RE: volume/shelf containment
by abond＠netapp.com 10 Jul '00

I'd like to put the cat among the pigeons here(!), and ask why you feel it is necessary or desirable to "contain each volume to a shelf of its own". The same situation you have seen here is likely to occur again if another disk fails (it will, eventually). One reason to buy a filer is to minimise administration and maximise uptime, and this process will increase administration as well as introduce unnecessary downtime. One possible explanation is that you need to move some disks later to another filer - in which case identify at that time which disks comprise the volume you wish to move, and then simply move those. As mentioned by others, if you halt the filer, you can move the disks around with no fear whatsoever of confusing the filer - the disk's identity is not related to the slot in which it finds itself, rather to the label on the disk. It is also desirable to minimise the number of "disk fail" operations, following the maxim of "if it ain't broke, don't fix it" :-) Regards, Andrew > -----Original Message----- > From: Fox, Adam > Sent: 10 July 2000 15:55 > To: toasters(a)mathworks.com > Subject: RE: volume/shelf containment > > > There is a simplier way to do this, but it involves halting > the filer. > > You could simply, halt the filer, place the disks where > you want them, then reboot. > > Sorry I didn't mention this obvious way before, but I > tend to think in terms of no downtime. > > -- Adam Fox > NetApp Professional Services, NC > adamfox(a)netapp.com > > > > > -----Original Message----- > > From: Fox, Adam > > Sent: Monday, July 10, 2000 10:38 AM > > To: makin(a)dnrc.bell-labs.com; toasters(a)mathworks.com > > Subject: RE: volume/shelf containment > > > > > > > > > > > -----Original Message----- > > > From: Bhavnesh Makin [mailto:makin@dnrc.bell-labs.com] > > > Sent: Monday, July 10, 2000 10:04 AM > > > To: toasters(a)mathworks.com > > > Subject: volume/shelf containment > > > > > > > > > We have a F740 filer with two 18 gig shelves.

I 'm new at this NetApp stuff so you may want to get a second opinion but if you pull the rebuilt spare then the first volume will rebuild it on the other spare. Plug it back in and it is now a dirty spare. Chuck This is true, but if you KNOW the disk is good, you can run the disk_zero command (I think you have to rc_toggle_basic first). Then pop the disk out and put it back in, and *poof*, it's a regular spare again! Little tricks that may help you! -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com

There is a simplier way to do this, but it involves halting the filer. You could simply, halt the filer, place the disks where you want them, then reboot. Sorry I didn't mention this obvious way before, but I tend to think in terms of no downtime. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Fox, Adam > Sent: Monday, July 10, 2000 10:38 AM > To: makin(a)dnrc.bell-labs.com; toasters(a)mathworks.com > Subject: RE: volume/shelf containment > > > > > > -----Original Message----- > > From: Bhavnesh Makin [mailto:makin@dnrc.bell-labs.com] > > Sent: Monday, July 10, 2000 10:04 AM > > To: toasters(a)mathworks.com > > Subject: volume/shelf containment > > > > > > We have a F740 filer with two 18 gig shelves.

As far as I understand it, spares are global to the filer. The filer will pick the smallest spare disk that will fit. So unless you have different sized disks on different volumes, you can't make a filer pick one disk over another. As far as fixing your current situation. Config your system now so that it only have 1 spare (it may be that way anyway now), then fail over the spare in the 2nd shelf which is now a data drive for the volume on the first shelf. In my opinion, the best way to do this is to run the 'disk fail' command rather than pull the drive. I think it's cleaner since you won't have to cause your lop to reset. Then you will force your volume to rebuild on the only spare in the system, which not so coincidentally is the one you want. Hope this helps. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com

Ferdie, Grasping at straws... After your toaster comes up, if you enter 'ndmpd status' from the console or admin host, is the status 'ON' then? If so, perhaps it's just timing. Maybe the process to switch on ndmpd hasn't completed yet when the 'ndmpd status' command is read. Try moving the 'ndmpd on' up a few lines in the /etc/rc file - like just before the 'options' calls - to give it a bit more time.

Both of my filers still have the "nfs on" entries and they're working fine, and the entries after that are being executed. -- Mike Sphar - Sr Systems Administrator - Engineering Support Services, BOFH, GWP, MCP, MCP+I, MCSE, BFD -----Original Message----- From: Bruce Sterling Woodcock [mailto:sirbruce@ix.netcom.com] Sent: Friday, July 07, 2000 12:25 PM To: Ferdie Mazon; toasters(a)mathworks.com Subject: Re: NDMPD Is the "nfs on" entry even required anymore?

If you do the ndmpd status from the console what do you see? There is a quirk that some of the commands issued in rc actually are "finished" after the rc file has completely run. "ndmpd on" is one of these. If you do ndmpd status from the rc file, it will not show that it is on yet because the action hasn't been taken yet. If you see that ndmpd status shows that it is on from the console, I guess that this is what you are seeing.

Doublecheck syntax. Check the entire /etc/rc file. Make sure you don't have a 'ndmpd off' statement someplace after the 'ndmpd on'? > ---------- > From: Ferdie Mazon[SMTP:ferdie@san.rr.com] > Sent: Friday, July 07, 2000 9:07 AM > To: toasters(a)mathworks.com > Subject: NDMPD > > I have a problem with my 760 filer.
