Select an operation to perform: 1



Add or initialize disks
Menu: VolumeManager/Disk/AddDisks
  Use this operation to add one or more disks to a disk group.  You can
  add the selected disks to an existing disk group or to a new disk group
  that will be created as a part of the operation. The selected disks may
  also be added to a disk group as spares. Or they may be added as
  nohotuses to be excluded from hot-relocation use. The selected
  disks may also be initialized without adding them to a disk group 
  leaving the disks available for use as replacement disks.

  More than one disk or pattern may be entered at the prompt.  Here are
  some disk selection examples:

  all:          all disks
  c3 c4t2:      all disks on both controller 3 and controller 4, target 2
  c3t4d2:       a single disk (in the c#t#d# naming scheme)
  xyz_0 :       a single disk (in the enclosure based naming scheme)
  xyz_ :        all disks on the enclosure whose name is xyz

Select disk devices to add: [,all,list,q,?] list

DEVICE       DISK         GROUP        STATUS
c0t0d0       -            -            online invalid
c0t1d0       -            -            online invalid
c2t0d2       -            -            online

Select disk devices to add: [,all,list,q,?] c2t0d2
  Here is the disk selected.  Output format: [Device_Name]

  c2t0d2

Continue operation? [y,n,q,?] (default: y) 
  You can choose to add this disk to an existing disk group, a
  new disk group, or leave the disk available for use by future
  add or replacement operations.  To create a new disk group,
  select a disk group name that does not yet exist.  To leave
  the disk available for future use, specify a disk group name
  of "none".

Which disk group [,none,list,q,?] (default: 9iRac) oradg
  There is no active disk group named oradg.

Create a new group named oradg? [y,n,q,?] (default: y) 

Create the disk group as a CDS disk group? [y,n,q,?] (default: y) 

Use a default disk name for the disk? [y,n,q,?] (default: y) 

Add disk as a spare disk for oradg? [y,n,q,?] (default: n) 

Exclude disk from hot-relocation use? [y,n,q,?] (default: n) 
  A new disk group will be created named oradg and the selected disks
  will be added to the disk group with default disk names.

  c2t0d2

Continue with operation? [y,n,q,?] (default: y) 
  The following disk device appears to have been initialized already.
  The disk is currently available as a replacement disk.
  Output format: [Device_Name]

  c2t0d2

Use this device? [y,n,q,?] (default: y) 
  The following disk you selected for use appears to already have
  been initialized for the Volume Manager.  If you are certain the
  disk has already been initialized for the Volume Manager, then you
  do not need to reinitialize the disk device.
  Output format: [Device_Name]

  c2t0d2

Reinitialize this device? [y,n,q,?] (default: y) 
  Initializing device c2t0d2.

Enter desired private region length
[,q,?] (default: 2048) 
  VxVM  NOTICE V-5-2-120
Creating a new disk group named oradg containing the disk
  device c2t0d2 with the name oradg01.

Add or initialize other disks? [y,n,q,?] (default: n) 


Volume Manager Support Operations
Menu: VolumeManager/Disk

 1      Add or initialize one or more disks
 2      Encapsulate one or more disks
 3      Remove a disk

Goodbye.

2.设置共享磁盘组

# vxdg list
NAME STATE ID
oradg enabled,cds 1094209675.12.cluster2
# vxdg free
GROUP DISK DEVICE TAG OFFSET LENGTH FLAGS
oradg oradg01 c2t0d2s2 c2t0d2 0 244143872 -

 

3.通过以下方式验证主节点:

 
# vxclustadm -v nodestate
state: cluster member
        nodeId=1
        masterId=1 --这就是主节点id
        neighborId=0
        members=0x3
        joiners=0x0
        leavers=0x0
        reconfig_seqnum=0x2a9209
        vxfen=off
# fsclustadm idtoname 1
cluster1

或者使用:
# vxdctl -c mode
mode: enabled: cluster active - SLAVE
master: cluster1  

如果你的输出出现以下提示:

# ./vxclustadm -v nodestate
state: out of cluster

 

这说明你没有正确配置IO Fencing.我们可以通过如下方式禁用IO Fencing.

创建/etc/vxfenmode 文件

增加一行:

vxfen_mode=disabled

重起Cluster既可.

4.在master节点上进行以下操作

# vxdg deport oradg
# vxdg -s import oradg
# vxdg list
NAME         STATE           ID
oradg        enabled,shared,cds   1094209675.12.cluster2
#
 
5.此时在另外节点上

应该可以看到此共享磁盘组

# vxdg list
NAME         STATE           ID
oradg        enabled,shared,cds   1094209675.12.cluster2
# hostname
cluster1
#
