When the SBB is removed, the LED pattern on the controller OCP changes to

solid amber, and normal operation on the ports resume. At this time, the removed

SBB’s port LED on the controller OCP turns on. The LED stays on until the SBB

is returned to its slot or until another SBB is inserted in the slot. The remaining

port LEDs on the controller OCP turn off.

5.5 Installing a Storage Device SBB

Use the following procedure to install a storage device SBB:

CAUTION

Use a replacement device of the same type as the removed device.

Otherwise, subsystem failures such as the establishment of stripesets

can occur.

1. Quiesce the SBB’s port by pressing and holding the port button on the

controller. Continue holding the button until all controller amber OCP LEDs

are on.

Note

Only one port can be quiesced at any time.

If the button is not held long enough, or multiple buttons are pushed in

quick succession, all buttons are ignored (no ports are quiesced). The

button must be pressed and held again to quiesce the port.

2. Wait until the chosen controller port LED ﬂashes alternately with the other

port LEDs (this indicates I/O has stopped). The alternating pattern ﬂashes

for approximately 30 seconds, during which time the SBB can be inserted.

If the pattern does not appear after a minute or two, another shelf is

asserting a fault signal that prevents any quiesce function on this controller.

To correct the problem, the suspect shelf must be located and all devices must

be removed.

While the controller OCP LEDs are ﬂashing, any SBBs on the quiesced port

will ﬂash their status LEDs.

Note

The length of time required for I/O to stop can vary from zero seconds to

several minutes, depending on load, device type, and cache status.

3. Holding the SBB in both hands, insert it into the guide slots and ﬁrmly push

it into the shelf until the mounting tabs snap into place.

4. Observe the status LEDs for the following indications: the Device Activity

(green) LED is either on, ﬂashing, or off. The Device Fault (amber) LED is

off.

5. Restore the device to the conﬁguration. See the StorageWorks Array

Controllers HS Family of Array Controllers Service Manual.
