Caution – When you rotate or replace drives, make sure that:

For overview information about drive LEDs and how they work, see “Front-Panel LEDs” on page 6-2.

You can check physical drive parameters using the firmware application. From the firmware Main Menu, choose view and edit scsi drives. For more information about the firmware application, refer to the SANnet II Family RAID Firmware User’s Guide.

Caution – When you rotate or replace drives, make sure that:

-All I/O is stopped.

-The “Periodic Drive Check Time” setting in the firmware application is set to disabled (this is the default setting). This prevents automatic drive rebuild, which is not recommended for live systems or troubleshooting.

To disable the Periodic Drive Check Time

1.From the Main Menu, choose view and edit Configuration parameters →Drive-side SCSI Parameters →Periodic Drive Check Time.

A list of Periodic Drive Check Time intervals is displayed.

2.Select Disable.

A confirmation message is displayed.

3.Choose Yes to confirm.

Caution – To prevent any possible data loss, back up user data to another storage device prior to replacing a disk drive.

The following flowchart provides troubleshooting procedures for the FC drive LEDs.

Set up an IP address for the controller 5.1.1 Point-to-Point Configuration Guidelines Caution - If you keep the default loop mode and connect to a fabric switch, the array automatically shifts to public loop mode. As a result, communication between the array and the switched fabric runs in half duplex send or receive instead of providing the full duplex send and receive performance of point-to-point mode 5.1.2 A Sample SAN Point-to-Point Configuration Remember these important rules Map LG1 to SIDs 45 and Note - These illustrations show the default controller locations however, the primary controller and secondary controller locations can occur in either slot and depend on controller resets and controller replacement operations 2.
