multiple shelf aggregate or single shelf aggregates
by Paul Letta 15 Jun '07

15 Jun '07

We have a new FAS3040 with 3 shelves of 500GB SATA's. It has an onboard controller with 4 ports, and we have 2 expansion controllers with 2 ports each. I'm trying to think about the aggregate layouts. I am thinking that since these are SATA drives, I should put all 3 shelves into 1 big aggregate for performance (to get as many spindles as possible) and then just use flex vols. But then I also am thinking that if I use 3 separate aggregates (1 per shelf), I would have better data protection in case I loose a whole shelf (only loose volumes on that one shelf). Since the raid_size is maxed at 16 for SATA anyways, I am going to end up with a raid group per shelf no matter what (defaults to 14). I've done some write tests. I had an aggregate made from 1 shelf and another aggregate made up of 2 shelves. I didn't see much difference. I was write testing via NFS mounts. The client was on a GigE, and the filer was on a VIF made up of all 4 GigE ports. Is the performance gains from having mutli-shelf aggregates worth the loss of the data protection from a whole shelf failure. As for the FC connections, currently I have all 3 shelves daisy chained with 2 loops, one loop is on the on board and the other loop is on one of the expansion cards. Suggestions ? Thanks ! Paul

Unix script tool to read Windows ACL
by JacekN 14 Jun '07

14 Jun '07

IHAC who had to make an upgrade from 7.0.3 due to SnapMirror bug. 7.0.6 would be sufficient but I convinced him to jump to 7.2.2 due to some interesting features (both releases are GD). I have studied upgrade guide, bugs and all other documentation and I have found no potential problem. But I was wrong... Customer's scripts stopped to work because NetApp introduced undocumented "feature": access rights displayed by NFS3 client on NTFS volumes are empty (all files have d---------) although access rights are correctly mapped. NetApp provided some kind of workaround but displayed access rights are always only rough approximation. Is there any Unix tool that can read native NTFS ACLs? (SecureShare can read Unix rwx from Windows hosts however it cannot be scripted...) It will solve the customer's problem for ever (NetApp can always change the way of approximation in future releases...) Best regards, Jacek --- avast! Antivirus: Outbound message clean.

Problem creating snapshots with SnapDrive for Solaris

I'm having errors creating snapshots with SnapDrive for Solaris. I'm running Solaris 10 on a SPARC processor, Veritas Volume Manager and File System 5 and a FAS270 DOT 7.2.2 filer.

netapp admin with Unix without NFS
by Stephen C. Losen 14 Jun '07

14 Jun '07

I'm accustomed to administering netapps on a Unix box that NFS mounts the root volume and has rsh and/or ssh access to root. I've always used the command line since we got our first filer in 1997 before the GUI came out. We are buying two FAS270s to be placed in two separate locations for disaster recovery. Each filer will store FC LUNs that will be used by a Windows server in each location. One location is primary and the other is standby in case we lose the primary. We will replicate data from the primary filer to the secondary with snapmirror (and also snapdrive I suppose). I am in neither of these locations and each location will be behind its own firewall (oh joy). Obviously the filers will need to talk to each other for snapmirror. Since these filers are FC SAN only, we would prefer to not spring for NFS licenses just for my convenience. I would be interested to know if there are any other Unix folks out there who admin filers without NFS access. I think that all filers come with a mini CIFS license (only one CIFS session?) and I guess I could use smbmount on my Linux box to access the root volume. I wish filers also had a mini NFS license for admin. As for installing DOT, isn't there a way to put the software distribution file on a httpd server and point the filer at it? I have always used the install_netapp script and the compressed tar file. I don't know what sort of holes I can get punched in the firewall. I may need to use a VPN client (yuck). Is anyone else out there in a similar situation?

6070's loosing packets, become unusable
by Todd C. Merrill 13 Jun '07

13 Jun '07

Folks, I'm on a fishing expedition here. We've had four incidents over the past ~6 months of our 6070's loosing packets and becoming effectively unusable. Symptoms include *very* slow response on clients, both CIFS and NFS. Messages file on filer shows problems connecting to all external services (domain controllers, NIS servers, etc.): [selected lines clipped] Wed Jun 6 21:02:23 EDT [xxxxx: nis.server.inactive:warning]: preferred NIS Server xxx.xx.xxx.x not responding Wed Jun 6 21:02:23 EDT [xxxxx: nis.server.active:notice]: Bound to preferred NIS server xxx.xx.xxx.x Wed Jun 6 21:15:10 EDT [xxxxx: nfsap_process:warning]: Directory service outage prevents NFS server from determining if client (xxx.xx.xxx.x has root access to path /vol/YYYYYY/YYYYYY (xid 1346843745).

