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.

Note: You must reboot the system for the performance mode setting to take

effect.

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

xes any problems. (You can also choose to verify a logical drive without xing it.)

Logical drives without redundancy (for instance, RAID 0 logical drives) do not need to be veried.

In maxView Storage Manager, logical drive verication can occur in different ways, depending on your

controller:

• Automatic verication—If your controller supports Build initialization, maxView Storage Manager

automatically veries all new redundant logical drives. No manual verication 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 verication—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 Verifying and Fixing a Logical Drive on page 58.

• Background verication—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 Enabling/Disabling Background Consistency Check on page 58.

If your controller doesn't support background consistency check, we highly recommend that you verify

your logical drives weekly, following the instructions in Verifying and Fixing a Logical Drive on page 58.
