Help with vif's
by Justin 21 Mar '00

21 Mar '00

Hello, We need to increase the network badnwidth to our 740. It has the bulitin ethernet port plus a quad card. The switch it's connected to is a catalyst 5500. My understanding is the vif on the Netapp is compatible with Etherchannel on the catalysts. We did the vif create on the Netapp (DOT 5.3.4r3) and combined all 4 quad card ports into one interface, it has an IP address, ifconfig shows them all as part of a virtual interface. But what do I need to do on the Cisco side? When testing this on a 520 in the past, we tried enabling etherchannel AND trunking on the ports, to no avail -- all data appears to be going through the 4th interface. vif stats <vifname> shows about 3 or 4 packets per second on e3a through e3c, and thousands through e3d. I figured that maybe it just counts the entire vif's packets on the e3d interface; is that correct? Even so, though, with heavy speed testing from multiples clients, all the data continued to go through the last port, and never broke 12 megabytes a second. I really suspect this is because we don't have the Catalyst set up properly. Can someone out there who's done this before tell me what we need to do on the cat? Do I need to put the vif commands into the rc file? Thanks in advance, Justin Acklin Oh, another thing is that almost every time we plug or unplug an ethernet port on the netapp, or even sometimes doing an ifconfig, the thing core dumps. Very annoying, apparently there is an open bug on that, which is not fixed yet according the netapp engineer I opened a case with the last time this happened.

Messages from cron_admin about daylight saving time
by Chris Thompson 21 Mar '00

21 Mar '00

We run a default raid scrub regime (01:00 on Sundays). Last Sunday we got a message Sun Mar 19 01:00:00 GMT [cron_admin]: Rescheduling raid_scrub_admin to run at Sun Mar 19 01:00:00 GMT 2000 because of Day Light Saving time change [Raid scrubbing itself ran at this time with no problem.] Moreover, every time timed tweaks the clock (we use ntp synchronisation) it again mutters. e.g. Tue Mar 21 16:04:33 GMT [cron_admin]: Rescheduling raid_scrub_admin to run at Tue Mar 21 16:04:33 GMT 2000 because of Day Light Saving time change Now all this is no doubt because next Sunday is clock-changing day in our timezone (GB), with 2000-03-26 01:00:00 GMT -> 02:00:00 BST. [American friends will no doubt be seeing this effect next week!] What I don't understand is a) Why ONTAP is making such a fuss about it. Nothing like this happened last October, but we were on 5.2.2 then, and 5.3.5 now. b) Why it always claims to be rescheduling for the current time. Maybe this is just a bungle in the message? I am expecting the messages to disappear after the clock change, but meanwhile I'm a bit bemused by it all.

DLT8000 vs DLT7000 as F740 backup device
by Chris Thompson 21 Mar '00

21 Mar '00

We have an F740 (14x18GB discs), currently without a directly attached tape drive, and are looking to add the latter. Functional experiments with a loaned DLT8000 drive (actually part of an ADIC FastSTOR) and appropriate /etc/cloned_tapes ("QUANTUM DLT8000 EMULATES QUANTUM DLT7000") were satisfactory, so I have been looking around for a DLT7000 offering, preferably 19"-rack-mounted. I am getting a lot of responses from suppliers of the form "we haven't got any DLT7000s with HV differential SCSI available, why not buy a DLT8000 drive instead? It's only [anything from 0 to 300 pounds] more". Are other NetApp users using DLT8000 drives as backup devices in production situations?

Network Appliance's current customer experience is that they do get performance on par with local disk storage already. Our current plans do not include any interoperation with the SANenergy products. -----Original Message----- From: Yael Hellmann [mailto:yael_hellmann@yahoo.com] Sent: Monday, March 20, 2000 6:02 PM To: toasters(a)mathworks.com Subject: nas storage I am currently investigating the market for nas storage.

NetApp backup recommendations
by Jeff Bryer 18 Mar '00

18 Mar '00

We are in the process of redesigning our backup system. Currently we have one NetApp F740, a variety of SUN servers and one Linux machine. The DLT 4700 jukeboxes we use are about at their limit for capacity so it's time to get some new, bigger, hardware. And the software we use is BudTool which we will soon lose support on when Legato EOL's it (we've been told we have support until at least Jan 1, 2001). So now I'm looking for both hardware and software recommendations. We use both CIFS and NFS on the filer. We want to back up the filer via NDMP with a direct SCSI attached jukebox (or jukeboxes) or via fibre and a Vixel switch (or equiv). We have been looking at AIT-2 which after some digging appears to work via direct connect although our NetApp rep keeps telling us it doesn't. We've been very happy with the reliability of the DLT drives/media and have been burned in the past with Exabyte 8mm. Some of us are reluctant to return to helical scan media. For the near future we'll be backing up to 500GBs of data/week. We have been receiving interest to expand the back ups to cover more systems on campus which could mean backing up to 3-5TB+ of data. Essentially we want hardware/software which has the growth potential. We're getting a second filer and for security reasons we need to keep it separate from our existing filer. We were looking at the SpectraLogic Gator library which would allow us to split the SCSI bus and dedicate specific drives to the individual filers. We'd prefer (need) to use 2 backup servers (one for the existing filer/SUNs, one for the new filer) so we need software that can support this. The 2 main choices for software seem to be Legato (NetWorker/Celestra) or Veritas (NetBackup). What about QuickRestore from WorkStation Solutions? That product has the advantage that the archives are compatible with tar (in the case of disaster recovery). Having software that we can roll our Netware backups into would be a plus.
