How to Create a Non-Root rootdg Disk Group

Use this procedure to create a rootdg disk group by encapsulating or initializing local non-root disks.

1. Have available the VERITAS Volume Manager (VxVM) license keys.

2. Become superuser on the node.

3. (Optional) If the disks will be encapsulated, ensure that each disk has at least two slices with 0 cylinders.

   If necessary, use the format(1M) command to assign 0 cylinders to each VxVM slice.

4. Start the vxinstall(1M) utility.

   # vxinstall

   When prompted, make the following choices or entries.

   • Choose Custom Installation.

   • Do not encapsulate the root disk.

   • Choose any disks you want added to the rootdg disk group.

   • Do not accept automatic reboot.

5. Evacuate any resource groups or device groups from the node.

   # scswitch -S -h node

   -S

   Evacuates all resource groups and device groups.

   -h node

   Specifies the name of the node from which to evacuate resource or device groups.

6. Reboot the node.

   # shutdown -g 0 -y -i 6
