RE: Replacement disk problem

I agree 100%, but there is also a safety measure built in. "vol destroy" will only work against offline volumes. If you try to "vol destroy" the online volume, the command will puke and die with a message about the volume needing to be offline first. From what's below, Vol0(1), the foreign volume with disk 8a.13, will be offline. It can't be brought online because it's both incomplete and foreign. Vol0, the real and active root volume, will be online. This can easily be confirmed with a "vol status" command.

Actually, there is a copper FC HBA on the back of the 250 for doing NDMP or regular dumps directly to tape.

RE: OnTap 6.5.2/6.5.2P6/6.5.2R1 ?
by Hill, Aaron 14 Sep '04

14 Sep '04

My two cents; I have nothing good to say about 6.5 yet as it has caused us numerous panics and disconnects since it was released. It seems a new patch/debug for it is released very week. For the F840, there are some problems with CIFS and XP-SP2 that can prevent clients from connecting, so I would definitely upgrade to a version that addresses that issue. Which version? See if you can get a 6.4.x.... version to use until the 6.5.2R1 gets released. At this stage it looks like it is 1-2 weeks away. Once 6.5.2R1 is released, I would move those Nearstores to it immediately, if only to avoid that Rapid Raid Recovery (or disk copy) bug (Bug#139525) that punished one of my systems using 6.5.2 last week. 6.5.2P6 was released to address it and other issues, however you can work around it specifically by temporarily disabling the raid.disk.copy.auto.enable option. Go R1 and then switch it back on. We are at 6.5.2. I am going to skip 6.5.2P6 due to some possible issues that may affect our environment and go directly to 6.5.2R1 when it becomes available. At the end of the day, you need to look at the bugs and compare them with your environment in order to determine if you are at risk. I hope this makes the decision a little easier. --Aaron -----Original Message----- From: Simon Ferrett [mailto:simon@musicmatch.com] Sent: Tuesday, 14 September 2004 4:59 AM To: toasters(a)mathworks.com Subject: OnTap 6.5.2/6.5.2P6/6.5.2R1 ? Hi Folks, Last week I updated my three nearstore units to 6.5.2 after experiencing a shelf-hang issue on two of them. That got me to thinking about updating another system (a F840 running 6.1R1 - it's been up forever, about 420 days) since it's running such an old version of OnTap and some of the clients here in the office are migrating to to XP-SP2. Anyhow - looking on the NOW site I noticed there are a few critical bugs in 6.5.2 which are supposed to be fixed in 6.5.2R1 - which doesn't exist yet. 6.5.2P6 does exist, however, so I was curious if I should wait until P6 becomes R1 before upgrading? I hate to rock the boat on a system which has been up and stable for a year and a half, but with XP-SP2 clients coming online I'm sure there's going to be some issues come up with the old 6.1 version its running. Also I was curious if I should also re-update the 6.5.2 systems I have to R1 when it comes out just to be sure that I'm not going to hit any of the known issues in 6.5.2 on them. Is anyone running 6.5.2P6 here on the list or have any comments about the actual critical-ness of those bugs in 6.5.2 which have been fixed in P6 (or R1 when it becomes available) - or know when 6.5.2R1 might hit the streets? The NOW site says 'this week' but I'm not sure when the document was authored... Just curious what the general consensus was on 6.5.2/6.5.2R1 etc. Cheers, Simon. --- This email message and any attachments are for the sole use of the intended recipient(s) and may contain confidential and privileged information.

RE: using NDMP for backups
by Alan Biren 14 Sep '04

14 Sep '04

Skip, BackupExec has a very limited implementation of NDMP. I believe for NetBackup it is an additional license. Dumps can be done in different levels 0-9 with zero being a full backup and 1-9 being incremental since the next lowest integer. ie: 0 level on Sunday, 1 on Monday, 2 on Tuesday, 3 on Thursday, 4 on Friday, 5 on Saturday. This would give you an incremental for the week with full dumps on Sundays. Differentials can be defined as well. As far as scheduling, that would require some non-NetApp scheduler to perform. Windows Scheduler to kick off an rsh session. I have used many different backup platforms and the easiest to use I have found is BakBone's NetVault. I also like BakBone's Integration with NetApp. They are the developers of SnapVault and have plug-ins available to perform SnapMirror to Tape. I would have to agree with Tim. NDMP is a better utility to use for backing up to a robotic library. You get to take advantage of the media changer and can utilize multiple drives for backups. While with dump you can only use a single drive/tape system. A waste of your scalar 24.

OnTap 6.5.2/6.5.2P6/6.5.2R1 ?
by Simon Ferrett 13 Sep '04

13 Sep '04

Hi Folks, Last week I updated my three nearstore units to 6.5.2 after experiencing a shelf-hang issue on two of them. That got me to thinking about updating another system (a F840 running 6.1R1 - it's been up forever, about 420 days) since it's running such an old version of OnTap and some of the clients here in the office are migrating to to XP-SP2. Anyhow - looking on the NOW site I noticed there are a few critical bugs in 6.5.2 which are supposed to be fixed in 6.5.2R1 - which doesn't exist yet. 6.5.2P6 does exist, however, so I was curious if I should wait until P6 becomes R1 before upgrading? I hate to rock the boat on a system which has been up and stable for a year and a half, but with XP-SP2 clients coming online I'm sure there's going to be some issues come up with the old 6.1 version its running. Also I was curious if I should also re-update the 6.5.2 systems I have to R1 when it comes out just to be sure that I'm not going to hit any of the known issues in 6.5.2 on them. Is anyone running 6.5.2P6 here on the list or have any comments about the actual critical-ness of those bugs in 6.5.2 which have been fixed in P6 (or R1 when it becomes available) - or know when 6.5.2R1 might hit the streets? The NOW site says 'this week' but I'm not sure when the document was authored... Just curious what the general consensus was on 6.5.2/6.5.2R1 etc. Cheers, Simon. --- This email message and any attachments are for the sole use of the intended recipient(s) and may contain confidential and privileged information.

