Hi I had previously checked on this and the second bullet is incorrect. LACP _is_ supported with 10GbE TOE cards. Share and enjoy!

The link used for inbound packets is decided upon by the device at the other end of the vif. I'm not an expert in this area but assume that TOE won't work because each TOE card wouldn't know what packets the other has processed in terms of inbound traffic.

Just for clarification if I have TOE turned on with 10G ethernet my units stop serving data with no cluster failover occurring. At least with 7.2.5.1 with TOE turned off the units appear to be stable previously they where unstable whether TOE was active or not.

Hi all... i dont know whether its the right forum to ask...but has anyone worked with DECRU FC-series integration with FAS6040... I have configured two FC-520 as a cluster...and added FAS6040 LUNs to the cluster storage... but when i try to present cryptainers to Solaris10 hosts...the host is unable to format the cryptainers (LUNs)...after partioning once i try to label the disk...it says...'CURRENT DISK IS UNNFORMATTED'.... Non-cryptainer LUNs on the same host work perfect.... Any ideas...suggessions...solutions...documentation reference???? thanx...

issues with 10G Ethernet.
by James Beal 29 Sep '08

29 Sep '08

I have a call open with netapp about this however I thought I would ask the list if anyone else has had similar issues. We have a cluster which is connected to our core via TOE-10G Ethernet (T320E-XFP). The problem we see is that the sometimes the netapp appears stop receiving any packets. I haven't done a packet trace while the problem is in effect as I have been a bit of a Muppet when I have noticed the problem as I had forgotten the rlm user name but I have made notes so next time it happens I will do a trace.. This has happened on both units in our cluster. We have replaced one of the 10gig cards and that has made no difference. Our networking people show no errors on the line cards. Power cycling the units brings the network card back. We have turned toe off on the cards and that appears not to make any difference to the reliability of the system. This has so far occurred 3 times which is really very poor. sysconfig -v 4 slot 4: Dual TOE-10G Ethernet Controller (T320E-XFP) Device Type: CT-31-1 Version Number: T3-SRAM1.1.0-BR1040-20-C0-FW4.6.0-DR03 Serial Number: PT3807035 e4a MAC Address: 00:07:43:05:13:ac (auto-10g_sr-fd-up) e4b MAC Address: 00:07:43:05:13:ad (auto-10g_sr-fd-cfg_down) ifconfig e4a e4a: flags=948043<UP,BROADCAST,RUNNING,MULTICAST,TCPCKSUM> mtu 1500 inet 172.17.66.26 netmask 0xffffff00 broadcast 172.17.66.255 partner inet 172.17.66.27 (not in use) ether 00:07:43:05:13:ac (auto-10g_sr-fd-up) flowcontrol full

AIX Power/VIOS Flex clones
by Ken Williams 25 Sep '08

25 Sep '08

Anyone doing flex clones on IBM power5/6 PowerVM platform? I've created a clone of a LUN and presented it to the VIOS servers. The system doesn't see the new device. From my understanding its because they share the same PVID. My question is how can I use flexclone technology without taking down the LPAR to make a clone. __________________________________________________________ Ken Williams Storage Administrator, Business Technology Operations Sacramento Municipal Utility District E-Mail: kwillia(a)smud.org Phone: (916) 732-6744 Cell: (916) 240-4213

How to re-fail a disk to trigger autosupport?
by Adam McDougall 23 Sep '08

23 Sep '08

We had a disk fail in a shelf on a filer with expired support, which created a case at the time but it was closed without replacement due to lack of support on the filer. However, as part of the support agreement on a new cluster, it was in a shelf that would be covered when attached to one of the new filers. Now that we have that shelf attached to the new filer, all I get is: Mon Sep 22 17:18:22 EDT [hostname: disk.init.failureBytes:error]: Disk 0b.23 failed due to failure byte setting. I tried replugging the disk and all I got was the same message in the log. After the message in the log, the filer acts like the disk isn't present as per commands below. How can I trick it intro triggering an autosupport so my bad disk gets replaced? Thanks. > disk fail 0b.23 disk fail: Disk 0b.23 not found > disk show 0b.23 DISK OWNER POOL SERIAL NUMBER ------------ ------------- ----- -------------

Test tape read speed
by A Darren Dunham 19 Sep '08

19 Sep '08

I'm trying to restore a file on a filer (via NetBackup) and the restore is *crawling* (a few KB/s on avg). One test I'd normally do would be to simply mount this tape up on the system and test that I could read it quickly. Is there any way to do this directly on the filer? I see 'dd', but I don't see how to read from the tape device. I don't think I can run a 'restore' because the data on the tape will be wrapped with NetBackup header information. I just want to test that the data can be read quickly. So actually interpreting the data isn't important at this point. Thanks. Background: Directly attached LTO3 drive. Backups are normally nice and speedy (50+ MB/s). ndmpd probe suggests that it's read 15GB of data in over 24 hours. *way* too slow. -- Darren

