What does this mean: "SATP VMW_SATP_LOCAL does not support device configuration"?

  • 772

Can anyone tell me what this means in ESXi 5.1?:

SATP VMW_SATP_LOCAL does not support device configuration

I've googled it and I get a lot of results, but as yet all the pages that contain the string are discussing other matters.

The storage array is a HDS HUS-VM and the hosts are HP b460c G8 blades with flex fabric and flex fabric VCs which I am in the process of commissioning and would like to get it started on the right foot - i.e. error and warning free!

As requested a description of our cabling:

HUS-VM with 16 ports CL1A CL3A CL5A CL7A CL1B CL3B CL5B CL7B CL2A CL4A CL6A CL8A CL2B CL4B CL6B CL8B.

There are two SAN fabrics, A and B. Ports with the suffix A are on SAN A, ports with the suffix B are on SANB. I.e.

The Flex Fabric module in interconnect bay 1 (left hand side as you face the rear) is patched into n FC switch on SAN A, via local ports X1,X2,X3.

The Flex Fabric module in interconnect bay 2 (right hand side as you face the rear) is patched into n FC switch on SAN B, via local ports X1,X2,X3.

The ESXi blade has two FCOE (FlexFabric) ports Port 1 is on mapped to port 2 on the FF module in interconnect bay 1 (SAN A). Port 2 is on mapped to port 2 on the FF module in interconnect bay 2 (SAN B).

There is a zone configured with port 1A and Port 1 on the blade. There is a zone configured with port 2A and Port 2 on the blade.

  1. This is happening because you have more than one path to the same disk, but ESXi doesn't support that using LOCAL. ESXi only supports other methods such as ALUA.

    If your array supports ALUA (for instance), you can manually tell ESXi just that:

    esxcli nmp satp addrule --satp="VMW_SATP_ALUA" --vendor="SCST_BIO" --model="^r*" \
   --description="SCST with ALUA support" --claim-option=tpgs_on

    Where model= is regex of the SCSI model name, and vendor would be, in your case, HITACHI.

    Then the simple way to get it to apply is to reboot.
