This microcontroller is connected to the -board's LED, fan, digital thermometer, power switch, and main processor, the -MPC8241. The connection to the main processor is through the 8241's second -UART and possibly its reset lines. - -The microcontroller can perform the following functions: - o The LED can be set to off, blue, red, blue flash, red flash, - alternate (blue->red->blue) and some boards alternate3 - (blue->blue->blue->red->red->red). The flash and alernate rates - can be be set. Alternate3 rate is fixed. - o Fan can be set to on or auto. Auto mode is a thermostat function - that turns the fan on and off based on two temprature settings: - Fan Temp High and Fan Temp Low. - o The system can be reset, causing a MPC8241 reset, or stopped, - causing a full power down. - o The microcontroller can detect if the soft power switch has been - activated. There appears to a 20s delay after the power switch - has been depressed before the microcontroller causes an actual - power off. This event can be detected by polling the - microcontroller. - -The running system communicates with microcontroller and ultimately controls -the devices connected to it via the MPC8241's second UART. The connection -settings are: 9600,8,n,1. The serial protocol is very simple, an alternating -send and receive of data packets. Communication is done in 8 byte data packets -and is initiated by the host processor. Once the host processor has sent 8 -bytes, the microcontroller responds with 8 bytes. The packet contains bytes -that can affect the state of the power, led and fan. It also contains bits -reflecting external soft power events. Both packets sent and received follow -the same structure. - -The 8 bytes are decoded as follows: - - 0 1 2 3 - 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Power | LED | LED | Fan | - | State | State | Flash Rate | State | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - | Fan High Temp | Fan Low Temp | | | - | ON | OFF | ID | CheckSum | - +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ - - Hex Ascii Comments - --- ----- -------------------------------------------------- -Power State: - 0x62 b Running, nominal running state - 0x63 c Stop, power down immediately (ID == HOST) OR - Stop, the power switch has been activated, stop in 20s - (ID == CONTROLLERxx) OR - Stop, the host has advised Stop - (ID == CONTROLLERxx) - 0x64 d Advise Stop, the host is annoucing its intention - to stop (ID == HOST) - 0x65 e Restart, restart immediately (ID == HOST) OR - Restart, the host has advised Restart - (ID == CONTROLLERxx) - 0x66 f Advise Restart, the host is annoucing its intention - to restart (ID == HOST) - 0x67 g Reset, reset immediately (ID == HOST) OR - Reset, the host has advised Reset - (ID == CONTROLLERxx) - 0x68 h Advise Reset, the host is annoucing its intention - to reset (ID == HOST) - -Except for Running, the Power states are grouped in pairs: Advise [state] and -[state], where state can be: Stop, Restart, or Reset. The Advise state lets -the controller know that there is an intention to either stop, restart or -reset the board. The controller responds by moving to that state and setting -the LED to redflash, but it does not enact the power change. Instead it waits -for the host to issue the actual state before performing the power commands. -For example, assume the microcontroller is reporting the power state to be -[Running, LED Blue]. After the host issues a Advise Stop, the microcontroller -reports [Stop, LED Redflash] and then waits, indefinitely. The Host then -issues a Stop, the microcontroller immediately turns the power off. - -There is nothing in the protocol that requires the Advise [state] packets. The -Host can