[gpfsug-discuss] Question about Policies

Hi

As you said it migrate between different pools (ILM/External - Tape) - so 
in case you need to move directory to different location - you will have 
to use the OS mv command.
From what i remember there is no directory policy for the same pool.

Hi 
 
Thanks for your reply, once I have a set of files that are older than 30 
days would I then use the migration rule to move them ?
 
Looking at the migration Rule syntax implies a “From” pool and a “To” 
pool, I only have a single pool so would I use the same pool name for From 
and To ? if it is the same pool
How do I specify the folder to move it to which needs to be different from 
the current location.
 
Thanks
Kevin

Hi
 
I work for Cancer Research UK MI in Manchester UK. I am new to GPFS and 
have been tasked with creating a policy that will
Move files older that 30 days to a new folder within the same pool. There 
are a lot of files so using a policy based move will be faster.
I have read about the migration Rule but it states a source and 
destination pool, we only have one pool. Will it work if I define the same 
source and destination pool ?
 
Many thanks
Kevin
