Federal Government: Ignoring what we learned 5,000 years ago

January 20th, 2010

Being a volunteer EMT, and at times an outdoorsy-type person, I occasionally get emails from friends about disaster-related topics. Especially in the post-9/11 days. Recently, I got an email asking me if I’d seen the Department of Homeland Security’s disaster preparedness site, ready.gov. I’d heard a bit about it, but hadn’t really looked around. The site’s main premise is to educate people about how to prepare for a disaster – “get a kit”, “make a plan”, “be informed”.

The site’s own About page states that it is “designed to educate and empower Americans to prepare for and respond to emergencies including natural and man-made disasters. The goal of the campaign is to get the public involved and ultimately to increase the level of basic preparedness across the nation.”

The first step on the site, “Get a Kit”, includes a list of supplies to have on hand as a basic disaster kit. The introduction to the page reads:

You may need to survive on your own after an emergency. This means having your own food, water, and other supplies in sufficient quantity to last for at least three days. Local officials and relief workers will be on the scene after a disaster, but they cannot reach everyone immediately. You could get help in hours, or it might take days. In addition, basic services such as electricity, gas, water, sewage treatment, and telephones may be cut off for days, or even a week or longer.

.

I will admit, I assumed this would be geared more towards urbanites, not those of us in the suburbs or rural America (the latter generally being more accustomed to self-sufficiency), so I adjusted my expectations accordingly. At first glance, it seems to include most of the things that the EMT in me would want it to:

  • Food and water
  • First aid kit
  • Wrench or pliers to turn off gas line
  • Prescription medications
  • Bleach (as a disinfectant and for water purification)
  • Fire extinguisher
  • Matches

However, I found a number of things obviously missing. Sure, some are minor – matches but no mention of fuel, bleach but not even coffee filters to remove particulate matter from water. I also find it comical that so many years after the Cold War “Duck and Cover” approach to nuclear safety, the government is now telling people to Shelter-In-Place in the event of a biological attack – by covering their doors and windows with plastic sheeting!

But by far the most egregious omission from the list – something learned by man at least 5,000 years ago, and taught to every Boy Scout – is the simplest tool: a knife. Yup, that’s right, the Disaster Kit list doesn’t include any variety of cutting implement. I don’t know if whoever wrote up the list is just scared of getting sued when little Bobby finds the knife and kills himself, or whether they’re really that stupid. But I, for one, never leave my house without some variety of the oldest real tool devised by man, and can’t imagine anyone thrown into any sort of “survival” situation without at least a rudimentary way to cut, scrape, pry, etc. I’d say that if I were without utilities or organized public safety for “at least three days”, I’d sure want to be able to make simple repairs, fashion simple tools, or perhaps cut something.

On another (albeit less important) note, there are still many, many Americans, not just in rural areas, who have a fireplace or wood stove. What about a few days’ worth of wood?

Cable Management, Power Measurements, Major Outage, Cacti

March 6th, 2008

So, once again, still really busy. But a few new things.

First, my racks both at home and at the apartment are atrocious. They have no cable management at all. Both started with 1-3 machines, and no real plans for upgrades (since they’re just my personal/development machines). Unfortunately, the “rack” (a metal workshop shelving unit) at home now has 8 machines and a host of ancillary equipment. The one at the apartment – an actual 42U rack – has 5 plus a few switches, rackmount KMM, etc. They’re both a jumble of wires in the back. Unfortunately, it seems like cable management hardware is *epxensive*. $30 for a 2U metal blank with a few plastic split D-rings, or almost $40 for a 2-meter vertical hunk of plastic channel with slits in the sides? So, I’ve been vaguely considering what it will take to fabricate some cable management hardware of my own. Probably just building something out of rack blanks for the horizontal off of the switches, and buying some sort of vertical channel for power and networking/KVM. Man, those KVM cables sure do take up a lot of space. Also at the moment, at home my power is all coming directly out of two UPSs, whereas at the apartment it’s straight from mains off of a surge suppressor. I’s like to buy another UPS for the apartment from RefurbUPS.com, where I got the ones from home, and also add a PDU at home and a vertical power strip at the apartment.

Also, at the apartment, the roommates and I have had some discussion lately about how much power the machines draw. This mainly stemmed from our plans to move this June, into a rented house with two more people. This seems to be falling through, so I don’t have to worry about moving and re-cabling everything, but I’m still interested in finding out how much power is being drawn. Granted, my UPSs at home give me a more-or-less good idea of power consumption, but I’d like to know in detail. The ideal solution would be a clamp ammeter around the mains line to the equipment – one with a serial interface. Unfortunately, I can’t seem to find such a thing, short of a digital multimeter left on all the time. So, I guess I’ll be looking around, and if I can’t find anything specific, maybe I’ll work on a microcontroller that can read 1-200mV in 1mV increments, and use it with an inductive clamp ammeter (usual output for them is 1mV per A).

So, on Monday I got into work and couldn’t access my mailserver. Weird. I never even got any Nagios alerts. I checked Nagios and… nothing. As in no connection. I SSH’d home and pinged both boxes, but nothing. The switch showed the mail server totally offline, and the Nagios box plugged connected but ZERO data out. I reset the counters and waited. Still nothing. After an hour or so of poking around, I determined that both devices were on the same 6-port group on the switch, and nothing else there was up too. So, after five long hours, I got someone back home to switch the cables. Still nothing. On a hunch, I asked to have her check the mail server (the “new” Sun Blade 150) and, sure enough, it wasn’t powered on. A click of the power button, and the mail server was back online. Along with an ominous last email from Nagios, stating that the UPS running my switch lost power, and 6 minutes later, was going down hard. Then quiet.

I don’t usually have power outages. So I’ll admit, when I added some of the new machines, I committed a high sin – I “never got around” to setting up everything power-wise. I also have the switch running off of an old BackUPS 500VA unit, USB, without automatic self-tests. As a result of all this:

  1. The little UPS powering the switch only held out for 6-7 minutes. As a result, once that died, the bigger units didn’t even matter, as all hope was lost. This needs to be on a bigger UPS – maybe one of the 1000VA’s until it gets its’ own.
  2. APCupsd requires a network to initiate shutdown, so the rest of the machines came down hard (as confirmed by looking through log files).
  3. The SunBlade was never setup to power on after power interruption, so it just sat there like a brick.

Most disturbingly, while my Nagios/monitoring box is up (according to the switch, power draw figures from the UPS, and the lights, as confirmed by someone on-site), it’s dead. No ping, nothing out. I’ll have to look into it, but it made me realize that this really is my only way of analyzing problems. That needs to stop.

Maybe one day I’ll have the money for a nice SmartUPS RT or even a Symmetra – though getting 208V into my basement is even more of a dream than spending $4000 on a UPS.

Also, I decided (after all this) to setup graphing of UPS data (load, voltage in and out, temp, capacity, run time, etc.). While I haven’t gotten around to setting up Zenoss yet, I did a quick (well, 4 hours later I’m done configuring it) Cacti installation on my web server (I should already have it running on the monitoring box, but who knows what that will look like when I get home). I also dropped a Cacti host template in CVS for the AP9605 PowerNet SNMP card in my UPSs.
