- Enable SSH service on ALL ESX at startup
- Stop all VM from VCenter
Always stop the Active Directory and VCenter at last !
Before stopping AD and VCenter check on which ESX they are active, because you will connect to the ESX directly to activate them.
- Unmap disks from PRODUCTION storage
- switch the disks to DR site (go to replication and switch the consistency group)
- Map disks from DR to all ESX
Never map both PRODUCTION and DR disks together on ESX, else ESX will see the same signature on multiple disks
- reboot ALL ESX servers
- Connect to each ESX using Vsphere client
- Connect to the ESX servers using SSH, and check the VMFS, if not reconnized
Mount each VMFS using < -n> option for non-persistent (if reboot, you need to replay this step)
The ESXi Shell can be disabled by an administrative user. See the vSphere Security documentation for more information. ~ # esxcli storage core adapter rescan --all ~ # esxcli storage vmfs snapshot list 4e0adf0c-cefffef9-5203-00101886766c Volume Name: VMFS2 VMFS UUID: 4e0adf0c-cefffef9-5203-00101886766c Can mount: true Reason for un-mountability: Can resignature: false Reason for non-resignaturability: the volume is being actively used Unresolved Extent Count: 1 ~ # esxcli storage vmfs snapshot mount -n -l "VMFS2"
- Once ALL VMFS mounted on all ESX, connect to VIclient and start first the Active Directory, once booted, start the VCenter
- Then connect to Vcenter and start ALL VMs
- Enable SSH service on ALL ESX at startup
- Stop all VM from VCenter
Always stop the Active Directory and VCenter at last !
Before stopping AD and VCenter check on which ESX they are active, because you will connect to the ESX directly to activate them.
- Unmap disks from DR storage
- switch the disks back to PRODUCTION site (go to replication and switch the consistency group)
- Map disks from PRODUCTION to all ESX
- reboot ALL ESX servers
- Connect to each ESX using Vsphere client, all VMFS should be ready for use
- Once ALL VMFS mounted on all ESX, connect to VIclient and start first the Active Directory, once booted, start the VCenter
- Then connect to Vcenter and start ALL VMs
