Identifying a node with the blink command
The blink command is used to physically identify a node. This command
forces the node attention light bar to blink or turns off blinking, provided
an error does not exist on the node.
Step 1. Bring up the sppdsh prompt at a sppuser window by entering:
$
sppdsh
Step 2. Use the blink command to cause the attention light bar to blink on a
specific node by entering the blink command followed by the node
number. For example:
sppdsh:
blink 0
For more information about the blink command see the sppdsh man
page.
Step 3. After you have physically identified the node cause the attention light
bar to return to a steady state by entering:
sppdsh:
blink 0
