To work around this issue, either zero-out the LUN from the storage array or apply a compatible disk label type using the
partedUtil command on the ESXi host. Applying a legacy MBR (msdos) or GTP type disk label to the LUN allows it to be used in conjunction with the Add Storage Wizard.
Warning: This procedure has the potential to cause data loss if it is applied against the incorrect LUN. Ensure to validate that you have the correct NAA identifier before proceeding. For more information, see
Identifying disks when working with VMware ESX/ESXi (1014953).
To apply a legacy msdos type partition label, run this command:
# partedUtil mklabel /dev/disks/naa_id msdos For example:
# partedUtil mklabel /dev/disks/naa.60060480000190103951533030311234 msdos
After running this command, the partition table must be able to be read using this command:
# partedUtil getptbl /vmfs/devices/disks/naa_id
You must now be able to format the LUN using the Add Storage Wizard from the vSphere Client.
