Netbackup 7.6 Master Server支持6.5 client吗？

vinciho

请问，Netbackup 7.6 Master Server支持6.5 client吗？
因为客户端服务器是32位的RHEL AS 4，无奈NBU 7不支持32位，所以装了6.5的client，但是貌似连接上有问题，socket write failed，请问能解决吗？

从master server上对6.5的client进行连接性测试，结果如下：

找到原因了，client OS的/etc/hosts文件上得加上Server的域名解析。
不过，有些奇怪，新装的solaris的客户端都没修改/etc/hosts文件，照样OK运行的。

牛奶加蛋

哈，找到原因就好，nbu是按照hostname解析的
所以建议实施前都需要修改host文件的
master是支持版本向下兼容的
