ONTAP 7-Mode Transition

Remounting VMFS volumes after transition using the ESXi CLI

After transition, you can use the ESXi CLI to remount your volumes and bring your datastores and VMs to their pretransition states.

The original 7-Mode LUN must be unmapped or offline.

These steps apply to volumes and spanned volumes.

Steps

  1. Log in to the ESXi console using SSH.

  2. List the newly added LUNs with existing VMFS signatures and VMFS labels:

    # esxcfg-volume -l

    The following is an example of the LUNs listed with VMFS signatures and VMFS labels.

    # esxcfg-volume -l
VMFS UUID/label: 53578567-5b5c363e-21bb-001ec9d631cb/datastore1
Can mount: Yes
Can resignature: Yes
Extent name: naa.600a098054314c6c445d446f79716475:1 range: 0 - 409599
(MB)

  3. Remount the VMFS volumes persistently with the same signature:

    • For regular volumes:
      esxcfg-volume -M|--persistent-mount VMFS UUID|label

    • For spanned volumes:
      # esxcfg-volume -M vmfs-span-ds
