restore_symboltable
by Tom "Mad Dog" Yergeau 01 Aug '01

Has anyone ever seen a file called restore_symboltable pop into a directory after an NDMP restore? I'm running 6.1R1 and doing an alternate location restore on the same filer. The file is always 2.20 GB in size. Thanks, Tom

RE: Power usage.

http://www.netapp.com/ftp/f700_series_specs.pdf indicates the F740 head unit consumes max 4 amps @ 90 VAC. (So I'd guess thats 3 A @ 120 VAC). If ou are using FC7 shelves (old, 9GB drive shelf), it draws 3 A @ 110 VAC. An FC8 shelf (18 GB drive shelf) draws 4 A @ 110 VAC. To find out the draw for the FC9 shelf, you have to go to http://www.netapp.com/ftp/f800_specs.pdf which indicates an FC9 shelf draws 5.5 A @ 110 VAC. Since NetApp doesn't update these data sheets for new shelves (hint hint, the FC9 shelf should be on the F740 data sheet, and the new DS14 shelf should be on both data sheets), I have no idea what the new 14 drive shelf draws. You can always call them, 1-888-4-NETAPP. At a colo you'd want to make sure you they provide two independent circuits on separate UPS units to power your filer, so that if a circuit breaker trips or a UPS dies, the filer stays up.

~9amps. 5amps for the F740 and 4amps for each disk shelf. -----Original Message----- From: Jordan Share [mailto:iso9@phantasticant.com] Sent: Wednesday, August 01, 2001 1:56 PM To: 'Toasters(a)Mathworks.Com' Subject: Power usage.

The question is if you are going to be installing just the filer and shelves or if you are going to be installing them contained in a NetApp Hardware System Cabinet. If it is in the cabinet Power: 16A, 208V AC, 60HZ Power Connector: NEMA L6-20 (times 2..dual plugs on the power distribution unit) For the Filer and the FCshelves f700 series filers: 90v to 250v AC single phase Fibre Channel shelves: 92V to 132V AC single phase or 187V to 264V single phase Minimum Current per AC input f700 series filers 4.1A at 90V to 120V AC FC7 3A at 92V to 120V AC FC8 4A at 100V to 120V AC FC9 4A at 100V AC I hope this helps.

RE: F760 cluster write performance
by Art Hebert 01 Aug '01

01 Aug '01

We ran into the same problem on 100mb, copying a 100mb file to the netapp took 23 seconds. We moved the 100mb nic off of the 32bit bus onto the 64 bit bus and the time to copy the file dropped to 11.5 seconds. This is unsupported but it works. What slot is your gig nic in? art hebert -----Original Message----- From: Allen Belletti [mailto:abelletti@dmotorworks.com] Sent: Tuesday, July 31, 2001 4:39 PM To: toasters(a)mathworks.com Subject: F760 cluster write performance Hello, We've been running a pair of clustered F760's since about February. Among other things, we are using them for Oracle database storage, with the hosts being Suns running Solaris 7 or 8. The interconnect is via gigabit Ethernet through a Cisco 3508 switch. We're doing NFS service only -- no CIFS. The volumes in question are between 60 and 80% full, and consist of between ten and 14 drives, either 18G or 36G depending on the volume. OS version is 6.1R1. NFS mounts are using UDP, version 3, rsize=32768, wsize=32768 (though Netapp has suggested reducing this to 8k). Recently, we have been running up against the limit of the F760's write performance, or so it seems. At best, a single (GigE connected) host is able to do 7-8MB/s of sustained sequential write traffic. These same hosts are able to read at greater than 30 MB/sec and sometimes as high as 50 MB/sec if the data is all in cache on the Netapp. What I'd really like to know is what kind of sustained write rates other folks are seeing in configurations similar to this one. At the very least, if you have any kind of F760 cluster, even without gigabit Ethernet, are you able to do more than 7-8MB sustained write? Also, when the writes are occurring, the filer CPU load is generally very high, anywhere from 80 to 100%. Disk utilitization is more reasonable, around 50% if the filer is not otherwise busy. My first thought (and Netapp's as well) would be that this is some kind of network problem, perhaps relating to GigE flow control. However, if this were the case I would expect the Filer CPU load to be lower. If anyone has seen (or fixed!) anything like this, I would appreciate any suggestions or advice.

Veritas b/u not clearing archive bit on NetApp volume
by Adrian Phillips 31 Jul '01

31 Jul '01

Hello List; We have an F760 running CIFS, with ONTAP 6.0.1R3. "C:" is mapped to vol0, and "D:" to vol1. We use Veritas BackupExec 8.5 over the network to connect to and back up the data/shares on these NTFS volumes. What is very odd (and I nor Netapp can seem to figure out thus far) is that the archive bit for files on C: do not get reset after full or incremental backups. Meanwhile, through the same backup jobs, the archive bit on files on drive D: DOES get properly cleared after being backed up. Because the archive bit is not being cleared on C:, our incremental backups are very large, and running well into the work day. I can't seem to find any differences in the volumes, other than vol0/C: is the root volume and uses 9GB drives, compared to vol1/D:'s 36GB drives. Regards, -Adrian

RE: snapmirror volume sizes

While this is true, it is a block for block copy which is why you still have to have at least the same # of blocks on the destination as you have on the source. -- Adam Fox NetApp Professional Services, NC adamfox(a)netapp.com > -----Original Message----- > From: Mike Federwisch [mailto:mikef@netapp.com] > Sent: Monday, July 30, 2001 7:38 PM > To: Jeffrey Krueger > Cc: Knight, Jason; 'Kelly McQuarrie'; toasters(a)mathworks.com > Subject: Re: snapmirror volume sizes > > > Actually, volcopy and snapmirror only transfer the used blocks. > Unused blocks are not transferred.

RE: snapmirror volume sizes
by Knight, Jason 31 Jul '01

Kelly, You are correct. Same size volumes. NDMPCOPY is a way to achieve the goal, it is a utility available on NOW and it basically does a backup of one filer and restore to another (or the same filer) concurrently. Jason Knight -----Original Message----- From: Kelly McQuarrie [mailto:kellym@sd.us.am.ericsson.se] Sent: Monday, July 30, 2001 3:32 PM To: toasters(a)mathworks.com Subject: snapmirror volume sizes Hello all: I think I know that answer to this one but I figured I would put it out here just to make sure I'm right. I wanted to use snapmirror to migrate a volume to a different filer. This volume is 225Gigs but it only has 68Gigs of data on it. If I'm to use snapmirror to do this then I need to migrate it to a 225Gig volume correct? I wanted to shrink the volume while I was at it so I'm thinking I'm going to have to do it another way. Has anybody had experience with this? Thx Kelly McQuarrie Unix System Administrator Ericsson CDMA Systems
