3.13 Locating servers and SFS20 arrays
To help you to physically locate a server or an SFS20 array, the
sfsmgr
utility provides two commands that
turn on (or off) the blue unit identification (UID) LED on a server and the blue LEDs on an array, as follows:
• To turn on the UID LED (which is visible at the front and back of the server) on a specific server, enter
the
set server
command as shown in the following example:
sfs> set server south3 locator=on
Use the
locator=off
option to turn off the UID LED.
• If several servers have their UID LED turned on, you can turn them all off as shown in the following
example:
sfs> set server all locator=off
• To turn on the blue LEDs on the SATA drives in an SFS20 array, enter the
set array
command as
shown in the following example:
sfs> set array 3 locator=on
Use the
locator=off
option to turn off the blue LEDs.
The
all
option is not available with the
set array
command.
Note also that SFS20 arrays display a two-digit chassis number in an LED display at the back of the array.
This is the number that the
sfsmgr
utility uses in the
show array
command. The number is set when the
array is first configured by the
configure array
command. If there are more than 99 SFS20 arrays in
the system, the two-digit number wraps (so that the LED display on array 103 shows the value 03).
