Step 3: Determining your FC-AL requirements

When you set up your cluster for mirroring, you should consider the following:

The type and number of FC-AL adapters you have in your system
Where the FC-AL adapters are located in your cluster.
Disk pool 0 volumes are cabled to FC-AL or dual Fibre Channel adapters located in filer slots 3 through 7, if available. Disk Pool 1 volumes are cabled to FC-AL or dual Fibre Channel adapters in filer slots 8 and 9. No single FC-AL should become a single point of failure.
If you are converting a cluster into a mirrored cluster, whether you need to add more FC-AL adapters to spread them across disk pools

To determine your FC-AL requirements, complete the following steps.

Step	Action
1	Determine how many disk pools you have for each filer. You should have no more than two disk pools per filer for the local and partner nodes.
2	Determine the number of FC-AL adapters you have and install any additional adapters you need. See the Field Service Guide for installation instructions.
