I/O 设备物理损坏。2. 到这个I/O外设的硬件连接通道有问题。3. 这个I/O外设被在线移掉（例如：磁带机，DVD-ROM 被在线拔走）。6. 网络(#ioscan nfkClan,#lanscan,#neistat -in) 服务器网络部分的检查，可分三步进行：1. 用命令 #ioscan nfClan，确认所有网络设备（网卡）的状态都是“Claimed“。Class I H/W Path Driver S/W State H/W Type Description=lan 0 0/0/0/0 btlan CLAIMED INTERFACE HP PCI 10/100Base-TX Core /dev/diag/lan0 /dev/ether0 /dev/lan0 2. 用命令#lanscan 查看网卡是否启动。Hardware Station Crd Hdw Net-Interface NM MAC HP-DLPI DLPIPath Address In# State NamePPA ID Type Support Mjr#0/0/0/0 0x00306E0C194A 0 UP lan0 snap0 1 ETHER Yes 119硬件路径 网卡MAC地址 网卡的状态：UP - 启动 DOWN 未启动3. 用命令netstat -in确认网络地址及状态。 Name Mtu Network Address Ipkts Opkts lo0 4136 838 838 lan0 1500 160952 111715 网卡号（有*表明IP层不通） 子网地址 IP地址 接收包数量 发送包数量 7. dmesg 输出 运行命令dmesg 是一个即简单又快捷的方法来查看系统硬件及文件系统有无报错。dmesg 的工作原理是直接从系统的缓冲器(buffer)中读取系统最近一段时期内的硬件状态。 命令dmesg 的缺点是输出结果中没有时间标志， 同时因为缓冲器的容量有限，近期的内容会覆盖缓冲器里以前的内容。 服务器没有硬件报错时，dmesg的标准输出是： May 14 10:38gate64: sysvec_vaddr = 0xc0002000 for 2 pagesNOTICE: autofs_link(): File system was registered at index 3.NOTICE: cachefs_link(): File system was registered at index 5.NOTICE: nfs3_link(): File system was registered at index 6.0 sba0/0 lba0/0/0/0 btlan0/0/1/0 c7200/0/1/0.7 tgt0/0/1/0.7.0 sctl0/0/1/1 c7200/0/1/1.2 tgt0/0/1/1.2.0 sdisk0/0/1/1.7 tgt0/0/1/1.7.0 sctl0/0/2/0 c7200/0/2/0.7 tgt0/0/2/0.7.0 sctl0/0/2/1 c7200/0/2/1.2 tgt0/0/2/1.2.0 sdisk0/0/2/1.7 tgt0/0/2/1.7.0 sctl0/0/4/0 asio00/0/5/0 asio00/1 lba0/2 lba0/2/0/0 c7200/2/0/0.0 tgt0/2/0/0.0.0 schgr0/2/0/0.1 tgt0/2/0/0.1.0 stape0/2/0/0.7 tgt0/2/0/0.7.0 sctl0/3 lba0/4 lbac8xx BUS: 5 SCSI C1010 Ultra Wide LVD assigned CPU: 00/4/0/0 c8xx0/4/0/0.6 tgt0/4/0/0.6.0 sctl0/5 lba0/5/0/0 c7200/5/0/0.2 tgt0/5/0/0.2.0 stape0/5/0/0.7 tgt0/5/0/0.7.0 sctl0/6 lba0/6/0/0 tdtd: claimed Tachyon XL2 Fibre Channel Mass Storage card at 0/6/0/00/6/0/0.8 fcp0/6/0/10.0 fcparray0/6/0/10.0.0 tgt0/6/0/ sdisk0/6/0/ sdisk0/6/0/ sdisk0/6/0/10.1 fcparray0/6/0/10.1.0 tg
