Soc+ Host Adapter Card Test (socaltest)

socaltest aids the validation and fault isolation of the SOC+ host adapter card. In the case of a faulty card, the test tries to isolate the fault to the card, the GBIC module, or the DMA between the host adapter card and the host memory.

TABLE 33-1 socaltest

socaltest Options	Description
Internal Loopback Test	Checks the host adapter card and the direct memory access (DMA) with the host system. This is accomplished as follows: · A frame is created in the host adapter local memory, sent out through the SOC+ transmitter and internally looped back to the SOC+ receiver. The received data is compared with the original data. · A frame is created in the host adapter local memory, sent out through the SOC+ transmitter and looped back through the SERDES (serialiser-deserialiser) chip on the host adapter card. The received data is compared with the original data. · A frame is created in the host main memory, transferred through the DMA to the host adapter transmitter, looped back within the SOC+ chip, and transferred from the receiver to the host main memory through the DMA. The received frame is compared with the original transmitted frame, which tests the host memory to the host adapter DMA path.
External Loopback Test	The External Loopback Test verifies the proper functioning of the GBIC module. A frame is created in the host adapter local memory, sent out and looped back through the external loopback connector attached to the port. If the external loopback test is run together with the internal loopback test, the DMA path is also tested by creating a frame in host main memory, transferring it to the host adapter through the DMA, looping it back through the external loopback connector and transferring the received frame back to the host main memory by DMA.
Loopback Frame Test	Sends out a buffer initialized with the selected pattern and compares it with the looped back frame. It passes if the two compare and fails if they do not.
Loopback Frame Pattern	List of selectable patterns for the Loopback Frame Test.

---

Note - In addition to the tests described above, socaltest also tests the basic functions of the SOC+ chip, the on-board XRAM, and the host control buffer by invoking the appropriate tests implemented in firmware.

---

socaltest Test Modes

socaltest can only be run in the Functional Test modes.

---

Note - You cannot run the internal and external loopback tests if the port is connected to a disk array.
