Hot-swapping an LRC/ESH

Assumptions about this procedure

The assumptions about this procedure are that LRCs or ESHs on the disk shelf are multipath connections to the storage appliance and that you are hot-swapping an LRC with another LRC or that you are hot-swapping an ESH with an ESH.

For hot-upgrading or hot-downgrading these devices, see Hot-upgrading or hot-downgrading a disk shelf.

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

Hot-swapping an LRC/ESH

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

Caution
To hot-swap an LRC/ESH on a disk shelf that is in a cluster, see the Cluster Guide for your filer.

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/ESH is a connection: storage disable adapter adaptername The Data ONTAP System Administrator's Guide (6.1 or later) provides more information about these commands.
3	Note the position of the termination switch on the LRC/ESH you are removing and set the termination switch on the replacement LRC/ESH to the same setting before inserting it into the disk shelf.
4	Disconnect the LRC/ESH 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/ESH to release it and pull it out of the disk shelf.
6	Slide the replacement LRC/ESH 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/ESH 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/ESH is a connection: storage enable adapter adaptername
