The disks should be discovered by OS before it can be added to Veritas Volume Manager.
1. List the disks detected by VxVM.
# vxdisk -o alldgs list
Eg :
[root@rhel61 ~]# vxdisk -o alldgs list
DEVICE TYPE DISK GROUP STATUS
sda auto:none - - online invalid
sdb auto:none - - online invalid
sdc auto:cdsdisk mydg01 mydg online
sdd auto:cdsdisk mydg02 mydg online
[root@rhel61 ~]#
sda and sbd are not configured / initialized for VxVM; where as sdc and sdd are initialized and added to a disk group.
2. Initialize disks.
vxdisksetup -i [attributes]
# vxdisksetup -i sdc
# vxdisksetup -i emc0_dd1
Initializing a disk will create Privae and Public regions in the disks, Meta data is stored in private region and public reagion is available for general purpose data usage. 32 MB is reserved for private region.
