CommVault Archiver module (HSM) and OnTap 7.3?
by John Stoffel 02 Oct '09

02 Oct '09

Hi all, Does anyone know what the bug number that is fixed in OnTap 7.3.x so that CommVault 7.x will work properly with stubs to restore files which have been moved off to secondary storage? We're currently running 7.2.6.1 and 7.2.6.1P8 on our filers, and I just want to see if I can figure out which fpolicy (my assumption) bug was fixed. As I understand it, the bug was that on the first access, the file wasn't restored, but on the second it was. This could lead to problems if users found the stubs and either edited them or worse, thought their data was hosed. Of course, moving to 7.3.1.1 won't be too hard, but with all the new iSCSI Luns we've been adding, it makes upgrades harder than when we were just NFS/CIFS exports. Reboots are much simpler then. *grin* THanks, John John Stoffel - Senior Staff Systems Administrator - System LSI Group Toshiba America Electronic Components, Inc. - http://www.toshiba.com/taec john.stoffel(a)taec.toshiba.com - 508-486-1087

Re: missing ops? messages file and `qtree stats` data inconsistency

I compared the output of the three following stats, 60 seconds apart, and clearly the qtree stats is the smallest of the three: qtree stats 972297 cifs stat 2396439 uptime 2395260 However, given our workload, we have tons of CIFS getattrs, and a small fraction of reads or writes. So, I think our suspicions are true (not all ops are reported by qtree stats) but the specific excluded ops in our case seem to still be off. Hrmph. Until next time...

Re: Other OPS?
by Mike 02 Oct '09

02 Oct '09

Metadata work, mostly - directory crawls, access checks, things like that (in CIFS). In NFS, ACCESS, READDIR, READDIR+ , stuff like that. I think you can use 'cifs top -s ops' to see the busiest clients hitting the system. If the ones at the top have very high ops, but not many reads/writes, those could be your guys. That said, it's all about latency. If it isn't driving latency higher, shouldn't be a concern. Those are different stats commands, though, can't remember right now...... --- On Fri, 6/5/09, Page, Jeremy <jeremy.page(a)gilbarco.com> wrote: > From: Page, Jeremy <jeremy.page(a)gilbarco.com> > Subject: Other OPS? > To: toasters(a)mathworks.com > Date: Friday, June 5, 2009, 3:10 PM > > > > > > > > > > > > > > > > What > causes other ops? > I understand that pretty much everything that hits the > filer requires something > but I am seeing what looks like a very high number of other > ops when I do a > stats show.

Snapmanager - eMail issue
by Buerger, Andreas 02 Oct '09

02 Oct '09

Hey Toasters, We're experiencing problems in our Snapmanager environment: Since our eMail team changed the mailrelay hosts, we are not able to send emails with Snapmanager applications anymore. We tracked the problem down to the root cause and found that Snapmanger doesn't use the FQDN in the SMTP Helo cmd to connect to the email relay. According to RFC 821 (SMTP Protocol) the FQDN has to be submitted otherwise the mail relay "normally" does not accept the message (some mail relays do, some don't and ours doesn't accept it). Did anybody run into the same issue before? Is there any known solution or workaround for this problem, without installing any additional apps on windows ?

Thanks for info, for now. I've discovered a tool I didn't know. LogicMonitor seems really a good tool. Together with Operation Manager I remember that also DFM could do the job. Right?

