大家都知道在AIX中alog可以显示并且更改那些在alog数据库中配置的日志文件。但是我们在系统中能够查看到哪些有用的日志呢？

我们可以用alog -L的命令找到答案：

# alog -L
boot
bosinst
nim
console
cfg
mdmplog
lvmcfg
lvmt
dumpsymp

对于每一个日志的更多信息还可以通过-t和-L的配合查看：

# for i in $(alog -L); do echo "\n$i:\n";alog -t $i -L ;done
boot:
#file:size:verbosity
/var/adm/ras/bootlog:131072:1
bosinst:
#file:size:verbosity
/var/adm/ras/bosinstlog:8192:1
nim:
#file:size:verbosity
/var/adm/ras/nimlog:131072:1
console:
#file:size:verbosity
/var/adm/ras/conslog:32768:1
cfg:
#file:size:verbosity
/var/adm/ras/cfglog:1048576:1
mdmplog:
#file:size:verbosity
/var/adm/ras/mdmplog:4096:1
lvmcfg:
#file:size:verbosity
/var/adm/ras/lvmcfg.log:51200:3
lvmt:
#file:size:verbosity
/tmp/lvmt.log:204800:3
dumpsymp:
#file:size:verbosity
/var/adm/ras/dumpsymplog:65536:1

lvmcfg日志就是一个非常有用的东西，它能记录你每一次执行LVM操作的命令，如果碰到LVM的问题怀疑有人动过的话，就可以通过它来查看。

例如，查看LVM命令操作记录：

# alog -o -t lvmcfg | grep -vE "workdir|exited|tellclvmd"
