7133 D40更换硬盘（方案+实战）

IBM 7133磁盘阵列硬盘更换操作： A.检查7133磁盘阵列连接的SSA环路中每台RS6000小型机的errpt及mail中报错信息,记录报错pdisk及SRN等信息;检查每台小型机报错后,下列步骤在其中一台小型机上完成,如该array在使用的小型机; B.通过smitty ssaraid命令,进入SSA的专用操作菜单,检查阵列当前array状态,是否有array degraded,是否有hot spare盘被使用; C.检查报错的硬盘所在array对应hdisk,确定所在array raid类型; D.lspv检查确定有硬盘故障hdisk所在vg,lsvg –l *vg检查当前vg内lv是否都是syncd; E.根据阵列状态及报错确定故障pdisk后,lscfg –vl pdisk*检查该pdisk VPD信息,确认FRU,SN等信息供IBM工程师订新备件; F.如果该array中故障pdisk已经failed,则直接跳到H;如果该array中报错的pdisk仍在使用,则进行下一步; G.通过smitty ssaraid命令进入菜单,选择 Change Member Disks in an SSA RAID Array Remove a Disk From an SSA RAID Array 从array中移除报错的pdisk,这时array状态会变成degreded; H.通过diag命令进入菜单,选择 Task selection->SSA->set service mode 选中报错的pdisk并设置service mode; I.根据7133存储上亮起的黄色指示灯确认故障硬盘位置,平稳拔出硬盘,等待5s,平稳插入新硬盘; J.在该7133 SSA Link中每台IBM小型机上,执行rmdev –dl pdisk*删除故障pdisk信息(注意每台小型机上pdisk并不一至),并cfgmgr重认设备,检查发现新硬盘,lscfg –vl pdisk*检查新硬盘信息正常; K.通过smitty ssaraid菜单,选择 Change/Show Use of an SSA Physical Disk 若hot spare在使用中则将新pdisk设置成hot spare,跳到步骤M; 若无hot spare则将新pdisk设置成array candidate,继续下一步; L.在array无hot spare情况下,这时需要将新pdisk加入degraded状态的array,在SSA菜单中选择 Change Member Disks in an SSA RAID Array Swap Members of an SSA RAID Array 菜单中分别选择:故障所在array,被剔出pdisk留下的blank信息,新pdisk;执行后新pdisk就加入该array并开始同步阵列; M.同步开始后, 重新在SSA菜单中检查SSA Link中每台IBM小型机以下内容 List All Defined SSA RAID Arrays List Status Of All Defined SSA RAID Arrays 确认array rebuilding状态,及完成进度; N.重新检查每台小型机errpt,mail及diag中ssa link status等无异常,其中errpt中有更换磁盘时的ssa open link等报错属正常现象; O.耐心等待array同步完成显示good状态,所有工作完成. 实战操作过程：（1）故障信息,7133连接12块73.4G磁盘,所有磁盘状态灯亮绿灯，连接的两台主机上有报错，初步诊断是硬盘或者是SSA卡有问题。 IBM,7028-6C4 --------------------------------------------------------------------------- LABEL: SSA_DEVICE_ERROR IDENTIFIER: FE9E9357 Date/Time: Fri Sep 18 00:00:00 beij Sequence Number: 43354 Machine Id: 0001C79E4C00 Node Id: BJBJ_BS_USSD_SV02 Class: H Type: PERM Resource Name: ssa0 Resource Class: adapter Resource Type: ssa160 Location: 1H-08 VPD: Part Number................. 27H1204 FRU Number.................. 34L5388 Serial Number...............S3352180 EC Level....................
