Verifying Logical Drives - Adaptec CDP-00278-01-A User Manual

Performance Mode
To select a performance mode for the logical drives on a controller:
1. In the Enterprise View, select a controller, then select a logical drive on that controller.
2. On the ribbon, in the Logical Disk group, click Set Properties.
The Set Properties window opens.
3. In the Performance Mode drop-down list, select the application type: Dynamic or OLTP.
4. Click OK.
5. Shutdown maxView Storage Manager and reboot the system.

Verifying Logical Drives

To ensure that there are no data problems on your logical drives, it is important to verify them. When
you verify a logical drive, maxView Storage Manager checks it for inconsistent or bad data and then
fixes any problems. (You can also choose to verify a logical drive without fixing it.)
Logical drives without redundancy (for instance, RAID 0 logical drives) do not need to be verified.
In maxView Storage Manager, logical drive verification can occur in different ways, depending on your
controller:
• Automatic verification—If your controller supports Build initialization, maxView Storage Manager
automatically verifies all new redundant logical drives. No manual verification is required.
To see if your controller supports Build initialization, select the controller in the Enterprise View
then, on the Storage Dashboard, click Properties.
• Manual verification—If your controller doesn't support Build initialization, a Warning-level event
notice appears in the event log prompting you to verify a logical drive before you begin to use it. To
verify a logical drive manually, see
• Background verification—If your controller supports background consistency check, maxView Storage
Manager continually and automatically checks your logical drives once they're in use.
To see if your controller supports background consistency check, select the controller in the Enterprise
View then, on the Storage Dashboard, click Properties. To enable or disable background consistency
check or to set the checking period, see
If your controller doesn't support background consistency check, we highly recommend that you verify
your logical drives weekly, following the instructions in
