exdata服务器下电和加电方案

1、Exdata服务器关机和开机方案Exadata关机步骤一 告警灯检查下电之前先检查EXdata主机的ib交换机、网管交换机、数据库服务器、存储服务器、PDU有没有黄灯告警二 系统健康状态检查1. infiniband交换机输入以下命令：versionibhostsshowunhealthyenv_testshowpsufru showtempsshowdiskdmesg2. 网管交换机检查#show running-config3. 存储服务器检查dcli g cell_group l root “ipmitool sunoem cli show faulty”dcli -g cell_gro

2、up -l root -r "reco" "cellcli -e list physicaldisk"dcli -g cell_group -l root -r "reco" "cellcli -e list physicaldisk attributes name,errmediacount where disktype=harddisk and errmediacount>0"dcli -g cell_group -l root -r "reco" "/opt/MegaRAI

3、D/MegaCli/MegaCli64 -Pdlist -a0 |grep 'Slot|Firmware state'"dcli -g cell_group -l root "cellcli -e list griddisk attributes name,asmmodestatus,asmdeactivationoutcome"dcli -g cell_group -l root -r "reco" "biosconfig -get_boot_order | grep DEVICE_NAME"4. 数据库服

4、务器检查dcli g cell_group l root “ipmitool sunoem cli show faulty”dcli -g all_group -l root "/opt/MegaRAID/MegaCli/MegaCli64 -LdInfo -lAll -aAll"dcli -g all_group -l root "/opt/MegaRAID/MegaCli/MegaCli64 -Pdlist -a0 |grep 'Slot|Firmware state'"5. PDU检查登陆到PDU web页面截图三 下电操作1. 关

5、闭数据库节点的集群和数据库首先停止所有数据库节点的CRS使用如下命令：#dcli - g dbs_group -l root “/u01/app/11.2.0.3/grid/bin/crsctl stop crs”注：如果命令执行失败可在命令行末尾加参数 -f 强制关闭CRS2. 在命令执行完毕后执行如下命令验证是否所有节点的crs服务都已经停止,如果无输出就说明所有crs都已停止#dcli -g dbs_group -l root ps -ef |grep d.bin |grep -v grep 3. 停止存储服务器上的cell服务#dcli -g cell_group -l root ”c

6、ellcli -e alter cell shutdown services all”或者#dcli -g cell_group -l root /etc/init.d/celld stop 4. 关闭存储节点的主机#dcli -g cell_group -l root shutdown -h -y now 5. 关闭数据库节点的主机#dcli -g dbs_group shutdown -h -y now6. 手动关闭机柜PDU-A和PDU-B的开关到OFF状态Exadata开机步骤一 确认所需更换的备件已更换完毕，服务器安放回原机柜位置，各种线缆和原安插位置一致二 服务器加电 手动将PDU

7、-A和PDU-B的电源开关调制ON 状态三 按启动开关手动启动节点主机1. 确定infiniband 和cisco交换机完全启动2. 先给cell节点加电开机，系统正常启动-见图23. 然后再给db节点加电开机-见图1 图1图2四 告警灯检查检查EXdata主机的ib交换机、网管交换机、数据库服务器、存储服务器、PDU有没有黄灯告警五 系统健康检查1.重启完成后，cell服务会自动启动，使用如下命令确认cell服务已正常启动#dcli -g cell_group -l root /etc/init.d/celld status2.确认CRS是否正常启动，命令如下：#dcli -g dbs_gr

8、oup -l root /u01/app/11.2.0.3/grid/bin/crsctl stat res -t1.infiniband交换机输入以下命令：versionnm2versionibhostsshowunhealthyenv_testshowfruinfoshowpsufru showtempsshowdiskshowfreeshowsmlogshowtopology2. 网管交换机检查#show running-config3.存储服务器检查dcli -g cell_group -l root -r "reco" "cellcli -e list
