Ok, one last questions: Snapshots
by Julius Talbot 29 Aug '01

29 Aug '01

Sorry for the newbie questions, one last question When I do a df, for instance /vol/vol0/ 127105232 748236 26356996 1% /vol/vol0/ /vol/vol0/.snapshot 31776304 4548 31771756 0% /vol/vol0/.snapsh ot Does vol0's capacity include the snapshot capacity? That is to say, vol0 is really 127105232? Or, is vol0 really that plus the reserved snapshot capacity, in this case, 127105232 + 31776304? Second I do understand from the documentation that if that snapshot exceeds the specified size, it will eat up the volumes capacity. In this case, both vol0 and snapshot would reflect the exceed capacity, right? -- _______________________________________________ FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup Talk More, Pay Less with Net2Phone Direct(R), up to 1500 minutes free! http://www.net2phone.com/cgi-bin/link.cgi?143

Oracle hot backups and snapshots
by John Hope-Bailie 29 Aug '01

29 Aug '01

Greetings, We are trying to utilise a NetApp filer's snapshot feature to enable rapid recovery in an Oracle DB environment. We are aware of the www.netapp.com/tech_library/3049TR document which covers the basics. The intention is to use the hot backup alternative to create several snapshots throughout the day to provide maximum coverage. Both Oracle 8 and 8i are in use. I have 2 questions :- 1) The TR defines a sequence in which all tablespaces are placed into hot backup mode. It has been suggested that this step might take an extended period of time. Our tests to date have been on relatively small data volumes and the "ALTER TABLESPACE <name> BEGIN BACKUP;" steps have been almost instantaneous. Is it likely that this step would end up taking longer (say tens of minutes) for large DBs ? 2) The system has been set up so that each "customer data set" is defined as a separate schema, many of which are contained within a single database. Each schema contains one or more data files, but these only contain data related to their own schema and not other schemas. The idea here is that if it was necessary to recover data related to one customer, it should be possible to do this without taking any other customer tablespaces offline. During testing we have found that recovering the entire snapshot (with all data files from all schemas) works fine. But when we have recovered only the single datafile related to one schema, we have run into problems. I feel we may be overlooking some basic issue here. Any advice would be welcome. regards, John Hope-Bailie Source Consulting, South Africa email: johnhb(a)sourceconsulting.co.za

RE: access filer from boot floppy [getting OT]
by Mumphrey, Robert N 29 Aug '01

29 Aug '01

We send our images directly to the filer. One problem we initially had was that you need to make sure that the NIC card speed and duplex on the PC is not set for Auto Detect. Set the Speed and Duplex manually in the protocol.ini on the floppy. Each NIC is different in how you need to set this, so you will need to find out what works for your NIC. Also, on the ghost command line, we needed to specify a different buffer size than the default. We use a buffer size of 8 and it seems to work fine. If we left it default, it was extremely slow.

RE: Ok, one last questions: Snapshots

The total space for vol0 does *not* include the SnapShot space. The real total space is the vol0 space PLUS the snapshot space. You will see this if you play with the SnapShot reserve space. Change the value and the values change. If your SnapShot reserve fills, it does start eating active filesystem space. The snaphost reserve line will then exceed 100%. The volume may not. If, for example, you had a 5% snap reserve, but your snapshots were chewing up 10% of the total volume space, then the snap reserve would be at 200%, but the vol0 space would still be at the capacity of the total blocks used, both active and snapshots which could very well be below 100% utilization. I hope this isn't too confusing. Let me know if you have further questions. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Julius Talbot [mailto:jstalbot@mail.com] > Sent: Wednesday, August 29, 2001 11:44 AM > To: toasters(a)mathworks.com > Subject: Ok, one last questions: Snapshots > > > Sorry for the newbie questions, one last question > > When I do a df, for instance > > /vol/vol0/ 127105232 748236 26356996 1% > /vol/vol0/ > /vol/vol0/.snapshot 31776304 4548 31771756 0% > /vol/vol0/.snapsh > ot > > Does vol0's capacity include the snapshot capacity?

Sample outputs? (Please help!)
by l l 29 Aug '01

29 Aug '01

Could some nice souls send me outputs from running "sysconfig; df; ifconfig -a"? If you're feeling very nice, "sysconfig -v;df;ifconfig -a;exportfs;cifs shares;vol status"? And if it has a partner, run the same commands against the partner? I'm trying to fix some perl scripts which keep breaking, so I can finish a customer implementation. Anything would help, but ideally im looking for __partner pairs, vifs and trunks__ and any weird config's you can think of. Feel free to obfuscate the files if you need, such as change IP addresses to another subnet... however, I won't use them for any purpose but testing. Thanks! And I owe you one! -- _______________________________________________ FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup Talk More, Pay Less with Net2Phone Direct(R), up to 1500 minutes free! http://www.net2phone.com/cgi-bin/link.cgi?143

RE: Clustering question.
by Rousseau, Deborah 28 Aug '01

28 Aug '01

Yes, the only other thing is the NIC card. You can add a hot standby NIC on each filer, or you can configure the cluster to share each existing NIC card in failover situations. But you don't need any other software. Ontap needs only to be licensed for clustering. The System Config Guide on the NOW site is a great little tool for finding out hardware particulars, part numbers and such: http://now.netapp.com/NOW/knowledge/docs/hardware/syscfg/ Best regards, Deborah Deborah Rousseau Network Appliance -----Original Message----- From: Kelly McQuarrie [mailto:kellym@sd.us.am.ericsson.se] Sent: Tuesday, August 28, 2001 1:44 PM To: Shaun Erickson Cc: toasters(a)mathworks.com Subject: Re: Clustering question. Hi Shaun: You need some extra hardware to do that clustering and a license for the clustering from netapp. The hardware you will need (and may already have you need to check) is second LRC's in every self and the cabling for it and a servernet card in each head and the cabling for that. I think that's about it but maybe somebody else can verify.
