目的

更换磁盘后恢复磁盘盘符
磁盘已完成替换

现象

磁盘设备

可以看到， sdb 设备已经不存在

# ls  /dev/sd?
/dev/sda  /dev/sdc  /dev/sdd  /dev/sde  /dev/sdf  /dev/sdg

尝试创建磁盘失败

# megacli -CfgLdAdd -r0 [0:2]  WB Direct -a0
Adapter 0: Configure Adapter Failed
zW error description:
 The current operation is not allowed because the controller has data in cache for offline or missing virtual disks.
Exit Code: 0x54

原因, 磁盘之前已创建了虚拟设备

查询虚拟设备

# megacli -LDInfo -LALL –aAll | grep Virtual
Adapter 0 -- Virtual Drive Information:
Virtual Drive: 0 (Target Id: 0)
Virtual Drive: 2 (Target Id: 2)
Virtual Drive: 3 (Target Id: 3)
Virtual Drive: 4 (Target Id: 4)
Virtual Drive: 5 (Target Id: 5)
Virtual Drive: 6 (Target Id: 6)

查询虚拟设备磁盘关系

# megacli -LDInfo -LALL -aAll  | grep -E "Virtual|Raid\ Level|Mirror|Number|^Size"
Adapter 0 -- Virtual Drive Information:
Virtual Drive: 0 (Target Id: 0)
Size                : 3.637 TB
Mirror Data         : 3.637 TB
Number Of Drives    : 2
Virtual Drive: 2 (Target Id: 2)
Size                : 3.637 TB
Number Of Drives    : 1
Virtual Drive: 3 (Target Id: 3)
Size                : 3.637 TB
Number Of Drives    : 1
Virtual Drive: 4 (Target Id: 4)
Size                : 3.637 TB
Number Of Drives    : 1
Virtual Drive: 5 (Target Id: 5)
Size                : 3.637 TB
Number Of Drives    : 1
Virtual Drive: 6 (Target Id: 6)
Size                : 3.637 TB
Number Of Drives    : 1

很明显， Virtual Drive: 1 就是之前替换的磁盘

# megacli -PDList -a0  | grep -E "Slot|DiskGroup"
Slot Number: 0
Drive's postion: DiskGroup: 0, Span: 0, Arm: 0
Slot Number: 1
Drive's postion: DiskGroup: 0, Span: 0, Arm: 1
Slot Number: 2
Slot Number: 3
Drive's postion: DiskGroup: 1, Span: 0, Arm: 0
Slot Number: 4
Drive's postion: DiskGroup: 2, Span: 0, Arm: 0
Slot Number: 5
Drive's postion: DiskGroup: 3, Span: 0, Arm: 0
Slot Number: 6
Drive's postion: DiskGroup: 4, Span: 0, Arm: 0
Slot Number: 7
Drive's postion: DiskGroup: 5, Span: 0, Arm: 0

清理一下缓存

# megacli -DiscardPreservedCache -L1 -a0
Adapter #0
Virtual Drive(Target ID 01): Preserved Cache Data Cleared.    <- 这里就把 磁盘缓存给清理掉了
Exit Code: 0x00

重建 raid0

# megacli -CfgLdAdd -r0 [0:2] WB Direct -a0
Adapter 0: Created VD 1
Adapter 0: Configured the Adapter!!
Exit Code: 0x00

使用磁盘

(sdb 回来了)

# ls /dev/sd?
/dev/sda  /dev/sdb  /dev/sdc  /dev/sdd  /dev/sde  /dev/sdf  /dev/sdg

分区格式化

# parted -s /dev/sdb  mklabel gpt
]# parted /dev/sdb  mkpart primary xfs 1 100%
Information: You may need to update /etc/fstab.
# mkfs -t xfs -i size=1024 /dev/sdb1
