informix问题求助

ibu

今天onstat -d发现datadbs呈PD状态，察看日志发现有张表vip:"otv8".cont_clist_otv8存在问题，导致chunk028出现了IO错误。
     尝试着把chunk028拉起，失败，报
$ onspaces -s datadbs -p /dev/rchunk028 -o 128 -O -y
Verifying physical disk space, please wait ...
Cannot change chunk status.
ISAM error:  illegal argument to ISAM function.

参考下面的方法照做，还没发现其它什么好方法。如果没有备份的话，GOD　BLESS　YOU！

遇到过类似的问题，IDS版本升级到9.4就解决了。
