By using DMI String as identifier, such as 'system-product-name'
or 'system-version' add support for node groups. This allow the
use of a single entry in 'NetConfigDataLookup' to match a group
of systems of the same model, vendor etc.
Try to match on ethernet mac address first, then if no match is
found 'dmiString' and 'id' is used, if the keys are set.
Example:
NetConfigDataLookup:
node1:
nic1: "00:c8:7c:e6:f0:2e"
node2:
nic1: "00:18:7d:99:0c:b6"
node3:
dmiString: 'system-version'
id: 'ThinkPad T460p'
nic1: enp0s31f6
# Dell PowerEdge R630 - nodegroup
nodegroup1:
dmiString: "system-product-name"
id: "PowerEdge R630"
nic1: em3
nic2: em1
nic3: em2
# Cisco UCS B200-M4 - nodegroup
nodegroup2:
dmiString: "system-product-name"
id: "UCSB-B200-M4"
nic1: enp7s0
nic2: enp6s0
Change-Id: Ie2547cd8805c57ed9afe7362eada802580ffc215
nic1: "00:c8:7c:e6:f0:2e"
node2:
nic1: "00:18:7d:99:0c:b6"
nic1: "00:c8:7c:e6:f0:2e"
node2:
nic1: "00:18:7d:99:0c:b6"
- This will result in the first nodeN entry where a mac matches a
- local device being written as a mapping file for os-net-config in
+ node3:
+ dmiString: 'system-uuid'
+ id: 'A8C85861-1B16-4803-8689-AFC62984F8F6'
+ nic1: em3
+ # Dell PowerEdge
+ nodegroup1:
+ dmiString: "system-product-name"
+ id: "PowerEdge R630"
+ nic1: em3
+ nic2: em1
+ nic3: em2
+ # Cisco UCS B200-M4"
+ nodegroup2:
+ dmiString: "system-product-name"
+ id: "UCSB-B200-M4"
+ nic1: enp7s0
+ nic2: enp6s0
+
+ This will result in the first node* entry where either:
+ a) a mac matches a local device
+ or b) a DMI String matches the specified id
+ being written as a mapping file for os-net-config in
