Replacement requirements
Before replacing the switch, make sure the following conditions are met in the current environment and on the replacement switch.
Existing cluster and network infrastructure
Make sure that:
-
The existing cluster is verified as completely functional, with at least one fully connected cluster switch.
-
All cluster ports are up.
-
All cluster logical interfaces (LIFs) are administratively and operationally up and on their home ports.
-
The ONTAP
cluster ping-cluster -node node1
command must indicate that the settings,basic connectivity
andlarger than PMTU communication
, are successful on all paths.
BES-53248 replacement cluster switch
Make sure that:
-
Management network connectivity on the replacement switch is functional.
-
Console access to the replacement switch is in place.
-
The node connections are ports 0/1 through 0/16 with default licensing.
-
All Inter-Switch Link (ISL) ports are disabled on ports 0/55 and 0/56.
-
The desired reference configuration file (RCF) and EFOS operating system switch image are loaded onto the switch.
-
Initial customization of the switch is complete, as detailed in Configure the BES-53248 cluster switch.
Any previous site customizations, such as STP, SNMP, and SSH, are copied to the new switch.
Enable console logging
NetApp strongly recommends that you enable console logging on the devices that you are using and take the following actions when replacing your switch:
-
Leave AutoSupport enabled during maintenance.
-
Trigger a maintenance AutoSupport before and after maintenance to disable case creation for the duration of the maintenance. See this Knowledge Base article SU92: How to suppress automatic case creation during scheduled maintenance windows for further details.
-
Enable session logging for any CLI sessions. For instructions on how to enable session logging, review the "Logging Session Output" section in this Knowledge Base article How to configure PuTTY for optimal connectivity to ONTAP systems.
