请教一个备份问题
操作系统AIX5.2,文件系统JSF2，SYBASE12.5.2 EBF12056

做硬盘dump的时候只能做到下面的字节大小就出错，另外还有一台机器也是在这个问题，字节数一样，似乎有什么限制，但是用sybase用户我能tar出来一个5G的文件，小于1G的内容都能备份成功。
-rw-r--r--   1 sybase1  system   1073741312 Jun 11 03:01 HQS.dmp

dump出错的日志如下：

建一个小的库测试一下,看是SYBASE的问题还是操作系统的问题

shellxie

试过，小于1G的库能备份成功，大于1G的备不出来，机器是HA的

那应该跟系统有关,不是跟SYBASE有关,设置分卷备份吧
