Recovering An Irf Fabric - HP 5900 Series Configuration Manual

Recovering an IRF fabric

When the failed IRF link between two split IRF fabrics is recovered, all member devices in the
Recovery-state fabric automatically join the Active-state fabric as subordinate members, and the network
ports that have been shut down by MAD automatically restore their original physical state, as shown
in Figure 12.
Figure 12 Recovering the IRF fabric
If the Active-state fabric has failed, for example, because of device or link failures, before the IRF link is
recovered (see Figure 13), use the mad restore command on the Recovery-state fabric to change its state
to Active to take over. After you repair the IRF link, the two parts merge into a unified IRF fabric.
