virtual tape
by Bui, Marcus 20 Sep '04

20 Sep '04

Hi Toasters, This is a bit off topic. I'm looking for a disk backup solution to complement our current tape backup environment. Currently, we are using Veritas DataCenter v4.5, on Solaris, and Quantum P6000/7000 library using SDLT. A lot of incremental backup are already going to the R200 but full and NDMP still goes to tape. Interested in something like a virtual tape solution that presents virtual tapes to Veritas and backup to the disk backend, R200. Also, if the virtual tape supports NDMP for the Filer backup that will be great. Appreciate any suggestions.

We use a device from Data Domain (the DD200 Restorer) which appears to NetBackup as a tape device and can be used with the Filers via NDMP. The appliance uses a lot of the same ideas as OnTap (apparently one of the first engineers at Data Domain was a former NetApp engineer) in how they perform data compression. As an example, even though the physical specs of the box are ~3TB storage, we're seeing data availability of up to 20-25TB (we can maintain about 6 weeks worth of full and incremental backups of our GroupWise and Filer on this appliance). Data Domain also has a new upgrade which will do multi-site mirroring of DD200 data (much like SnapMirror) If anyone is interested in more info on the box and what we're seeing out of it, let me know.

Why is that safer?

RE: Replacement disk problem
by Alan Biren 15 Sep '04

It depends on which version of ONTAP you are running. Before 6.5 you could destroy the volume from FilerView without first taking it offline. BE CAREFUL. There of course is the warning message. After the vol0(1) volume is destroyed, I would execute disk zero spares. -----Original Message----- From: jeff.mery(a)ni.com [mailto:jeff.mery@ni.com] Sent: Wednesday, September 15, 2004 1:34 PM To: Steve.Strange(a)netapp.com; johnkiniston(a)gmail.com; toasters(a)mathworks.com Subject: RE: Replacement disk problem Sender: owner-toasters(a)mathworks.com Precedence: bulk I agree 100%, but there is also a safety measure built in. "vol destroy" will only work against offline volumes. If you try to "vol destroy" the online volume, the command will puke and die with a message about the volume needing to be offline first. From what's below, Vol0(1), the foreign volume with disk 8a.13, will be offline. It can't be brought online because it's both incomplete and foreign. Vol0, the real and active root volume, will be online. This can easily be confirmed with a "vol status" command.

RE: OnTap 6.5.2/6.5.2P6/6.5.2R1 ?
by Simon Ferrett 15 Sep '04

15 Sep '04

Thanks - I generally run updates like this past the support folks to make sure I'm not digging a grave for myself before I jump on in - they recommended going to the latest 6.4 after updating the firmware to 4.3 before going to 6.5.2R1 - I probably need to wait until the WAFL updates are finished before doing the 6.4->6.5.2R1 update though. The nearstores are already on 6.5.2, so the update to 6.5.2R1 should be pretty boring... (at least I hope so) In the future I will probably keep a little more on top of keeping up with the GA releases as they come out to save pain when updating in the future (keep the version jumps to a minimum). It's just I also kind of subscribe to the "not-broke/dont-fix" philosophy as well. For example, I had a really old F880 in production which was running some ancient 6.0 version and had an uptime of some ridiculous uptime (~2 years) which I recently updated to 6.4.4R1 that I also needed to do in a couple of steps. Since it was a production box and not causing any issues I never updated it until finally a problem came up and support recommended (aka: insisted) I update it so they could better diagnose it.

Keep in mind that you'll need to install at least one intermediate release for the DOT 6.1R1 box, and possibly for your Nearstores also. I think you have to be on 6.4.2P6 or above to upgrade to 6.5. You'll want to confirm that though my mind is soft today.

RE: Fiber San

NDMP backup is the by far the best choice. You can ether use Veritas or IBM TSM. TSM has more advance features then NetBAckup, but it is more complicated to setup initially I would strongly encourage you consider new line of Cisco SAN switches (MDS). I think the it rather impressive .Among many advances, It will allow you to segregator backup in different fabric/VSAN.

All the HBAs on Windows server, connecting to another SAN, uses QLogic 24xx. The 3800 is use primarily for Filer backup since our QLogic switch was not certify with Netapp at the time. So far the QLogic, 3800, and Netbackup works great. You will need to the NDMP option with Netbackup to backup the Filer without using CIFS shares. NDMP will likely increase your backup performance.

The Brocade 3200 is a solid box and I have used Brocade for about 7 years with almost no real problems. However, I have started using the QLogic 5200 recently due to its REALLY lower price and have not had any problems with it either. But the QLogic isn't on the compatibility matrix. I have also used the CISCO 9216, which I like better than Brocade but it is also pricey. Keep in mind that in this case, you are not doing FCP so the compatibility matrix for FCP does not directly apply. For the Windows 2003 box, I have used Emulex, QLogic, LSI and JNI (now AMCC) Host Bus Adapters (Fibre Channel NICs) and I really prefer the QLogic 2340 (or 2342 for a dual port). It is the only card I have used that NEVER had a problem.
