Notes on using Smart Tiers
•
When pool-VOLs with the available monitoring information are added in a pool, tier relocation
is performed. When pool-VOLs with no available monitoring information are added in a pool,
the page usage rate is averaged out in a tier.
•
If the pool-VOL is the external volume, set Enable for Cache Mode.
•
If the pool-VOLs are added, the tier relocation being performed stops.
