Set or change the import passphrase

1. In the System topic, select Action > Full Disk Encryption.

The Full Disk Encryption panel opens with the FDE General Configuration tab selected.

2. Select the Set Import Lock Key ID tab.

3. In the Passphrase field, enter the passphrase associated with the displayed lock key.

4. Re-enter the passphrase.

5. Click Set. A dialog box will confirm the passphrase was changed successfully.

Configuring advanced settings

Use the Advanced Settings panel to change disk settings, cache settings, partner firmware update settings, and system utility settings.

Changing disk settings

The Disk tab provides options to change disk settings, including SMART configuration, EMP polling rate, dynamic spares, and drive spin

down options.

Configuring SMART

Self-Monitoring Analysis and Reporting Technology (SMART) provides data that enables you to monitor disks and analyze why a disk

failed. When SMART is enabled, the system checks for SMART events one minute after a restart and every five minutes thereafter.

SMART events are recorded in the event log.

Change the SMART setting

1. In the System topic, select Action > Advanced Settings > Disk.

2. Set the SMART Configuration option to one of the following:

• Don’t Modify. Allows current disks to retain their individual SMART settings and does not change the setting for new disks added

to the system.

• Enabled. Enables SMART for all current disks after the next rescan and automatically enables SMART for new disks added to the

system. This option is the default.

• Disabled. Disables SMART for all current disks after the next rescan and automatically disables SMART for new disks added to the

system.

3. Click Apply. If you chose to disable SMART, a confirmation panel appears. Click Apply to accept the changes or click Cancel.

Configuring the EMP polling rate

You can change the frequency interval that the storage system polls each attached enclosure’s management processor (EMP) for

changes to temperature, power supply and fan status, and the presence or absence of disks. Typically you can use the default setting.

• Increasing the interval might slightly improve processing efficiency, but changes in device status are communicated less frequently.

For example, this increases the amount of time before LEDs are updated to reflect status changes.

• Decreasing the interval slightly decreases processing efficiency, but changes in device status are communicated more frequently. For

example, this decreases the amount of time before LEDs are updated to reflect status changes.

Change the EMP polling rate

1. In the System topic, select Action > Advanced Settings > Disk.

2. Set the EMP Polling Rate interval. The options are 5, 10, or 30 seconds; or 1, 5, 10, 15, 20, 25, 30, 45, or 60 minutes. The default is 5

seconds.

3. Click Apply.

Configuring dynamic spares

The dynamic spares feature lets you use all of your disks in fault-tolerant disk groups without designating a disk as a spare. With dynamic

spares enabled, if a disk fails and you replace it with a compatible disk, the storage system rescans the bus, finds the new disk,

automatically designates it a spare, and starts reconstructing the disk group. A compatible disk has enough capacity to replace the failed
