how to determine if a hard disk conform to SAS V2 ie that keep an error count of its bad sectors

is there a website that list out all the various makes / models of disks / HDDs
that tells us if a hard disk conforms to this standard?  Or how do I determine
if my SAN's HDD conforms to this standard?

I was told by a storage specialist that it's not a SAN feature but a feature of
hard disk drive that keeps track how many failed attempts it has tried to
read a sector unsuccessfully.

If I provide the part number of my HP's EVA (Enterprise Virtual Array) SAN
fibre disk, is there anyway to tell if it complies to which level?

What a strange question, EVAs don't currently use SAS disks, although they're likely to in the future.

Well, last month one of our EVA4400 fibre disk had a bad sector (according to HP & there was
no alert & the EVA failed to copy out data to another disk & caused the entire EVA to fail & the
entire DB became inaccessible.  

IBM just gave us a presentation & told us that the ability to detect bad sector depends on the
feature of the HDD & not the SAN.  So if the type of HDD used in the SAN complies to certain
standard (I heard it's SAS 2 if I did not hear wrongly), we would have been able to detect it
in advance.  What's more, IBM was presenting  "predictive"-type servers which will alert us
prior to actual hardware fault surfacing, so I'm wondering what type of HDD I currently have
in my EVA4400 & I can pre-empt future such bad-sectored HDD fault.  HP applied a firmware
patch later to the EVA4400 but I'm not sure if my other EVAs would face the same issue

Thanks very much gents.

Andy, my management now thinks that I should constantly scan HP ITRC for
possible future disruptive firmware bugs & then perform the upgrade.

Is it just a simple matter for end-user IT like me to do the EVA firmware upgrades
from HP StorageWorks Command View (I suppose this must be the Windows
box which I can group/ungroup disks & configure the EVA disk pools)?

Or such firmware upgrade is best done by HP considering that I have to check
the compatibility matrix (which a storage person in HP told me was only made
available to the public last year).  

I was told by the HP storage person that the compatibility matrix checks involve
checking if my fibre switches' firmware needs to be upgraded as well & whether
the FC drivers on my servers (Linux, Windows & HP-UX) needs to be upgraded
too prior to the eventual firmware upgrade on the EVA4400 (I suppose this means
upgrading the EVA4400's SAN controller firmware).

Just 3 last questions :

1) does www.hp.com/storage/spock alert us via email as well when a new
    EVA firmware is released?  If not, does ITRC does this?

2) When I login to ITRC, I have quite some difficulty navigating to a place or
    link to sign up for email notification for EVA firmware releases.  If you can
    provide me step by step of what I need to click to get there, appreciate it.

3) I heard that firmware upgrade for HP's XP (OEM'ed from Hitachi?) SAN is
    not that simple for customers to undertake themselves, is that so?  So
    for EVA, other than the upgrade from XCS 09522000, firmware upgrades
    for EVAs are generally simple enough for customers to undertake on
    their own?  If the customer created a problem during an EVA firmware
    upgrade undertaken on their own, would HP support? (assuming the
    customer only sign up EVA hardware support with HP & no EVA software
    support)
