Re: Hidden commands
by Jim Ripley (49er Fan) 28 Jan '00

28 Jan '00

Hi, I wanted to state that "wrfile" will blow away whatever file you are issuing it on as soon as you execute it. So please be careful. In the past we have used wrfile to add a line to like the /etc/rc file or /etc/hosts or whatever but to add that one line we have had to re-enter in all of the original data by hand and then add the new line we want since wrfile blows away the contents of the file. That is why Netapp does not endorse the use of the rc_toggle_basic commands unless we provide training on them like in the 101 or 202 clases, or under the guidance of the tech support or escalation groups.

filer in Unix / NT environment
by Mike Hollyman 27 Jan '00

27 Jan '00

We are a primarily Unix environment and are placing a netapp in for a shared filesystem. We are told that the Samba PDC will not work to authenticate the filer in CIFS. We've also tried Sun's NetLink software that emulates a PDC with no luck. Is there any way to get encrypted passwords to the filer without using a "real" NT server PDC? Mike

Hi Bud, You might want to check out the following site. http://www.performancecomputing.com/features/9912sr.shtml It lists a variety of tape technologies and specs and when some of the new stuff is slated for release. As far as who will win the tape technology wars, I won't even pretend to know, but what I'm seeing out in the real world right now, is DLT7000/8000 and AIT-2. I personally think that Exabyte destroyed their credibility with the first version of Mammoth. It was something like three years late. They made announcements like every three months,for years. It's coming, it's coming. When it finally did show up, nobody gave a damn, because everyone had bought DLT by then. I know a lot of customer's are waiting for Quantum's SuperDLT due out at the end of this year, because they are already using DLT and have found the DLT7000 to be reliable, once Quantum improved their "dropped leader" problem. Sony's AIT-2, also has a good rep and is being made available in more of the various libraries. I think one of the real determining factors is the number of library vendors who choose to support the various tape technologies. Because of the massive growth in data, fewer sites are using stand-alone drives and more customers are choosing libraries with backup software to manage them. Right now the majority of library vendors I know about, all have at least DLT support and more are also starting to offer AIT-2. That is one factor in determining the future.

Legato backup revisitted
by Christopher Algar 27 Jan '00

27 Jan '00

Struggled though a barren period of no filers................but I'm about to get an F760! I've used these before, but this will be new to this company. At the same time we are considering a backup solution. Actually that's one of the main reasons I was able to get the filer in - snapshots and all that good stuff. The standard for our associated companies is Legato Networker. I've read through the threads from early last year - NDMP not yet, ACL's only via NT etc. etc. So, what is the latest? Would appreciate opinions on the following:- If I want to preserve NTFS permissions then should the Legato server be on NT? If so, Is Legato reliable/stable on NT? If it works and is a lot cheaper then OK, with have the people to run either. For information, will will be at ~ 750 G, probably 2/3 rds NT data, the rest an eclectic variety of unix(s) and linux. Thanks in advance for all input. Chris Algar

Win200 and Netapp Clustering
by John Gaines 26 Jan '00

Does anyone have any experience with the way Win2000 handles a failover of a Netapp cluster? Does the Client have to re-connect like a NT 4.0 box does? -- ______________________________________________________ John A.

RE: HPUX 10.20 problems
by Fox, Adam 26 Jan '00

26 Jan '00

A good tool for Tech Support people (HP or NetApp) is a network trace of the transactions. This is especially good if you have one client who is working and one who is not. Taking a packet chase of each and comparing them tells Support people (and possible engineers) a lot of useful information. If you can't take traces from the client side (Solaris and SGI have snoop, HP I don't think ships one), you can always try pktt on the NetApp. This produces a TCP dump-format which some utilities can covert to other formats (snoop, sniffer, etc.). If you do decide to open a ticket with NetApp on this, getting some kind of packet trace will be very useful. A properly-done trace can tell us if the client is doing something that the server doesn't respond to properly, or if the client isn't generating a request or something else. Another bonus of getting this is it helps Engineers of any vendor figure out what's going on and possibly with reproduction efforts.

NOW is using "style sheets," which set attributes for font, tables, body, etc. However, we've identified a problem with our style sheets and that why some folks are seeing black text on blue bars.

HPUX 10.20 problems
by Graham Knight 26 Jan '00

26 Jan '00

We have a problem with HP-UX 10.20 clients. Occasionally they stop getting NFS updates from our NAC servers. For instance, you might create a file, but when you attempt do an "ls" on the file it does not appear. But if you log into another system and do an "ls" it is there. The only solution we have found is to reboot the HP. HP is no help. Their tech support continues it's downward spiral. At one point a few years ago we had the exact same problem with HP's and solved it by installing 4 or 5 patches. It was just dumb blind luck that I happened upon an HP tech who knew what he was doing. Now those patches are out of date, and the problem has popped up again. My hope is that someone on the list knows about this problem and can give me a list of patches they installed to fix it. Any input would be most appreciated. Thanks, Graham
