RE: multi mode vif on two (or more) different switches
by Kimminau_Eric＠emc.com 22 Sep '05

You need to define a port on each switch as a trunk, span the VLAN(s) configured on each switch to be carried on the trunk(s) and then connect the two trunk ports via a cross over cable. This would be the same as trying to connect 2 hubs via a cross over cable (where a hub is only a single broadcast domain == a VLAN). -- ---------1---------2---------3---------4---------5---------6---------7 Eric Kimminau Email: Kimminau_Eric(a)emc.com Senior Corp.

multi mode vif on two (or more) different switches

Hello I tried to configure multimode vif's on two different HP ProCurve 3400cl-24G Switches (802.3ad able). I think i have to Cluster the switched, but how???

I think you can either use a Super Stack cable like with cisco switches or use a port on each switch as uplinks to make the switch pair part of the same Address Space / Segment etc... -----Original Message----- From: owner-toasters(a)mathworks.com [mailto:owner-toasters@mathworks.com] On Behalf Of Andreas Pulker Sent: 22 September 2005 16:25 To: toasters(a)mathworks.com Subject: multi mode vif on two (or more) different switches Hello I tried to configure multimode vif's on two different HP ProCurve 3400cl-24G Switches (802.3ad able).

RE: revert from Ontap 7.0 to 6.5.5P9
by Watanabe, Steve 22 Sep '05

22 Sep '05

In order to revert you'll have to boot 7.0 into normal Data ONTAP and then do "revert_to 6.5". The older version doesn't have any knowledge of the format of a newer version as the newer version didn't exist when the older version was developed. -Steve > -----Original Message----- > From: soeren.daehnrich(a)previewboard.com > [mailto:soeren.daehnrich@previewboard.com] > Sent: Thursday, September 22, 2005 7:05 AM > To: toasters(a)mathworks.com > Subject: revert from Ontap 7.0 to 6.5.5P9 > > > Hi, > > i have a Problem with a FAS270, the Ontap Version is 6.5.5P9, > but the Raidlabel is from Ontap 7.0. > > In which Mode (maintenance or other) can i use the command > "revert_to 6.5.5?"

Hi, i have a Problem with a FAS270, the Ontap Version is 6.5.5P9, but the Raidlabel is from Ontap 7.0. In which Mode (maintenance or other) can i use the command "revert_to 6.5.5?" I can't find the command in the Maintenance or the CFE Mode. The FAS270 is down and halted. Thank You Soeren Daehnrich PS:Sorry for my English.

RE: sybase
by Reinoud Reynders 22 Sep '05

Hi Frank, We are running our sybase DB's on netapp filers. Some figures: Sybase is running on a Sun 6800 with 14 CPU's and 14 GB of RAM. We are running two sybase servers on that hardware: * PeopleSoft HR: 139 GB data and 5 GB log (grow 18 MB/day) * Clinical Workstation: 545 GB data and 21 GB log (grow 250 MB/day). * +70 smaller DB's. We have +1000 concurrent users on the system. We use FC on a FAS960c for the data and FAS3020c for the logs. We have decide to split data and logs for very specific disaster recovery raisons. We want to do a load DB of one DB (standby) without performance impact on the other DB's (production). For the sybase, we work with raw devices and use Veritas for multi pathing. For mor info, You can always contact me.

Tuning SnapVault perf over WAN links
by John Stoffel 21 Sep '05

21 Sep '05

Hi all, We're running snapvaults across a WAN link and we'd like to make sure we're getting the best performance possible. Both for the initial transfer, and for the followup snapshots which sync up the systems. All the systems are running OnTap 7.0.1 currently. The source filers are F960s or F270s, so they've got plenty of oomph. The network is all Gigabit on the LAN side. We have a WAN setup with 45mbit/sec and 90mbit/sec links between various sites. But the latency is on the order of 90ms, which means that we want to have a TCP Window Size of around 2Mb to keep up streaming performance. I've been looking around, but I don't see anything which explicity addresses LFN (Large Fat Network) WAN links like this under snapvault, esp when there's a large latency in the loop. Does anyone have any pointers on what I can do to: 1) tune the TCP stack for better performance 2) monitor the Network settings (internally, I know I could use ethereal or some other external snoop tool). 3) get better stats out of snapvault for how the transfer is going, and how long it's going to take to Quiesce snapvaults. I've had some which are going on 300+ hours! 4) What other people are doing in this situation to monitor and control large numbers of snapvaults (we're doing per-qtree) across WAN links.

Incremental NDMP backup after volume migration.
by Roger Stansfield 20 Sep '05

20 Sep '05

I asked the following on the NOW Backup Community Forum but I haven't yet had any reply. Can anyone help, please? I have upgraded to ONTAP 7.0.1R1. I shall use ndmpcopy to copy vol2 to a new vol2flex- there's enough space. I shall remame vol2 to vol2trad and vol2flex to vol2. vol2 contains files accessed by CIFS. We run nightly ndmp incremental backups (Netbackup, Windows). 1. Will the backup after the volume renaming be as normal (because most file modification times are still prior to the last incremental) or will we get a backup of everything (because some archive status bit shows none of the files have been previously backed up)? 2. To migrate, I may, in the event, do a level 0 ndmpcopy on a live system followed by a level 1 ndmpcopy with the volume restricted. Does this make a difference? 3. Later, I shall handle vol1 which has files accessed by both NFS and CIFS. Will the situation be different on this volume? 4. If a "level 0" backup is going to be produced, is there some way of avoiding this or are there good reasons why we should want to get a full backup? -- > Roger Stansfield, > Rowett Research Institute, Bucksburn, Aberdeen, AB21 9SB, Scotland, U.K. > Telephone: 01224 716677.
