Replacing an LRC

Hot-swapping an LRC

Assumptions about this procedure  Top

The assumption about this procedure is that both LRCs on the DS14 are multipath connections to the storage appliance.

Caution
If you attempt to hot-swap the LRC on a disk shelf which does not have multipath connections, you will lose all access to the drives on this disk shelf as well as those below it.

Hot-swapping an LRC  Top

To hot-swap an LRC, complete the following steps.

Step

Action

1

Put on the antistatic wrist strap and grounding leash.

2

From the console of the storage appliance, enter the following command to disable the loop in which the failed LRC is a connection:

storage disable adaptername

The Data ONTAP System Administrator's Guide (6.1 or later) provides more information about these commands.

3

Note the position of the terminate switch on the LRC you are removing and set the terminate switch on the replacement LRC to the same setting before inserting it into the disk shelf.

4

Disconnect the LRC that you are removing from the Fibre Channel cabling.

5

Using the thumb and index finger of both hands, press the levers on the CAM mechanism on the LRC to release it and pull it out of the disk shelf.

6

Slide the replacement LRC into the slot at the rear of the disk shelf and push the levers of the CAM mechanism into place.

Caution
Do not use excessive force when sliding the LRC into the disk shelf; you might damage the connector.

7

Reconnect the Fibre Channel cabling.

8

From the console of the filer, enter the following command to enable the loop in which the replacement LRC is a connection:

storage enable adaptername
