数据库启动不了了

增加了系统的内存，于是ASE启动不了了，显示以下信息：

希望给点意见。
谢谢

Error: 823 一般是由硬件错误引起的，先检查硬件十分有问题

master都起不来了，问题很严重。

看来在系统做变化之前备份数据库很重要哦，
加条内存就出问题了

Error 823 description in sybase manual:
Note This error may be caused by a hardware problem.
This error occurs when Adaptive Server encounters an I/O error on a read or
write request made to a Sybase device. It usually means you have disk
problems. The parameters in the error message refer to internal Sybase
structures and do not often help determine which device is involved. However,
additional kernel messages in Adaptive Server's error log
