Symptoms

• Cannot format a new LUN in ESXi 5.x
• Formatting a LUN with the VMFS 5 filesystem fails
• When formatting the LUN through the vSphere Client via the Add Storage wizard, you see the error:
  
  "Call "HostDatastoreSystem.QueryVmfsDatastoreCreateOptions" for object "datastoreSystem-xx" on vCenter Server "hostname" failed."
  
  
• In the /var/log/hostd.log file, you see errors similar to:

Cause

This issue occurs if the LUN is not blank and contains an unsupported disk label type of AIX, which prevents the host from obtaining information about its properties.

Resolution

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.
