4 Monitoring DC SAN Director system components This chapter provides the following information on interpreting LEDs to monitor the following DC SAN Director components: • "Monitoring Director blade status" on page 57 • "Monitoring Control Processor blade (CP8) status" on page 64 • "Monitoring core switch blade (CR8) status" on page 66 • "Monitoring power supply status" on page 68 • "Monitoring blower assembly status" on page 69 • "Monitoring WWN bezel (logo plate) and WWN card status" on page 71 Introduction The DC SAN Director is engineered for reliability and requires no routine operational steps or maintenance. This chapter provides information about determining the status of each component using LEDs and CLI commands. Monitoring Director blade status To determine the status of a Director blade: 1. Check the LEDs on the blade. • Figure 15 shows the FC8-16 • Figure 16 shows the FC8-32 • Figure 17 shows the FC8-48 • Figure 18 shows the FC10-6 • Figure 19 shows the FR4-18i 2. The LED patterns may temporarily change during POST and other diagnostic tests. For information about how to interpret the LED patterns, see Table 9. 3. Type slotShow to check blade status. Table 9 on page 63 describes the Director blade LED patterns and the recommended actions for those patterns. HP StorageWorks DC and DC04 SAN Backbone Director Switches 57
