Removing F800 series clustering hardware

Tasks for removing the hardware

Removing F800 series clustering hardware is a two-part process:

To recable your Channel B loops and convert your cluster to stand-alone storage systems, complete the following steps.

Note
This procedure assumes that you have DS14 disk shelves and dual Fibre Channel adapters.

Step	Action
1	Halt both nodes by entering the following command at each console: halt
2	Ground yourself, then power off the nodes and disk shelves.
3	Unplug the local node from the partner node's Channel B disk shelf and do the same for the partner node.
4	Connect the local node to the open Channel B loop in its local disk shelves.
5	Repeat Step 4 for the partner node.
6	Go to Removing the hardware.

To remove the clustering hardware and extra FC-AL adapters, complete the following steps.

Step	Action
1	Ground yourself, using the antistatic wrist strap.
2	Remove the interconnect cables from the cluster adapter.
3	Open the back of the local node, as described in the F800 Series Hardware Guide.
4	If applicable, unlock and remove the GBIC from the adapter (typically used with VI cluster adapters).
5	Unscrew the adapter from the chassis.
6	Remove the adapter.
7	Replace the slot cover and secure it with the screw from the adapter.
8	Remove any extra FC-AL or dual Fibre Channel adapters.
9	Close and secure the back of the storage system, as described in the F800 Series Hardware Guide.
10	Power on first the disk shelves and then the storage system; press the Delete key during boot to get to the OK prompt.
11	Unset the partner system ID by entering the following command at the OK prompt: unsetenv partner-sysid
12	Boot the storage system by entering the following command at the OK prompt: boot
13	Check the status of clustering on the storage system by entering the following command on the console: cf status Result Cluster monitoring is disabled, as indicated by the following message: `Cluster monitor not initialized`
14	Repeat Step 1 through Step 13 for the partner node.
