Tunesys
runs through 3 separate stages in order to rebalance the system these are:
Phase 1 –
Analyzes and rebalances virtual volume capacity imbalance between nodes
(inter-node tuning).
Phase 2 – Analyzes
and rebalances space usage between disks associated with each node (intra-node
tuning).
Phase 3 – LD
re-layout tunes. LDs where the current characteristics differ from the
associated
To see how things are progressing
leverage the showtask command and the GUI. A standard showtask –active will list all active tasks and
give you an overall view of the tunesys progress. If you make a note of the
task ID when you launch tunesys you can add that to the showtask command with
the –d switch to get a detailed output of the task progress.
