"VxVM vxdmpadm ERROR V-5-1-15690 Operation failed for one or more volume groups" appears when enabling, or disabling, DMP native support on Oracle Linux

Problem

Enabling Dynamic Multi-Pathing (DMP) native support on Oracle Linux 7.x may fail.

Error Message

VxVM vxdmpadm ERROR V-5-1-15690 Operation failed for one or more volume groups

Cause

The issue can happen if these conditions are true:

• There are multiple kernels present in the GRUB configuration file.
• The default kernel is not compatible with the Volume Manager component of InfoScale, for example: the Oracle Unbreakable Enterprise Kernel (UEK).

 

Solution

The following workaround can be used to address this issue:

1. Enable, or disable, DMP native support
2. Manually change the default kernel in GRUB to the Oracle Linux kernel that is supported by the Volume Manager component (i.e for OL 7.3).
3. Reboot the system.