RE: I am walking for ... many (last email)
by grant_travis＠emc.com 14 Sep '09

14 Sep '09

Hello and Thank you! The team that I walk for, Rich's Road Crew, finished in high spirits yesterday. Last year there were 20 walkers on the team and we raised just over $20,000. This year there were 62 walkers and so far we have raised over $45,000. Every donation counts against the fight and I will be thanking every individual that donated personally. Your honorees were all on my shirt as is the Jimmy Fund Walk tradition. Your money is going straight towards the Dana Farber Cancer Institute and their efforts to Conquer Cancer. The fundraising is active until November, so it is not too late yet http://www.jimmyfundwalk.org/ttgrant <http://www.jimmyfundwalk.org/ttgrant> ). :) I want to honor my largest supporter who is an ex Corona Del Mar High School Water Polo teammate and now a successful District Manager and colleague at EMC who put up $500. The majority of the funds raised for Rich's team has come through hundreds of smaller donations each and every penny of which is sincerely appreciated. Thank you to all. 6,000 walkers joined the event this year to help contribute to the expected 2009 tally of $6.5M. While I chose to walk the entire route (26.2 miles along the entire Hopkington to Boston Marathon Route there are 5 routes to choose from --- the choices are derived in part because many current patients participate. One of the starting points is from the Dana Farber Cancer institute itself where many patients, family members, and friends start a two mile route to join everyone else at the finish. http://www.necn.com/Boston/Health/2009/09/13/Thousands-walk-for-Jimmy-Fu nd/1252882245.html <http://www.necn.com/Boston/Health/2009/09/13/Thousands-walk-for-Jimmy-F und/1252882245.html> Walking sounds so simple... but my raw feet tell me that the Boston Marathon route is at least a solid test and seeing all of the patients highlighted along the route and walking with us yesterday, I certainly have nothing to complain about today. Thank you and warmest regards, Travis Grant Registered Donor of the National Marrow Donor Program (marrow.org) http://www.jimmyfundwalk.org/ttgrant <http://www.jimmyfundwalk.org/ttgrant> PS this is the last email I will be sending as a broadcast, thank you for your patience. ________________________________ From: grant, travis Sent: Tuesday, September 08, 2009 1:22 PM Subject: Hello, In the Winter of 2007 my good friend Rich Haskins was diagnosed with a terminal form of Leukemia. Since then Rich has been stoically positive, and is an incredible influence and motivation to me as a business leader, father, husband, and Friend. Last year we rallied around Rich to help raise funds for the Dana Farber Cancer Institute through the Jimmy Fund Walk. This gave me a chance to walk for those in my family that have so far successfully fought off breast cancer - my Mother-in-law and both my maternal and my paternal grandmother. For a close family friend that lost the fight. The attached photo is of my sleeve from last years race with all the names of those just mentioned. For those that you know, for those that have inspired you, please join me in supporting the fight against cancer. Make a donation this week through the following portal: http://www.jimmyfundwalk.org/ttgrant I will be walking 26 miles along the Boston Marathon route. I am proposing that you pick either 50 cents a mile ($13), 1 dollar a mile ($26), or 4 dollars a mile ($104). Warmest Regards, Travis Grant

SMVI / VMWare Experiences...
by Ken Williams 14 Sep '09

14 Sep '09

I'm looking for some experiences people out there may have with SMVI with NetApp. We're currently experiencing major issues with SMVI snapshots failing. I've had open tickets with NetApp/VMWare/Microsoft for 3 months and still have yet to have a solution. My environment looks like such: * 6 x HP DL380 G5 (32gb Ram) in a ESX Cluster * Dual Emulex 10000 Cards in each host. * Cisco MDS SAN * Netapp FAS3070 Cluster ~9tb aggregate for VMWare. * VMFS Datastores ~10-15 VMs per datastore. ~50gb per VM. * ASIS Turned on * Volume and LUNspace reservation turned off * OnTap 7.2.5.1 * Windows 2003 Guest OS. I cant see us reaching any limitation on the Filers or the SAN. Yet we have random VMs failing snapshots every night. Are other people seeing these issues? (I've gone through the gamut of troubleshooting, version management of ESX/VMWareTools/etc). Snapshots timeout and fail at the VMWare/Guest level, not at the Netapp snapshot level. We want to have SMVI function with VSS enabled. Has anyone had failing snapshots been able to resolve a similar issue? Or does anyone have SMVI working properly that we could use as a reference to compare configuration? __________________________________________________________ Ken Williams Storage Administrator, Business Technology Operations Sacramento Municipal Utility District E-Mail: kwillia(a)smud.org Phone: (916) 732-6744 Cell: (916) 240-4213

Problems connecting to CIFS share from some Windows XP clients
by Roy McMorran 10 Sep '09

