Physical and Logical Devices
The SOL subsystem consists of several physical and logical devices in the ODM configuration database.
| Device | Description |
|---|---|
| slc (serial link chip) | There are two serial link adapters in each COMBO chip. The slc device is automatically detected and configured by the system. |
| otp (optic two-port card) | Also known as the serial optical channel converter (SOCC). There is one SOCC possible for each slc. The otp device is automatically detected and configured by the system. |
| op (optic port) | There are two optic ports per otp. The op device is automatically detected and configured by the system. |
| ops (optic port subsystem) | This is a logical device. There is only one created at any time. The ops device requires some additional configuration initially, and is then automatically configured from that point on. The /dev/ops0 special file is created when the ops device is configured. The ops device cannot be configured when the processor ID is set to -1. |
