PHY Settings

 

 

 

 

 

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.

 

 

 

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:

1Start the ARC utility (see page 105).

2Select the controller you want, then press Enter.

3Select Disk Utilities.

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

5Select Format Disk or Verify Disk Media.

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:

1Start the ARC utility (see page 105).

2Select the controller you want, then press Enter.

3Select Disk Utilities.

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

5Select Identify Drive, then press Enter.

6When you have finished locating your disk drive, press any key to stop the blinking.
