Testing, testing

There's something mighty strange going on at mathworks.com: although I can follow up to existing threads, three separate attempts to post a new one to toasters(a)mathworks.com in the past few days have caused absolutely nothing to appear. Please excuse this attempt to determine whether it is some aspect of the content, subject, etc. that is causing them to disappear into a black hole. Chris Thompson Email: cet1(a)cam.ac.uk

command to tell you what kind of shelves you have
by Dan Finn 30 Jul '03

30 Jul '03

Is there a command that will output what type of shelves are attached to a netapp. The closes I was able to come was "environment status shelf" but that doesn't tell me whether they are FC7, FC8 or FC9 shelves. Thanks Dan

Is there any built in utility for file compression
by Dan Finn 30 Jul '03

30 Jul '03

I don't think there is but I am just wondering if there is any built in utilities in the Netapps to do on the fly file compression as they are being written to the file system? Thanks Dan

BEA Weblogics
by Robert Borowicz 30 Jul '03

30 Jul '03

Are there any users out there using BEA Weblogics App servers out there that may be mounting the "projects" area from filers? BEA moves files around from the Admin Server to Managed Servers which may be on separate machines via its "deploy command. I'm vying to mount the domain dir on the Admin host and also make that a share to the W2K "build box". When our build guy goes to deploy apps his Ant scripts need to simply copy the .ear's and .war's to a "drop dir" which is also on the Admin host. From there we do the Weblogics "deploy" which does a number of things fundamentally which is moving the .ear files out of the drop dir and into the deploy app dirs. Anybody doing this? Thanks -Rob

Disk Hardware Questions
by Steve Evans 29 Jul '03

29 Jul '03

Some questions. . . 1. I have a DS14 shelf with 36gb disks, and FC8 shelf's with 18gb disks. Each shelf has a HotSpare. If a 18gb disk fails will it for sure use the 18gb hotspare or is there a chance it will pickup the 36gb hotspare? 2. I'm thinking about migrating all the data on the 36gb drives (including /etc folder) to fewer 72gb drives. What's the best way to do that? Can I add the new 72gb disks to the volume with 36gb drives, then start to remove 36gb drives over time? 3. Right now I have the FC connection going like this: Filer Head --> FC8 shelf --> FC8 shelf --> DS14 shelf. All of the important data is on the DS14 shelf. The FC8 shelfs aren't on support contracts, and don't have any important data at all. (mostly system images, software install files, etc). Is this a bad idea. How much risk am I putting my important data on the DS14 shelf. We're thinking about getting another FC HBA with two ports because right now we just have a single FC cable. Then I would plan on putting DS14 shelf on the Dual Port HBA (with redundant paths) and putting the FC8 shelfs on our current HBA by itself. 4. With the sysstats tool, what kind of numbers can I expect to max out on, on the Disk KB/s? Thanks, Steve Evans SDSU Foundation

RE: Error: du: failed for admin: Cycle detected

Vol copy'ing a ZCS volume to a BCS one
by Chris Thompson 28 Jul '03

28 Jul '03

What happens when one does a "vol copy" from a volume that has zoned checksums active to one that is made out of BCS (520-byte sector) disks? Do the blocks that were reserved for zone checksums on the source volume become free when the target volume is put online? Or does the latter remain a zoned checksum volume even though it is made up of BCS discs? The documentation doesn't seem to be very clear on this point, and I can't do the experiment (yet) ...

RE: Disk types

Edward, The drives in your system are X225B. They are ZCS 36GB disks. You can use the X224A, X225A, X225B or X225C which are all ZCS 36GB disks for the StorageShelf FC9.
