The second IPMI poll of a BMC in the same worker process failed with
"'<' not supported between instances of 'float' and 'NoneType'".
pyghmi files a session in Session.initting_sessions under the
credentials as str and deletes it only under bytes, so the entry stays
and the next Command got the old, logged-out session back. The driver
drops that entry itself before open() and after close(). Reproduced and
verified live against the Supermicro X10DRL-i: three polls in one
process now succeed.
IpmiDriver and RedfishDriver mix in HealthMetricsMixin, so netOrk's
SNMP health poll reads the BMC's own load, memory and interfaces where
the BMC runs net-snmp with the UCD-MIB, as the X10's does.
A Supermicro X10DRL-i refuses Redfish without a license (SUM, DCMS or
OOB), even the service root. IPMI answers without one.
- New entry point `ipmi` (napalm_redfish.ipmi.IpmiDriver) on
ManagementControllerDriver, over pyghmi: facts and inventory from the
FRU (serial number, system UUID), the BMC's LAN interface, sensors
(temperatures, fans, power supplies), the power state, the event log
and the BMC firmware. Read-only: no power control, no BMC reset.
Tested against recordings of the X10 with serials, the UUID, MACs and
IPs replaced.
- RedfishDriver.open() no longer fails on a license refusal: get_facts
returns what is known without Redfish, get_device_warnings reports
bmc_license_required with the licenses the BMC names, every other
getter raises. netOrk then shows the reason instead of an offline BMC.
- IpmiDriver is not exported from the package: NAPALM's own
get_network_driver("redfish") takes the first driver class of
napalm_redfish.
One Redfish answer (the service root or the error a service refuses it
with) and one landing page (Supermicro/ATEN, iDRAC or iLO) can match,
never all of them. Grouped, the driver's maximum in netOrk's discovery
is 21 instead of 41, and a Supermicro landing page alone (6 of 21)
outranks the "linux" its BMC reports over SNMP (5 of 18).
Requires napalm-device-types 4.8 for FingerprintRule.group.
netOrk's discovery took six switches for BMCs: the PortSpec for 443
added 5 points to every device with a web UI, and nothing else scored
them. The port now carries no weight.
The real BMC, a Supermicro X10DRL-i, was not recognised at all. Its web
UI (ATEN firmware) gets a rule, as do iDRAC and iLO; discovery fetches
those landing pages today. A rule for a Redfish error body covers the
service root once discovery reads it.
That board refuses Redfish without a Supermicro license, even the
service root (403 OemLicenseNotPassed, "SUM DCMS OOB"). The library
reports only the status, so open() reads the error body once more and
raises RedfishLicenseError naming the licenses.
Release 0.1.1.
