RE: F840 or F880
by Joe Luchtenberg 14 Nov '01

14 Nov '01

F880 dual-CPU is for performance purposes only. It is not for redundancy and does not enhance availability. There are some other enhancements, such as the PC card boot. If you need clustering for high(er) availability, F840c or F880c both deliver. Considering you already have the F840, it would seem to me that an F840c is the better option from an investment protection perspective. I.e. you're not going to get full purchase price (by any stretch) back as trade in for your F840 if you go with the F880c.

Does anyone have any good advantage point to this type of upgrade that would justify the cost. Jennifer )

heavy CPU and NIC usage, not so heavy ops usage
by Todd C. Merrill 14 Nov '01

14 Nov '01

Funny thing has started happening of late. The CPU is pegged or nearly pegged on an F760 running 6.1R1, but yet the ops usage isn't all that high. The NIC card seems to be doing an incredible amount of work (I've seen it in the 90-95% range over about a minute sampling time.) No errors or anything unusual on the port on the Cisco switch. A decent amount of network output, a goodly amount of disk reads, hardly any writes, a low but not disasterous cache age, not too many cp-from-cp points, etc. I'm stumped. Any ideas? Just plain overloaded? filer00*> ps -h Process statistics over 365.789 seconds...

RE: F880c
by Joe Luchtenberg 14 Nov '01

14 Nov '01

I presume you meant "arguments." ;-) (Also, did you mean F740c or just a stand-alone F740?) Given the dramatic price difference, it simply depends on the scope of your requirements. - do you require a single platform that scales to 18TB? - what about performance? - (I assume you meant F740c, but just in case you are comparing clustered and non-clustered platforms...) what about cluster failover high availability? The lotta-little-filers-versus-a-coupla-big-ones issue can be reasonably argued on both sides focussing on many issues. - manageability/ease of administration - cost - performance - availability - complexity - etc. With either platform you get the full range of capabilities associated with Data ONTAP -- WAFL, SnapShots, available support for multi-protocol environments with SecureShare single-instance data sharing, available value-added features including SnapRestore, SnapMirror, SnapManager for Exchange, Global Data Fabric management capability with Content Director/Content Reporter, etc. <End of NetApp commercial> FWIW, the F740 is an alpha-based platform. The F880c is built on an Intel SMB architecture. The F8xx series is the latest generation from NetApp, and it is reasonable to expect that they will be available and supported long after the F740 model has been retired. HTH.

Permissions wiped out on NTFS qtree
by Allen, Pat 13 Nov '01

13 Nov '01

Hi everyone, I need to get some help from you folks to help diagnose a problem that I'm working on with Net App. Here's my configuration: two filers running in a cluster under 6.1R1. We are running NFS and CIFS on the filers. All of the servers in the NT domain are running NT 4.0 - we don't have any Win2K servers. Here's the problem: We have seen situations where the entire NT ACL on a qtree is deleted. I've been able to reproduce this using two Windows 2000 computers. (They both happen to be running SP2.) Here are the steps to reproduce it. I apologize for the number of steps but I want to make sure that I got all the details down. 1) Create a new NTFS qtree. I called mine PatsTest. 2) Share the qtree with standard share permissions (Everyone=Full Control) 3) Create a new global group in the domain. (Again I call mine PatsTest.) 4) Add one user to the global group; this user has no special domain privileges. On the first Windows 2000 workstation: 5) Log into one of the Win2K workstations as a domain admin. 6) Add a bunch of folders and files to the qtree. 7) Open network neighborhood and then open the filer. Open the property panel for the NTFS qtree. 8) Click on the security tab and set the permissions as follows: Remove the Everyone group Add Domain Admins with Full Control Add the group from step #3 with Full Control Make sure that you go to the Advanced tab and select "Reset permissions on all child objects..." 9) Verify that the NTFS Owner is set to the Administrators (Filer\Administrators). On the second Windows 2000 workstation: 10) Log into the second workstation as the non-administrator user from step #4. 11) Open Network Neighborhood and then open the filer. 12) Open the property panel for the NTFS qtree and click on the security tab. 13) Verify that the NTFS permissions are set as listed in steps #8 and #9. 14) Go to the Advanced tab and select the "Reset permissions on all child objects..." (You don't need to actually change anything but doing that doesn't change the outcome.) 15) After changing the permissions, an error box will appear stating "Unable to save permission changes on xxxx on yyyyy. Access is denied." where xxxx is the name of the qtree and yyyyy is the name of the filer. 16) You must click Cancel at this dialogue box. Close the property panel for the qtree. 17) Open the property panel for the qtree again and notice that there is no security tab! Back on the first Windows 2000 workstation: 18) Open the property panel for the qtree and click the security tab. 19) There are no permissions listed! 20) You must go to the Advanced tab and reset the owner before adding the groups again. What I've determined: * This ONLY happens if you try to change the NTFS permissions at the qtree level. If you try to change the NTFS permissions at the folder or file level then everything works OK. * This problem occurs when a user who has sufficient permissions BUT IS NOT THE OWNER tries to reset the permissions. If I added a step 13.5 to the scenario above where the user on the second workstation took ownership of the qtree before changing permissions, then everything works OK. OK... Has anybody seen anything like this????

Re: Permissions wiped out on NTFS qtree
by Andrew Yee 13 Nov '01

13 Nov '01

Hi Allen, I've seen that happen in our NT 4 Domain between NT 4 Servers and Win 2000 Pro PCs. This is probably somewhat unrelated to your Win 2000-to-Win 2000 problem. When I use a Win 2000 machine (with Domain Admin rights) to modify NTFS permissions on an NT 4 Server, the permissions persist fine. However, when I use the NT 4 Server to verify the permissions, I get an error message saying that the permissions are incompatible due to a conflict between NT 5 permissions and NT 4 permissions. I usually end up retaking ownership of that directory via the NT 4 Server and having to re-create the now wiped-out NTFS permissions. I have not tried this on our Filer as of yet. >>> "Allen, Pat" <pat(a)mbari.org> Tuesday, November 13, 2001 9:13:46 AM >>> Hi everyone, I need to get some help from you folks to help diagnose a problem that I'm working on with Net App. Here's my configuration: two filers running in a cluster under 6.1R1.

I was just wanted to post a quick thanks to all who replied to my post from a few days ago. It appears that I may have been a bit vauge in my request. I got a wide range of responses from 'RTFM' to some very detailed and helpful examples of how others are using SnapManager for Exchange in their own environments. To all that responded "Thank you". I appreciate the input. I feel much more confident moving forward with our plans with our filer and SME. Thanks again. - Scott W.

RE: managing snapshots with Exchange ...

Hi Scott: We use a Task Scheduler job under Win2000 to run snapshots. We snapshot once a day, and defer the verification until off-business hours because it's such a resource hog. We back up the snapshot directories as normal file systems, WITHOUT USING our backup software's Exchange agents. We typically keep 3-4 snapshots on the filer at a time. Through the command-line options of snap manager, you can tell it how many snapshots you want to keep. This is a newer feature than from 1.0... Let me know if I can answer any other questions. -john John Witham Senior Data Networking Engineer Takeda Pharmaceuticals North America, Inc.
