XtremIO: Så här flyttas ett XtremIO-kluster med inbyggd replikering till en annan XMS

Sammanfattning: Ibland är det nödvändigt att flytta ett XtremIO-kluster från ett XMS till ett annat. Vanligtvis är den här åtgärden enkel och utförs genom att ta bort klustret från det aktuella XMS-systemet och lägga till det i ett nytt XMS med hjälp av XMCLI-kommandon. Om XtremIO-klustret är inblandat i inbyggd fjärreplikering krävs dock några ytterligare steg för att bevara klusterreplikeringsstatusen. ...

Instruktioner

  1. Exempelkonfiguration
För att hjälpa till med proceduren använder vi följande exempel:
  • Initial XtremIO Native Replication-källa XMS och kluster: vxms-xbrickdrm918/xbrickdrm918
  • Initialt XtremIO inbyggt replikeringsmål XMS och kluster: vxms-xbrickdrm919/xbrickdrm919
  • Nytt XMS-system: vxms-xbrickdrm912
  1. Målet med proceduren
Målet i vårt exempel är att flytta XtremIO-källklustret xbrickdrm918från vxms-xbrickdrm918 till vxms-xbrickdrm912.
  1. Procedur

Följande är den process som ska följas för att flytta XtremIO-kluster med inbyggd replikering till ett annat XMS.

  1. Kontrollera den befintliga replikeringskonfigurationen och statusen.

  1. Lägg till det nya XMS.

Lägg till den nya XMS i fjärrskyddsdomänen för det lokala XMS-systemet. I det här exemplet lägger vi till vxms-xbrickdrm912 till vxms-xbrickdrm919.

xmcli (admin)> add-remote-protection-peer-xms remote-ip-addr="10.225.65.zzz" remote-user-password="xxxxxxxx" remote-xms-user="admin" remote-xms-alias-name="xbrickdrm912"

  1. Ta bort klustret från befintligt XMS.
I det här fallet tar vi bort klustret xbrickdrm918 från vxms-xbrickdrm918 XMS. 
xmcli (admin)> remove-cluster cluster-id=1 cluster-psnt="XXXXXXXXXXXXXXX" 
Are you sure you want to remove cluster xbrickdrm918 [1]? (Yes/No): Please enter either Yes or No: yes [###################################################] 100%        (elapsed time 00:00:15) Cluster xbrickdrm918 [1] removed successfully
  1. Ta bort den ursprungliga XMS-filen från replikeringsdomänen. 

I det här exemplet tar vi bort den ursprungliga vxms-xbrickdrm918 XMS från XMS på fjärrskyddsdomänen vxms-xbrickdrm919 .

xmcli (admin)> remove-remote-protection-peer-xms xms-alias-name="vxms-xbrickdrm918"
XMS was removed from RM Domain

  1. Lägg till kluster till nytt XMS.

Vi använder följande kommando för att lägga till xbrickdrm918-kluster i vxms-xbrickdrm912 XMS.

xmcli (admin)> add-cluster sc-mgr-host="10.139.88.ccc"
20:26:23 - Collecting cluster information
20:26:38 - Loading data from cluster
Clusters added successfully
  1. Bekräfta att flytten har slutförts.
    1. Vänta i 5 minuter och kontrollera sedan replikeringssessioner och IP-länkstatusar från båda XMS. 
    2. Kontrollera status från vxms-xbrickdrm919.

  1. Kör HCS-skriptet för att bekräfta hälsostatusen för båda klustren.

Obs! Kör som alltid HCS-skript på båda XMS-systemen för att bekräfta.
