RE: disk_fw_update

Thanks for the responses everyone! Jeff Sloan wrote: Yes there is definitely spin up issues with some of the old firmware on the 18G FCAL disks. Upgrading the firmware to the newest releases is the right move. Doing it individually is a very safe method up updating them, and definitely desirable, as you've had a few disk fail on you. I would like to note this is just on the older firmware revisions on the 18G drives. (hence once you finish upgrading you won't have to worry about this repeating itself). In regard to your current situation, The solution is to reboot the node that is reporting the mailbox disk error. We have a workaround that allows you to avoid rebooting, but it's only for ONTAP 6.1X and above. Did you halt the second system when upgrading the firmware? There's a specific process to upgrading the disk firmware on a cluster pair. You can review that process here: http://now.netapp.com/NOW/knowledge/docs/ontap/rel601r3/html/sag/fw_up5.htm… Cheers! :-) Jeff > -----Original Message----- > From: Geoff Hardin [mailto:geoff.hardin@dalsemi.com] > Sent: Thursday, October 18, 2001 1:40 PM > To: Sloan, Jeff > Subject: Re: disk_fw_update > > > Jeff, > The cluster is running DOT NetApp Release 5.3.4R2.

disk_fw_update

filer1> cf status filer1 has detected a mailbox disk error, takeover of filer2 disabled I have just finished upgrading the disk firmware on filer2. I had turned off clustering per the disk_fw_upgrade instructions prior to upgrading the disks. Once I had finished, I tried to turn clustering back on on filer1 and received the error message above. Any idea what's going on? filer2 does not report any errors on cf status. Thanks for the help!

RE: quotas file
by Honeycutt, Michael 18 Oct '01

Thats how I do it also. For instance, if you want to use a scheduled task to do a quota off/on instead of resize, you could say: This would be first cmd file- rsh filername -l username:password -n quota off volumename call c:\foldername\filename.cmd This would be second cmd file- rsh filername -l username:password -n quota on volumename -----Original Message----- From: Jordan Share [mailto:iso9@phantasticant.com] Sent: Thursday, October 18, 2001 2:23 PM To: Grey, Michael; toasters(a)mathworks.com Subject: RE: quotas file Well, I can't help you with most of your questions, but I can tell you how I rsh from win2k to my filer.

RE: quotas file
by Berry, Grant 18 Oct '01

Hi Michael. Sounds like you have quotas set up well. RSH from an NT client is pretty easy to set up and then make a batch file for. This is what I do... 1) Just type in "rsh filername command" eg: rsh toronto1 df from a dos prompt of the machine that you wish to schedule this from. At the filer console you'll get an rsh error similar to: toronto1> Thu Oct 18 07:34:26 EDT [rshd_0]: Permission denied to rsh request fro m gberry at 99.118.225.53 2) Using that info for an example go and edit your <filerroot>/etc/host.equiv file with wordpad and add a line that contains "99.118.225.53 gberry" and make sure you hit <enter> at the end of the line, save the file. Then try "rsh toronto1 df" again to test and it should work just fine. A .bat file to do this would simply contain the command(s) you wish to execute. You can also use the "-l <username>" option on the rsh command if that's handy. Just type rsh at a dos prompt and it'll give you the syntax. I hope this helps.

