RE: Migrating user directories from Server to Filer
by Fox, Adam 15 May '01

15 May '01

Just a couple of ideas. What is the path on the current NT server? If it's \\server_name\user_name, then you can use the cifs.home_dir option to make the filer automagically make that share work for everyone. If it is some other path like \\server_name\Users\user, then you can create a share called 'user' just like on your NT server. OR, if you don't want to alter the server_name part and you can take that NT server name out of production, you can make the name of the NT server a NETBIOS alias on the filer (look under options cifs, you'll find it) and then the filer will answer for the old server name as well as it's own. But again, this means that your old NT box will have to go out of production or have its name changed. Just a few ideas..hope this helps. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Edward Lee [mailto:edwardlee60@hotmail.com] > Sent: Tuesday, May 15, 2001 2:43 PM > To: Toasters(a)mathworks.com > Subject: Migrating user directories from Server to Filer > > > Hello all, My company just got a 740.

You can script the change for your users using the command net user <username> /domain /homedir:\\filer\username A key trick to using the cifs.homedirs feature is to make sure that the user's home directory matches the username exactly, and also the folder has to be all lowercase regardless of how the user's name actually looks.

Origin of F330
by Bill Bradford 15 May '01

15 May '01

Can one of you internal geeks @ NetApp contact me off-list? I'd like to look up the history / origin of this F330, as it appears to possibly have been an engineering/internal/development unit (cards with revision / ECN #s, etc, tied to each major internal component, etc) and I'd like to see where it was before I got my hands on it.. Also - I thought the F330 faceplates were blue? This one is off-grey; almost like an older DEC machine... Need to find the floppy drive "cover" as well... Anyway, contact me off-list. Thanks.

snapmirror

i am snapmirroring between a 740 with 5.3 and a 840 with 6.0. the initial snapmirror went ok and i set up for it to refresh again tonight. my question is, will the target volume automatically go offline or do i need to manually offline it? i manually offlined it before and it onlined it by itself when it was done mirroring. thanks roger leonard

Incremental snapmirror targets do not need to be offline. They are read-only by default until snapmirror is turned off.

RE: ClearCase "certified" filers
by Koepnick, Victoria 15 May '01

15 May '01

Todd, As of March 28, 2001 NetApp filers are certified for the complete storage of the VOB and View databases in a Unix, Interop or Windows only Rational ClearCase environment. It is no longer necessary to have the databases reside on local disk and Rational supports placing the databases on filers. My guess is the last time you spoke to Rational folks was prior to March 28, in which case they gave you the correct information. As you well know, filers natively support both CIFS and NFS making the use of Syntax TAS unnecessary. During our ClearCase certification testing there was no performance degradation when using a filer. In fact, we typically found the performance to be better than when using direct attached storage in ClearCase environments. We are currently working on performance benchmarks in order to document the performance gains achieved. Your read of the statement in the brochure is correct. It is true that both restrictions have now been removed. Using a filer with ClearCase also makes back-up and restore much easier due to NetApp SnapShots (not to be confused with the snapshot function in ClearCase). With SnapShots, the VOB database is locked for typically only a matter of seconds (exact time will depend on the size of the VOB). The March 28th certification includes use of filers with ClearCase Multisite as well. Hope this helps clear up any questions or concerns. Victoria J.

Not to nit-pick... but what being described is the behavior of a log-structured file system (of which WAFL is one). There are many other implementations of log-structured file systems.

RE: Galaxy and NDMP
by Melvin, Grant 14 May '01

14 May '01

Hi Jordan, With a (directly attached to the NetApp) tape device you will need to run an NDMP-compliant application such as CommVault's Galaxy (or use rsh scripts) to run dump on the filer. Anyway the resulting format written to tape is in the BSD dump format which is compatible with Solaris' ufsrestore. To restore them to a non-NetApp target location you can perform a native (to Solaris) ufsrestore of the backup, but there will be a few hoops to jump through, such as, knowing where the backup images are on each tape and running the tapes through dd prior to ufsrestore. The reason for this last point is that NDMP backups even though they may cross tape boundaries are actually written as one very large (usually) data stream and therefore have to be read back that way which an NDMP restore on a filer achieves. If the data in the backup has mixed (Unix & NT) permissions then the NT permissions will be lost during a ufsrestore backup, but the data & unix permissions will be intact. Alternatively you can perform non-NDMP backups over CIFS which will capture the data + Unix & CIFS permissions. If you then restore on a filer it will restore the data + Unix & CIFS permissions. If you restore on an NT server you will get the data + CIFS permissions, but no Unix permissions. I'd go this way if you only have CIFS data or mixed data and I'd perform NFS backups if you only have NFS data. However, it really looks like the dependency is on the equipment at your disaster recovery location and in this case I'd go for filers! ;-D Hope this helps and I hope CommVault are listening.

I'll give you a 10 for good linguistics. [although, heck, I still don't agree, since there never is a copy of the data] The way I see it: Regarding log-structured, you are describing additions to standard filesystems to log prior to write (generally for reboot consistency), such as Sun's UFS w/ Logging in Solaris 7. That is not a log-structured file system. Do a quick search on log-structured file systems, and you'll see many other implementations.

The inode file is copied (checkpointed) when a snapshot is initiated, not when a write occurs. Just my two cents...

One way to look at it is to think of two ways of copy-on-write: when you are updating a block of a file you can: 1) Either write the NEW UPDATED block to a new location 2) Or move the OLD block to a new location AND THEN write the new updated block in place of the old one. Taking a snapshot with both methods involves copying the inode file BUT obviously there could be serious performance impact using the second method (for each update, the write request needs to 'wait' until the old block gets copied to a new location). Network Appliance's WAFL uses the first method which does not have any impact on performance and is (IMVHO) much more elegant.

Neil, Very early to determine the exact cause of your problems here. But taking a shot from my previous experiences with Veritas, 99 is generally when the file system path you are trying to backup is not appropriate. Could you check if the path exists or if its a directory? In case this persists, try with a different path and let me know....

RE: NetAppCertTest
by Fairchild, Peter 11 May '01

This is precisely what is being considered to deal with some of the issues raised throughout this thread. For instance, once the NetAppCP certification is achieved we could offer a variety of topical tests. Pass a test and you get a chevron to place on your NetAppCP Certification. Then, once a certain number of chevrons is earned qualification for Expert status could result. Or we could break the Professional level up as Michael H. suggests and require a certain number of chevrons to achieve it. Either way, one size would not have to fit all - it never does anyway - and the test taker can taylor the certification to their strengths, OS environment, and applications. We also see this as a possible opportunity to involve partners in the certification process. We're not there yet. First and foremost, we must develop the curriculum to support such requirements. And, creating such a testing collage is not trivial either. So for now, the two Professional level tests (NSO400 & 500) are based on the Advanced DOT Sys Admin (202), Clustering, SnapMirror/SnapRestore classes. Just like Michael H. describes, the focus is on clustering, advanced configuration, troubleshooting, tuning and optimization, with a shot or two of Oracle and Exchange taken directly from the pages of the class materials. The overall objective of the Professional Certification exams is to challenge your problem solving and critical thinking skills. Much more detail is on the NOW site. -pwf BTW, we used to call them "Merit Badges".
