AIX操作系统错误日志及日常维护一、系统故障记录(errorlog)errdemon 进程在系统启动时自动运行记录包括硬件软件及其他操作信息故障记录文件为/var/adm/ras/errlog 可备份下来或拷贝到别的机器上分析errpt 命令的使用(普通用户权限也可使用)#errpt |more 列出简短出错信息ERROR_ID TIMESTAMP T C RESOURCE_NAME ERROR_DESCRIPTION192AC071 0723100300 T 0 errdemon Error logging turned off0E017ED1 0720131000 P H mem2 Memory failure9DBCFDEE 0701000000 T 0 errdemon Error logging turned on038F2580 0624131000 U H scdisk0 UNDETERMINED ERRORAA8AB241 0405130900 T O OPERATOR OPERATOR NOTIFICATIONTIMESTAMP: MMDDHHMMYY (月日时分年T 类型: P 永久; T 临时; U 未知永久性的错误应引起重视C 分类: H 硬件; S 软件; O 用户; U未知#errpt -d H 列出所有硬件出错信息#errpt -d S 列出所有软件出错信息#errpt -aj ERROR_ID 列出详细出错信息# errpt -aj 0502f666 <--- ERROR_ID用大小写均可，例：LABEL: SCSI_ERR1ID: 0502F666Date/Time: Jun 19 22:29:51Sequence Number: 95Machine ID: 123456789012Node ID: host1Class: HType: PERMResource Name: scsi0Resource Class: adapterResource Type: hscsiLocation: 00-08VPD: <--- Virtal Product DataDevice Driver Level.........00Diagnostic Level............00Displayable Message.........SCSIEC Level....................C25928FRU Number..................30F8834Manufacturer................IBM97FPart Number.................59F4566Serial Number...............00002849ROS Level and ID............24Read/Write Register Ptr.....0120DescriptionADAPTER ERRORProbable CausesADAPTER HARDWARE CABLECABLE TERMINATOR DEVICEFailure CausesADAPTERCABLE LOOSE OR DEFECTIVERecommended ActionsPERFORM PROBLEM DETERMINATION PROCEDURESCHECK CABLE AND ITS CONNECTIONSDetail DataSENSE DATA0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000二、控制面板上的LED 代码.8 位代码通常系统故障灯会同时亮起某些机型还会同时显示故障设备位置代码.4 位代码通常是Exxx.3 位代码通常为0yyy 只看后3位.8 位和4位代码可查看系统服务手册 (Service Guide)3 位代码可查看系统诊断手册(Diagnostic Information for Multiple BusSystem).闪动的 888, 系统崩溃硬件或软件原因造成按reset 键会显示更多内容888-102 一般为软件故障888-102-207 例外系统会产生一个dump888-102-xxx-0C9 系统正在做dump, 请等待888-102-xxx-0C0 系统dump完成可关电重启888-103 或 105硬件故障一般有 SRN 代码及位置代码三、其他用于收集系统信息的命令lsdev -C 系统设备信息#lsdev -Cc diskhdisk0 Available 00-06-00-2,0 4.5 GB 16 Bit SCSI Disk Drivehdisk1 Available 00-06-00-1,0 4.5 GB 16 Bit SCSI Disk Drivehdisk2 Defined 00-06-00-4,0 16 Bit SCSI Disk Drivelspv 查看物理卷信息#lspvhdisk0 0007821160af3d76 rootvghdisk1 000782117f571294 rootvghdisk2 0000000045c45bde datavglsvg 查看卷组信息#lsvg datavgVOLUME GROUP: datavg VG IDENTIFIER: 0000000055e2458bVG STATE: active PP SIZE: 4 megabyte(s)VG PERMISSION: read/write TOTAL PPs: 2169 (8676 megabytMAX LVs: 256 FREE PPs: 1 (4 megabytes)LVs: 3 USED PPs: 2168 (8672 megabytOPEN LVs: 2 QUORUM: 2TOTAL PVs: 1 VG DESCRIPTORS: 2STALE PVs: 0 STALE PPs: 0ACTIVE PVs: 1 AUTO ON: yesMAX PPs per PV: 2032 MAX PVs: 16#lsvg -l rootvgrootvg:LV NAME TYPE LPs PPs PVs LV STATE MOUNT POINThd5 boot 1 1 1 closed/syncd N/A...lv00 jfs 51 102 1 closed/stale /ibmcxxlv01 jfs 1 1 1 open/syncd /cics_regionslv02 jfs 4 4 1 open/syncd /var/mqmlslpp 查看文件组信息# lslpp -L |grep 23100020....devices.pci.23100020.rte 4.3.2.7 C IBM PCI 10/100 Ethernet Adapt看某个文件组是否已安装如以太网卡驱动也用于查询补丁程序的版本lsattr 查看设备参数设置# lsattr -El ent2busio 0x7fffc00 Bus I/O address Falsebusintr 9 Bus interrupt level Falseintr_priority 3 Interrupt priority Falsetx_que_size 512 TRANSMIT queue size Truerx_que_size 256 RECEIVE queue size Truerxbuf_pool_size 384 RECEIVE buffer pool size Truemedia_speed 10_Half_Duplex Media Speed Trueuse_alt_addr no Enable ALTERNATE ETHERNET address Truealt_addr 0x000000000000 ALTERNATE ETHERNET address Trueip_gap 96 Inter-Packet Gap Truelscfg 查看VPD信息Virtual Product Data)# lscfg -vl ssa1DEVICE LOCATION DESCRIPTIONssa1 30-68 IBM SSA Enhanced RAID Adapter(14104500)Part Number.................097H0645FRU Number..................097H0645 <-- 备件号Serial Number...............C8217227EC Level....................0000F20825Manufacturer................IBM053ROS Level and ID............7201 <-- 微码版本Loadable Microcode Level....04Device Driver Level.........00Displayable Message.........SSA-ADAPTERDevice Specific.(Z0)........DRAM=032Device Specific.(Z1)........CACHE=0Device Specific.(Z2)........000000062955dab2Device Specific.(YL)........P2-I7 <-- 槽号不同的硬件设备有不同的VPD 所含的格式和信息都不一样通常备件号和微码版本最有参考价值注FRU(Field Replace Unit)才是真正的备件号。
