求助：INFORMIX数据库0级备份的报错，各位大大帮忙看看

wushanyink

某局点，在进行0级备份的时候，提示如下错误：

Please mount tape 1 on smp2:/dev/rmt/0m and press Return to continue ...
10 percent done.
20 percent done.
30 percent done.
40 percent done.
50 percent done.
60 percent done.
70 percent done.
Archive failed - function write to tape failed code -1 errno 32
dd: unexpected short write, wrote 0 bytes, expected 65536

Program over.

PS：该磁带机正常，磁带也换了N个，问题依旧

环境：
SUN 5.8
Cluster 3.0
Informix 7.31UD6W5

另：该套系统前几天曾经切换过一次，informix重新启动过，启动后的第一天进行0级备份的时候，一切正常，但第二天进行备份就有问题了。

麻烦各位帮忙看看是什么问题，谢谢了。

It is failed to do the informix backup in the platform, when we try to do the backup, it give the below error mesage.

Please mount tape 1 on smp2:/dev/rmt/0m and press Return to continue ...
10 percent done.
20 percent done.
30 percent done.
40 percent done.
50 percent done.
60 percent done.
70 percent done.
Archive failed - function write to tape failed code -1 errno 32
dd: unexpected short write, wrote 0 bytes, expected 65536

In online.log, we can't see anything related to this error, it give us the prompt message:
"Achive aborted." only.

We tried several method to solve the problems.
1, to use the tape drive in other machine, still failed.
2, to restart the informix server, it can work for 1-2 days, then failed again.

I am sure this platform's tape driver is OK

帮转下，多谢廖总。。

用这个远程流带机的问题!
估计是支持不好!以前遇到过!
