CAM - How to Remove and Replace Midrange Disk Impending Disk Failure:ATR:1311776.1:0 (文档 ID 1311776.1)

CAM 软件中如何移除和替换潜在故障的磁盘

1. Verify HDD status.

1.确认HDD状态.

a) If the HDD is a HOT SPARE, the administrator will need to UNASSIGN it before proceeding. Failure to do so may result in an alarm of "Missing Hot Spare Drive". Please consult DOCUMENT 1450121.1 if this occurs.

a)如果要更换的磁盘是热备盘，管理员需要在更换前手动取消热备盘。这可能会产生一个热备盘丢失的报错。

b) If the HDD is in a single-disk RAID 0 then delete the volume and vDisk before the disk is replaced. Please consult DOCUMENT 1345746.1 for issues with missing volumes if they are not deleted before the disk replacement.

b)如果要更换的磁盘是RAID0 ， 在更换磁盘前需要先是删除逻辑卷。

If the HDD is unassigned, continue to Step 3.

如果磁盘是未分配的，那么直接进行步骤3吧。

2. Use CAM, to verify the alarms on the array.If there is already a Degraded Volume and/or Hot Spare in Use fault for the HDD then continue to Step 3.

登录到CAM，如果卷组已经降级或热备盘已经顶替了损坏的磁盘，直接看3 。

WARNING : FOR RAID 0, if the faults are "Impending Failure Risk High", the replacement of the HDD will cause data loss. The volumes impacted by this fault should be removed from server access in preparation for this.

The HDD must be manually failed prior to replacement. Click on the Array->Physical Devices->Disks->Click on the Disk->Click Fail Button

磁盘必须手动标记为Fail（管理界面里中文是停用）才能进行更换步骤。 路径为 Array->Physical Devices->Disks->Click on the Disk->Click Fail Button

3. Use the Service Advisor(SA) for the Array in question to review HDD replacement directions. This will also show you how to toggle the HDD location indicator for replacement. Use the indicator to locate the HDD in question. The HDD should also be failed/faulted in the SA. If it is not contact the TSC or verify the reason for the HDD replacement yourself.

3.使用磁盘阵列的服务顾问查看磁盘更换指南，将会有一系列的步骤只是你如何操作，如果磁盘的状态还不是已损坏的状态的话，联系TSC或者自己确认原因。

4. The HDD location specified should be indicated by an amber fault LED for that Tray and Slot, as well as the white location LED if available on that tray.

坏盘黄色灯是亮起的，要确认。

5. Remove the HDD (wait 2 minutes in order to allow the array controllers to notice that the HDD has been removed), and then verify that the replacement HDD is the same:

5.移除坏盘，等两分钟让储存机头识别出硬盘已经被拔出来了，期间确认新盘和旧盘的如下信息是否一致。类型容量和转速。

a) type: SAS/SATA/FC/SSD

b) size

c) RPM

NOTE: the HDD make and model do not have to be the same, only the type, size and RPM.

6. Replace the HDD according to the instructions in the SA.

6.按照服务顾问中的向导进行进公安更换。

NOTE: If the HDD firmware needs updating, the customer will have to schedule this at a later date, as a copy back is typically immediate.

OBTAIN CUSTOMER ACCEPTANCE WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
1. Verify with customer that the HDD is in an OK or Optimal state.

2. Verify with the customer that the VDisk is reconstructing(if RAID 1,3,5,6). If it is not, you may need to manually start the reconstruction.

3. Verify that all Alarms regarding HDDs bypassed, degraded HDD channel, and impending failures have been removed from the system

4. If the VDisk is a RAID 0, the customer will have to re-create the vDisk and volumes and then restore the data from backup.

最后确认状态，raid0 的话当然要重建或者从备份恢复了。
