Need a way to silently create a diskgroup

[jm6601]

I'm looking for the commands to silently create a diskgroup.  I've tried passing the answers the vxdiskadd but that does not work well.

**********************************
EXAMPLE OF MANUAL INPUT TO vxdiskadd
**********************************
11:34:42 # vxdiskadd sda

Add or initialize disks
Menu:: VolumeManager/Disk/AddDisks

Here is the disk selected. Output format: [Device_Name]

sda

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

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

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

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

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

Exclude disk from hot-relocation use? [y,n,q,?] (default: n) n

Add site tag to disk? [y,n,q,?] (default: n) n

A new disk group will be created named dgGate and the selected disks
will be added to the disk group with default disk names.

sda

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

Initializing device sda.

Enter desired private region length
[<privlen>,q,?] (default: 65536) 65536

VxVM NOTICE V-5-2-120
Creating a new disk group named dgGate containing the disk
device sda with the name dgGate01.

Goodbye.

 Try this one, vxdg init dgGate sda 

good luck.

I tried vxdg init, but received an error.  I did not write down the error and my putty buffer is full.  The fix was to execute '/etc/vx/bin/vxdisksetup -i <disk>'.  I did a little research and vxdiskadd performs the work for vxdisksetup.  What else does vxdiskadd do that needs to be added?

Hello,

Well process goes like this:

a) you need to initialize a disk (using vxdiskadd or vxdisksetup, both will be calling a lower command called vxdisk), ultimate goal of this command is to create a public & private region on the disk.

b) once public & private regions are created, vxdiskadd adds the disk to the diskgroup...

So, ideally for a new disk following should be shortest steps:

a) vxdisksetup -i sdx
b) vxdg init <diskgroup> xxx=sdx

where xxx is the name you want to call for disks...
