Chapter 8 Solving SAN Problems 111
If You’re Unable to Add a Storage Pool
There are some reserved names you can’t use to name a storage pool. If you enter one
of these names, the OK button in the storage pool sheet is disabled.
If Fibre Channel Performance Is Poorer Than Expected
Mismatched optical transceivers (GBICs) can cause Fibre Channel communication errors
and degrade SAN performance. To ensure good performance, use identical transceivers
(same manufacturer and model number) on both ends of your Fibre Channel cables.
