Sun StorEdge SAN 4.0 Release Field Troubleshooting Guide • October 2002
Initialization Steps:
At power-on or reset, the following steps occur.
1. Preliminary POST diagnostics.
2. VxWorks operating system initialization.
3. Hardware initialization (resets, internal addresses assigned to ASICs, serial port
initialized, front panel initialized).
4. Full POST test.
5. Universal Port Configuration.
6. Link initialization—receiver/transmitter negotiation to bring connected ports
online.
7. Fabric analysis—the switch checks for ports connected to other Fabric elements. If
there are other Fabric elements connected, it identifies the master switch.
8. Address assignment—once the master switch has been identified, port addresses
may be assigned. Each switch tries to keep the same addresses that were
previously used. These are stored in the switch’s configuration flash PROM.
9. Routing table construction—after addresses are assigned, the unicast routing
tables are constructed.
10. Enable normal port operation.
Note –
If any of the steps listed above fails, replace the entire switch as a single
FRU.
