LTO4 usage?
by Darren Dunham 06 Jun '07

06 Jun '07

I did some searching and I couldn't find any information about LTO4 support in OnTAP. I'm just doing some investigation on some possible drive purchases. Before I call netapp, has anyone else checked to find when LTO4 support might be expected? Anyone using LTO4 with OnTAP today? Thanks. -- Darren Dunham ddunham(a)taos.com Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?

RE: cifs terminate username?

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. NetApp customers can request access to SDK through their NetApp sales representative.

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?

Dual-domain CIFS
by Nils Vogels 30 May '07

30 May '07

Hi, In a cluster, since there are two heads, it is possible to make each head member of a different domain for CIFS. Will this cause problems during failover?

R200 AT-FC2/FCX
by Carl Howell 30 May '07

30 May '07

We currently have an R200 with six AT-FC2 shelves. We want to add three AT-FCX shelves. Currently, we only have two loops and the AT-FC2's are spread across both of them. Should I move all of the AT-FC2's onto one loop and put the AT-FCX shelves on the other loop or just add the AT-FCX's to the current loops? Thanks, --Carl

Re: ndmpcopy for Linux

Hi, I was able to build it on RHEL4, running kernel 2.6.9-42.EL. Grab the bits from here: http://www.ndmp.org/download/ndmpcopy The mods I made to get it to build were only in 2 files: ./src/Makefile 37c37 < LIBS = -L$(LIBDIR) -lndmp -lsocket -lnsl --- > #LIBS = -L$(LIBDIR) -lndmp -lsocket -lnsl 39c39 < #LIBS = -L$(LIBDIR) -lndmp --- > LIBS = -L$(LIBDIR) -lndmp ./lib/ndmp_common.h 40c40 < #define XDR_AND_SIZE(func) (bool_t(*)(XDR*, ...))xdr_##func##,sizeof(func) --- > #define XDR_AND_SIZE(func) (bool_t(*)(XDR*, ...))xdr_##func ,sizeof(func) I did not run any exhaustive tests after I built it, but hopefully this will at least get you started.

Max number of LUNs

Hello, In relation to the recent threads on max inodes and max dir size I was wondering if anyone has any experience with the limit on the number of LUNs in a filer? Kind regards,

I presume this is one of the features coming out in the new 10.1 release?
