RE: Oracle on CIFS?
by Borders, Rich 26 Feb '04

26 Feb '04

Don't get me wrong. ISCSI is great, and I have have outstanding success with it. I will say that ISCSI is a protocol like CIFS so the Application may need a dependency on it should you have spanning tree on your Switch ( ~30 second network negotiation prior to port activation. If you are not needing it, then portfast enable off that option and then the port will be online asap. As for the ISCSI driver, as long as the NIC is online quickly, we rarely see any issues with the Oracle services in the same light as you mention the CIFS. Good luck with it, and you can ask more specifics off list if you like.

I think iSCSI has the specific following advantage : as the lun on the Filer is saw like a local drive, the Oracle service can start to work with earlier in the boot process of the Windows machine Oracle doesn't have to wait for the network and mapped drive to be up to work with these data this way you can move more Oracle data on the Filer (except the registry entry, all Oracle files can be migrated there - binaries, conf, redo log, datafiles etc...). This way, the Desaster Recovery procedure becomes much simplier. I am not sure 100% so tell me if I am wrong. Borders, Rich wrote: Keep in mind the space limitations of LUN's.

It can be drastic at the protocol, but the Filer needs to be ready for the performance internals. It can be a LOT of net traffic when you actually open up the GigE's for top performance.

NFS Security after upgrading to Ontap 6.5
by "Allendörfer, Carsten" 25 Feb '04

25 Feb '04

Hello, If you plan to upgrade to 6.5 make sure you check your /etc/exports file after rebooting with 6.5 for the first time. I just upgraded an 840 and an 880 and on both machines the exports file has been rewritten giving everyone read-only access. Running 6.4.2: /vol/vol10 -access=donald.zdv.uni-mainz.de:unixadm.zdv.uni-mainz.de:dschinny.zdv.uni-mainz.de,root=donald.zdv.uni-mainz.de:unixadm.zdv.uni-mainz.de /vol/vol11 -access=donald.zdv.uni-mainz.de:unixadm.zdv.uni-mainz.de:dschinny.zdv.uni-mainz.de,root=donald.zdv.uni-mainz.de:unixadm.zdv.uni-mainz.de ...

Cluster failover question
by Geoff Hardin 25 Feb '04

25 Feb '04

We've always had cluster failover on our filers for those times when something goes wrong on one filer and the other filer can serve the data. Realistically speaking, that rarely happens because the filers are stable. However, as time passes and the filers grow older, the develop more and more "personality." For example, we have a pair of F760s that are our problem children. As much as we'd like to pawn them off to another group, put them out to pasture, or replace them outright, that does not appear to be happening in the near future. Unfortunately, one of them has now developed a problem with a memory DIMM on the motherboard. In the past, we've had the luxury of being able to shut down the clustered pair of filers, but in our price conscious environment, people are asking what is the point of clustering if we can't do maintenance and keep the data available. So, my question is this: is it possible to work on a filer head while serving the data up from the cluster partner? My concern is that you are upsetting the FC-AL integrity because we'll have to unplug the FC-AL cables from the adapters on the head when we pull the motherboard tray out. Then, since the recommended course of action is to run diagnostics after reseating and/or replacing the DIMMs, could we run a small set of the diagnostics before plugging in the FC-AL cables? Maybe we could / should use the FC-AL reset function from the diagnostics menu to get the loops back to normal? Maybe we've just been too cautious with our data, but I'd like to hear from other toasters if this is possible, advisable, and safe before putting our data at risk. Thanks, Geoff -- Geoff Hardin geoff.hardin(a)dalsemi.com Put on your seatbelt. I wanna try something.

MX records
by Jerry 25 Feb '04

25 Feb '04

It appears the netapp configuration for a mail server doesn't lookup MX records (which I guess is used for autosupport). I have two MX records for my mail relay but no A record (by design). Have two A records is not desirable because MTA's will be confused and end up deferring mail for a little bit. I believe with two MX records, they try one then the other. With A records, they only get one back originally, try, defer, then continue to fail that piece of mail until it's re-queued later and happens to hit the other A record. Since dual A records are round robin, there is no real way of assuring it doesn't get the same A record back when it decides to look it up again (and maybe it even caches it for some time, not sure). Has anyone else experienced this problem? __________________________________ Do you Yahoo!? Yahoo! Finance: Get your refund fast by filing online. http://taxes.yahoo.com/filing.html
