Raid10换盘.doc

（做的raid10）于是直接开始diag-task selection-ssa aids servie-set service mode，选择该pdisk27进行更换rmdev -dl pdisk27 ，然后插入新盘cfgmgr -vl ssar发现了新的pdisk27.确认下 lscfg -vl pdisk27看是不是sn和新的一样。smitty ssaraidChange/Show use of an ssa physical disk将新加硬盘的状态变为 Array Candidate.在再Swap Members of an SSA RAID Array将新盘加进去。最后 smitty lstssaraid 选raid10看到rebuilding的进度了。SSA卡的raid1/10实现的，可以用下面的步骤，完成换盘操作：首先errpt |more查看有没有硬件报错信息.1.#diag ?; Task Selection (Diagnostics, Advanced Diagnostics, Service Aids, etc.)?;SSA Service Aids?;Link Verification (确定失效的pdisk_xx;)2.#smitty ssaraid ?; Change Member Disks in an SSA RAID Array ?; Remove a Disk from SSA RAID Array ?;选择相关的hdisk_x ?;Disk Remove 用F4选择失效的pdisk_xx；3.#diag?; Task Selection (Diagnostics, Advanced Diagnostics, Service Aids, etc.)?;SSA Service Aids?; Set Service Mode?;把该盘设为service mode；(黄灯长亮)4.物理更换SSA硬盘；(绿灯长亮)5.执行#rmdev dl (bad_pdisk_xx)#cfgmgr v (可以识别到新增加的硬盘;)6.#smitty ssaraid ?; Change/show Use of an SSA Physical Disk选择ssa0?;把#SSA physical disks that are free#提示下的pdisk_xx的 Current Use属性从system disk改为Array Candidate Disk 再加到RAID Array（注意：若系统有定义了Hot Spare disk，则原来失败的disk自动由hot spare disk代替，则把新增加的disk改为hot spare disk）。7.#smitty ssaraid ?; Change Member Disks in an SSA RAID Array?; Add a Disk to an SSA RAID Array (这步操作没用,只能用Swap方式操作,请看下面提示)?;选择相关的hdisk -用F4选择新增加的pdisk_xx（注意：如果在add时没有可选的盘，则在Swap Members of an SSA RAID Array子菜单下进入操作）；8.#smitty lstssaraid?;选择raid type(raid_10)可以看到阵列中更换的pdisk_xx正在rebuilding
