View source for ReleaseEngineering/How To/Create new slaves or move them to other pools

The intention of this page is to contain information about what to do when:
* a new machine that has never existed before is added to the pool
** for one of these reasons:
*** we've purchased more of the same host
*** we've re-purposed (e.g. Win7 slaves instead of WinXP)
* the machine is being moved between pools (e.g. build pool to try pool)

Here's what IT needs to get done to help you ('''when a non-existent machine is being added'''):
* DNS changes
* re-labeling (DCOps)
* attach dongles if the machines are running OSX

If you're replacing an Android panda go [[ReleaseEngineering:How_To:Android_Tegras#Moving_replacement_pandas_into_production|here]]

Here's what it takes to re-purpose machines or mobile boards on our side:

NOTE: Each host type might have Post-imaging steps: [[ReleaseEngineering/How_To/Set_Up_a_Freshly_Imaged_Slave|Setup freshly imaged slave]]

'''graph server instructions'''
* login to cruncher and switch to the root account
* ask for the gpg file that contains the credentials and double decrypt it
* connect to the graphs DB to add the machines
* build slaves post to the graph server some data after uploading
** but you don't need to add individual machines IIUC since they post as a unique machine name ($OS_$branch)

'''slave alloc instructions'''
* login to relengwebadn.private.scl3.mozilla.com
* slavealloc.txt.gpg contains the credentials
* /data/releng/www/slavealloc/slavealloc dbimport -D $db_url --slave-data mydata.csv
* more details in [[ReleaseEngineering:Buildduty:Slave_Management#Adding_a_slave|adding a slave]]

'''staging machines'''
* see {{bug|808043}} if the slaves were staging machines and need the outbound traffic blocks to be removed
