Symptoms
尝试使用以下命令：
symrcopy -file filename.txt create -copy -name COPY_NAME -pull -hot -nop 'Create' operation execution is in progress for the device list in device file 'filename.txt'. Please wait... The REMOTE Copy 'CREATE' operation FAILED. (SYMAPI_C_RCOPY_DISCOVER_ERROR) An rcopy remote device discover error occurred
在 SYMAPI 日志中：

Cause
发生此问题的原因是 XIO 设备上的数据块大小为 4096。而 "symsan list -sanluns" 命令输出显示设备的数据块大小：
Symmetrix ID: 000xxxxxxxxx
Remote Port WWN: xxxxxxxxxxxxxxxx

此问题并不会影响系统的正常工作。Open Replicator 不支持 4096 块大小设备。
