alog command and odm

用alog命令可以查看一下日志：
/var/adm/ras/bootlog
/var/adm/ras/BosMenus.log
/var/adm/ras/bosinst.log
/var/adm/ras/nimlog
/var/adm/ras/conslog
/var/adm/ras/errlog

查看boot log：
root@wjlcnaix:/>alog -o -t boot |more
********** no stdout ***********
****************** no stderr ***********
----------------
Time: 13        LEDS: 0x538
invoking top level program -- "/usr/sbin/lsdev -C -c management -s infiniband -t icm -F name"
Time: 13        LEDS: 0x539
return code = 0
****************** no stdout ***********

通过smit查看

要将新的日志类型 kakatest 添加至 alog 配置数据库，请以下列格式创建 kakaalog.add 文件：

SWservAt:
    attribute="alog_type"
    deflt="kakalog"
    value="kakalog"
 

SWservAt:
    attribute="kakalog_logname"
    deflt="/tmp/kakatest.log"
    value="/tmp/kakatest.log"
 

SWservAt:
    attribute="kakalog_logsize"
    deflt="81920"
    value="81920"
 

SWservAt:
    attribute="kakalog_logverb"
    deflt="1"
    value="1"



在创建了 kakaalog.add 文件后，请输入：


odmadd kakaalog.add
这将 alog.add 文件添加至 SWservAt 数据库。
root@wjlcnaix:/tmp>odmadd kakaalog.add
root@wjlcnaix:/tmp>odmget -q "attribute like '*kaka*'" SWservAt

SWservAt:
        attribute = "kakalog_logname"
        deflt = "/tmp/kakatest.log"
        value = "/tmp/kakatest.log"

SWservAt:
        attribute = "kakalog_logsize"
        deflt = "81920"
        value = "81920"

SWservAt:
        attribute = "kakalog_logverb"
        deflt = "1"
        value = "1"

root@wjlcnaix:/tmp>ls -l kaka*
-rw-r--r--    1 root     system          335 Apr 01 10:59 kakaalog.add
-rw-r--r--    1 root     system        81920 Apr 01 10:23 kakatest.log
root@wjlcnaix:/tmp>alog -C -t kakalog -s 4096
root@wjlcnaix:/tmp>echo "changed log size" |alog -t kakalog -s 4096

root@wjlcnaix:/tmp>ls -l kaka*

-rw-r--r--    1 root     system         4096 Apr 01 11:30 kakatest.log

要在 alog 配置数据库中将日志类型 sample 的日志文件的名称更改为 /var/sample.log，请输入：

alog -C -t sample -f /var/sample.log
要将引导日志的大小改为 8192 字节并在 ODM 中反映新大小，请输入：

alog -C -t boot -s 8192
echo "Changed log size" | alog -t boot -s 8192
