How to Replace a Controller Card, FC Switch, or Disk Tray-to-Switch Component in a Running Cluster

Use this procedure to replace a failed disk tray controller card, an FC switch, or the following disk tray-to-switch components in a running cluster:

• Fiber optic cable that connects an FC switch to a disk tray

• GBIC on an FC switch, connecting to a disk tray

• StorEdge network FC switch-8 or switch-16

• FC switch power cord

• Media Interface Adapter (MIA) on a StorEdge T3 disk tray (not applicable for StorEdge T3+ disk trays)

• Interconnect cables between two interconnected disk trays of a partner-group

1. Telnet to the disk tray that is connected to the controller card, FC switch, or component that you are replacing.

2. Use the T3/T3+ sys stat command to view the controller status for the two disk trays of the partner group.

   In the following example, both controllers are ONLINE.

   t3:/:<#> sys stat Unit State Role Partner ----- --------- ------ ------- 1 ONLINE Master 2 2 ONLINE AlterM 1

   See the Sun StorEdge T3 and T3+ Array Administrator's Guide for more information about the sys stat command.

3. Is the controller card, FC switch, or component that you are replacing attached to a disk tray controller that is ONLINE or DISABLED, as determined in Step 2?

   • If the controller is already DISABLED, go to Step 5.

   • If the controller is ONLINE, use the T3/T3+ disable command to disable it. Using the example from Step 2, if you want to disable Unit 1, enter the following:

     t3:/:<#> disable u1

   See the Sun StorEdge T3 and T3+ Array Administrator's Guide for more information about the disable command.

4. Use the T3/T3+ sys stat command to verify that the controller's state has been changed to DISABLED.

   t3:/:<#> sys stat Unit State Role Partner ----- --------- ------ ------- 1 DISABLED Slave 2 ONLINE Master

5. Replace the component using the following references:

   • For the procedure on replacing interconnect cables, see the Sun StorEdge T3 and T3+ Array Installation, Operation, and Service Manual.

6. If necessary, telnet to the disk tray of the partner group that is still online.

7. Use the T3/T3+ enable command to reenable the disk tray that you disabled in Step 3.

   t3:/:<#> enable u1

   See the Sun StorEdge T3 and T3+ Array Administrator's Guide for more information about the enable command.

8. Use the T3/T3+ sys stat command to verify that the controller's state has been changed to ONLINE.

   t3:/:<#> sys stat Unit State Role Partner ----- --------- ------ ------- 1 ONLINE AlterM 2 2 ONLINE Master 1
