When configuring a system using Fibre Channels, you need to consider the following restrictions. For details about Fibre Channels, see the Provisioning Guide.
- When you use Fibre Channel as an external path, if you specify Auto for Port Speed, specify 10 seconds or more for Blocked Path Monitoring. If you want to specify 9 seconds or less, do not set Auto for Port Speed.
- If the time specified for Blocked Path Monitoring is not long enough, the network speed might be slowed down or the period for speed negotiation might be exceeded. As a result, paths might be blocked.
- If you set the operation mode of a port to NVMe mode to use NVMe over FC communication, you cannot use that port for an external path.
