Hey there, I welcome questions. Unfortunately, my answers may not be sufficient to satisfy your mental hunger.
To be honest, I don't know exactly what the D8 does.
I was informed that it fixes the snapmirror code. The error was found to occur only in our "specific" circumstance.
So what was/is our circumstance?
1) F880 source snapmirroring 3 batch area volumes to an F820 target across a 20Mbit Ethernet WAN. 2) The amount of data change per day is high. Approximately 10-40Gb per volume. 3) We were experiencing poor throughput across the WAN link (carrier issue) and had to frequently abort the snapmirror and delete snapshots from the F880 source in order to prevent snapshot space over-running production data space. This throughput has since been addressed (before D8). 4) The F820 target panicked a couple of times and dumped to the ok prompt. One of the target volumes was found to be corrupt. It was difficult to say if the source filer caused it or the target filer developed the corruption independently. We had some cases open and ran wafl checks and scans on both filers as a result. No errors were turned up. 5) The crash dump file was ftp'd to NetApp. This lead to the 6.3.1D8 debug release.
When I get some more time, I might read into it a bit further. For now, I am more than happy that they have addressed the issue and fixed it very quickly. We have not had any problems with 6.3.1 or the D8 releases.
Thanks, Aaron

What does the D8 fix for snapmirror? Inquiring minds want to know. ;) C-

We are running 6.3.1 on one filer (F880) and 6.3.1D8 (debug release for a snapmirror problem we were having) on another (F820). 2 others still
running
6.2.2 I believe.
As far as I know, all new F960s being shipped have 6.3.1 on them.
So overall, I have to say I recommend it. If you are snapmirroring, make sure you put 6.3.1D8 on your destination filer, that is the advice from
our
NetApp representative.

Hi, I have a F720 currently running on Data ONTAP 6.1.2R2 and everything is running fine. My question is to those of you 6.6.2 (the current GA release) and those of you on 6.3.1.
I was going to upgrade to 6.2.2, just to keep my system up to date, but according to the NOW site there are a good few more active systems running 6.3.1.
Would 6.3.1 be a better upgrade to go to? I also see that there is now a
6.4
first customer shipment release (12th Feb) but I think I'll leave that for those of you who have filers to play with.... :o)
So 6.6.2 or 6.3.1?

Greetings.
If anyone is using the feature of ONTAP called "widelinks," can you speak up, or email me privately? Widelinks are a way to allow CIFS clients to follow UNIX symbolic links between *differnet* filers. It sounds cool, and the config looks straightforward, but I can't seem to get it to work.
