluster configuration ascii file or Serviceguard
manual for more information on this parameter.

查看syslog,发现报
host1 cmclconfd: Unable to open /dev/urandom (No such dev
ice).
host1 cmclconfd: Error, tried to create a cmclconfd token with 64 bytes and only generated 0 bytes. 先用ping host1/host2测试网络是否正常。
看看是不是手动修改过IP地址/主机名，网卡是否工作正常。 都ping的通,工作也正常... host1 cmclconfd: Unable to open /dev/urandom (No such dev
ice).
手工创建这个文件。 检查网络和共享存储
回复 1楼 gxjyyy 的帖子
unable connect to host:Pls try to check end to end connection:
vi /etc/hosts
vi ./rhosts
ping host1
ping host2
nslookup host1
nslookup host2
nslookup host1ip
nslookup host2ip
rlogin host1
rlogin host2
confirm the lock vg status 恩.应该是/etc/hosts和/.rhosts 文件的问题
