HPE FF 5700 - No Powers or Fan found

[jmbredal]

NAV doesn't find any powers or fans for a HPE FlexFabric 5700 switch.

The SNMP query's are the following:

FAN1:
ENTITY-MIB::entPhysicalClass.116 = INTEGER: fan(7)
FAN2:
ENTITY-MIB::entPhysicalClass.117 = INTEGER: fan(7)

PSU1:
ENTITY-MIB::entPhysicalClass.113 = INTEGER: powerSupply(6)
PSU2:
We don't have this installed yet, so don't know if it's .114.

We need to have alarm set if some of these fails.

@soderholmm: If the PSUs and fans are present in the ENTITY-MIB, NAV should really find them. Does the ipdevpoll inventory job finish successfully on this switch?

Also, NAV cannot detect the status of the PSUs on HP unless it supports HP's proprietary POWERSUPPLY-MIB. There's a copy of it here: https://raw.githubusercontent.com/pgmillon/observium/master/mibs/hp/POWERSUPPLY-MIB

If you have the MIB file installed, you can try

snmptable -Ci -v2c -c <community> <yourswitch> POWERSUPPLY-MIB::hpicfPsTable

The output might look like this:

SNMP table: POWERSUPPLY-MIB::hpicfPsTable

For fans, there is also HP's FAN-MIB: https://raw.githubusercontent.com/pgmillon/observium/master/mibs/hp/FAN-MIB

The table in question is FAN-MIB::hpicfFanTable

[soderholmm]

I have now installed the MIBS + HP-ICF-OID and tried them.
The results are:
FAN-MIB::hpicfFanTable: No entries
POWERSUPPLY-MIB::hpicfPsTable: No entries

And the log from inventory says:
[INFO schedule.netboxjobscheduler] [inventory ] inventory for completed in 0:00:49.943490. next run in 5:59:10.056587.

If I query ENTITY-MIB::entPhysicalTable the PSU:s (113 and 114) and FAN:s (116 and 117) are there.
Also the serial numbers are listed.

And now PSU or FAN is found in NAV.

[lunkwill42]

Still strange they didn't appear in NAV before. I do want to stress that you will not get status updates for these PSUs and FANs if those proprietary MIBs have no entries :-(

[soderholmm]

Sorry, I was misspelling NO to NOW. NAV have not found any PSU or FAN yet.

[lunkwill42]

@soderholmm, could you set DEBUG level logging for nav.ipdevpoll.plugins.psu in logging.conf and rerun the ipdevpoll inventory job for your HP switch, to see what is logged?

[soderholmm]

This is what I get: [INFO nav.ipdevpoll] --- Starting ipdevpolld inventory --- [INFO plugins] Imported 29 plugin classes, 29 classes in plugin registry [INFO nav.ipdevpoll] Running single 'inventory' job for <IP> [DEBUG plugins.psu.powersupplyunit] [inventory <IP>] Collecting PSUs and FANs [DEBUG plugins.psu.powersupplyunit] [inventory <IP>] PSU:FAN: {'entPhysicalSoftwareRev': '', 'entPhysicalHardwareRev': '', 'entPhysicalParentRelPos': 1, 0: 114, 'entPhysicalClass': 'powerSupply', 'entPhysicalName': 'PSU 2', 'entPhysicalContainedIn': 14, 'entPhysicalSerialNum': 'CN58GN70RT', 'entPhysicalDescr': 'PSU', 'entPhysicalFirmwareRev': '', 'entPhysicalIsFRU': True, 'entPhysicalModelName': ''} [DEBUG plugins.psu.powersupplyunit] [inventory <IP>] PSU:FAN: {'entPhysicalSoftwareRev': '', 'entPhysicalHardwareRev': '', 'entPhysicalParentRelPos': 1, 0: 113, 'entPhysicalClass': 'powerSupply', 'entPhysicalName': 'PSU 1', 'entPhysicalContainedIn': 13, 'entPhysicalSerialNum': 'CN5AGN7092', 'entPhysicalDescr': 'PSU', 'entPhysicalFirmwareRev': '', 'entPhysicalIsFRU': True, 'entPhysicalModelName': ''} [DEBUG plugins.psu.powersupplyunit] [inventory <IP>] PSU:FAN: {'entPhysicalSoftwareRev': '', 'entPhysicalHardwareRev': '', 'entPhysicalParentRelPos': 1, 0: 116, 'entPhysicalClass': 'fan', 'entPhysicalName': 'FAN 1', 'entPhysicalContainedIn': 16, 'entPhysicalSerialNum': 'CN50FDF414', 'entPhysicalDescr': 'FAN UNIT', 'entPhysicalFirmwareRev': '', 'entPhysicalIsFRU': True, 'entPhysicalModelName': ''} [DEBUG plugins.psu.powersupplyunit] [inventory <IP>] PSU:FAN: {'entPhysicalSoftwareRev': '', 'entPhysicalHardwareRev': '', 'entPhysicalParentRelPos': 1, 0: 117, 'entPhysicalClass': 'fan', 'entPhysicalName': 'FAN 2', 'entPhysicalContainedIn': 17, 'entPhysicalSerialNum': 'CN50FDF44J', 'entPhysicalDescr': 'FAN UNIT', 'entPhysicalFirmwareRev': '', 'entPhysicalIsFRU': True, 'entPhysicalModelName': ''}

Thanks, @soderholmm. Looking at the code now, I realize that, although the plugin can see these PSUs and FANs in the ENTITY-MIB, it doesn't store them into NAV when there is no corresponding MIB support to monitor their status.

I guess there are two questions:

1. Should NAV bother to register FANs and PSUs when there is no way to know their status?
2. Why doesn't your HP switch support HP's own MIB to get PSU and fan status? Are you up-to-date with the latest software?

[soderholmm]

Well, this is not "normal" HP switches. It's H3C switches with some other OS/Firmware than HP's own switches. Maybe that's why they don't have HP MIBS, but the firmware is now 2 years old on our switches too. I guess maybe we have to go for option 1 then or someone have to invest some time to find witch H3C MIBS has the status information.

[lunkwill42]

Looks like there's a typo-ridden MIB available from various sources:

HH3C-REDUNDANCY-POWER-MIB

I don't see a clear way of associating the contents of these tables with the contents of ENTITY-MIB::entPhysicalTable, but you could see if you are able to use this MIB to get some sensible output from your switches.

Closing, due to lack of feedback.
