migrating from 740
by Tim Longo 15 Sep '04

15 Sep '04

Greetings, I am currently running a F740 with about 1 terabyte of raw storage at about 50% utilization. I'm beginning to look into an replacemnt, perhaps an FAS250 or FAS270. At this point, I have a HVD SCSI connection going from my filer to a tape library for backups. The FAS250 etc, don't have a SCSI connectors, so I've been told I would need a converter from Ethernet to SCSI. Anyone using a converter for this purpose? How are people with the FAS250 backing up their systems? Any other … [View More]

I thought (as you mentioned) that setting it to 'high' would increase the reconstruct speed. I then used the filerview web interface to go in and change the raid reconstruct speed to 'high' and it actually set this value to 'low' - the web tool seems to set it to the inverse of what you'd expect. (setting 'low' on the web interface sets this option to 'high' etc.) So I was a little curious as to if the setting had a different meaning than the one you (and I) initially thought it meant. (eg: perhaps it's meaning impact on reconstruct speed rather than system performance, so 'low' means the least affect on reconstruct speed and therefore the most impact on system performance) I left it at 'low' since I figured the web interface probably knew the meaning of the option a little more than I did...

RE: OnTap 6.5.2/6.5.2P6/6.5.2R1 ?
by Hill, Aaron 13 Sep '04

13 Sep '04

My two cents; I have nothing good to say about 6.5 yet as it has caused us numerous panics and disconnects since it was released. It seems a new patch/debug for it is released very week. For the F840, there are some problems with CIFS and XP-SP2 that can prevent clients from connecting, so I would definitely upgrade to a version that addresses that issue. Which version? See if you can get a 6.4.x.... version to use until the 6.5.2R1 gets released. At this stage it looks like it is 1-2 weeks … [View More]away. Once 6.5.2R1 is released, I would move those Nearstores to it immediately, if only to avoid that Rapid Raid Recovery (or disk copy) bug (Bug#139525) that punished one of my systems using 6.5.2 last week. 6.5.2P6 was released to address it and other issues, however you can work around it specifically by temporarily disabling the raid.disk.copy.auto.enable option. Go R1 and then switch it back on. We are at 6.5.2. I am going to skip 6.5.2P6 due to some possible issues that may affect our environment and go directly to 6.5.2R1 when it becomes available. At the end of the day, you need to look at the bugs and compare them with your environment in order to determine if you are at risk. I hope this makes the decision a little easier. --Aaron -----Original Message----- From: Simon Ferrett [mailto:simon@musicmatch.com] Sent: Tuesday, 14 September 2004 4:59 AM To: toasters(a)mathworks.com Subject: OnTap 6.5.2/6.5.2P6/6.5.2R1 ? Hi Folks, Last week I updated my three nearstore units to 6.5.2 after experiencing a shelf-hang issue on two of them. That got me to thinking about updating another system (a F840 running 6.1R1 - it's been up forever, about 420 days) since it's running such an old version of OnTap and some of the clients here in the office are migrating to to XP-SP2. Anyhow - looking on the NOW site I noticed there are a few critical bugs in 6.5.2 which are supposed to be fixed in 6.5.2R1 - which doesn't exist yet. 6.5.2P6 does exist, however, so I was curious if I should wait until P6 becomes R1 before upgrading? I hate to rock the boat on a system which has been up and stable for a year and a half, but with XP-SP2 clients coming online I'm sure there's going to be some issues come up with the old 6.1 version its running. Also I was curious if I should also re-update the 6.5.2 systems I have to R1 when it comes out just to be sure that I'm not going to hit any of the known issues in 6.5.2 on them. Is anyone running 6.5.2P6 here on the list or have any comments about the actual critical-ness of those bugs in 6.5.2 which have been fixed in P6 (or R1 when it becomes available) - or know when 6.5.2R1 might hit the streets? The NOW site says 'this week' but I'm not sure when the document was authored... Just curious what the general consensus was on 6.5.2/6.5.2R1 etc. Cheers, Simon. --- This email message and any attachments are for the sole use of the intended recipient(s) and may contain confidential and privileged information.

RE: using NDMP for backups
by Alan Biren 13 Sep '04

13 Sep '04

Skip, BackupExec has a very limited implementation of NDMP. I believe for NetBackup it is an additional license. Dumps can be done in different levels 0-9 with zero being a full backup and 1-9 being incremental since the next lowest integer. ie: 0 level on Sunday, 1 on Monday, 2 on Tuesday, 3 on Thursday, 4 on Friday, 5 on Saturday. This would give you an incremental for the week with full dumps on Sundays. Differentials can be defined as well. As far as scheduling, that would require … [View More]some non-NetApp scheduler to perform. Windows Scheduler to kick off an rsh session. I have used many different backup platforms and the easiest to use I have found is BakBone's NetVault. I also like BakBone's Integration with NetApp. They are the developers of SnapVault and have plug-ins available to perform SnapMirror to Tape. I would have to agree with Tim. NDMP is a better utility to use for backing up to a robotic library. You get to take advantage of the media changer and can utilize multiple drives for backups. While with dump you can only use a single drive/tape system. A waste of your scalar 24.
