Re: Quickest way to move data.

BareMetalMove, or whatever it's called now, worked very well a year or so ago and I imagine that your SE's can help you set up something along those lines with a back-to-back 100BaseTX-fd connection. FDDI also works quite well. I seem to recall that we got about 5MB/s from a 1400 to an F330 over a FDDI connection. I'd be surprised if you couldn't get a fair bit closer to wire speed between an F540 and an F740. It tooks us just over 1hour 20minutes to move our 20GB of data from the 486-based filer to the P90 - which I recall blew me away totally. Now, I'm presuming you've got a maximally configured F540 (in terms of disk) which ISTR is about 300GB. 300GB, at 10MB/s (wire-speed on 100BaseTX-fd) takes about 9 hours. If it goes at 5MB/s it takes 18 hours. If you've got less *used* disk-space it takes less time. ISTR that BMM makes a verbatim, swizzled copy of the filer so I don't think you lose snapshots or anything. The only thing to be careful of is the DOT version installed (being alpha - should be okey) on the new filer, and the network interface references in hosts and rc before booting it and getting going. Plus there was some slight untidiness in the final part of the BMM when I used it a goodly while ago - I think it needed to be booted without the contents of NVRAM or somesuch, which was fine because it wasn't actually normal fs data in there, though I'm probably misremembering totally now. Doing this stuff over a normal network, or with either filer up and serving is a different, and slower, matter. You'd probably need to use ndmpcopy or something and that's a bizarre fish from what I've experienced. On Sat 12 Jun, 1999, "Shaun T.

You might be able to do that - but I'd keep the F540 integral so it *can* be fixed, and avoid importing weird configs into the machine your going to use to tide you over until the normal box is working again. > > Also, if it's fibre-channel only, how am I supposed to attach my > scsi-based DLT jukebox, so I can continue to back up the replacement filer > via NDMP? Is there a scsi port on an F740, just for use by a tape drive? SCSI connections to tape drives are still there. Upto two controllers with two drives on each tape chain IIRC. Fibrechannel tape controllers are not common yet, so your DLT will be supported for a goodly while yet. > > -ste > > Work: (908) 582-7629 Pager: (800) 756-1133 Cell: (201) 310-9941 > >-- End of excerpt from "Shaun T.

It depends on the environment. You'd be surprised the number of companies that have poor internal unix security, because they don't want to invest the time and money on something they may never need. Many IT professionals fail the understand the cost of bad internal security.

RE: NFS ACLs
by Chen, Ray 11 Jun '99

11 Jun '99

I believe IRIX does allow you to set ACLs over NFS if you're running a reasonable version of Trusted IRIX. But I'm not sure if it uses the same proplistd side-band protocol or if they rolled their own and both the client and server have to be running SGI Trusted IRIX. Also, from what I gather, various draft versions of Posix ACLs had some reasonable significant differences so without detailed information on the exact ACL semantics, I couldn't say how similar the Solaris, Digital, and IRIX semantics are. For NFS v4, the situation is further complicated by the fact that HPUX ACLs and NT ACLs are different as well.

> Oops... the version I posted earlier was not the right one. > > Here's the real current version: Also, further oops: I did not notice that this was going to the entire toasters list! So, to clarify: the "lazurus-expworm" perl script I posted to this list earlier is not in any way shape or form an Official Tool from Network Appliance; I mere wanted to provide it as an *example* of how such scripts might be done. Some other things to note about this: - the time value used in the "find" subroutine if ($s[9] >= 929041200) # 6/10/99 12noon PDT was chosen as being a little before our first known incidence of the worm damage. You'd probably want to adjust this for your own situation. - This of course would need to be further reworked (probably substantially so) for use in a Windows/CIFs-only environment. Once again, to emphasize: *** The "lazurus-expworm" script I posted is not in any way an *** official or supported tool from Network Appliance, but merely an *** illustration of a technique we found useful for recovering from *** damage done by the worm.

Needless to say, persons who read mail on Windows systems would be well-advised not to open that attachment. Brian

Virus warning

10 Jun '99

I have just been sent a copy of the W32/ExploreZip.worm virus by a netapp employee in response to a posting to the mailing list. Do not open any files with an attachment called zipped_files.exe For more details see: http://vil.mcafee.com/vil/vpe10183.asp the virus has similar characteristics to melissa. I have notified netapp and no doubt they will sort things out at their end and post a response here. [sigh] Chris -- Chris Good - Muscat Ltd.
