To initialize disks as VxVM disks

1. Scan for the new hdisk devices.

   # /usr/sbin/cfgmgr

2. List the new external disks or the LUNs as recognized by the operating system. On each node, enter:

   # lsdev -Cc disk

3. Determine the VxVM name by which a disk drive (or LUN) is known.

   In the following example, VxVM identifies a disk with the AIX device name /dev/rhdisk75 as EMC0_17:

   # vxdmpadm getdmpnode nodename=hdisk75
   NAME     STATE    ENCLR-TYPE   PATHS    ENBL    DSBL    ENCLR-NAME
   ============================================================
   EMC0_17  ENABLED  EMC          1        1       0       EMC0
   Notice that in the example command, the AIX device name for 
   the block device was used.

   As an option, you can run the command vxdisk list vxvm_device_name to see additional information about the disk like the AIX device name. For example:

   # vxdisk list EMC0_17

4. To initialize the disks as VxVM disks, use one of the following methods:

   • Use the interactive vxdiskadm utility to initialize the disks as VxVM disks.

     For more information, see the Storage Foundation Administrator's Guide.

   • Use the vxdisksetup command to initialize a disk as a VxVM disk.

     # vxdisksetup -i device_name

     The example specifies the CDS format:

       # vxdisksetup -i EMC0_17

     Repeat this command for each disk you intend to use as a coordinator disk.
