Note: You cannot add a second control enclosure to a Storwize V5010E system.
Procedure
To add a control enclosure to an existing system, complete the following steps.
1. Install the support rails for the new enclosure.
2. Install the new enclosure in the rack.
3. Connect the node canisters to the storage area network.
4. Configure the zoning on the SAN switches.
The correct zoning provides a way for the Fibre Channel ports to connect to each other.
5. Start the management GUI on the existing system.
6. In the management GUI, select Monitoring > System. On the System -- Overview page, select Add
Enclosure. When a new enclosure is cabled correctly to the system, the Add Enclosure action
automatically displays on the System -- Overview page. If this action does not appear, review the
installation instructions to ensure the new enclosure is cabled correctly. You can also add a new
enclosure by selecting Add Enclosure from the System Actions menu.
7. Complete the instructions in the Add Enclosures wizard until the control enclosure is added to the
system.
8. If only two control enclosures are in the system, you must set up a quorum disk or application outside
of the system. If the two control enclosures lose communication with each other, the quorum disk
prevents both I/O groups from going offline. For more information, see the "Configuring quorum" topic
in the IBM Knowledge Center.
