 Replace a failed or removed disk

 Menu: VolumeManager/Disk/ReplaceDisk

 

  Use this menu operation to specify a replacement disk for a disk

  that you removed with the "Remove a disk for replacement" menu

  operation, or that failed during use.  You will be prompted for

  a disk name to replace and a disk device to use as a replacement.

  You can choose an uninitialized disk, in which case the disk will

  be initialized, or you can choose a disk that you have already

  initialized using the Add or initialize a disk menu operation.

 

 Select a removed or failed disk [,list,q,?] list

 Select disk device to initialize [

,list,q,?] c1t3d0

 

  The following disk device has a valid VTOC, but does not appear to have

  been initialized for the Volume Manager.  If there is data on the disk

  that should NOT be destroyed you should encapsulate the existing disk

  partitions as volumes instead of adding the disk as a new disk.

  Output format: [Device_Name]

 

  c1t3d0

 

 Encapsulate this device? [y,n,q,?] (default: y) n

 

  c1t3d0

 

 Instead of encapsulating, initialize? [y,n,q,?] (default: n) y

 

  The requested operation is to initialize disk device c1t3d0 and

  to then use that device to replace the removed or failed disk

  c1t3d0 in disk group rootdg.

 

 Continue with operation? [y,n,q,?] (default: y) y

 

 Use fastresync for plex synchronization? [y,n,q,?] (default: n) y

 

 Use a default private region length for the disk?

 [y,n,q,?] (default: y)

 

  Replacement of disk c1t3d0 in group rootdg with disk device

  c1t3d0 completed successfully.

 

 Replace another disk? [y,n,q,?] (default: n)

 root@ser2 # vxprint -ht 可以查看到这两个磁盘上建了两个逻辑卷，这两个磁盘之间做的是镜像：

 

 v  lvmmsc       -            ENABLED  ACTIVE   71303168 SELECT    -        fsgen

 pl lvmmsc-01    lvmmsc       ENABLED  ACTIVE   71303232 CONCAT    -        RW

 sd c1t3d0-02    lvmmsc-02    c1t3d0   71303232 71303232 0         c1t3d0   RLOC

 

 v  lvoracle     -            ENABLED  ACTIVE   71303168 SELECT    -        fsgen

 sd c1t3d0-01    lvoracle-02  c1t3d0   0        71303232 0         c1t3d0   ENA

 

 但是这两个卷中c1t3d0对应的pl的状态在换完磁盘后状态不正常（ENABLED  STALE），正常状态应该是：ENABLED  ACTIVE的，所以需要修复，修复命令如下：

 # vxmend -g rootdg clear all lvmmsc lvmmsc-02

 # vxplex -g rootdg dis lvmmsc-02

 # vxplex -g rootdg att lvmmsc lvmmsc-02

 

 # vxmend -g rootdg clear all lvoracle lvoracle-02

 # vxplex -g rootdg dis lvoracle-02

 # vxplex -g rootdg att lvoracle lvoracle-02

 

 修复完后用vxtask list查看后台同步信息!

 

还有一个方法：

 

root@ser2 # vxdiskadm ->4 Remove a disk for replacement

 root@ser2 # vxdisk offline c1t3d0s2

 root@ser2 # cfgadm –c unconfigure c1::dsk/c1t3d0

 

 硬盘蓝灯亮，更换硬盘

 root@ser2 # cfgadm –c configure c1::dsk/c1t3d0

 root@ser2 # /usr/sbin/devfsadm -C -c disk

 root@ser2 # devfsadm (执行后format命令显示正常)

 root@ser2 # vxdctl enable

 root@ser2 # vxdiskadm ->5 Replace a failed or removed disk
