You are planning to update your running switch environment. You need to determine if certain
conditions exist before the FASTPATH software and reference configuration file (RCF) on a
NetApp CN16xx cluster switch can be installed.
Which condition must exist in this scenario?

A.
You must set the port configuration to default for all ports before running the portcfgdefault portnumber command.

B.
The cluster must be a fully functioning cluster (no error log messages or other issues).

C.
All ISL ports must be moved to a different switch.

D.
You can only update your switch environment within offline windows.

Explanation:
The following conditions must exist before installing the FASTPATH software and
reference configuration file (RCF) on a
NetApp CN16xx cluster switch:
* The cluster must be a fully functioning cluster.
* There must be no defective cluster NICs and all connected ports on both cluster switches must
be functional.
*All cluster ports must be up.
* All cluster logical interfaces (LIFs) must be up and must not have been migrated.
* The Data ONTAP (privilege: advanced) cluster ping-cluster -node node1 command must indicate
that larger
than PMTU communication is successful on all paths.
* You must consult the switch compatibility table on the NetApp CN1601 and CN1610 Switches
page for the supported
FASTPATH, RCF, and Data ONTAP versions. T Installing FASTPATH software and RCF files on NetApp Cluster switches, page 1
