Answer

E-Series default management port IP behavior:

E-Series controllers ship with DHCP enabled by default. If a controller is unable to obtain a DHCP address on a given network port, it will revert to a default static IP address. This process can take up to 3 minutes.

Default static IP addresses are not persisted across link down events when a network port on a controller is set to use DHCP. If a port is configured for DHCP the controller will attempt to obtain a DHCP address on every link up event, including cable insertions, reboots, and power cycles. Any time a DHCP attempt fails, the default static IP address for that port will be used. 

When using DHCP, the recommendation is to use a permanent DHCP lease.

When using static IP addresses it is recommended to set a static IP using SANtricity. Once a static IP is configured, it will persist through all link down/up events.

NOTE: After changing the management IP address, the SANtricity management software might be unable to connect to the storage array. Remove the storage array from the Enterprise Management window and then add it again.

 

Default IP addresses for all platforms except EF600 running 11.60 or earlier:

Controller 1 (port 1):  IP Address : 192.168.128.101
Controller 1 (port 2):  IP Address : 192.168.129.101*
Controller 2 (port 1):  IP Address : 192.168.128.102
Controller 2 (port 2):  IP Address : 192.168.129.102*

 

Default IP addresses for all platforms running 11.60.2 and later, or EF600 running 11.60 or later:

Controller 1 (port 1):  IP Address : 169.254.128.101
Controller 1 (port 2):  IP Address : 169.254.129.101*
Controller 2 (port 1):  IP Address : 169.254.128.102
Controller 2 (port 2):  IP Address : 169.254.129.102*

 

*Port 2 on the controllers should be reserved for Customer Support usage, the default network settings of DHCP enabled should not be changed.
