SAN PIN Groups - Will they affect current server profiles already running?

[finnzi]

Hi all,

Due to some requirements I have to create 2 vHBAs per SAN fabric. Each FI in this setup has two uplinks to a SAN Fabric.

Currently there are 7 blades running with a single vHBA per Fabric (and are just balanced between the two uplinks).

If I create two pin groups per Fabric (one for each uplink) - will that affect the currently running servers or are the uplinks also available for dynamic assignment, even if they are in a pin group?

Bgrds,

Finnur

The pinning group policy is a policy that is actually applied to the vHBA in a service profile.

When you define the pinning group/policy, it's not actually applied to anything, so it will not modify your existing connections/service profiles, until you reference the san pinning group on a vHBA within a service profile, service profile template, san connectivity policy, etc.

Existing service profiles with vHBAs without san pinning group references, will continue to use and share the same uplink ports with dynamic pinning.

Brilliant - thanks for the answer!
