Removing FAS900 series clustering hardware

Removing FAS900 series clustering hardware  Top

To remove FAS900 series clustering hardware and recable the node's disk shelves, complete the following steps.

Step

Action

1

Halt both nodes by entering the following command on each console:

halt
2

Turn off the power to each node, then turn off the power to the disk shelves and unplug them from the power source.

3

Ground yourself, then remove the cluster interconnect cables from both nodes. See the Hardware and Service Guide for additional information.

4

If you are converting a cluster to a stand-alone appliance for a...

Then...

FAS940 or FAS960

Open both nodes, remove the cluster adapters, and then close the nodes.

FAS980 standard cluster

Remove the NVRAM5 adapter from slot 11 and install it in slot 10.

FAS980 MetroCluster

Completely remove the VI cluster adapter from slot 11.

5

Unplug the local node from the partner node's Channel B disk shelf and do the same for the partner node.

6

If you are converting to a...

Then...

System with nonmirrored disks

  1. Disconnect all cabling from the Channel B loop on the local node.
  2. Repeat for the partner node.

System with mirrored disks or a redundant Channel B loop

  1. Connect the local node to the open Channel B loop in its local disk shelves, as described in the appropriate disk shelf guide.
  2. Repeat for the partner node.
7

Power on the disk shelves, then the individual nodes, monitoring the system console for error messages during the boot process.

8

Run all system diagnostics at the boot prompt by entering the following command on the system console:

boot diags
9

Unset the partner system ID by entering the following command at the prompt:

unsetenv partner-sysid
10

Boot the node by entering the following command:

boot
11

Check clustering status by entering the following command:

cf status

Result

If clustering is disabled, you see the following output:

Cluster monitor not initialized
12

Repeat Step 1 through Step 11 for the partner node.