First time, we just rebooted (the whole company twiddling their thumbs, waiting...). Second time, we begged for diagnosis time and called it in, and ended up replacing the motherboard (suspected network port). *Third* time, we no longer suspected hardware, dumped core then rebooted; core analysis didn't find anything. FOURTH time happened last week; dumped core, sent it in, awaiting analysis but not hopeful. This has only happened on our 6070's. Never on our 980's or R200's (running same ONTAP versions). It's happened on two different ONTAP 7.2 releases. It's happened on three different 6070's (two incidents on one of them). We're running full flowcontrol. We're running vif's. System firmware on six of them (and this latest victim) was upgraded in February 2007. We have eight 6070's in one location; two have been affected. We have six 6070's in another location and one has been affected. The only stat that looks "weird" is that ifstat shows an unusually high number of transmit queue overflows / discards (ifstat from autosupport just before last core dump): > ===== IFSTAT-A ===== > > -- interface e0a (102 days, 11 hours, 43 minutes, 36 seconds) -- > > RECEIVE > Frames/second: 24198 | Bytes/second: 4311k | Errors/minute: 0 > Discards/minute: 0 | Total frames: 384g | Total bytes: 107t > Total errors: 1 | Total discards: 1201k | Multi/broadcast: 0 > No buffers: 1201k | Non-primary u/c: 0 | Tag drop: 0 > Vlan tag drop: 0 | Vlan untag drop: 0 | CRC errors: 1 > Alignment errors: 0 | Runt frames: 0 | Long frames: 0 > Fragment: 0 | Jabber: 0 | Xon: 0 > Xoff: 0 | Ring full: 0 | Jumbo: 0 > Jumbo error: 0 > TRANSMIT > Frames/second: 29384 | Bytes/second: 13057k | Errors/minute: 0 > Discards/minute: 0 | Total frames: 470g | Total bytes: 314t > Total errors: 0 | Total discards: 954k | Multi/broadcast: 123k > Queue overflows: 954k | No buffers: 0 | Single collision: 0 > Multi collisions: 0 | Late collisions: 0 | Max collisions: 0 > Deferred: 0 | Xon: 0 | Xoff: 0 > MAC Internal: 0 | Jumbo: 0 > LINK_INFO > Current state: up | Up to downs: 1 | Speed: 1000m > Duplex: full | Flowcontrol: full Switch side shows no extraordinary errors. So, I'm fishing for some ideas here. Waiting for it to happen again to gather network traces is not an optimal strategy (as much as I'd like to have those traces as well). I'm sure NetApp support will do their best in analyzing the core, but as I mentioned above, I'm not hopeful they will find the culprit this second time. So, I'm looking for any anecdotes, other weird behavior, crazy ideas, or even possible ones [1], from this large group, in parallel with NetApp's efforts.

Farewell all!
by Maglinger, Paul 13 Jun '07

13 Jun '07

Well, it is with deep regret that I bid all you toasters a fond farewell. I'd like to say that I appreciate all the help during the time that our 740 served us for about 8 years. The 740 was a fine device and NetApps support was top-notch. After a very lengthy discussion over several months, we went to another storage solution. By the way, if anyone is interested in the 740 maxxed at 1TB raw and includes a spares kit with motherboard and misc other parts that were never used, send me an email. It is located in the Southern Indiana area. First come, first serve. You have to arrange for transport. If I don't hear anything from anyone by the end of the week, it's going to the recycler. Thanks again to all. If people concentrated on the really important things in life, there'd be a shortage of fishing poles. - Doug Larson ________________________________ Paul Maglinger, A+, CA, CCA, CET, MCSE Systems Administrator Shoe Carnival Inc.

FC Lun creation/connection problems from W2K3
by Fred Grieco 12 Jun '07

12 Jun '07

Toasters, I am having a heck of a time creating and connecting luns from a Windows 2003 Server. I have installed the latest and greatest Snapdrive and DSM on the system, and I'm running Single_image cfmode on a FAS3020C with ontap 7.2.2. Also, I am using dual Emulex LP10000 HBAs on my hosts. When I attempt to create new luns in Snapdrive, the system creates the luns (i can see the IGroups and luns in filerview) but then it times out trying to reconnect to those luns. After this I can see the Luns in the HBAnywhere Emulex software but not in Snapdrive or DSM. Not only that, but I see each lun 4 times, which means the pathing/masking/igrouping is correct. I can also see all 8 drive paths as drives listed in device manager, but there is nothing in Disk Management. Has anyone seen this or know what direction I should go in? I have a call with Netapp escalated to engineering, but I thought I would also reach out to some real experts here!

