by soeren.daehnrich＠previewboard.com 22 Sep '05

22 Sep '05

Hi, i have a Problem with a FAS270, the Ontap Version is 6.5.5P9, but the Raidlabel is from Ontap 7.0. In which Mode (maintenance or other) can i use the command "revert_to 6.5.5?" I can't find the command in the Maintenance or the CFE Mode. The FAS270 is down and halted. Thank You Soeren Daehnrich PS:Sorry for my English.

RE: sybase

Hi Frank, We are running our sybase DB's on netapp filers. Some figures: Sybase is running on a Sun 6800 with 14 CPU's and 14 GB of RAM. We are running two sybase servers on that hardware: * PeopleSoft HR: 139 GB data and 5 GB log (grow 18 MB/day) * Clinical Workstation: 545 GB data and 21 GB log (grow 250 MB/day). * +70 smaller DB's. We have +1000 concurrent users on the system. We use FC on a FAS960c for the data and FAS3020c for the logs. We have decide to split data and logs for very specific disaster recovery raisons. We want to do a load DB of one DB (standby) without performance impact on the other DB's (production). For the sybase, we work with raw devices and use Veritas for multi pathing. For mor info, You can always contact me.

Tuning SnapVault perf over WAN links
by John Stoffel 21 Sep '05

21 Sep '05

Hi all, We're running snapvaults across a WAN link and we'd like to make sure we're getting the best performance possible. Both for the initial transfer, and for the followup snapshots which sync up the systems. All the systems are running OnTap 7.0.1 currently. The source filers are F960s or F270s, so they've got plenty of oomph. The network is all Gigabit on the LAN side. We have a WAN setup with 45mbit/sec and 90mbit/sec links between various sites. But the latency is on the order of 90ms, which means that we want to have a TCP Window Size of around 2Mb to keep up streaming performance. I've been looking around, but I don't see anything which explicity addresses LFN (Large Fat Network) WAN links like this under snapvault, esp when there's a large latency in the loop. Does anyone have any pointers on what I can do to: 1) tune the TCP stack for better performance 2) monitor the Network settings (internally, I know I could use ethereal or some other external snoop tool). 3) get better stats out of snapvault for how the transfer is going, and how long it's going to take to Quiesce snapvaults. I've had some which are going on 300+ hours! 4) What other people are doing in this situation to monitor and control large numbers of snapvaults (we're doing per-qtree) across WAN links.

Incremental NDMP backup after volume migration.
by Roger Stansfield 20 Sep '05

20 Sep '05

I asked the following on the NOW Backup Community Forum but I haven't yet had any reply. Can anyone help, please? I have upgraded to ONTAP 7.0.1R1. I shall use ndmpcopy to copy vol2 to a new vol2flex- there's enough space. I shall remame vol2 to vol2trad and vol2flex to vol2. vol2 contains files accessed by CIFS. We run nightly ndmp incremental backups (Netbackup, Windows). 1. Will the backup after the volume renaming be as normal (because most file modification times are still prior to the last incremental) or will we get a backup of everything (because some archive status bit shows none of the files have been previously backed up)? 2. To migrate, I may, in the event, do a level 0 ndmpcopy on a live system followed by a level 1 ndmpcopy with the volume restricted. Does this make a difference? 3. Later, I shall handle vol1 which has files accessed by both NFS and CIFS. Will the situation be different on this volume? 4. If a "level 0" backup is going to be produced, is there some way of avoiding this or are there good reasons why we should want to get a full backup? -- > Roger Stansfield, > Rowett Research Institute, Bucksburn, Aberdeen, AB21 9SB, Scotland, U.K. > Telephone: 01224 716677.

RE: Windows Explorer directory size discrepancy with home directo ry.
by Kimminau_Eric＠emc.com 19 Sep '05

You are seeing user quotas, not share/export/qtree quotas. You need a qtree quota to limit the qtree to 2GB. User quotas define how much of a system/export/share/qtree quota is available per user. The advantage of using a qtree over a directory is that quotas can be set on a qtree and oplocks can be enabled or disabled dynamically on each qtree. For reference: http://ecserv1.uwaterloo.ca/netapp/man/man1/na_quota.1.html http://teaparty.mathworks.com/toasters/0309.html http://teaparty.mathworks.com/toasters/2692.html http://www.mewburn.net/luke/src/quotarep # quotarep -- # parse the output of a NetApp's "quota report" and highlight # which entries may or do exceed their maximum. # (default is to highlight entries within 10%) -- ---------1---------2---------3---------4---------5---------6---------7 Eric Kimminau Email: Kimminau_Eric(a)emc.com Senior Corp.

Windows Explorer directory size discrepancy with home directory.
by Maglinger, Paul 19 Sep '05

19 Sep '05

Running a 740 filer with Ontap 6.4.5. I have users that are mapped to their home directories on the filer. We have 2 GB quotas on the home directories. When one of our users clicks on her mapped drive, it shows that 12.8MB are used and 1.98GB are free in the Windows Explorer pane. When I check it as another user on another system, it says that 4K is used and 1.99GB is free in the pane. If I right-click on the folder in the home directory and bring up the properties of the folder, it shows that there is 1.51GB of data in there. What's causing the discrepancy?

Unified Accounts
by Ryan Kather 19 Sep '05

19 Sep '05

Greetings, I would like some input into how others here are doing multiplatform account management with their NetApp devices. I have an idea of how I would like to proceed, so if anyone would like to sanity check my thoughts and provide some insight I'd greatly appreciate it. I am looking for a way to unify our authentication services at my employer. Presently we have clients authenticating via Windows PDCs, NetWare eDirectory (Novell Client), and UNIX PASSWD file. In evaluating Novell's new Open Enterprise Server line, I realized a big potential of the Linux version of this is to consolidate directories. For example, I can use Samba to emulate a PDC, NCP Server to provide Novell Client services, and eDirectory via LDAP for UNIX authentication. Which brings me to my nifty network layout. I would like to use OES on Linux to centralize all of this. I would have a Samba domain with the NetApp devices able to join (supposedly). I would configure the CIFS and NFS exports on the NetApp devices. Lastly, I would mount the applicable NFS exports on the OES server itself and reexport them with NCP Server as Novell Shares. To Windows clients it looks like they're in a domain and logging in with their eDirectory IDs, to UNIX clients their login works just like passwd except it's over LDAP(TLS) with their eDirectory IDs and mounted NFS paths, and lastly to the existing Novell users who are not in a domain the NetApp filers would look like traditional NetWare volumes. OES does the magic rights translations to convert everything to Posix (I'd have to check about ACL on Posix). So the key barrier I see involves how to train the NetApp devices to correlate Windows SIDs to UNIX UID/GID. This way a user could access their same data regardless of platform with the same eDirectory login. I know this is possible with Mixed mode security and the usermap.cfg. The questions: -------------------- Is this the optimal way to manage this? Would a simple usermap.cfg entry like THEDOMAIN\* == * do the trick, or are things more complicated then that? Has anyone used a Samba PDC to manage NetApp devices? Thank you for any information anyone has Regards, Ryan -- The more we disagree, the more chance there is that at least one of us is right.
