It appears that only with Firmware Version V10L47-0000, a Fujitsu
Eternus DX90 S2 will fully utilize VAAI (Details available in Fujitsu
Support document SB-STO-13023).
After upgrading to that firmware version we are observing enjoyable
high throughput with VAAI operations (up to 900 MB/s).
We are only somewhat bothered that vmkernel.log on the ESXi 5.1 server
reports about 2500 lines of Warnings, some even Errors, e.g.
...NMP: nmp_ThrottleLogForDevice:2319: Cmd 0x83 (0x4124801cbe80, 17670) to dev "naa.6000000d10e100000112105c00000000" on path "vmhba4:C0:T0:L1" Failed: H:0x7 D:0x0 P:0x0 Possible sense data: 0x0 0x0 0x0. Act:EVAL

...<3>lpfc820 0000:0c:00.1: 1:(0):0717 FCP command x83 residual underrun converted to error Data: x6c x6c x6c
Can we savely errors like H:0x7 ()
Now VMWare support says this is a HBA issue:
...
We can see here from the analysis of one of the error codes (this one
came direct from storage, as it was a D:0x2):
H:0x0 D:0x2 P:0x0 Valid sense data: 0xa 0xd 0x1
This means, basically:
Indicates an EXTENDED COPY command was aborted due to an error
condition on the source device. the destination device. or both.
However, there are H:0x7 failures, which usually definitely indicate a
host adapter issue.
...
HP support says they do not check HP adapter / Fujitsu storage
interoperability, and Fujitsu should be asked.
Fujitsu support says it is not an issue with their storage.
betwixed and between ...
Has someone made similar observations?
