Adding a control enclosure to the clustered system by using the CLI

You can use the command-line interface (CLI) to add a control enclosure back into the system after it is either removed or rejected.

To add a control enclosure to a system, complete the following procedure:

1. Issue this CLI command to list the control enclosure candidates:

   lscontrolenclosurecandidate

   This output is an example of what you might see after you run the lscontrolenclosurecandidate command:

   
   serial_number product_MTM
   G00F7GY       2076-624

2. Issue this CLI command to add the control enclosure:

   addcontrolenclosure -iogrp 1 -sernum G00F7GY

   The 0 value is the I/O group where you add the control enclosure. The G00F7GY value is the serial number for the control enclosure.

   Note: In a service situation, add a control enclosure back into a system by using the original control enclosure name. When the partner control enclosure in the I/O group is not deleted, the I/O group name is the default when the -name value is not specified.

   The following example output might result:

   Enclosure containing Node, id [x], successfully added

   Attention: If more than one candidate control enclosure exists, add it into same I/O group to which it belonged before it was deleted. Failure to do so might result in data corruption. If you are uncertain about which candidate control enclosure belongs to the I/O group, shut down all host systems that access this system. Restart each system after you add all control enclosures back into the system.
3. Issue this CLI command to ensure that the node was added successfully:

   svcinfo lsnodecanister