issue a Stop, Restart, or Reset directly from the Running state and -the microcontroller will immediately enact the change. - -There is nothing in the protocol that forbids moving back to Running from the -Stop, Restart or Reset states, i.e. undoing an Advise [state] packet. - -The exception to that rule is in the Stop state. The Stop state can be reached -by either issuing a Advise Stop or from a softpower switch activation (someone -hits the power switch). If the latter, then a request to move to any other -state is ignored and the power will go off in approximately 20s. - -NOTE 1: There does not appear to be any difference in processing the Restart -and Reset state changes. They both deliver a system restart. - -NOTE 2: Obvious absence of an 'a' state. Both the LED and Fan controls use 'a' -as a state, but Power starts with 'b'. No evidence has shown 'a' to be a -valid state. - -LED State: - 0x61 a Off - 0x62 b Blue - 0x63 c Red - 0x64 d Blue Flash - 0x65 e Red Flash - 0x66 f Alternate1 Blue/Red - 0x67 g Alternate3 3 Blue/3 Red (only on version 5.x boards) - -LED States are self explanatory with one exception. Although state 'g' or -Alternate3 has been observed, it only seems to function on IOMEGA G2 Version -5.x boards and does not respond to rate changes. - -LED Flash Rate: -The flash rate seems to be 1/x seconds on, then 1/x seconds off. So one cycle -of off and on at an LED Flash rate of 1 is almost 2s. The value spans 8 bits -but functionally 0 is off and 36-40 is on. Testing has shown an oddity, the -value 35 is rejected by the microcontroller software and is not set. - -Fan State: - 0x61 a Auto thermostat function - 0x62 b On always on - -Fan High Temp: -High Temp is the temprature in Celsius where the fan is be turned on. - -Fan Low Temp: -Low Temp is the temprature in Celsius where the fan is be turned off. - -ID: -The real purpose of this field is not known. It is known that it is a constant -depending upon the direction of the packets and the board rev. It has been -designated ID as a place holder but it could as easily be defined as version -or it may be something else entirely. - - 0x00 DC2 CONTROLLER00 - IOMEGA G2 Version 5.x Controller ID (recv'd packets) - 0x07 BEL HOST (sent packets) - 0x12 DC2 CONTROLLER12 - IOMEGA G2 Version 3.x Controller ID (recv'd packets) - -Checksum: -The check sum is an 8 bit sum of the first 7 bytes with the most significant -bit cleared. - - Sum = ((b1 + b2 + b3 +b4 +b5 +b6 + b7) & 0x7f) - -The bytes and their meanings were determined by watching the serial port -chatter during specific events such as LED Blue, LED Red, Fan ON, etc. So only -events observed have been decoded. Although all the significant events were -observed and decoded, there are some holes in the understanding of the -protocol. - -There is one special packet that causes the microcontroller to reset. This -packet is: - 0x23696f6d 0x65676115 - (or as a string "#iomega\025") - -The resulting packet from the microcontroller is: - 0x62000000 0x00000062 - -Testing also yielded that a null packet will cause the microcontroller to -feed back the current state. So this packet: - 0x00000000 0x00000000 - -will yield something like this (this is the default state): - 0x62620a61 0x322d1220 - -The default state when the board powers on is: - State: Run - LED: Red - LED Rate: 10 - Fan: On - Fan Temp High: 50C - Fan Temp Low: 45C - -Below is some of the data collected while watching the serial port chatter: - -w: 0x23696f6d 0x65676115 #iomega\025 -r: 0x62000000 0x00000062 b\0\0\0\0\0\0b -w: 0x62630a61 0x322d0716 bc\na2-\7\26 red state -r: 0x62630a61 0x322d1221 bc\na2-\22! -w: 0x62641161 0x322d071e bd\21a2-\7\36 blue flash -r: 0x62641161 0x322d1229 