Formatting and Verifying Disk Drives

You can use the disk utilities to low-level format or verify your disk drives. (New disk drives are

low-level formatted at the factory and do not need to be low-level formatted again.)

Caution:

Before you format a disk drive, back up all data. Formatting destroys all data on

a disk drive.

To format or verify a disk drive:

1 Start the ARC utility (see page 97).

2 Select the controller you want, then press Enter.

3 Select Disk Utilities.

4 Select the disk drive you want, then press Enter.

5 Select Format Disk or Ve r ify D isk Me d ia .

Locating Disk Drives

Note: This feature is only available with disk drives that have an activity LED.

You can use the Identify Drive feature to physically locate a disk drive by blinking the LED.

To locate a disk drive:

1 Start the ARC utility (see page 97).

2 Select the controller you want, then press Enter.

3 Select Disk Utilities.

Spin Up Limit (Internal) The number of internal drives to be spun up at any given moment. By

default it is set to 0. In the default setting, all the internal drives will

spin up.

Spin Up Limit (External) The number of external drives to be spun up at any given moment. By

default it is set to 0. In the default setting, all the external drives will

spin up.

Option Description

PHY Rate The data transfer rate between the controller and devices. The default setting is

Auto, which allows the SAS card to adjust the data transfer rate, as needed. For

low-port 5-series RAID controllers (5085, 5405), you can set the PHY rate to

1.5Gb/second or 3.0Gb/second (the maximum rate).

CRC Checking When enabled, determines whether the controller verifies the accuracy of data

transfer on the serial bus. Default setting is Yes (enabled). Set to No (disabled)

only if the controller is connected to a device that does not support CRC Checking.

SAS Address In a situation where you want each phy on a controller to be in a different SAS

domain, this setting specifies a unique world-wide name for each phy. Default

is 0.

Note: This setting is for SAS address conflict resolution only and should otherwise

remain at its default value.
