6.1.1 and Ultrium
by Jon Walton 23 Oct '01

23 Oct '01

Now that 6.1.1 supports LTO (Ultrium) has anyone made the plunge? I have seen some discussion in the archives, but no actual testimonies as of yet. We are replacing our library, and seriously looking at the LTO technology. We have been using direct attached NDMP with DLT7000s up until now. Regards, Jon

program to warn for over quotas
by glennm＠latticesemi.com 22 Oct '01

22 Oct '01

I have started using SWatch to monitor quotas on my F740. SWatch, The Simple WATCHer, can be found at: http://www.oit.ucsb.edu/~eta/swatch/ It is great for monitoring all kinds of system files. I use it to let me know when one of my users has hit their quota. This allows me to act on it promptly. Here is my .swatchrc file for my filer named "toaster" that is mounted on my admin system where the progam runs: ---------------------------------------------------- # # Swatch configuration file for constant monitoring # # people out of quota on praxis watchfor /disk quota exceeded/ echo mail ---------------------------------------------------- I enter the command "swatch --tail-file=/toaster/etc/messages" and it both echos the error in the window and emails me the error. Of course the user is a UID as NetApp has not setup the error so that it translates the uid to a user. I am working on the program, it is in perl, to do more for me. I have perl version perl5.005_03 and I had to get several modules to get it to make, but it wasn't to bad. The cool thing is I want to update to 6.1.1R1 so that the quota threshold can be used. Then I can have a program warn the user when they are getting close to their quota limit. It would be nice if this was built into the NetApp though. ************************************************************************* Glenn Marsh Lattice Semiconductor Corporation Unix Systems Administrator 5555 NE Moore Court CAD Engineering Hillsboro, Oregon 97124 glenn.marsh(a)latticesemi.com 503-268-8000 503-268-8136 phone - 503-268-8459 fax *************************************************************************

RE: Veritas Netbackup Database

Manny, I could not try the disaster recovery. I did move the /usr/openv/netbackup/db to the NFS mounted file system. I am not backing this up with NDMP. I just use regular "catalog backups" to the tape. When you configure regular Solaris Backup class in NetBAckup, there is an option "Follow NFS". There is no option like that for catalog backups. I wonder if the catalog backups truly work. VEritas could not answer this question, their advice was to recover. I can not afford to fail and recover the DB right now, it is something on my list.

RE: DLT 7000 question

Hallo Rahul, the problem is that the 40/80GB label on the tape package is purely marketing based on the DLT8000 drive. What counts is the type of drive and the compressability of the data. In your case the DLT IV tape is marketed as 35/70GB. Without compression 35 and with 2:1 compression 70 GB. But the compression depends on the data, which means you can have more or less. My experience with the data I back up is about 55 GB compressed, but I have already written 120 GB to one tape. For more information you should read (or download) the DLT Hanbook from www.dlttape.com, this book explains almost everything you would like to know about the current DLT tape drives and cartridges.

RE: Netapp hardware
by McCarthy, Tim 19 Oct '01

You can add 36s and 18s in the same volume. If you add them to the same RAID group, the *first* 36GB disk becomes the parity(needed for the extra stripes) and the 18GB parity becomes a data drive(they flip roles). However, it is in my opinion, better to just simply make a new RAID group with the 36GB disks. They will be taken fully advantage of (i.e. they will be 36GB disks). However, if your current volume is a Zoned Checksum volume, and you add the new 36GB(34F) disks, you will lose the benefits of the BCS disks and they will work like Zoned checksum disks. Chances are your current 18GB disks do not have the little yellow labels and are ZCS. So you may want to create a new volume with the 36GB disks unless they are BCS disks already. This is perfectly legal, it has been being done for a long time now. (mixing drives of varying sizes). The one thing to remember, the largest disk in the RAID group is *always* the parity disk, unless of course they are all the same size in the RAID group. --tmac Timothy A.

First, you really need a private network of 100 megabit or better for the Exchange server to talk to the Filer. You don't want to share traffic with everyone else. Use a crossover cable and use the IP in the path just to be 100% certain traffic is on the private network. Next, buy a copy of SnapManager for Exchange. It makes the whole thing work more smoothly.

Not only does this run great, but test restores I have done to another server are incredibly fast. It takes longer to install the OS and Exchange than it does to restore the database!

I'm running Exchange 5.5 with SP4. E2k isn't supported until SnapManager for Exchange v2.0 comes out Real Soon Now(tm). I'm running 1.1 which has NetApp Drive in it. It's a little clunky but works just fine. Our Exchange site consists of 2 Exchange 5.5 SP4 servers. One server houses all mailboxes and is attached to the Filer. The other houses all connectors like Zetafax and the IMS and is not using the Filer. The server with no mailboxes does all the verifies for the other server. Nobody ever notices when Snapshots take place. I run 2 snapshots a day. Once at noon and again at 8:00pm. I've noticed that the server with all the mailboxes doesn't have to work as hard anymore. I rarely see drive activity and the processors are rarely above 10%. It's performance is better now than it's ever been. -----Original Message----- From: Joe Luchtenberg [mailto:joe.luchtenberg@data-line.com] Sent: Friday, October 19, 2001 9:58 AM To: 'Jay Newton' Subject: RE: Good experience with Netapp & exchange Just curious, what is your particular configuration?

RE: which disk
by Mike Sphar 19 Oct '01

19 Oct '01

Seriously though, if I thought that Netapp hardware was the kind of thing that would "go up in a puff of smoke" from something as simple as an incorrect disk drive, I never would have let it in my server room in the first place. These are well-built robust machines. In my experience, they're not going to go tits up over something as basic as that. I can't envision anything bad happening worse than the disk just not being used. This isn't like a plain old scsi bus where connecting a device incorrectly can short the whole bus out (I've scene a couple of sparcstations die that way). These things are designed to be hot-swappable. If the disk is for some reason the wrong size or manufacturer or type, it will a) probably not even fit in the shelf, or b) just not get recognized by the filer. If there's some great risk of plugging in an unknown disk, I'd like to hear about it. -- Mike Sphar - Sr Systems Administrator - Engineering Support Peregrine Systems, Inc. -----Original Message----- From: Jim Harm [mailto:jharm@llnl.gov] Sent: Thursday, October 18, 2001 4:27 PM To: toasters(a)mathworks.com Subject: RE: which disk Thanks, I will. ... not.
