GLYPH<SM590000> 192.168.10.12 ( Cluster IP address): – https://192.168.10.12/service  opens Service Assistant Tool for configuration node. – https://192.168.10.12  opens the cluster management GUI. Note:  Canisters are named Canister 1 (view from rear left side) and Canister 2 (view from  rear right side). The  logical names  for canisters ( node name )  in the Service Assistant Tool  are  node1  and  node2 .  Which is  node1  and which is  node2  depends on the actual configuration and in which order  the controllers were added to the cluster. If Canister 2 was added first, it is assigned the  logical name  node1 . Therefore, no direct relation exists between the canister number and  node number. The login window of FlashSystem 900 Service Assistant Tool allows only the superuser to log  in; therefore, the user name cannot be changed.
