Practical Use Note of Gammu

# Installing Gammu

apt-get install gammu

# Connecting The Modem

after the modem is plugged in,

find that the modem is detected with: dmesg | grep tty

ussually if the interface is USB, it'll shows ttyUSB0 and ttyS0 for serial, you'll need this for configuring gammu next..

# Configure Gammu

vi /etc/gammu-smsdrc

# Check It

please make sure that gammu service is not active.

root@pcsimv:~# gammu --identify

Delete Local Storage Repository on xenServer

While this can be done by XenCenter (see XenCenter's help section), there are other way to do it:

1. First, you have to determine the Storage-Repository-UUID:

xe sr-list

-> write down / take note of SR-UUID of the SR to delete

2. Find the corresponding Physical Block Device (PBD):

xe pbd-list sr-uuid=your-SR-uuid

-> write down / take note of PBD-UUID of the PBD to unplug and delete

3. Unplug the PBD:

xe pbd-unplug uuid=your-PBD-uuid

4. Delete PBD:

xe pbd-destroy uuid=your-PBD-uuid

5. Delete the association of your SR and the PBD:

xe sr-forget uuid=your-SR-uuid
