Restoring an SP Boot Image

This procedure describes recovering the SP boot image for a storage processor in an SSR212PP-Series storage system.

Follow this procedure if an SP hangs during startup and cannot boot. An SP indicates that it is trying to boot by flashing the amber light on its back panel four times a second. If it cannot boot, it continues flashing the light four times each second or remains steadily on.

Normally, you can recover an SP s boot image using the steps in this section. But if no valid SP boot image exists on your storage system, you need to use FTP to load one. See Procedure 33, "Using FTP to Obtain and Store an SP Boot Image," on page 179.

STEP 1. Your storage system shipped with a null modem serial cable (service cable) that is unused except for service. In some cases, an extra RJ45—DB9 adapter was shipped with the service cable.

If your service cable has a DB9 connector on one end and an RJ45 connector at the other, skip this step and continue with STEP 2.

If your service serial cable has DB9—DB9 connectors, you also need the RJ45—DB9 adapter cable supplied with your system; connect the serial cable and adapter together.

The null modem cable and SPS sense cable look similar but are not interchangeable. If your system shipment included two RJ45—DB9 adapters, either works.

STEP 2. Connect the service serial cable between a server or laptop s COM 1 or COM 2 port and service port of the SP that does not boot.

Figure 62 shows a cable connection between a COM port and SP A.
