Posted: Wed Mar 06, 2024 8:40 am Post subject: HPE Nimble free Datastore value not correct |
|
|
Hello,
We have noticed that the LUNs of the Nimble Storage are probably being read incorrectly by the KS host.
The test "VM Host free Datastore space" is used via an ESX host.
Currently there is still 1.36 TB of 5 TB free on LUN001. That would be 27% approx.
However, KS Host only recognizes 8% free space.
Presumably the compression and deduplication of the nimble is not taken into account here.
Are there any other ways of reading this?
Hostmon is version 14.28 on Windows Server 2022
RMA: Version: 8.10 on host: SMON02 Windows Server 2019 Build 17763
Best Regards |

Can we get MOB access (over HTTPS) to the system?

Hi Alex,
I have to clarify this with the business management.
What exactly needs to be activated here? |

If HostMonitor is able to perform the test then everything is activated.
But we need hostname/IP, username, password
>Presumably the compression and deduplication of the nimble is not taken into account here
When HostMonitor requests MOB to get free space, MOB does not provide compression and deduplication related information, at least on our system.
May be there is such information on your system, so it would be good to check

Its not Windows session, its HTTPS request, you may see it only in the logs on your firewall.

Hi Alex,
thanks for the effort
I have noticed that the datastores are read out correctly via another ESX host... for whatever reason...
We'll keep an eye on it for now and I'll get back to you if necessary.
Have a nice day. |

Hi Alex,
Access to the VCenter was rejected by the management. Since the ESX hosts can only see the "falsified" data anyway and the KS Hostmon reads it out via the MOB, this is rather unfavorable anyway since other values are available on the storage itself.
Is there a way to read the LUNs of the Nimble Storage directly without using the ESX host? I would take a look at this with a colleague. Maybe you've had something like this before?
Best regards Felix |

Such devices support SNMP, right?
So you may try SNMP Get test or Drive Free Space in SNMP mode.
Hard to say what exactly OIDs supported. HPE MIB files offer thousand counters but most of them does not work on devices we have..
May be counters from this table can be used

volSizeLow Unsigned32 Yes Max. size in MB (low order bytes).
volSizeHigh Unsigned32 Yes Max. size in MB (high order bytes).
volUsageLow Unsigned32 Yes Usage in MB (low order bytes).
volUsageHigh Unsigned32 Yes Usage in MB (high order bytes).
volReserveLow Unsigned32 Yes Reserved MB (low order bytes).
volReserveHigh Unsigned32 Yes Reserved MB (high order bytes).
If you provide SNMP access, may be we can create new tests. Same for Aruba
