Full volume backup with Legato Networker
by Palmer, Jason (EMEA) 15 Mar '05

15 Mar '05

Hi - At present, we back up our F800 series filers with Legato Networker using NDMP and direct attached tape devices. We are looking to purchase an R200 and mirror our live data on a daily basis to this device in an offsite location and perform periodic backups to tape. We would like to backup the full volumes - the current file system plus all of the snapshots. I understand that a Dump commnd can be used to push the whole volume out to tape and a snapmirror to tape type scenario could also be used. Does anyone currently do this using their Legato backup software ? If so, could they give details of how this could be done ? I have heard that Netvault from Bakbone may have this type of functionality - anyone out there using this ? Many thanks, ----------------------------------- Jason Palmer <Storage> Messaging & Storage Implementation MCI [EMEA] ----------------------------------- [e]: jason.palmer(a)uk.mci.com [i]: http://www.mci.com/uk <http://www.mci.com/uk> -----------------------------------

RE: Multimode VIF
by Dean, Phil (ITO) 15 Mar '05

You need to take into account the port now. So a dual card has ports a and b so you do e4a and e4b to create the vif for all ports on card 4. if you had a quad port card then you have a, b, c and d as the ports so e4a to e4d.

RE: Multimode VIF
by Dean, Phil (ITO) 15 Mar '05

Drew, Got a little ahead of myself. Yes you would have to create 3 vifs, first 2 combining the two ports on each switch and then the 3rd vif to combine them all. Are you trying for a little load balancing as well? We essentially have just single vifs going to 2 ports on different switches and at most you lost a few pings when one port goes down and it switches to the other port.

unix quota and df
by Charles Bartels 14 Mar '05

14 Mar '05

Hi, I have a filer running ONTAP 7.0 connecting to a Solaris box with automounted home directories, and I'm getting different results depending on whether I have a quota in a qtree vs. a volume. If anyone can shed some light on this "problem" I would appreciate it. Thanks. -C. In the examples below, there is 35GB qtree ("home") under vol0 and a 35GB flexible volume ("home"). Both have default user quotas of 5GB. If a user's home directory is in a qtree and they do "df" on the unix box, their "partition" shows up sized to their quota. This is good; although this is *not* the way things worked pre-ONTAP 7.0 Ex. User1@unixbox> df -kh . Filesystem Size Used Available Use% Mounted on filer:/vol/vol0/home/user1 5.0G 2.0G 3.0G 40% /home/user1 If a user's home directory is in a volume, their "partition" shows up sized to the size of the volume. They need to run "quota -v" on the client to get their quota. Ex. User2@unixbox> df -kh . Filesystem Size Used Available Use% Mounted on filer:/vol/home/user2 32G 11G 21G 35% /home/user2 User2@unixbox> quota -v Disk quotas for user2 (uid 1001): Filesystem usage quota limit timeleft files quota limit timeleft /home/user2 1914808 5242880 5242880 2172 -1 -1

NFS analysis tools
by Derek Lai 10 Mar '05

10 Mar '05

Has anyone played with good NFS analysis tools? I googled about NFS tracing and saw a couple of interesting research papers. One is from Daniel Ellard and Margo Seltzer of Harvard University. The other one from Matt Blaze of Princeton University. Daniel Ellard has the nfsdump and nfsscan tools and Matt Blaze has the rpcspy and nfstrace tools. I just took a quick scan and am sitting down to read the papers. Just wondering if anyone else has looked at these and know which ones are better? Or if you know of other good tools, please share. I'm trying to trouble-shoot occasional NFS server not responding error. The filer does not appear to be very busy and only one of the 2 HP-UX servers is having this issue. Although the particular file system is our database production file system and is only pounded on by the production server. Derek

The next oil super-st0ck
by Lila Jensen 10 Mar '05

10 Mar '05

The Oil and Gas Advisory Now that Oi| and Gas has entered a long-term bu|l market, our specia|ty in pinpointing the hottest companies of the few remaining undervalued energy plays has produced soaring returns. Emerson Oil and Gas (EOGI) is an energy developer in the US "Oi| Be|t" and in Canada's most highly coveted reservoirs with generating potential of Millions per week. Symbol - EOGI Price - .12 Se|| Target - .33 = Diamond Play The value of EOGI's shares wi|l skyrocket: 1. Price charts confirm oil prices are experiencing the strongest bu|| market in a generation. 2. Natural Gas prices have trip|ed in the |ast two years. 3. With mu|tip|e projects in high-gear and the expanding production on reserves worth multi-millions, EOGI is se||ing for |ess than 1/4 the va|ue of its assets. 4. Emerson Oil and Gas specia|izes in using new technology to turn unproductive oil and gas deposits into profitab|e enterprises. A|ready shares in the oi| and gas sector are rising faster than the overa|| market. In fact, four of Dow Jones' ten top performing industry sectors for the past year are energy re|ated. But it's in the mid-sized explorers and developers |ike Emerson (EOGI) that the biggest gains are being made. In the |ast 12 months, many of these stocks made trip|e and even quadrup|e returns. Our subscribers need to pay particular|y c|ose attention to underva|ued EOGI shares, because it won't be a bargain for long. This sma|l company with a comparably small market value, is sitting on a bonanza of oi| and gas reserves - an unrecognized bonus for investors especial|y with the daily jump in energy prices. But a|| that wi|| change in a few short weeks, as these reserves move into production, bringing an exp|osion of cash that is expected to capture the attention of the market, and have an equa|ly explosive effect on the share price. What will the cash flow from these projects do for the price of Emerson Oil and Gas' shares? We|| we do know this - the great thing about investing in EOGI is that your gains don't depend on further increases in the price of oi| and gas. Even if energy prices stay f|at, or decline s|ightly, you wi|| sti|l make a very hea|thy return. Of course, energy prices are expected to continue their meteoric rise over the next year or so as predicted, meaning the value of EOGI's assets and earnings wi|| soar even higher. In that case, the reward for investors wi|| be staggering. Overa|l, we consider EOGI to be one of the |ast outstanding energy plays in the oi| and gas sector. Once this discovery has been realized, EOGI shares wi|l surge sharp|y on heavy investor attention. We have identified this discovery for immediate accumu|ation. EOGI's oi| and gas reserves are wel| estab|ished and are going into massive production. Early investors will secure optimum gains, and any additional news in this area wi|l rea||y turn up the heat, causing us to revise our targets upward in next week's bulletin.
