RecoverPoint for VMs: Svazky žurnálu uzamčené na konkrétních hostitelích ESXi mohou vést k nedostupnosti replikace dat a regulaci restartování.

RecoverPoint for Virtual Machines používá svazky žurnálu ke sledování a správě bitových kopií k určitému bodu v čase.
V prostředí RP4VMs může dojít k problému, který uzamkne svazek deníku na jednoho hostitele ESXi.
Pokud je pár vRPA přiřazený k replikaci virtuálních počítačů přesunut pomocí vMotion na jiného hostitele ESXi, může dojít k chybě replikace dat (DRU).

To může ovlivnit všechny skupiny konzistence (CG) přiřazené ke konkrétnímu RPA, což povede ke stavu DISABLE nebo ERROR.

Může dojít k selhání procesu replikace :

replication Sun May 19 23:03:56 UTC 2024

replication Sun May 19 23:28:46 UTC 2024

Výsledkem je odpojení zařízení RecoverPoint (RPA) od clusteru.

Příčina této situace se v současné době vyšetřuje.
V současné době není k dispozici žádné trvalé řešení; Jedná se však o situaci specifickou pro RP4VMs.

Tato situace může nastat v různých scénářích:

1. Když je zařízení vRPA zodpovědné za ochranu virtuálního počítače přesunuto pomocí vRPA na jiného hostitele ESXi, jelikož původní hostitel ESXi uzamkne deník na tohoto konkrétního hostitele ESXi.

2. Když skupina konzistence přesune vlastnictví z jednoho páru vRPA do druhého, čímž dojde k vyvolání výše uvedené situace.

Usnesení:
Pro tento problém existuje řešení, ale je nutný zásah pracovníků technické podpory společnosti Dell Technologies.  Aby bylo možné tuto situaci vyřešit, je třeba shromáždit správné protokoly RP4VMs, ESXi a vCenter, které by měly být podle potřeby eskalovány. Obraťte se na středisko zákaznické podpory Dell Technologies nebo na zástupce technické podpory a uveďte ID tohoto řešení znalostní databáze Dell Technologies.
