To understand how different tiers are utilized by a Smart pool, compare the utilization of individual
RAID groups that constitute the Smart pool. You can see the utilization of individual RAID groups
and also the overall utilization of all the RAID groups. You must determine the drive types of the
individual Raid groups that constitute the Smart pool. Also, you need to know the RAID group for
which you want to determine the drive type. The RAID groups are listed under Pool Volumes in the
Pool Details table. For more information on identifying the drive type for a RAID group, see

Viewing continuous access data for P9000 disk arrays
The Array - View Continuous Access screen provides data on the continuous access configurations
(synchronous, asynchronous, and journal based) created in the selected XP or P9000 disk array.
The configuration data includes the P-VOL, S-VOL, and associated port, RAID group details. If the
P-VOLs and S-VOLs are configured based on the CTGs to which they belong, the configuration
data of journal groups that manage the corresponding I/O transactions are also displayed. To
view the continuous access data for a P9000 disk array, click Monitoring+Array View in the left
pane. Then, click the plus (+) sign for a P9000 disk array in the component selection tree and
select Continuous Access from the list displayed.
