General Switch Status LED
The switch status LED located on the rear panel indicates overall switch failures
(Table 6–2).
TABLE 6–2
SCI Switch Rear Panel LED
Situation LED Status
Fatal switch errors:
fatal hardware error,
temperature too high,
fan(s) not operative,
power supply problem
Red
Switch operational Green
The
get_ci_status
Command
You can use the results of the
get_ci_status
command to troubleshoot clusters
that have SCI switches. For example, for the configuration in Figure 6–2, if the
get_ci_statu
s command is used on interconn1, a typical output would be:
# /opt/SUNWsma/bin/get_ci_status
sma: sci #0: sbus_slot# 1; adapter_id 8 (0x08); ip_address 1; switch_id# 0; port_id# 0; Adapter Status - UP; Link Status
UP
sma: Switch_id# 0
sma: port_id# 1: host_name = interconn2; adapter_id = 72; active | operational
sma: port_id# 2: host_name = interconn3; adapter_id = 136; active | operational
sma: port_id# 3: host_name = interconn4; adapter_id = 200;inactive|inoperational
#
In this example, the line
sma: port_id# 3: host_name = interconn4; adapter_id = 200;inactive|inoperational
indicates that the path between SCI switch 0, port 3 and interconn4 is inactive and
not operational.
