Async snapmirror relationship between FAS3050 and R200. Snapmirrors starting failing one day - They have been set up for a year or more and ran without issue. Now, sometimes they complete, sometimes they appear to "hang". Ontap 7.0.4P9 on both source and dest. What could this error indicate? "Error in snapmirror sync mode negotiation" Thanks

replacing a broken disk in 5.3.6R2
by Frank Smith 19 Oct '06

19 Oct '06

It's been a long time since I've dealt with NetApps, so there may be a simple solution to this that I've forgotten. Had a couple of disks fail on an old F720, the first one caused a rebuild onto the hot spare, the second one put it into degraded mode. An admin pulled the dead drives (w/o first doing a 'disk remove') and inserted a two of the same size drives from a retired system that used to be its twin (same H/W and firmware), but sysconfig -r still shows the 2 disks as broken. The references I have all seem to be for later releases, as priv set advanced disk unfail <DISK> comes back with disk: Did not recognize option "unfail". Also, I seemed to recall that the replaced drives would show up as foreign volumes since they weren't zeroed on the old system, so perhaps the system just doesn't realize the drives were replaced. I also remember that years ago when I hot-swapped a drive, the 720 seemed to 'freeze' for a minute or so, but the guy who replaced the drive said he didn't notice any pause in the activity lights on the other drives as he was replacing the failed drives. I did remember that it will only run for 24 hours in degraded mode, so I've set raid.timeout to a bigger number to buy me some time. Any suggestions on how to get it to recognize the 'new' disks?

RE: NSO-151 - NetApp SAN Exam-Dumps
by Sphar, Mike 17 Oct '06

I've only taken the first basic exam, a while back at the urging of my manager, and amusingly one of the things I got dinged on was that I apparently did not know how to request replacement parts on the website, despite the fact that I've been actually *doing* that periodically for about 10 years now and have never had a problem. Personally, my opinion is that while reading/studying the manuals will probably get you close, you will have a tough time passing the tests without actual administration experience. And conversely even years of administration experience may not be enough to pass without some backup studying as well, unless your lucky enough to work someplace that utilizes almost all available Netapp products/functionality. -- Michael W.

We do almost the same. We pull every week the data from dfm in a sql 2005 database and use the report module of ms sql 2005 to make reports. We need an overview longer than 1 year and we need also to track data movements. This last thing (I move a qtree/volume to another filer) is very difficult to do in dfm. This is a new resource for dfm. We have create in dfm a lot of custom tags that we use to build our reports.

RE: Interesting FAS250 note on Tape connectivity
by Learmonth, Peter 11 Oct '06

11 Oct '06

Hi Guys Couple notes on ROHS v. non-ROHS FAS250/270. Yes, all the FC connections are now SFP sockets. ROHS FAS270 has two SFP ports: one for tape or FC SAN (with SFP installed) and one for disk expansion shelves (no SFP installed). ROHS FAS250 has one SFP port for tape (with SFP installed). You can tell in sysconfig -a or -v which one you have by the manufacturing part number (a.k.a. 3x5 number) FAS250 non-ROHS 110-00016 FAS250 ROHS 110-00052 FAS270 non-ROHS 110-00046 FAS270 ROHS 110-00051 Supposedly, all units shipped after a certain date (08 May 2006) are supposed to be ROHS versions. I haven't found that to be entirely reliable. As for what you get via RMA, "It depends (tm)". Basically, if you have ROHS, you should get ROHS. If it ships to a ROHS country and it's after the ROHS compliance date, you get ROHS even if you originally had non-ROHS. If it ships to a non-ROHS country and you have non-ROHS, you get a non-ROHS replacement, at least until they run out. In general, the only problems with getting a ROHS replacement for a non-ROHS is tape connection on FA250 and shelf connection on FAS270. For the non-ROHS FAS250 and tape, if you have an optical tape interface, you're probably using some kind of converter, like Tim Naple was talking about. Now you don't need it. If you have a copper connection to tape, you need a different cable with SFP instead of HSSDDC2. For FAS270 shelves, you'll need X6530 SFP-SFP shelf cables from each head (i.e. 2 in a cluster) to the first shelf. I don't know if the RMA procedure checks for that, but you can certainly tell from sysconfig (it lists both the head part numbers and the modules in the shelves). Personally, I think the change to SFP is a good thing since overall it greatly simplifies cabling. Share and enjoy!

FAS960: backup speed vs simultaneous dumps...?
by Glascock, Donald 11 Oct '06

11 Oct '06

Hi, Toaster folks -- We're a small research group on our third Filer, which is a single FAS960 with five shelves on two cross-connected 2-Gb loops. We trigger flexVolume-level dumps of our one aggregate directly to 2-Gb-fibre-connected LTO-3 drives. When we dump two volumes simultaneously to two tape drives, the time taken to dump each volume increases by a third to a half again, compared to dumping each volume independently. For example, a stand-alone dump may take two hours, but if another dump of another volume to another drive is run simultaneously, then that two-hour dump becomes a three-hour dump. Adding a third simultaneous dump to a third drive causes an even greater increase in dump times. For diagnostic purposes, I've launched a conventional dump of one volume triggered via NDMP our backup software, waited for the dump to reach Phase-IV (the writing-data phase), and launched from the FAS960's console a dump of another volume to the FAS960's null device. Soon after this second dump starts, the write speed on the tape drive associated with the first dump falls off by quite a bit. This write speed picks up instantly when I kill the second dump. Since the second dump was only in Phase-I (inspecting files, but not writing them), and since this second dump was to the local null device anyway, I'm led to think that the performance issues lie somewhere within the Filer's head and Disk I/O subsystem. With one-at-a-time backups of our volumes, our full backup window is about eight hours (for about two terabytes). We were planning to buy two more shelves in early 2007. Should I expect a FAS960 to handle two or three simultaneous full dumps without a significant loss in dump speed? Are you getting nearly-linear performance out of your simultaneous dumps? Thanks for your time & have a great day! Don Glascock -- Donald S.
