Hi Tony:

On 10.20, two (2) alternate links (pvlinks) per volume group are supported.

On 11.x, up to eight (8) links are allowed.

I've read 16.
And tested and verified 8.
Even in my case adding 8 was a bit silly as it covered cases of multiple simultaneous failures. It is best to keep it at 3 pvlinks per pv... simply for sake of management.

Your VG is limited to 16 real PVs by default.. but PVlinks are not included in this.

Later,
Bill
