4. When the IRF links fail, the system outputs error messages for detecting multi-active devices and
prompts you to repair the links.
%May 6 15:10:05:477 2010 HP MAD/1/MAD_COLLISION_DETECTED: Multi-active devices
detected, please fix it.
Because the member ID of Device B is 2, when the MAD mechanism detects errors, the state of Device
B changes to recovery and all ports on Device B except for the reserved ones are shut down.
# Repair IRF links. Then, you are prompted that an IRF fabric merge will happen and you need to reboot
the IRF fabric.
%May 6 15:12:52:935 2010 HP STM/6/STM_LINK_STATUS_UP:
IRF port 1 is up.
%May 6 15:13:02:828 2010 HP STM/4/STM_MERGE_NEED_REBOOT:
IRF merge occurs and the IRF system needs a reboot.
# Log in to the console port of Device B and reboot the device.
<Sysname> reboot
