Backups with DUMP command
by Clawson, Simon 18 Oct '00

18 Oct '00

Hi! I am currently having a problem with Budtool. We have just had a F760 head put in, on an evaluation, to replace our F520. We have Budtool installed and running OK for he F520. However, with the new filer in place, Budtool fails to run. I have restarted the daemons and get an error message "Invalid License Password" I am guessing that this is because the new filer has a different numerical host id. I am told that Legatto are being quite diffiult where Budtool is concerned, and we made a decision to lapse support this year due to the EOL of the tool and the desire to replace it with Veritas. With this in mind, I'd like to be able to use the Dump command for now, until I get a solution for Budtool. Has anyone had experince of multiple tape backups with dump? Can it be done? Can the NetApps control the Jukebox? Any advise would be greatfully recieved?

Hi Simon, You are correct in that Budtool fails to run because the new filer has a different host id, however you should be able to get Legato to move the license from one host to another for you. In answer to the question about controlling the robotics from the filer, the answer is no. If the library you are using can be setup in sequential or stacker mode, you will be able to use it, with the native dump and restore utility, but for true robotics control, you do need a 3rd party backup package. I don't know if you are aware of this, but there are several packages that are certified with the filer, including Veritas. The others are Workstation Solutions, www.worksta.com <http://www.worksta.com> , Commvault, www.commvault.com <http://www.commvault.com> , and Syncsort, www.syncsort.com <http://www.syncsort.com> . You might want to check them out, as they all offer different features and benefits, and are cheaper than Veritas. Hope this helps. -----Original Message----- From: Clawson, Simon [mailto:simon_clawson@mentorg.com] Sent: Wednesday, October 18, 2000 3:21 AM To: toasters(a)mathworks.com Subject: Backups with DUMP command Hi!

Considering NetApp
by David Murphy 18 Oct '00

18 Oct '00

Is there an unofficial NetApp faq available? I'm considering NetApps for the first time (as backend storage for Sun/Solaris webservers), and could really use a brief roadmap/glossary on what modules a filer comprises, how the availability features compare with OS failover, filesystems, snapshots etc. basically the truth, as compared with the marketing blurb ;) Any pointers would be greatly appreciated. -- When asked if it is true that he uses his wheelchair as a weapon he will reply: "That's a malicious rumour.

Yes, it's called "pktt".

Trivia: what do the splodges on the LCD represent?
by Chris Thompson 17 Oct '00

17 Oct '00

During normal operation, the LCD on an F7xx displays each second a number, which I believe to be the number of NFS operations in the last second, followed by a row of 0 to 10 splodges --- at any rate, I have never seen more than 10. The hardware installation guide refers to this as "a bar graph" but doesn't go into details. What is actually being measured here? The number of splodges is correlated with the number, but not very strongly, and the number has a far larger dynamic range.

Filer Backup w/Networker
by dmaloy＠atomaintl.com 17 Oct '00

17 Oct '00

I have two 740's which I would like to backup. We are currently using Legato Networker for our backup solution and the backup server is a UNIX machine with a locally connected DLT tape library. Within Networker, I have to specify which filesystems to backup and when I specify the volume on the filers, my backup log reports that the backup size was almost triple the size of what the actual data size was, reported by using the "df" command. I have a feeling that it is also backing up the .snapshot directories for ea. vol but not sure. Is there a way to ensure that these directories are not included in the save set? Will a "-.snapshot" line in the client setup fix it? Don Maloy Sr. CAD Administrator Atoma Latching Systems 19888 Haggerty Rd Livonia, MI 48152

Re: Backup solution.

A word of advice on the Spectra Logic Gator. We have had one for about two months now and it is not yet a mature product. (but it is making progress) In that time I have had to upgrade S/W in the unit at least four times. One upgrade (done at the recommendation of Spectra Logic) turned out to not be compatible with the EC level of my H/W requiring a couple of RMAs. Today it is still possible to confuse the unit if care is not taken. (what else can you expect from a product running Windoes CE?) Having said the above. I like the idea behind the gator and believe that in time Spectra Logic will get the kinks worked out. The ability to logically partition the unit as well as the future possibility of backing a netapp over FC-AL makes it very appealing. But you might want to give the unit a little time to mature first. In my experience the fastest way to back up a filler today is direct attach SCSI. FC-AL is not supported till OnTap 6.x which is still only early access. (I will not run early access code on production fillers) Gig ethernet may look appealing but I cannot see how placing an ethernet layer between the NetApp and the tape drive is going to speed anything up. There are two fundamental bottlenecks for backups, the speed of the tape drive and the load on the filler. Adding more stuff in the middle cannot speed things up. While we are on the subject, I have an upgrade the "ndmputil" package that supports large tape libraries and includes a tool to retrieve drive & tape stats from AIT tape drives. I hope to get the upgrade to NetApp for posting on NOW as soon as I get the documentation updated.

Legato's NDMP support currently is not worth considering, and Veritas hasn't been forthcoming in working with us.
