EMC损坏硬盘更换及恢复过程

更换EMC损坏的磁盘以后,盘阵会自动开始把hot spare备份的数据恢复过来。
然后把启用的hot spare盘恢复到初始备用状态。

我们可以通过命令来观察这一过程,首先看新换上来的硬盘,注意此时的状态为Equalizing,也就是正在进行平衡的过程:
# navicli -h 172.16.9.5 getdisk 1_0_1
Bus 1 Enclosure 0  Disk 1
Vendor Id:               SEAGATE

此时hot spare盘的状态为Enabled,其替代的硬盘为:1_0_1
# navicli -h 172.16.9.5 getdisk 1_0_14
Bus 1 Enclosure 0  Disk 14
Vendor Id:               SEAGATE 
Product Id:              ST314680 CLAR72 
Product Revision:        7A0A
Lun:                     102 
Type:                    102: Hot Spare 
State:                   Enabled
Hot Spare:               102: YES 
Hot Spare Replacing:     1_0_1
....

当重算完成以后,1_0_1的状态变为Enabled
# navicli -h 172.16.9.5 getdisk 1_0_1
Bus 1 Enclosure 0  Disk 1
Vendor Id:               SEAGATE 
Product Id:              ST373307 CLAR72 
Product Revision:        7A0A
Lun:                     6 
Type:                    6: RAID5 
State:                   Enabled
Hot Spare:               6: NO 
......

而此时的hot spare盘状态重新变为:Hot Spare Ready,至此恢复过程彻底完成。
# navicli -h 172.16.9.5 getdisk 1_0_14
Bus 1 Enclosure 0  Disk 14
Vendor Id:               SEAGATE 
Product Id:              ST314680 CLAR72

Lun:                     102 
Type:                    102: Hot Spare 
State:                   Hot Spare Ready
Hot Spare:               102: YES 
Hot Spare Replacing:     Inactive
....

没有使用过EMC的阵列,
不过还是开了眼界

我这的CX400现在坏了第一块盘,但是上面说0-3块盘上装了阵列软件,如果拔掉或移动这几块盘的话阵列会用不了,该怎么办呢?

那三块盘做的是Raid5啊,当然可以换了,你怕什么。
