8 Planning for configuration changes

This chapter identifies configuration changes that might result in a resource being taken offline temporarily or that might require that you make changes to multiple resources.

8.1 Configuration changes that require or result in resource outages

Appliance

Taking an appliance offline does not affect the managed resources—they continue to operate while the appliance is offline.

When you install an appliance update, the appliance is taken offline.

Enclosures

The Onboard Administrator is taken offline when you update firmware for an enclosure.

Interconnects and logical interconnects

•Server profile connections to networks in an uplink set are taken offline when you delete the uplink set.

•Server profile connections to networks in an uplink set can be interrupted for a few seconds when you change the name of an uplink set using either of these methods:

◦

◦

Change the name of the uplink set in the logical interconnect.

Change the name of the uplink set in the logical interconnect group, and then update the logical interconnect from the logical interconnect group.

•An interconnect is taken offline when you:

◦

◦

Update or activate firmware for a logical interconnect. Staging firmware does not require interconnects be taken offline.

Update firmware for an enclosure and select the option to update the enclosure, logical interconnect, and server profiles.

•If an interconnect has firmware that has been staged but not activated, any subsequent reboot of that interconnect activates the firmware, which takes the interconnect offline.

•You can prevent the loss of network connectivity for servers connected to a logical interconnect that has a stacking mode of Enclosure and a stacking health of Redundantly Connected by updating firmware using the following method:

1.Staging the firmware on the logical interconnect.

2.Activating the firmware for the interconnects in even-numbered enclosure bays.

3.Waiting until the firmware update to complete and the interconnects are in the

Configured state.

4.Activating the firmware for the interconnects in the odd-numbered enclosure bays.

Networks

•If you attempt to delete a network that is in use by one or more server profiles, the appliance warns you that the network is in use. If you delete the network while it is in use, server profile connections that specify the network explicitly (instead of as part of a network set) are taken offline.

If you add a network with the same name as the network you deleted, connections that specify the network explicitly (instead of as part of a network set) are not updated—you must edit
