When SSRR is activated on SE39x0 systems, customers cannot power down the
system safely on their own. The security measurements taken for the SP, a
component of SE39x0, prevents users from accessing the SP for shutdown.
The "Sun StorEdge 3900 and 6900 Series Installation and Service Manual"
(816-3244) and "Sun StorEdge 3900 and 6900 Series 2.0 Reference and Service
Manual" (816-5253) reference shutdown procedures for all systems WITHOUT
SSRR being activated.
Sun Service Support personnel are unable to shut down SE39x0 systems
remotely in the following circumstances:
-Loss of remote access to SSRR bound SE39x0 subsystems.
-Emergency shutdown to prevent power failure due to lack of appropriate
backup power from UPS.
Customers can shut down the SE39x0 storage subsystems safely by
utilizing the following power up and power down procedures:
To power down a SE39x0, do the following:
1. Stop all I/O from hosts to SE39x0 LUNs by shutting down hosts or quiescy
I/O to LUNs.
2. Open rear door of SE39x0 and locate the SP in the upper part of rack.
3. Shut down the SP:
	- Find the rocker switch for power on/standby, located on the left
side(rear) of the SP.
	- Push down the rocker switch for less than 3 seconds. This will
shut down the OS and switch off the SP to standby operation.
	
Note: The power supply and fans are down. Only the SP's LOM (Lights Out
Management) module is active, with its power being provided from
AC input.
4. In the rack, locate all T3 arrays.
5. Power off the T3ES as follows:
	- On each T3 brick, locate the pushbuttons on the two PCUs.
- Push each button once. LEDs for both PCUs will be amber.
	- Observe the PCU LEDs to turn off:
		- The left LED (AC power) should remain amber.
		- The right LED (PS LED) should turn off in approximately 2
minutes.
6. Switch off the SE39x0 power:
	- Ensure that the shutdown for all T3s is complete. The AC LED is
amber, PS LED is off, and the SP is powered off.
Note: For SE3960, no special shutdown procedure is required for
the FC switches.
	- Turn the key switch in front of the SE39x0 (bottom panel) to
	  "standby" position. This will switch off the power sequencer
inside the SE39x0.
To power up a SE39x0, do the following:
1. Check if the sequencer AC power indicator is on, indicating that AC
is provided to both sequencers.
2. Switch on the SE39x0 power:
	- Turn the key switch in front of the SE39x0 (bottom panel) to
"on" position. This will switch on the power sequencers inside
the SE39x0.
3. Open the rear door of SE39x0 and locate the T3 bricks.
4. Check the status of the T3 bricks and FC switches:
	- Check that all T3 PCU have the left LED (AC LED) on.
The indicator light should be amber.
	- For SE3960, check that the FC switches have been powered on. The
indicator light on the far left should be green.
5. Power on the T3ES:
	- On each T3 brick, locate the pushbuttons on the two PCUs.
- Push each button once. Both LEDs will turn green.
	- After a very short time, the right PS LED (green) will start to
blink. This indicates that a charging cycle is going on after the
power outage.
	- Wait for all the bricks to show the controller status LED: (right
side of controller left to the reset switch) to turn into green
6. Resume I/O from hosts to SE39x0 LUNs:
- Boot hosts connected to the SE39x0 LUNs or resume access to LUNs
	  (the operation of the LUNs is independent to the SP function, so
it doesn't need to have the SP operating at this time)
7. Power on the SP:
	- Locate the SP in the upper part of rack.
	- Find the rocker switch for power on/standby on the left side
(rear) of the SP.
	- Push down the rocker switch for less than 3 seconds. This will
switch on the SP and start the OBP/OS, allowing the SP to boot in
multiuser mode.
	- If possible, check the connection to the SP by contacting
StorADE on the configured access port (7654, 7443 or 9443) with a
Web browser
- If there is no open case about the power down, open a case to
verify that the SSRR infrastructure is up and running
