Installing optional features

Optional hardware features can be installed in an enclosure. For example, network adapters.

The optional features that an enclosure supports are shown in the sales manual within the IBM Documentation. To find the relevant IBM Sales Manual, search “in all of IBM Sales manuals” for the machine type or the product name of the enclosure.

If an optional feature was ordered with the enclosure order, it is fitted at IBM manufacturing.

Pluggable network port modules (for example SFP) can be added or changed without powering off the node canister.

A node canister must be logically removed from the system (by using the rmnodecanister command) and powered off before adding or changing any network adapter to it.

When a node canister comes online with new adapters in it, the addresses of the ports might move. Some reconfiguration might be needed to restore all communication links before proceeding to update the next node canister. If portmasks or portsets are being used, they might need to be changed.

Always check that hosts, other Storage Virtualize nodes, and any back-end storage controllers can access the partner node canister before powering off a node canister.

Note: Wait for the power LED to start flashing (standby mode) before removing the node canister from the enclosure.

Use the management GUI to check that access to volumes is not lost if a node is offline. Host administrators can check that there are still paths to volumes if a node is offline.

If there are partnerships with other IBM® Storage Virtualize systems, use the management GUI to check that communication with the partner system is not lost when a node is offline.

Use the management GUI to power off or remove a node canister from the system. However, if the node is logically removed from the system, use the service assistant tool or CLI to power it off.

Use the management GUI to make any port configuration changes that might be needed to a node with new or different network adapters.
