"""A query for the location of one or more instance's ips. |

144 |
Given a list of instance IPs, returns an ordered list with the same |
|
145 |
number of elements as the input. Each element of the list is a tuple |
|
146 |
containing the status (success or failure) and the content of the |
|
147 |
query (IP of the primary node if successful, error constant if not). |
|
148 |
|
|
149 |
If a string (instance's IP) is given instead of a list it will return |
|
150 |
a single tuple, as opposed to a 1-element list containing that tuple. |
