Switches must be powered on and operating. This procedure is optional if switch configurations have not changed.
Optional Task: Save management network switch configurations before removing power from cabinets or the CDU. Management switch names are listed in the /etc/hosts file.
From the command line on any NCN run:
ncn# grep 'sw-' /etc/hosts
Example output:
10.252.0.2 sw-spine-001
10.252.0.3 sw-spine-002
10.252.0.4 sw-leaf-001
On Aruba-based systems all management network switches will be Aruba and the following procedure. For each switch:
ssh to the switchwrite memory commandExample:
ncn# ssh admin@sw-spine-001.nmn
admin@sw-spine-001 password:
sw-spine-001# write memory
sw-spine-001# exit
On Dell and Mellanox based systems, all spine and any leaf switches will be Mellanox. Any Leaf-BMC and CDU switches will be Dell. The overall procedure is the same but the specifics of execution are slightly different.
ssh to the switchenable mode (Mellanox only)write memory commandMellanox example:
sw-spine-001# enable
sw-spine-001# write memory
sw-spine-001# exit
Dell example:
sw-leaf-001# write memory
sw-leaf-001# exit
Save configuration settings on Edge Router switches (Arista, Aruba or Juniper) that connect customer storage networks to the Slingshot network if these switches exist in the site and the configurations have changed. Edge switches are accessible from the ClusterStor management network and the CSM management network.
Example:
ncn# ssh admin@cls01053n00
admin@cls01053n00 password:
cls01053n00# ssh r0-100gb-sw01
r0-100gb-sw01# enable
r0-100gb-sw01# write memory
r0-100gb-sw01# exit
