If you want to view or change the current settings, see Starting the SCSISelect Utility. For detailed descriptions of each setting, see Using the Controller Configuration Utility.
To start SCSISelect:
Press <Ctrl><A> for Configuration Utility!
The menu Controller Configuration and SCSI Configuration options are displayed.
To select a SCSISelect menu option, move the cursor to the option with the and keys, then press Enter. In some cases, selecting an option displays another menu. You can return to the previous menu at any time by pressing Esc.
To restore the original SCSISelect default values, press F6 from the Configure/View Host Adapter Settings screen.
To toggle the display between color and monochrome modes, press F5 from the main SCSISelect screen (note, however, that this feature does not work on some monitors).
To exit SCSISelect, press Esc until a message prompts you to exit (if you changed any host adapter settings, you are prompted to save the changes before you exit). Select Yes to exit and reboot the system. Any changes you made in SCSISelect take effect after the server boots.
To access the Controller Configuration Utility, select the Controller Configuration option from the menu that appears after starting SCSISelect.
The following settings are the controller settings most likely to require any modification.
Caution: Disk drives with write-back cache enabled do not have the benefit of battery protection and could lose or corrupt data as a result of unexpected power loss or drive removal. |
Certain controllers may not support drives write cache. In those cases where drives write cache is not supported, setting the option to Enabled has no effect.
To access the SCSI Configuration Utility, select the SCSI Configuration option from the menu that appears after starting SCSISelect. Select the bus you want to configure and press Enter.
The following settings are the SCSISelect settings most likely to require any modification.
The SCSI device settings allow you to configure certain parameters for each device on the SCSI bus. To configure settings for a specific device, you must know the SCSI ID assigned to that device. If you are not sure of the SCSI ID, see Using the Disk Utilities.
To access the disk utilities, select the Disk Utilities option from the main menu that appears after entering the Configuration Utility and selecting the desired PERC 3/Di controller. Select the desired bus and press Enter. Once the option is selected, a list of all SCSI IDs and the devices assigned to each ID is displayed.
When you select a specific ID and device, a small menu appears, displaying the options Format Disk and Verify Disk Media.
Most SCSI disk devices are preformatted at the factory and do not need to be formatted again. The Format Disk utility is compatible with the vast majority of SCSI disk drives.
Caution: A low-level format destroys all data on the drive. Be sure to back up your data before performing this operation. Once started, you cannot abort a low-level format. |
Note: The controller should not be powered-off or rebooted during a disk format. Doing so may render the disk unusable until the format is manually restarted and completed. |