Ndmpcopy or vol copy (data migration)?
by Dawn Lovell 18 Oct '01

18 Oct '01

I know this very issue has been discussed previously, but I'm seeking some clarification. We have a 210 running 5.3.6R2 that we're replacing with an 820 running 6.1.1R1. The filers both have 100mb/full-duplex connections on the same subnet. Our initial plan was to vol copy the single 36GB volume on the 210 to a new volume on the 820. We've used vol copy to move roughly the same amount of data from a 210 to a 740 in the past, although both were running the same DOT version. After reading the archived discussion on the filesystem reversion necessary when migrating between 5.3.6R2 and 6.0.1R1, I opened a case with NetApp to ask about the time involved for reversion and if the filesystem would be upgraded after the vol copy completed. The support engineer pointed out that there are possible data safety issues with doing a vol copy from the older hardware/OS to the newer and strongly suggested avoiding vol copy and using ndmpcopy instead. I guess I'm just seeking some additional opinions, as vol copy has worked so well for us in the past. We can certainly use ndmpcopy with some variation of level0/incremental (or rsync), but I'm concerned the move will end up taking longer that way than if we just schedule several hours of downtime and vol copy once. I don't want to do something unsupported, but my impression (from the archived discussion) was that vol copy should work after the target filesystem was reverted. Is vol copy actually unsupported by NetApp in this scenario? Has anyone done this and had problems? Thanks very much for your time! Dawn Lovell dlovell(a)centurytel.net

RE: NetApp and EMC Comparisons
by Joe Luchtenberg 18 Oct '01

18 Oct '01

1. The article, while making some valid points about the industry in general with regards to FC SAN and TCP/IP NAS, misses a lot of significant points about Network Appliance. Furthermore, in making generalized statements about the NAS market (most platforms of which are tuned Win2K Advanced Server devices or some-flavor-of-Linux), these would mis-characterize filers if applied to them. When comparing NetApp filers to competing SANs the important comparisons to make are between WAFL and NTFS/xFS. For instance, when addressing the scalability requirements for large enterprises, The Clipper Group states, "[NAS] will likely require, over the long run, much more IT staff involvement than [SAN]," the argument being that it takes more resources to manage many small (their characterization) filers than fewer behemoth SANs. I think most on this list would refute that point for many reasons. 2. Without understanding the requirement you seek to address, it's hard to make pertinent comparisons between EMC's IP4700 and NetApp filers (I assume this is the comparison you're making, not Celerra vs NetApp). However, some general points to consider: - if you're doing anything other than home directories and general purpose file sharing, you should consider the level of application support for the two platforms (I believe you will find NetApp is more likely to have certified support on their filers, although in researching this I was surprised to find EMC had certified Oracle on IP4700; nonetheless, from my point of view EMC will want you to do anything other than home directories and file sharing on a Sym). - IP4700 RAID5 / NetApp RAID4 -- inherent dynamic RAID set expansion advantages to NetApp - IP4700 RAID set sizes are restricted to 5- or 10-disk multiples -- less user configurable - no competing offering to NetApp's SnapMirror from EMC for the IP4700 platform 3. Getting back to your specific question about admin... Generally speaking, EMC supports their own products. This support is surely world-class, but it also carries a world-class price tag. As an administrator you won't be adding storage capacity, loading patches or performing other typical tasks -- they will (unless you get and maintain expensive certification training). In today's bloody market (EMC lost over $1B last quarter) vendors are doing everything they can to move product. Getting demos should be easy from both (now that manufacturing has had time to catch up with the response to Sept 11 -- for a while all demos and stock from a number of h/w vendors were redirected to NYC and DC for disaster response). Get 'em both in your lab and try 'em out for yourself. Let us know what you find. Just my $.02.

Write permissions on CIFS share
by Ian F. Jarvis 18 Oct '01

18 Oct '01

NetApp gurus, I have a scenario where I am unable to gain write access to a CIFS share on our Filer for a local Filer account. I can map a drive, read and execute with no problems but cannot write to the share. Due to our security policy, our Windows NT boxes and Filer are in workgroup and not in a domain. The Filer is being used as a store of log data from servers and not for any 'user' data. PlainTextPasswords is enabled on the Windows NT machines. The user account in question has been added locally to the Filer and the share has a mixed security style. The share has 'everyone' access with full control. I have attempted to map the user account to pcuser and even root in usermap.cfg with no luck. I am able to write when mapping the drive as root. Although the user account shows up with the useradmin userlist command, it is not showing in /etc/passwd. I'm not sure if this is an issue or not. Hopefully there is something simple I am missing here. Data OnTap version: 6.0.1R3 Licenses: CIFS, NFS Thanks in advance!!
