# vxdiskadm 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 4 Remove a disk for replacement 5 Replace a failed or removed disk 6 Mirror volumes on a disk 7 Move volumes from a disk 8 Enable access to (import) a disk group 9 Remove access to (deport) a disk group 10 Enable (online) a disk device 11 Disable (offline) a disk device 12 Mark a disk as a spare for a disk group 13 Turn off the spare flag on a disk 14 Unrelocate subdisks back to a disk 15 Exclude a disk from hot-relocation use 16 Make a disk available for hot-relocation use 17 Prevent multipathing/Suppress devices from VxVM's view 18 Allow multipathing/Unsuppress devices from VxVM's view 19 List currently suppressed/non-multipathed devices 20 Change the disk naming scheme 21 Get the newly connected/zoned disks in VxVM view 22 Change/Display the default disk layouts 23 Mark a disk as allocator-reserved for a disk group 24 Turn off the allocator-reserved flag on a disk list List disk information ? 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: [<pattern-list>,all,list,q,?] list DEVICE DISK GROUP STATUS c0t0d0 - - online invalid c0t1d0 - - online invalid c2t0d2 - - online Select disk devices to add: [<pattern-list>,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 [<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 [<privlen>,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.

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 #
