8.7.3 Lrack1: rack_config.json file
This file on lrack1 is required for software upgrades and connectivity checks. With a spine switch installed, this
file will contain entries for all 32 IPu-M2000s in the IPU-POD
128
, as shown in the code example below. If there
is no spine switch, this file will only contain entries for lrack1 IPU-M2000s and a similar
rack_config.json
file
on lrack2, containing entries for lrack2 IPU-M2000s, will be required for RNIC connectivity checks on lrack2
IPU-M2000s.