bd\21a2-\22) -w: 0x62641161 0x322d071e bd\21a2-\7\36 blue flash - -LED ok -w: 0x62620a61 0x322d0715 bb\na2-\7\25 -r: 0x62630a61 0x322d1220 bb\na2-\22 - -LED alt -w: 0x626f0a61 0x322d0719 bf\na2-\7\31 -r: 0x626f0a61 0x322d1224 bf\na2-\22$ - -reset -w: 0x68620a61 0x322d071b hb\na2-\7\33 reset -r: 0x67620a61 0x322d0013 gb\na2-\0\23 resetting - -restart -w: 0x66620a61 0x322d0719 fb\na2-\7\31 restart -r: 0x65620a61 0x322d1223 eb\na2-\22# restarting - -shutdown -w: 0x64620a61 0x322d0717 db\na2-\7\27 shutdown -r: 0x63620a61 0x322d1221 cb\na2-\22! power shutting down - -soft Power -r: 0x63620a61 0x322d000f cb\na2-\0\17 power shutting down - - - - - - - - - - - - - diff --git a/packages/sccd/files/init-sccd b/packages/sccd/files/init-sccd deleted file mode 100644 index 372bfeae91..0000000000 --- a/packages/sccd/files/init-sccd +++ /dev/null @@ -1,38 +0,0 @@ -#! /bin/sh -# -# This is an init script for open protium for storcenter -# Copy it to /etc/init.d/sccd and type -# > update-rc.d sccd defaults 60 -# -sccd=/sbin/sccd -test -x "$sccd" || exit 0 - -case "$1" in - start) - echo -n "Starting StorCenter Control Daemon" - start-stop-daemon --start --quiet --exec $sccd - echo "." - ;; - stop) - echo -n "Stopping StorCenter Control Daemon" - start-stop-daemon --stop --quiet --pidfile /var/run/sccd.pid - echo "." - ;; - reload|force-reload) - start-stop-daemon --stop --quiet --signal 1 --exec $sccd - ;; - restart) - echo -n "Stopping StorCenter Control Daemon" - start-stop-daemon --stop --quiet --pidfile /var/run/sccd.pid - echo "." - sleep 1 - echo -n "Starting StorCenter Control Daemon" - start-stop-daemon --start --quiet --exec $sccd - echo "." - ;; - *) - echo "Usage: /etc/init.d/sccd {start|stop|reload|restart|force-reload}" - exit 1 -esac - -exit 0 diff --git a/packages/sccd/files/scc-disk.c b/packages/sccd/files/scc-disk.c deleted file mode 100644 index 4fd494203a..0000000000 --- a/packages/sccd/files/scc-disk.c +++ /dev/null @@ -1,167 +0,0 @@ -/* - * Copyright (c) 2006 - * Protium Computing, Inc.

It does this -either by sending a message to the StorCenter Control Daemon, if available, -or directly communicating with the StorCenter's microcontroller responsible -for these devices. -.PP -The scc utility can perform the following functions: -.TP -\fB\fR -The LED can be set to off, blue, red, blue flash, red flash, -alternate (blue->red->blue) and on some boards alternate3 -(blue->blue->blue->red->red->red). The flash and alernate rates -can be be set. Alternate3 rate is fixed. -.TP -\fB\fR -Fan can be set to on or auto. Auto mode is a thermostat function -that turns the fan on and off based on two temprature settings: -Fan Temp High and Fan Temp Low. -.TP -\fB\fR -The system can be reset, causing a StorCenter reset, or stopped, -causing a full power down. -.SH OPTIONS -.TP -\fB\-?\fR -display this help and exit -.TP -\fB\-d\fR -send send directly, stop/restart only -.TP -\fB\-p POWER\fR -control soft power -.br -POWER=[run|off|restart] -.TP -\fB\-l LED\fR -control LED state -.br -LED=[off|blue|red|blueflash|redflash|alternate|alternate3] -.TP -\fB\-r RATE\fR -Rate the LED flashes (0<=RATE<256) -.TP -\fB\-f FAN\fR -control fan operation -.br -FAN=[auto|on] -.TP -\fB\-h TEMP\fR -Hot temp when FAN=auto should go on (0<=TEMP<256) -.TP -\fB\-c TEMP\fR -Cold temp when FAN=auto should go off (0<=TEMP<256) -.SH NOTES -Care should be taken when changing the LED. The boot scripts and the -.B sccd -daemon use LED colors to indicate boot and disk activity. Changing the LED can -cause some of these functions to be disabled. -.SH AUTHOR -Written by Philip Kufeldt. -.SH "REPORTING BUGS" -Report bugs at www.openprotium.org. -.SH COPYRIGHT -Copyright \(co 2006 Protium Computing, Inc.
