sun工作站启动时，出现ECC ERROR?

怎么办？

你感觉ECC应该是哪的问题？出点问题就不知道咋办了？

内存问题吧

dcqzy

应该是内存问题,现在的内存有ecc校验

风之幻想

问题出现在你的内存上.

做个post，然后看具体的内容

ok状态那，敲命令也不管用。不好意思，我不太熟悉系统。
有朋友能详细告诉我怎么作吗？

把内存拔下来重新插一下，不行就换吧

ECC （错误纠正码） 用于系统内所有的数据链路上以确保数据完整性，系统会报告和记录可纠正的ECC error.
如果在系统日志中很频繁的看到ECC Error建议更换硬件. 偶尔出现的错误不需要太紧张, 他表示 system meets single-bit error, and system corrected it.  For details, please refer to excerpt from Sun document.

Error correcting code (ECC) is used on all internal system data paths to ensure high
levels of data integrity. All data that moves between processors, memory, and PCI
bridge chips have end-to-end ECC protection.
The system reports and logs correctable ECC errors. A correctable ECC error is any
single-bit error in a 128-bit field. Such errors are corrected as soon as they are
detected. The ECC implementation can also detect double-bit errors in the same
128-bit field and multiple-bit errors in the same nibble (4 bits).
In addition to providing ECC protection for data, the system offers parity protection
on all system address buses. Parity protection is also used on the PCI and SCSI
buses, and in the UltraSPARC III CPU’s internal and external caches.

内存拔下，又装上就好了。