F85 and F330 available for free
by Conner, Neil 08 Jun '07

08 Jun '07

We have two working systems that we need to dispose of: 1. One is an F85 running DOT 6.5.5R1 with a 100GB volume. 2. The other is an F330 running DOT 5.3.7R3 with an 18GB disk shelf. Both units come with complete documentation sets, but both also need a new NVRAM battery. The recipient would need to pay for shipping. Let me know if you're interested or if you know of a charitable organization that could use either of these units. Thanks, Neil

David, The "ONTAPI" referred in the mail below is actually Manage ONTAP SDK product. Manage ONTAP SDK provide set of interfaces for developing third party integrations to manage NetApp storage. The SDK provide interfaces in C, Java and Perl languages. SDK can manage NetApp storage running ONTAP 6.3 and above. Manage ONTAP SDK is currently used by numerous partners and customers to tightly integrate into their own tools and applications with NetApp storage systems. The SDK can be downloaded from SDK portal( http://now.netapp.com/cgi-bin/manageontap ). The access to this portal is restricted.

cifs terminate username?
by David Lee 05 Jun '07

05 Jun '07

(OnTap 7.0.5) From time to time our admin procedures mean that we have to move someone's home directory from one qtree to another. (I'd rather this didn't happen, but it's one of those things we have to live with for the time being...) Inevitably, on some occasions a CIFS session for such a user is active at the time of the move. So if, the morning after the move, they simply pick up from where they left off the previous evening, their new data is still going into their old area. (This probably happens one every week or two on average.) What we're looking for is something like: cifs terminate username that we could employ to kill off the CIFS session(s) for a given username. (Such killing of potentially active (usually dormant) sessions is (while not ideal) nevertheless usually far preferable to picking up the pieces of two diverging home directories in the following days.) But there doesn't seem to be any such "cifs terminate username". There is a "cifs sessions username", whose output is intended for humans, not machines, so is not easily amenable to reliable machine-parsing. So it is not really suitable for then reliably deriving workstation names for OnTap's existing "cifs terminate workstation" command. Any thoughts on how to achieve "cifs terminate username" functionality? By the way, the environment for driving this is a set of UNIX scripts which can do operations of the form: rsh filer cifs ... -- : David Lee I.T.

Clustered heads with SATA disk shelves?
by Tom Samplonius 04 Jun '07

04 Jun '07

One item that I've researching that is a bit unclear, is that, can I can connect a SATA disk shelf (DS14mk2 AT) to a clustered set of FAS960 heads? I think there is no problem. I assume that you must use the AT-FCx modules, as they are dual-looped. I suspect that the the AT-FCx is mandatory for clustering (as opposed to the AT-FC) , but NOW seems a bit vague, at least according to what I was able to find. Also, I've heard rumors that connecting SATA shelves to a cluster is not really reliable. I was a bit taken a back, as NetApp as the SATA shelves have been out for a while. Is this really the case?

If you want to test your procedure before you actually do it!! I would create a dummy lun and mount the same way dump some data in it, make sure you format the same type of file system.... Remove and try sd.... That wil raise your comfort level... My personal best practice is to try it, back it up, test restore and then do your live work....

I'd say disconnecting the LUN, removing all traces in the iSCSI initiator, then installing SnapDrive, and then using SnapDrive to 'connect' to the LUN is the right way. If I were you, I'd test this using an ONTAP simulator, though ;) Grtz, Nils -- Simple guidelines to happiness: Work like you don't need the money, Love like your heart has never been broken and Dance like no one can see you.

SnapDrive install with existing iSCSI LUNS
by Sean McWherter 24 May '07

I need guidance in setting up SnapDrive on our Windows 2003 Enterprise x64 servers. We have two of these servers clustered hosting our SQL 2000 servers. My question is this: What is the proper way to install snapdrive on a machine that already has LUNs mapped with the iSCSI initiator? Should I disconnect the LUN first? I did read one post on the NOW forums where a guy got hosed by disconnecting the LUN and then installing SnapDrive after someone told him that's what to do. He was never able to mount them back. I'm trying to dot all my I's and cross all my T's before I dive in here.

rysnc and filers

Okay, I am trying to copy data from a DOT-7 to a DOT-GX. I start off with: mount filer7:/vol/src /src mount filerg:/ /gx I then do (from RHEL4U2): cp -a /src/dir1 /gx I then do: rsyn -avH --delete /src/dir1/ /gx/dir1/ There is nothing changing on the source, yet it transfers files anyway. Anyone have a clue as to why? The destination get some files marked with current time, yet others are marked with an older time. -- --tmac RedHat Certified Engineer #804006984323821 Principal Consultant, RABA Technologies 240-373-3926 (office) 301-688-4705 (Lab) 214-279-3926 (eFAX)
