Thanks for the update Kris.


It appears that the link isn't accessible.


Same for me. Link isn't reachable.


I have been told that 6.3.1 has been pulled due to bugs.  No further details available to me as a customer...

Hope it helps



HI Brendon,

The release was pulled due issues with snapmirror and hyper-v lun enumeration.

1) SDW 6.3.1 does not recognize SnapMirror relationship for LUNs in a Qtree

2) SDW 6.3.1 does not enumerate Hyper-V shared LUNs ina non-CSV (Clustered Shared Volume) configuration.

Recommendation: If you have already installed SDW 6.3.1 and are having issues with these specific issues then customers are advised to downgrade to SD 6.3P2.

For all other situations:  SDW 6.2.1 is GA and SDW 6.3 is FCS and available on the NOW site.


Any updates on this?  We are running MS FCS in HyperV using CSV's.  We are on 6.3P1 and are REALLY affected by the enumeration slowness between snap drive and SMHV.  I heard a rumor that maybe there is 6.4 on the Horizon.  Please advise!




Yes, SDW 6.4 is scheduled to release this month.


Will SDW 6.4 have the improved Space Reclamaion performance / process ?


On that note - we are two months further & still no sign of 6.4 in the download section on NOW.

Any revised ETA for SDW 6.4?


Hi Radek,  SDW 6.4 just got posted and is available here -


Hi watan,

Thanks for the update - good stuff!
