scsi errors in log

Hallo,
I have set up a simple iSCSI target for vmware ESX using 2 nics with RR mpio.
I used the recommended settings for ESX iSCSI initiator found in this message board.

It works fine but in the logs I get 2 errors repeating every few minutes:

SscScsi_InquiryHandler: INQUIRY VPD page 0xb0 is not supported!

ImageFile_ScsiExec: WRITE_SAME (0x93) is not supported.

What is the problem? I want to fix these errors before going to production with this iscsi target.

Thank you!

Logging mechanism is for developers to get feedback from customers it's not for customers. So don't try to interpret the meanings of log messages and "fix" anything.

P.S. In your particular case ESXi is trying to query do we support VAAI and send VAAI related commands (WRITE_SAME). In the V6 branch VAAI is disabled due to some collisions.
We'll turn it back on in upcoming V8 branch (beta release is pending). But in any case VAAI is *acceleration* and not mandatory code path.
