Display help about menu ?? Display help about the menuing system q Exit from menus 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,?] 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 [

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 -

 

 

 

 

 

 

 

这一步骤需要在master节点上进行

# vxdg deport oradg # vxdg -s import oradg # vxdg list NAME STATE ID oradg enabled,shared,cds 1094209675.12.cluster2 #

 

 

 

 

3.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 #
