Replacing pdisks on IBM Power Server

  1. 确认故障。

    查看系统是否有硬盘报错。

    lsdev –Cc pdisk
    lsdev -Cc hdisk
    errpt

    检查 raid 信息和 pdisk 状态。

    diag -> Task Selection -> RAID Array Manager -> IBM SAS Disk Array Manager -> List IBM SAS Disk Array configuration

  2. 确认故障硬盘槽位。

    diag -> Task Selection -> RAID Array Manager -> IBM SAS Disk Array Manager -> Diagnostics and Recovery Options -> SCSI and SCSI RAID Hot Plug Manager -> Identify a Device Attached to an SCSI Hot Swap Enclosure Device

    选择对应的硬盘,按 F7 确认硬盘所在的槽位(磁盘的黄灯在闪烁)。

  3. 硬盘更换。

    diag -> Task Selection -> RAID Array Manager -> IBM SASDisk Array Manager -> Diagnostics and Recovery Options -> SCSI and SCSI RAID Hot Plug Manager -> Replace/Remove a Device Attached to an SCSI Hot Swap Enclosure Device

    -> SCSI and SCSI RAID Hot Plug Manager -> Configure Added/Replaced Devices

    diag -> Task selection -> RAID Array Manager -> IBM SAS Disk Array Manager -> List IBM SAS Disk Array configuration

    可以看到 pdisk0 的状态是 Failed。

    lsdev –Cc pdisk 是可以看到 pdisk0 是 Available。

    对 RAID 进行重建。

    diag -> Task selection -> RAID Array Manager -> IBM SAS Disk Array Manager -> Reconstruct a IBM SAS Disk Array

    重建完毕后,确认 RAID 的状态为 Optimal,硬盘容量显示正常。

    容量显示异常的话,可以 cfgmgr -v 重新扫描一下硬件。
