Balanced clusters?
by Peta Spies 21 Apr '08

21 Apr '08

Hi, We normally build our clusters as per (what I believe is) best practice, with equal number of identical shelves on each loop. However, we've hit an emergency situation where a currently unused (and not in the aggr) shelf on one head would really really really be much more useful on the other, to grow a very full volume on there. Due to the nature of the problem, just presenting a new volume from this shelf is not a good enough fix; I need to grow the existing volume. Asap. So how bad of an idea would it be to wire that shelf into the other head? Will the cluster complain? The cluster in question is a 3040C, and we'll end up with 3 sata shelves on one head and 1 on the other. Peta

Licensing Question
by Peter Rosenthal 21 Apr '08

21 Apr '08

Hello, We are considering getting some used netapps equipment. I am mostly concerned with the pitfalls of licensing and would be grateful for any pointers. Specifically we are currently looking at a FAS270. We want to connect it via fibre channel to a FC switch and then two FC HBAs on different hosts. I do not want to end up with a door stop product and therefore I would like to know if: Will I have any problems resetting any existing passwords that might exist on the filer? Is the license required to access the filer via fibre channel optional or will any licensed filer support it? Thanks.

The issue seems to be with removing the shelf from the current filer. We support hot 'adds,, but not hot 'removes.'. But there are other things to consider as well, such as the volume or aggregate association of the disks in the shelf you will remove and the resulting state of vol0 or the containing aggregate thereof. So if any disk belonging to vol0 or that aggregate are in that shelf, you need to do some swapping around during that outage where you will have to shutdown the existing head to remove the shelf and 'hot add' it to the other head. I would call the support center regardless to ensure no steps or caveats are missed as their resources and skills scale best for these procedures. Good luck ....

Re: RJ45 Serial

For a second, I was thinking that you used a filer to login to a cisco serial console ;-) Pardon brevity, typos, etc; sent from mobile. -----Original Message----- From: Steve Rikli [mailto:sr@genyosha.net] Sent: Sunday, April 20, 2008 09:05 PM Pacific Standard Time To: Peter Rosenthal Cc: toasters(a)mathworks.com Subject: Re: RJ45 Serial On Mon, Apr 21, 2008 at 04:29:28AM +0100, Peter Rosenthal wrote: > Hi Folks, > > RJ45 console serial pinouts look the same as cisco. Has anyone tried using a > cisco serial cable on a filer with an RJ45 serial console? We have done the reverse -- e.g. use the FAS250/270/3050/etc. RJ45:DB9 console cable on Cisco gear with RJ45 serial console, and it worked fine. So I assume it would work in the other direction too. sr.

Re: Upgrade 900 series to 3000 series filer
by Davin Milun 19 Apr '08

Strangely, the doc that NetApp pointed me to, when I opened a support case for upgrading a pair fo 960's and 3040's, does not include the mailbox destroy commands: http://now.netapp.com/NOW/knowledge/docs/hardware/NetApp/cs_migration/FAS90… I've asked if they're needed - hopefully I'll get a meaningful response back (rather than a suggestion that I go pay for some NetApp Professional Services to get upgrade help - which was the other half of the response that pointed me to that doc).

"nfs_hist" and "lun hist" output questions
by Pascal Dukers 17 Apr '08

17 Apr '08

The nfs_hist command shows e.g. the number of reads that get serviced with a specific response time: v3 read: 4817066 (blocking requests) - millisecond units 0 1 2 3 4 5 6 7 4144583 475420 86036 25125 16078 11301 9468 6301 What is the exact range for e.g. "0"? I would expect it to be between 0 and 1 ms and not exactly 0 ms. Can someone confirm this? And another question about the "lun hist" command. What is the difference between scsi_write and scsi_write_extended? -- View this message in context: http://www.nabble.com/%22nfs_hist%22-and-%22lun-hist%22-output-questions-tp… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

Serious A-sis bugs
by Darragh, Stephen J (CSC) (US SSA) 16 Apr '08

16 Apr '08

If you are running a-sis with 7.2.3 or 7.2.3, there are a few bugs that can cause the filer to panic and mark that volume offline forcing a wafl_check on the containing aggregate. Not only that, but we had to netboot a developer release and had extensive outages. We have been told that 7.2.4 had fixed these bugs, but if you have run asis on an old version, the bug may be there dormant. I believe these were the bugs that were identified in our incident report. bug 256799 Bug 266312 Bug 276084 bug 266312 bug 251673 The bug hit our primary storage, and it also his the VSM volumes on our DR filer, and it would is in the ACL/directory of the backup tapes as well.
