安装HDR出现的问题

大家好！安装配置HDR时备机出现：
08:18:04  Maximum server connections 0
08:27:43  DR: Reservation of the last logical log for log backup turned off
08:27:43  DR: new type = secondary, primary server name = kaohe
08:27:43  DR: Trying to connect to primary server = kaohe
08:27:43  DR: Cannot connect to primary server
08:27:43  DR: Turned off on secondary server
08:27:43  Cannot create SMX pipes


RSH,RLOGIN都正常，信任关系正常，SQLHOSTS正常的。

还有查了一下资料，第一步安装 UDR、UDT 和 DataBlade 模块。请问是什么意思？要怎么做，谢谢！收起
