SPARC: 如何移除 SCSI 设备

1. 确定当前的 SCSI 配置。

   # cfgadm -al

2. 从系统中移除 SCSI 设备。
   1. 键入以下命令。

      # cfgadm -x remove_device device

   2. 在提示符下键入 y 以继续操作。

      正在执行热插拔操作的同时，SCSI 总线上的 I/O 活动会暂停。

   3. 关闭要移除的设备的电源，然后将其移除。
   4. 确认操作是否已完成。

   注 -  如果是从 SCSI RAID 阵列中移除 SCSI RAID 设备，那么必须执行此步骤。

3. 验证是否已从系统中移除了设备。

   # cfgadm -al

Removing SCSI device: /devices/pci@7c0/pci@0/pci@1/pci@0,2/LSILogic,sas@2/sd@3,0
This operation will suspend activity on SCSI bus: c3
Continue (yes/no)? y
SCSI bus quiesced successfully.
It is now safe to proceed with hotplug operation.

关闭设备的电源并移除该设备后，将继续运行并显示提示。

Enter y if operation is complete or n to abort (yes/no)? y
