RE: Attaching a Netapp to Fibre Tape drives in a SAN?

Hi, > It can be, considering that often it is cheaper to buy the > hardware to set up your own dedicated backup LAN than buying > the hardware to set up your own dedicated backup SAN. In fact NetApp is working to offer solutions in both areas. The FC SAN area discussed earlier today and via the Open Storage Networking (OSN) Initiative that was announced at N+I last week: http://www.netapp.com/news/press/news_rel_20000510.html If you were at the show you would have seen a pre-production ATL P3000 running an NDMP tape server within the library with backups of a GbE connected filer via a Cisco & Foundry GbE/100bT switch. The tape library was connected to the switch(es) via 100bT. Yip, network attached tape libraries will soon be with us.

It can be, considering that often it is cheaper to buy the hardware to set up your own dedicated backup LAN than buying the hwardware to set up your own dedicated backup SAN. But if you have a pre-existing SAN and a Vixel switch, NTAP's new solution seems ideal. Bruce

RE: Attaching a Netapp to Fibre Tape drives in a SAN???

Hi Jason, This configuration is planned to FCS on the F760 (and possibly the F740) in early June. The configuration will be tightly managed and sold by our tape library partners, ATL & Spectra Logic. This is currently being tested by NetApp, ATL, Spectra Logic, Legato & Veritas using Data Ontap 5.3.6 (expected FCS 5/26/00). We are working with our partners to get all the relevant docs available on our perspective web sites in this timeframe too. My questions to Netapp are: 1) Is this possible? Yes, with a limited configuration, ATL P1000 or Spectra Logic 10000F and Vixel 8100 (with NAS firmware). 2) How would the Netapp log into the switch? As a Loop or Fabric? The NAS firmware in the 8100 provides "Loop Emulation" so each filer sees FC-AL and believes it has a locally attached tape library. 3) What is the solution for backing up a Netapp directly to Fibre tape drives? NDMP-compliant applications such as Legato BudTool & Veritas NetBackup are being certified. However, rsh dumps via cron will still be supported. 4) What is supported? As Darleen points out, check the http://www.netapp.com/news/press/news_rel_20000202.html announcement.

Hi Jason, Yep we do, with a few differences. The solution that has been tested and certified is as follows. NetApp filer Vixel 8100 switch ( with special NAS firmware) Veritas or Legato software Spectralogic or ATL libraries The press release announcing this can be found at www.netapp.com/news/press/news_rel_20000202.html also if you check the Spectralogic web site and the Vixel web site they have more information.

Has anybody had any thoughts or done any testing with the following configuration? Basically connecting a Netapp into a SAN for backups not storage.

Veritas Netbackup and NDMP Solaris or NT Netbackup Master and several Media servers Connect the Netapp into the swtich with the extra fibre connection.

We also have the same problem with this release of Ontap and Netbackup v3.2. According to Netapp the cause of this problem is a faulty Java Class (Garbage collection) which NDMP uses. This should also be the reason for the problems with Ontap 5.3.5xxx, where the problem got critical and backup stopped working. Netapp recommended us to switch to Ontap 5.3.5R2P1, where the NDMP-BUG is (hopefully) fixed. regards, Klaus Micheler Infineon Technologies DC

storageshelf questions

Has anyone successfully mixed FC8s and FC9s on the same FCAL loop? We currently have four FC8s connected to our F740, one FC8 not connected (no drives in it), and two FC9s just arrived (we ordered FC8s, but tech said that they'll co-exist just fine). The instructions indicate that when you connect one FC9 to an existing loop containing FC8s, you have to make it ID-0. What about the second one? (I'm assuming that we just make it ID-1, but the documentation isn't clear.) I'll probably just price what NetApp would charge to just upgrade your existing FC8s to FC9s. I'd rather have a homogeneous set of shelves, honestly. Also, I heard a nasty rumor that the F740 actually maxes out at 7 trays worth of (18Gig) disks. Is this true or can we order our 8th tray without worries? -- Rob ---------------------------------------- Rob Windsor E-Mail - mailto:rob_windsor@adc.com Senior Unix Systems Administrator Voice - phone:972-680-6919 Computer Services Fax - phone:972-680-0370 Broadband Access and Transport Group __o ADC Telecommunications _`\<,_ Richardson, TX 75082 (_)/ (_)

RE: Recovering files using NetApp

Hi Akhilesh, You need to be running the ClientPak for NetApp on your filer, and if you are then, then you would use a special na_recover command from the command line ( The GUIs do not presently work, with this version from Legato) The na_recover command ensures that the files retain their original permissions or ACLs when they are recovered. If you need to know more about the ClientPak for NetApp, please check out Legato's web site. -----Original Message----- From: Akhilesh Kumar [mailto:akumar@egreetings.com] Sent: Wednesday, May 10, 2000 3:16 PM To: NetApp mailing list Subject: Recovering files using NetApp Hi Gurus, I am using Legato Networker to back up a F720 filer.

What are effects of Virus (computer virus) on a "ntfs qtree" and on a "mixed qtree". Thanks to all who responded to my question on "Raid Groups". I am going with 12+1, 12+1,6+1 with 2 hot spares. (Totally 35 drives). Thanks Sateesh Mucharla National Semiconductors - CA.