Identify traffic per IP address without using pktt
by Filip Sneppe 18 Sep '08

18 Sep '08

Hi, When using "sysstat" from the command line, it's very easy to get an idea of the network throughput that is currently being handled by the filer, and with commands like "vif stat" it's easy to get an idea on the interfaces that are transmitting or receiving this traffic. However, I am wondering if is it possible to get an idea on the client IP addresses that are generating most of the network traffic without having to resort to pktt every time, then copying over the capture file and analyzing it afterwards ? Are there any counters availble from a command that show how much traffic a particular IP address has sent/received ? I tried various commands (eg. netstat has a few interesting options) but couldn't find anything that solved my problem. At the moment, if I need to determine the hosts that are using most of the iSCSI or NFS bandwidth, I have to resort to pktt, and I am looking for a easier way to achieve what I want. Ideally, I'd like to get information on the protocols and ports involved too, but having IP addresses would already be very useful. Best regards, Filip

Inconsistent ndmpcopy performance on a 3020 cluster
by Nathan Patwardhan 17 Sep '08

17 Sep '08

Hello, We've got a 3020 cluster that's running OnTap 7.2.3; each node in the cluster is connected to DS14 and DS14MK2 shelves. We recently added some shelves (DS14 MK2) and as part of this maintenance we decided to migrate data off the existing traditional volumes to new flexible volumes since we're not interested in having traditional volumes anymore. For this purpose we used ndmpcopy -- to migrate data between shelves *local* to each node in the cluster, e.g.: filer> ndmpcopy -l 0 /vol/oldtradvol /vol/newflexvol Since we'd done this kind of maintenance on our other 3020s before, we'd expected throughput of ~18-20g/hr as this hardware is identical to filers we'd worked on in the past. Unfortunately results were totally inconsistent: node A performed as we'd expected and I was able to migrate 300g of data overnight. node B has consistently transferred 3-6g/hr. I'm not seeing any errors on node B and I've rechecked my cabling to make sure nothing is amiss. Why might I see such disparity in results on node A and node B? -- Nathan Patwardhan "But the album's biggest setback, other than the fact that its title sounds like a Neutrogena product, ..." -- review of Jewels' latest album

Matt, Yep, that's what we've found too, and I've logged a feature request. We planned to use a pagefile datastore which was snapmirrored less frequently and not snapshotted. However, SMVI can't really handle that (unless you kludge it with independent disks) but Vibe has no problem doing so. The problem for me is that Vibe is free and although less polished has the same, if not more functionality than SMVI.

Snaplock Enterprise
by Steffen Kammerer 15 Sep '08

Hi all, have anyone experienced snaplock enterprise? I have a snaplock enterprise aggregate in which I create volumes. As far as I know the volume will inherit the snaplock enterprise. The compliance clock is also set. -- The options of my testvol look like xxxxxx> vol options testvol nosnap=off, nosnapdir=off, minra=off, no_atime_update=on, nvfail=off, ignore_inconsistent=off, snapmirrored=off, create_ucode=off, convert_ucode=off, maxdirsize=20971, schedsnapname=ordinal, fs_size_fixed=off, snaplock_enterprise, guarantee=volume, svo_enable=off, svo_checksum=off, svo_allow_rman=off, svo_reject_errors=off, no_i2p=off, fractional_reserve=100, snaplock_default_period=min, snaplock_minimum_period=0d, snaplock_maximum_period=30y, extent=off, try_first=volume_grow snaplock options look like xxxxxx> options snaplock snaplock.autocommit_period none snaplock.compliance.write_verify off -- If I copy data in this volume (using cifs) and change the files to read only I can not change data any more. But the snaplock_minimum_period is set to 0 days. Now my final question: Is it not possible to create volumes within a snaplock enterprise aggregate without using snaplock enterprise?! Do you have any hints?! Regards, Steffen

Has anyone tried or tested pulling out a 3170 head from the new dual head chassis on the fly? Is there any magic steps to make sure things don't blow up when you do this?

You should power up the shelves first then the head. If these are supported devices, you should be able to get netapp tech support to help. ------Original Message------ From: Zeeshan Sender: owner-toasters(a)mathworks.com To: Toasters List Sent: Sep 10, 2008 12:46 AM Subject: Best Practices !!!
