RE: FAS960 / DOT 7.0.1R1 / SAN LUN for Dell servers...?
by Glascock, Donald S. 20 Jul '05

20 Jul '05

Hi -- I've been doing more digging regarding the replies I've received so far: Rich Fenton wrote: > Have you tried running SANSurfer and seeing what targets/luns it > sees - this is usually pretty good at helping to debug problems I downloaded & installed the SANsurferHBA GUI for Linux/IA32 & ran it from one of the candidate boxes. It reports ... Error: SDOpenDevice(0, xx) failed (0x20000074) (Out of memory) Error: **NO** compatible HBAs found during scan - Terminating... ... which isn't overly surprising to me. I didn't expect to have the RedHat Enterprise Linux 3 AS Release 3 recognize & support the Qlogic card without a bunch of steps. One issue is installing the Linux driver for the card. The instructions I've found so far are, well, gnarly at best. Is there something I'm missing about this? But really, if zoning on the switch and masking on the NetApp are correct, shouldn't one be able to see the LUNs from the Qlogic Fast!Util BIOS configuration app? Or am I mistaken about this? Britt Bolen wrote: > You definitly use the WWPN not the WWNN in the igroups. > > You must use an igroup to map a lun, there's no way around it. > > When you're probing the luns from BIOS does 'fcp show initiator' > list the initiators as logged in? I'm 99% certain that I'm using the cards' WWPNs, as listed by the switch. When booting one of the candidate Dell servers & firing up Fast!Util, "fcp show initiator" lists: servername> fcp show initiator Initiators connected on adapter 9a: Portname Group . . . 21:00:00:e0:8b:09:6e:7b cruncher1Group . . . ... which matches the entry on the switch. If I shut down the Dell server in question, then this entry disappears from the output. And here's one LUN that should be visible: serverName> lun show -m /vol/san/cruncher1 /vol/san/cruncher1 cruncher1Group 0 FCP serverName> [I wiped out some extra spaces to make the line mail-friendly.] This leads me to think that the zoning and masking are set correctly: the NetApp sees the initiator, knows which group it's in, and has a LUN ready to serve to that group. Yet the Dell server in question can't see it. Ilya Birman wrote: > What SAN switches are you using? It possible to mask LUNS on > your switch too. Cisco MDS can discover luns and then mask > them to host. I have a generic Qlogic SANbox2-16. There is a minor firmware update available for it, so I plan to upgrade it in the next day or two. Perhaps that is one of the issues. But I don't seem to see any hooks on this switch for LUN masking. This is the switch through which all of our Dell and HP-UX servers see LUNs served from the old DotHill SAN RAID controller, and through which our HP-UX servers see their LUNs served by the NetApp. But Fast!Util on all of our Dells can't see the NetApp's LUNs: the "Fibre Disk Utility" reports "Selected device is not a disk device" when selecting one of the NetApp IDs. Thanks to all of you for your replies. Are there other tricks worth trying? Have a great day! Don Glascock -- Donald S.

Re: ip protection

a colleague of mine is in the process of buying a netapp, but is a little off-put by the part of the purchase agreement that says: [...] > If a Product becomes, or in NetApp's opinion is likely to become, the > subject of an infringement claim, NetApp may, at its option:- > > buy back the Product by paying the Customer that Product?s reasonable > depreciated value. [...] he feels that building an important piece of company infrastructure on a device which can be repossessed by the vendor after purchase is complete might be a bit of a CLM (career-limiting move). has anyone else noticed this in the purchase agreement? does it worry anyone? what's the big idea? -- Tom Yates - http://www.teaparty.net

Take a look at Intermine Filecensus. www.intermine.com <http://www.intermine.com/> . It doesn't do everything, but I think it will do what you are trying to achieve and a whole lot more. I have found that Filecensus compliments DataFabric Manager by providing more granular reporting features. Together they almost provide the Big-picture down to small-detail scaling that I would truly like to have. Filecensus will allow us to keep track of how particular shares have changed over time. Even better, we are able to view how particular file-types have changed over time. This is particularly applicable to unstructured data. By being able to figure out who and what is using the bulk of our storage, we are better informed to develop ILM and capacity strategies to deal with it. The dream?
