EMC Recover Point – how to recreate repository volume
We have to recreate repository volume of our RP but I could not find any guidance from EMC site. So I’m documenting my steps here for further usage:
Procedure overview:
On EMC storage:
- Create about 6-8 GB LUN.
- Present that LUN to storage group of RP nodes.
On RP appliances:
On last cluster member:
- Detach RPA from cluster
- Format repository volume
- Reboot
- Attach RPA to cluster
On each subsequent appliance:
- Detach RPA from cluster
- Select repository volume
- Reboot
- Attach RPA to cluster
This is a transcript of console sessions:

Car diagnostic with ATmega328P Nano
I was in trouble reading my car’s live data. So I’ve wrote a little utility to read raw car sensors data i.e. i hook up before ECU and send it via serial port to PC using ATmega328P Nano and finally store it to file.
Where to get one:
http://www.banggood.com/ATmega328P-Nano-V3-Controller-Board-Compatible-Arduino-p-940937.html
How to install:
1. Flash AnalogReadSerial.hex to ATMega.
2. Extract and run carauto. .Net 4 is needed.
3. Choose com port from dropdown menu.
How to use:
Connect analog/digital input to intended sensor via 1KOmh resistor. Please note that all inputs are 5V only!
Shorting digital Input 12 to ground will produce human readable data and will decrease sample rate.
Reading data:
Data are stored in Output.csv file with approximately 1000 samples/second.

Openvpn on OpenWRT does not start
with error:
|
1 |
Sat Mar 14 20:48:43 2015 TCP/UDP: Socket bind failed on local address [AF_INET]192.168.0.254:1194: Cannot assign requested address |

|
1 2 |
sleep 10s /etc/init.d/openvpn start |
Charger: OEM vs. “chinese”
OEM has more parts in it, has bigger transformer, weights more, gives more amps and output voltage is stable. Chinese is cheeper. it is difficult or impossible to tell the difference without opening it (or measure weight).
| Current(A) | Voltage(V) | Weight(g) | |
| OEM | 1 | 5.00 | 37 |
| Chinese | 0.5 | 4.5 | 22 |