10 Sep '09

Hello all, I'm trying to troubleshoot an odd problem with a handful of Windows XP clients. When trying to map a drive to a CIFS share on the NetApp, the operation will fail with the obtuse message "a device attached to the system is not functioning" (or system error 59 in the case of a command-line "net use"). What is odd is that a pktt trace on the filer shows the Windows client is trying to connect via HTTP rather than CIFS (we're not licensed for HTTP, and that's certainly not what we want anyway): Client: OPTIONS / HTTP/1.1\r\n Request Method: OPTIONS translate: f\r\n User-Agent: Microsoft-WebDAV-MiniRedir/5.1.2600\r\n Host: xxx.xxx.xxx\r\n Content-Length: 0\r\n Connection: Keep-Alive\r\n \r\n Filer Response: HTTP/1.1 503 HTTP is not licensed.<p>To administer this filer, use <a href=/na_admin/>/na_admin/</a> .\r\n Response Code: 503 Server: NetApp/7.2.5\r\n Date: Thu, 10 Sep 2009 15:35:49 GMT\r\n Content-Length: 188\r\n Content-Type: text/html\r\n \r\n It never tries CIFS (SMB). The problem machine (of the moment) is trying to connect via a wireless router; moving it to a wired connection (on the same IP subnet as the filer) stops the problem occurring. However, I have seen the problem occur with wired connections as well. And also, many other clients machines work just fine via the same wireless connection. I doubt that this is a NetApp problem per se, but I'm hoping someone else may have seen this before. Any thoughts? Thanks! -- Roy McMorran Systems Administrator MDI Biological Laboratory mcmorran(a)mdibl.org

restrict access to volumes to particular protocols
by Peter D. Gray 09 Sep '09

09 Sep '09

Hi people Is there any way to restrict access to volumes to particular protocols eg /vol/oracle can only be accessed by NFS /vol/myshares can only be accessed by CIFS I have become a bit concerned because it looks like domain administrators can set up shares willy nilly and I really want better security than that on some of my volumes. Is there some way to do what I want? Regards, pdg -- See mail headers for contact information.

SQL 2005 reacts badly to a cluster giveback ?
by Raj Patel 06 Sep '09

06 Sep '09

Hi. We've had a couple of cluster-failover events on our FAS270c (watchdog errors every time) on 7.2.5.1 The failover is fine (AFAIK) when one of the nodes reboots - however in the Giveback it appears that the SQL server has a couple of initiator errors events logged and although the drives are visible (and working in terms of I/O) and the SQL services are still running any SQL dependent applications just don't work after the giveback. As soon as I stop/start the SQL services its all back to normal (or I reboot the box). Server is Windows 2003sp2, its a VM on ESX3.5, the iSCSI interface goes through a dedicated iSCSI NIC (a virtual switch which also carries the ESX iSCSI LUN's) Snapdrive is 6.01, iSCSI initiator is 2.03 and its a 32bit VM. Oddly Exchange didn't miss a beat (they're physical Windows 2008 64 bit servers) but SQL was definitely unhappy (even though the SQL service itself carried on - ie it didn't stop). Any ideas ? I note theres a newer iSCSI initiator available (2.08) from Microsoft. I'm pretty sure we haven't had this Giveback issue with our old SnapDrive 4.2.1 setup on the same server. Thanks in advance, Raj.

Re: unix UID change on NTFS file systems
by Tim Thomas 28 Aug '09

28 Aug '09

Sorry, perhaps I was not clear. We are not using mixed security style on our qtrees. and our userids do map properly between the UNIX and Windows worlds. We use a combination of NTFS and UNIX security style across our 50+ filers. So if you have a user that has files in both NTFS and UNIX qtrees with say UID 1000, and then you change them to UID 1025, you simply chown the files in the UNIX qtree from 1000 to 1025, however if you do an LS on the NTFS file system it still shows 1000 and that is because the filer embeds the UNIX UID in the NTFS file. Why? You tell me... Sure they still have access, but the LS sure is deceiving.

Its much appreciated. I'm at my wits end. I've been working with VMWare/Netapp/Microsoft for quite some time on this issue. ESX 3.5 Up4 Not always the same VMs, low load vms at that.

The comment was more of a troubleshooting step. My bad. I have had problems with "busy" servers. I had to stop the "busy making" service. For example. I am running dfm 3.8 and I have to stop the db service before the snapshot. Seemed to band aid the problem. What version of esx and release r u on? Is it always the same vm's that fail?
