Is there any difference between the new Persistant dfs and the legacy dfs?
Can you mix them when you setup a logical volume?
Is there a performance difference?
Thanks,
Tim

Re: Persistant dfs
There is a pretty significatn_difference between persistent and legacy DSF. The "inbuilt" native multipathing feature on 11.31 now would normally see the LUN as the "LUN" itself. Legacy DSF's are based on "lunpath". 8 paths to the LUN give you 8 legacy DSF's but only one persistent DSF for that LUN. You_can mix them up as long as they are referring different LUNs or disks. However, this is not_recommended. Use the "persistent" DSF wherever possible. Legacy DSF's are present only for "backward compatibility". In terms of LVM there is a beautiful script called as vgdsf that allows for this migration.
> Performance difference
Agile addressing definitely provides better performance with default allocation policies which can be manipulated with the command scsimgr. PV links are definitely getting_deprecated.
