p630不能启动，请各位大侠救急！！！

ci-ci

主机（IBM P630）能ping通，但telnet、ftp、rlogin均不成功，控制台也无法进入系统，关闭电源重启，系统不能启动，LED显示0518，用diag盘诊断硬盘，没有报错。用安装判引导至维护模式下，进入access rootvg and start a shell befor mounting filesystems并fsck所有的文件系统，开始/dev/hd4报”error detected in the file system inode allocation map”错误，再次fsck后没有报错，但启动时仍然停留在0518处。

1、        拔出hdisk1保留hdisk0，重启主机，系统停留在0557处
用安装盘引导到维护模式下，
进入access rootvg and start a shell befor mounting filesystems

只放hdisk1，进入维护模式，完成了fsck之后，你可以用

#bosboot -ad /dev/hdisk1重建boot image试试！

可能是硬盘数据损坏，系统设置文件出错，或I/O子系统故障或文件系统损坏 ，文件系统日志(jfslog)损坏

用系统光盘或系统备份带启动

格式化文件系统日志(jfslog)
# /usr/sbin/logform /dev/hd8

检查修复文件系统
# fsck -y /dev/hd1 （/home 文件系统）
# fsck -y /dev/hd2 （/usr 文件系统）
# fsck -y /dev/hd3 （/tmp 文件系统）
# fsck -y /dev/hd4 （/ 文件系统）
# fsck -y /dev/hd9var （/var 文件系统）
... ...
文件系统会 mount 起来。

重建bootimage
# lslv -m hd5 找出bootimage所在的硬盘，如hdisk0
# bosboot -ad /dev/hdisk0
# bootlist -m normal /dev/hdisk0 重建启动顺序表。
重启动系统
# shutdown -Fr

按你的方法作了，存在如下疑问
1、文件类型是jfs2，logform是否会导致文件系统数据丢失
2、行内日志和行外日志分别是什么意思
3、维护模式下没有bosboot命令
4、fsck所用的文件系统后用exit命令退出
显示：
AFopen failed: No such file or directory
AFopen failed: No such file or directory
AFopen failed: No such file or directory
mount : Could not table filesystem data
mount :There is no plausible log device for /dev/hd2 ("/usr"
The mount of /dev/hd2 did not succeed.

请问还有什么解决办法？
谢谢

使用logform不会影响文件系统内容。根据你的情况，可能是因为日志卷导致的问题。

可以新建一个日志卷，然后在维护模式下面，logform <log vol>;，并修改/etc/filesystem定义/dev/hd2的log指向新的<log vol>;

启动以后，你最好检查一下dump，把errpt贴出来，查出导致down机的原因。

请问在维护模式下怎么建lv，怎么修改/etc/filesystem文件。
谢谢
