V-5-1-15206: DMP support for LVM bootability is disabled.

Problem

DMP (Dynamic Multipathing) Native support fails to get enabled after reboot on Infoscale 7.4 & 7.4.1 Over AIX Platform.
 

Error Message

# vxdmpadm native enable vgname=rootvg
Please reboot the system to enable DMP support for LVM bootability

** After Reboot of the system

# vxdmpadm native list 
VxVM vxdmpadm ERROR V-5-1-15206 DMP support for LVM bootability is disabled.
 

Cause

VxVM (Veritas Volume Manager) has a binary i.e vxdmpboot which runs at boot time to enable DMP Native Support for Root FileSystem.

The binary executes at a very early stage in the boot phase on the AIX platform and performs some licensing checks during execution. Earlier, the licensing specific library used to be a static library, but now it has been changed to Dynamic library.

At the boot time when the vxdmpboot binary is executed, most of the file systems are not mounted. The directory containing the Dynamic library is also not mounted and hence the library will not be available at boot time when the vxdmpboot binary is executed causing the failure in the licensing checks and failure of vxdmpboot execution. This failure prevents native support from getting enabled at boot time for Root Filesystem.
 

Solution

Licensing checks as part of vxdmpboot binary have been disabled to enable DMP native support successfully for root filesystem.
