struct_i2c_bus_recovery_info - I2C bus recovery information
SYNOPSIS
struct i2c_bus_recovery_info {
int (* recover_bus) (struct i2c_adapter *);
int (* get_scl) (struct i2c_adapter *);
void (* set_scl) (struct i2c_adapter *, int val);
int (* get_sda) (struct i2c_adapter *);
void (* prepare_recovery) (struct i2c_bus_recovery_info *bri);
void (* unprepare_recovery) (struct i2c_bus_recovery_info *bri);
int scl_gpio;
int sda_gpio;
};
MEMBERS
recover_bus
Recover routine. Either pass driver's recover_bus routine, or i2c_generic_scl_recovery or i2c_generic_gpio_recovery.
get_scl
This gets current value of SCL line. Mandatory for generic SCL recovery. Used internally for generic GPIO recovery.
set_scl
This sets/clears SCL line. Mandatory for generic SCL recovery. Used internally for generic GPIO recovery.
get_sda
This gets current value of SDA line. Optional for generic SCL recovery. Used internally, if sda_gpio is a valid GPIO, for generic GPIO
recovery.
prepare_recovery
This will be called before starting recovery. Platform may configure padmux here for SDA/SCL line or something else they want.
unprepare_recovery
This will be called after completing recovery. Platform may configure padmux here for SDA/SCL line or something else they want.
scl_gpio
gpio number of the SCL line. Only required for GPIO recovery.
sda_gpio
gpio number of the SDA line. Only required for GPIO recovery.

ovdb_recover - Perform recovery on the ovdb database, if needed
SYNOPSYS
ovdb_recover [-f]
DESCRIPTION
Attempts to open the ovdb database, and if the database needs recovery, it attempts to perform the recovery. Similar in function to the
BerkeleyDB db_recover command.
Specify the `-f' option to force a recovery, even if the database appears to not need it. It is not an error to perform a recovery opera-
tion on a clean database. However, do not run `ovdb_recover -f' while the database is in use by any other processes.
Returns exit status of 0 if the database did not need recovery or if recovery succeeded, and returns exit status 1 if recovery failed. In
the latter case, the database may be damaged beyond repair, requiring a rebuild with makehistory(8).
This command is normally called automatically by rc.news(8).

How do I do mksysb backup on existing lpars for recovery purpose or how do I do all mksysb to a NFS mounted Filesystem... (1 Reply)
Dear guys
I am thanks for all to provide us these important subjects, which we need it in our work as system administrator, or technical support. As you know, In the Data center (disaster recovery) There are systems working under multi operating systems such as (AIX,HP Unix , sun... (1 Reply)
I have a 7029-6C3 that was running AIX 5.2; I tried to update to 5.2.10.5, rebooted, and the box went south. Upon further digging through the h/w logs, I found the error "Service Processor Firmware Failure"
I can't get the machine to boot - not even to CD. How can I recover from this? Or can... (10 Replies)
I'm sorting out the disaster recovery plan for a critical server. It's a Dell PowerEdge 2850 running Openserver 5.0.6a.
We have a disaster recovery agreement with HP and they have just confirmed that in the event of a total disaster such as the server being totally wiped out, they would NOT... (2 Replies)
Hey guys, I hope this is the right place to post. As i'm not too sure where this question would go.
The question is: How is backup and recovery carried out in major corporations. Even if you are not in a major corporation an answer would be great.
I'm doing some research as to how it's carried... (2 Replies)
This is a unlacky day! I deleted some data in my server by mistake. Please recommend me some data recovery programes. I don't want to carry the big thing to a company of data service.
Thanks very much to my friends (6 Replies)

I was recently working on a project where some gpio pins were being toggled from within the user space:
const char *const amplifierGPIO = "/sys/class/gpio/gpio107/value";
void amplifierUnmute()

std::ofstream amp(amplifierGPIO);
if (amp.is_open())
