sco下informix 0级备份失败,为什么?

wuyong

我通过ontape -s -L 0做0级备份
现象：
。。。。。。
60 percent done.
Archive failed function write to tape failed code -1 errno 6
program over


informix下的online.log显示：
12:03:13 Level 0 Archive started on rootdbs, logdbs, datadbs, rev_premdbs, insu
rdbs
12:08:25 Checkpoint Completed: duration was 0 seconds.

14:25:54 Aborted by client.
14:26:07 Checkpoint Completed: duration was 0 seconds.
磁带容量24G,informix下onconfig设置：
TAPEDEV /dev/rct0 # Tape device path
TAPEBLK 20 # Tape block size (Kbytes)
TAPESIZE 20480000 # Maximum amount of data to put on tape (Kbytes
)
设置应该正常，0级备份只有中午做失败，晚上做成功！
原因在SCO上，还是INFORMIX?
请各位帮忙解决！

会不会是你的磁带容量大小设置有问题，建议设置小一些，准备两盒空磁带进行备份

很像是磁带机的问题
