sybase双机热备切机后数据库设备无法加载，急！
各位大牛，请帮帮小弟吧，都快急死了！非常感谢！
我们有两台sun服务器a和b，共用一个磁盘阵列，sybase ASE12.5。以前磁盘阵列挂在a上，由于cpu风扇有问题，停了a机（在关机过程中忘了关数据库），数据库自动cluster到b机后几个设备无法初始化，报sybase 840错误。
我是初学者，照着网上的资料查了一下，现在数据库的情况如下：
1.重新把磁盘阵列挂到a机上数据库仍能正常运行
2.我们的所有库文件都在磁盘阵列上（master也在）
3.以前在a机上对数据库进行扩容，但好像b机的.cfg文件也相应修改过
4.其中出问题的scbjhdb库的status为64
5.在sysdevices中出问题的设备都能看到
6.曾在b机上用 fsck -y 检查磁盘阵列文件，但由于时间不够，最后修复中断了
敬请各位大牛给我看看，有啥好办法没有。
