- | After disk modules arrive at the stations, they ideally need to be conditioned before use. | + | After disk modules arrive at the stations, they should be **conditioned** before use. |
+ | Conditioning performs a read/write cycle over the set of disks and identifies and isolates bad sectors. | ||
+ | |||
+ | **__To Condition a module:__** | ||
+ | |||
+ | Place the module in Bank A **(Leave Bank B empty or unlocked)**. | ||
+ | |||
+ | On a terminal window on the ops1xx pc enter: <code> | ||
+ | ssh oper@mk5xx </code> | ||
+ | to log onto the Mark5B where xx = yg, ke or hb. Then ensure Dimino is not running by typing:<code> | ||
+ | Enddim </code> | ||
+ | Start the conditioning program:<code> | ||
+ | ./condition "logfile" </code> where "logfile" is the output log file for SSErase - usually use the modules vsn for the logfile name. eg: **//./condition HOB+0061//**. The logfile will be placed in ./scripts/. | ||
+ | |||
+ | The program will mention this is going to take a long time (see [[hardware:mark5.conditioning.times | Conditioning times]] ) | ||
+ | and ask you if you are sure you want to do this but it won't wait for an answer - it will start automatically. | ||
+ | |||
+ | After many seconds, you should see the program output its first line of info. | ||
+ | |||
+ | When the routine completes , it will say how many seconds it took - **note this, to write on the side of the module**. Ensure the time taken is close to normal for that size module - if it is radically different - try conditioning the module again. | ||
+ | |||
+ | If the script gets in a real tangle, you can usually ctrl-c it and then reset the Mark5 with: <code> SSReset </code> and try again. | ||
+ | |||
+ | It is a good idea to do some [[hardware:mark5.conditioning.postconchecks | post conditioning checks]] | ||

+ | Mark5B manual is here : http://www.haystack.mit.edu/tech/vlbi/mark5/docs/Mark%205B%20users%20manual.pdf |