RE: Confusing trusted domain authentication problem

Unfortunately I have limited visibility to the corporate domains, but I believe they are Win2K domains running in native mode. It's possible though that the NEWCORP domain might be Windows 2003 now. I don't see any errors on the F230. I've even got the auth subsystem logging configured for full debug logging but I'm not seeing anything logged when I make a failed authentication attempt. I do have concerns about WINS though. There seems to be some confusion about what, if any, WINS servers are being supported by the corporate folks at this point.

Confusing trusted domain authentication problem
by Mike Sphar 10 Sep '04

10 Sep '04

Don't know if anyone has any suggestions for this fairly annoying problem, but I'm happy to hear any. We've got a development domain here called (for example) ENG, that has for years trusted the corporate domain CORP. My three netapps are members of the ENG domain and any user in CORP can authenticate on those servers via a one-way trust. (ENG trusts CORP, CORP does not trust ENG). We've got a new corporate domain NEWCORP being migrated to, and ENG also has a one-way trust to NEWCORP. Now, everything seems to work fine, *except* for my one very old Netapp F230 running 5.3.7R3D18. (I know, way old and end-of-lifed, we're trying to replace it.) My NEWCORP account can authenticate against my newer netapps, but when I try to connect to the F230, or to a snapserver or a unix server running samba, the authentication fails. So basically it looks like authentication is working for the Netapps running a current OS release and for regular windows servers, but not for 3rd party servers. If we make the samba server authenticate against CORP instead of ENG, then the NEWCORP accounts seem to work. It seems like there must be something different about the ENG -> NEWCORP and ENG -> CORP trusts, or some obscure authentication permissions thing, but we can't figure out what the problem is. (And our primary windows admin is on vacation.) Anyone out there more knowledgeable about trusts and domains (I'm mainly a unix guy) have any suggestions? -- Mike Sphar - Sr Systems Administrator - Remedy, a BMC Software Company

Thanks for all the feedback. I didn't expect so many people to be interested. It needs some cleanup, several extra checks (like making sure your actually talking to a filer, right now it just assumes you know what your doing), and goodies, but it works well enough. You can find the page for it here: http://www.cuddletech.com/code/toasterview/index.html I'll probly makes some improvements and push out a new version next week. In the mean time I'm extending it to do application specific stuff that isn't portable (integration of MRTG graphs, RRD, etc). Thanks for the suggestions that were recieved. I avoid quota's like the plegue but I'm sure I could put in something useful. And I'll add performance data at least in a basic form for the next version. Thanks for all the feedback. This is GPL code, so please feel free to hack it up or bend it to your own purposes as long as you respect the terms of the GPL. benr.

RE: New Simplified Monitoring Tool

Hey Folks, I'm new to the list - "hello" - and have been a netapp user since about 1999. Anyhow just a comment/suggestion on the toasterview stuff, which looks quite interesting, btw: One thing which could be good to show is the % complete for the reconstruction progress. Currently I'm looking after an 840c, 940c, 840, 880, R100, R150-24 and a R200. I had a shelf hang on the R100 and R150 this week resulting in about 10 failed drives, so the reconstruction is taking forever - hence my interest in keeping an eye on the reconstruction progress. It seems like the systems can only do two reconstructs at a time, so I've had raid groups waiting for a drive reconstruction for about 24 hours so far... If you know of a way to increase the number of parrallel reconstructions I'd be interested to hear it. Cheers, and it's good to have finally found a group of other netapp users.

Ben, I like it, how about calling it ToasterIZE :-) Anyway, can I take it for a test drive? Paul Barrette Senior SysAdmin BC Pension Corp -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Ben Rockwood Sent: Thursday, September 09, 2004 4:57 PM To: toasters(a)mathworks.com Subject: New Simplified Monitoring Tool Hello Toasters. Some may have noticed my search for a simplified monitoring tool awhile back. Alas, I never found such a tool. So I finally broke down and just wrote my own. So far I've only got about 2 hours worth of developement into it, but it's mostly what I want already. I thought I'd see if anyone else was interested in it or could propose suggestions for it. It's called "Toasterview" (I wanted to call it ToasterVision, but that seemed to silly) and you can see an example output page here: http://www.cuddletech.com/code/toasterview/europa.html Some notes about this sample page. Firstly, the Head image you see at top does, you'll notice, match the model of the filer so you can "see" what the head looks like reguarless of which model it is; right now F7x0, F8x0, F940 and F9x60 are handled. The logo image in the top right is, of course, intended to be changed to your company logo so that your boss is impressed. The global status box changes from green to red based on status. But, the most interesting and important part for me is the DF output. Using the DF SNMP table I can parse it up and display how I like, so I display volumes in nice round numbers (using 1024 insteal of 1000) for easy reading and a little bar graph that lets you see volume usage in an instant. Also, the last line of the DF table is a "Total" line. This simply adds up the data from all the non-snapshot volumes and displays this information like anything else. It's kinda nifty to be able to take 1 look and confidently say "We're using X% of! the filers capacity" rather than just approximating off the top of your head. Anyway, this is the kind of tool I want. I need to clean up the source so it's pretty and then I'll GPL it. Anyone interested or what to make suggestions? I should note that I'm actually supplimenting this page you see with extra data at the bottom as supplied by RRD graphs and such... however that stuff is all system specific whereas my current script as demostrated works on any NetApp Filer (I guess NetCache too). The colors and stuff need tweeking, but you get the general idea. benr.
