General Switch Status Led; The Get_Ci_Status Command - Sun Microsystems Sun HPC 3.0 Manual

General Switch Status LED

The switch status LED located on the rear panel indicates overall switch failures
(Table 6–2).

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_status 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.
