Issue

During ONTAP upgrade, BMC is not reachable and the system shows SP duplicate IP alerts (sp.dup.ip):

[node1: spmgrd: sp.dup.ip:error]: SP IP address 10.x.x.x in use by another system.

[node1: spmgrd: sp.dup.ip:error]: SP IP address 10.x.x.x in use by another system.

[node1: spmgrd: sp.dup.ip:error]: SP IP address 10.x.x.x in use by another system.

No duplicate IP address is found in the network
After ONTAP upgrade, the sp.dup.ip alerts remain
The issue can also occur after a BMC firmware update or after a BMC reboot
BMC might reboot with a "HW watchdog timeout happened last time!" error and then reports the duplicate IP address:
