bl685g7, emulex NC551m, esxi 4.1: iscsi chap settings are failing with IMA_VMW_SetMutualAuthParms

I have a bl685 g7 set up with the latest esxi 4.1 from hp (4.1 U2 from June).

The latest emules drivers are already included with the image:


/sbin # esxupdate query --v | grep be2
cross_oem-vmware-esx-drivers-net-be2net_400.4.1.334.0-1vmw.2.17.249663 installed 2012-05-16T20:41:30.828723+00:00
cross_oem-vmware-esx-drivers-scsi-be2iscsi_400.4.1.334.301-1vmw.0.0.343171 installed 2012-05-16T20:46:37.652539+00:00
cross_oem-vmware-esx-ima-be2iscsi_400.4.1.334.301-1vmw.0.0.343171 installed 2012-05-16T20:50:15.749832+00:00

 
The iscsi hardware hba (emulex NC551m) supports the following 2 authentication methods:

/sbin # vmkiscsi-tool -A -l vmhba3
---------------Inititator Authentication ------------
Supported Authentication Methods for Adapter vmhba3:
IMA_AUTHMETHOD_NONE
IMA_AUTHMETHOD_CHAP


---------------Mutual Authentication ------------
Supported Authentication Methods for Adapter vmhba3:
IMA_AUTHMETHOD_NONE
IMA_AUTHMETHOD_CHAP

 

 
Using vcenter to configure chap settings for the hbas (on any level, hba, server, target) there are 2 settings available:

Do not use CHAP" maps nicely to "IMA_AUTHMETHOD_NONE" and this setting works.

 

However using the 2nd option, "Use CHAP unless prohibited by target" fails with the following error:

 

Call "HostStorageSystem.UpdateInternetScsiAuthenticationProperties" for object "storageSystem" on ESXi "10.10.10.1" failed.
Operation failed, diagnostics report: iScsiLibException: status(c0000000): Invalid parameter; Message= IMA_VMW_SetMutualAuthParms

 
So for me it seems like the setting "Use CHAP unless prohibited by target" does not map to the hba supported option "IMA_AUTHMETHOD_CHAP" which IHO should be rather something like "Use CHAP" in the vcenter config dialog?

 

Same experience with esxi 5.*.

 

???
