Formatted disks being placed under VxVM control may be new or previously used outside VxVM. The set of disks can consist of all disks on the system, all disks on a controller, selected disks, or a combination of these.
Depending on the circumstances, all of the disks may not be processed in the same way.
When initializing multiple disks at one time, it is possible to exclude certain disks or certain controllers.
To exclude a device from the view of VxVM, select Prevent multipathing/Suppress devices from VxVM's view from the vxdiskadm main menu.
To initialize disks for VxVM use
Select disk devices to add: [<pattern-list>,all,list,q,?]
The pattern-list can be a single disk, or a series of disks. If pattern-list consists of multiple items, separate them using white space. For example, specify four disks as follows:
hdisk10 hdisk11 hdisk12 hdisk13
If you enter list at the prompt, the vxdiskadm program displays a list of the disks available to the system:
DEVICE DISK GROUP STATUS hdisk0 - - LVM hdisk1 - - LVM hdisk2 - - LVM hdisk3 mydg01 mydg online hdisk4 mydg03 mydg online hdisk5 mydg04 mydg online hdisk6 mydg05 mydg online hdisk7 mydg06 mydg online hdisk8 mydg07 mydg online hdisk9 mydg02 mydg online hdisk10 mydg08 mydg online hdisk11 - - online invalid hdisk12 - - online
The phrase online invalid in the STATUS line indicates that a disk has yet to be added or initialized for VxVM control. Disks that are listed as online with a disk name and disk group are already under VxVM control.
Enter the device name or pattern of the disks that you want to initialize at the prompt and press Return.
Here are the disks selected. Output format: [Device] list of device names Continue operation? [y,n,q,?] (default: y) y
You can choose to add these disks to an existing disk group, a new disk group, or you can leave these disks 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 disks available for future use, specify a disk group name of none. Which disk group [<group>,none,list,q,?]
There is no active disk group named disk group name. Create a new group named disk group name? [y,n,q,?] (default: y)y
You are then prompted to confirm whether the disk group should support the Cross-platform Data Sharing (CDS) feature:
Create the disk group as a CDS disk group? [y,n,q,?] (default: n)
If the new disk group may be moved between different operating system platforms, enter y. Otherwise, enter n.
Use default disk names for the disks? [y,n,q,?] (default: y) n
Add disks as spare disks for disk group name? [y,n,q,?] (default: n) n
Exclude disks from hot-relocation use? [y,n,q,?} (default: n) n
Add site tag to disks? [y,n,q,?] (default: n)
A site tag is usually applied to disk arrays or enclosures, and is not required unless you want to use the Remote Mirror feature.
If you enter y to choose to add a site tag, you are prompted to the site name at step 11.
The selected disks will be added to the disk group disk group name with default disk names. list of device names Continue with operation? [y,n,q,?] (default: y) y
The following disk(s): list of device names belong to enclosure(s): list of enclosure names Enter site tag for disks on enclosure enclosure name [<name>,q,?] site_name
The following disk device appears to contain a currently unmounted file system. list of enclosure names Are you sure you want to destroy these file systems [y,n,q,?] (default: n) y
vxdiskadm asks you to confirm that the devices are to be reinitialized before proceeding:
Reinitialize these devices? [y,n,q,?] (default: n) y VxVM INFO V-5-2-205 Initializing device device name.
Enter the desired format [cdsdisk,aixdisk,q,?] (default: cdsdisk)
Enter the format that is appropriate for your needs. In most cases, this is the default format, cdsdisk.
Enter desired private region length [<privlen>,q,?] (default: 65536)
vxdiskadm then proceeds to add the disks.
VxVM INFO V-5-2-88 Adding disk device device name to disk group disk group name with disk name disk name. . . .
Add or initialize other disks? [y,n,q,?] (default: n)
The default layout for disks can be changed.
