The error message "V-78-58645-270: Operation failed. The disk cannot be added as a member of a cluster dynamic disk group because it is not on the shared bus" is returned while creating a cluster disk group in Veritas Storage Foundation (tm) for Windows
Exact Error Message
V-78-58645-270: Operation failed. The disk cannot be added as a member of a cluster dynamic disk group because it is not on the shared bus

Details:
***Note******************************************************
You may receive a similar error message of:
"V-39-58645-525 The disk can not be imported as a member of a cluster disk group because it is not on a shared bus."
of which the solution below is also the same solution.
****************************************************************
This error will occur if Storage Foundation detects that the system disk is sharing the same port as one of the disks to be imported into the cluster disk group.

To resolve this issue, follow these steps:

1. Open a command prompt

2. Type vxclus usesystembus ON and hit Enter. The following message will appear:

"V-77-57616-50026: WARNING: By enabling UseSystemBus you are going to create
cluster diskgroup on the disks which are connected to System/
Boot bus. Do you want to continue(Y/N)?"

3. Type y and hit Enter. The following message will appear:

"V-77-57616-4046: [hostname] Enabled UseSystemBus support."

These steps will need to be performed on all nodes in the cluster. It is now possible to create a cluster disk group without receiving the error.
