Before adding the disk,

take an output from the format command.

take an output of vxdisk list

after the disk is added, do the following:

#devfsadm

#format --> label the disk

#vxdctl enable

#vxdiskadm choose the option 1 and then it will ask you the
diskgroup once it has been added it will ask for the
encapsulation, say no then it will ask the device name,
assign the name, that's it,

#vxdisk list, this will tell the status of the newly added
disk as online
