FSS disk group creation fails for clusters with eight or more nodes that have several directly attached disks (3986110)
The creation of an FSS disk group or the addition of a disk to an existing FSS disk group fails and logs the following error:
VxVM vxdg ERROR V-5-1-10127 associating disk-media smicro101_exosx100_0 with smicro101_exosx100_0:
Slave failed to create remote disk
This issue occurs when a cluster has eight or more nodes and several directly attached disks. In case of such a configuration, a race condition occurs during operations like disk group creation or disk addition to an existing group. The race condition deletes the disk records from the kernel and consequently fails to add disks to a disk group.

Workaround:
In a cluster with eight or more nodes and several directly attached disks, create the disk group with a few disks at a time instead of with all the disks in one go.
