FAS8020 storage initiator connection rules in a MetroCluster solution

Applies to

MetroCluster
ONTAP 9
FAS8020 only

Issue

In a MetroCluster in clustered Data ONTAP, each controller must have two HBA initiator connections to each of the two fabrics to connect storage. Along with that, each controller requires four HBA initiator ports.

When using FAS8020 controllers, there might be a need to only use two, instead of four, HBA initiator ports to connect storage to use the single free slot for host connectivity or tape backup. This applies to the FAS8020 only and no other platform. This type configuration can also be called as a 'single initiator per fabric' configuration.

Note : If a MetroCluster is configured using FAS8020 controllers and the hardware configuration is changed, these rules must be evaluated in order to add / remote paths so the configuration remains supported.

How to identify a mismatch of shortwave and longrange SFPs in a FC-VI card?

Applies to

MetroCluster FC
FCVI
long wave and short wave intermix

Description

SFPs need to be the same for both ports on the FCVI card. The below procedure explains how to identify a mismatch.
In order to decide on the correct type of SFP you need to verify the infrastructure (cables / patch pannels) used in the datacenter.
