Re: How to check whether the multipathing is available or not?

Hi:

At 11.23 under LVM, you have "alternate links" otherwise known as 'pvlinks'. However, this is a high-availability feature, not a load-balancing one. In 11.31 the mass storage stack subsystem has been revamped and dynamic load-balancing between paths to a physical disk occurs.

You can see any alternate links that are configured by doing a 'vgdisplay -v vgname'. With LVM you use 'vgextend' to add and 'vgreduce' to remove alternate paths.

Regards!
