Scenario

You want to create a high-availability (HA) cluster with external storage devices connected to the NAS devices. The external storage devices are identical between the two devices and are connected to the same ports or PCIe slots. However, when you try to create an HA cluster in High Availability Manager, the application fails to pair the NAS devices and indicates that they are inconsistent with each other.

Cause

Assuming the two NAS devices are consistent and compatible in all other aspects, HA pairing could fail if you connected the external storage devices to the NAS devices in different chronological orders. This would cause the corresponding external storage devices to have different enclosure IDs between the two NAS devices.

Enclosure IDs are typically assigned to external devices starting from "1", based on the chronological order in which they are connected to the NAS. If the corresponding external storage devices have different enclosure IDs between the two NAS devices, High Availability Manager will consider the two NAS devices to be inconsistent.

Solution

Check if the enclosure IDs are inconsistent between the two NAS devices.
On each NAS device, go to Storage Manager > Disks > Device to check the enclosure IDs of all external storage devices.
Note
If the enclosure IDs of the external storage devices are all consistent between the two NAS devices, the HA pairing likely failed due to some other inconsistency or incompatibility issue. Please check High Availability Manager for details to resolve the issue.
Reinitialize the enclosure IDs on both NAS devices.
1. For each pair of corresponding external storage devices between the two NAS devices, ensure the external storage devices are connected to the same port or PCIe slot.
2. On each NAS device, go to Storage Manager > Disks > Device.
3. Click > Recover > Reinitialize Enclosure IDs.
  This action resets all enclosure IDs and assigns each external storage device a new ID number starting from "1", based on the order of the ports and PCIe slots that the external storage devices are physically connected to.
Ensure the enclosure IDs are consistent.
On each NAS device, go to Storage Manager > Disks > Device to check the enclosure IDs of the external storage devices. Ensure they are consistent between the two NAS devices.

You can now try pairing the NAS devices in the cluster creation wizard in High Availability Manager.

Scenario

Du ønsker at oprette en høj tilgængelighed (HA) Klynge med eksterne Lager enheder tilsluttet NAS-enhederne. De eksterne Lager enheder er identiske mellem de to enheder og er tilsluttet de samme porte eller PCIe slots. Men når du forsøger at oprette en HA Klynge i High Availability Manager, mislykkes applikationen med at parre NAS-enhederne og angiver, at de er inkonsistente med hinanden.

Årsag

Hvis de to NAS-enheder antages at være konsistente og kompatible i alle andre aspekter, kan HA-parringen mislykkes, hvis du har tilsluttet de eksterne Lager enheder til NAS-enhederne i forskellige kronologiske rækkefølger. Dette ville medføre, at de tilsvarende eksterne Lager enheder har forskellige kabinet-ID'er mellem de to NAS-enheder.

Kabinet-ID'er tildeles typisk til Ekstern enhed startende fra "1", baseret på den kronologiske rækkefølge, hvori de er tilsluttet NAS'en. Hvis de tilsvarende eksterne Lager enheder har forskellige kabinet-ID'er mellem de to NAS-enheder, vil High Availability Manager betragte de to NAS-enheder som inkonsistente.

Løsning

Kontroller, om kabinet-ID'erne er inkonsistente mellem de to NAS-enheder.
På hver NAS-enhed, gå til Lager Manager > Diske > Enhed for at kontrollere kabinet-ID'erne for alle eksterne Lager enheder.
Bemærk
Hvis kabinet-ID'erne for de eksterne Lager enheder er alle konsistente mellem de to NAS-enheder, mislykkedes HA-parringen sandsynligvis på grund af en anden inkonsistens eller inkompatibilitetsproblem. Venligst kontroller High Availability Manager for detaljer for at løse problemet.
Geninitialiser kabinet-ID'erne på begge NAS-enheder.
1. For hvert par af tilsvarende eksterne Lager enheder mellem de to NAS-enheder, sørg for, at de eksterne Lager enheder er tilsluttet den samme port eller PCIe slot.
2. På hver NAS-enhed, gå tilLager Manager > Diske > Enhed.
3. Klik på > Gendan > Initialiser kabinet-ID'er igen.
  Denne handling nulstiller alle kabinet-ID'er og tildeler hver ekstern Lager enhed et nyt ID-nummer startende fra "1", baseret på rækkefølgen af portene og PCIe-slots, som de eksterne Lager enheder er fysisk forbundet til.
Sørg for, at kabinet-ID'erne er konsistente.
På hver NAS-enhed, gå til Lager Manager > Diske > Enhed for at kontrollere kabinet-ID'erne for de eksterne Lager enheder. Sørg for, at de er konsistente mellem de to NAS-enheder.

Du kan nu prøve at parre NAS-enhederne i Klynge oprettelsesguiden i High Availability Manager.
