Running OnTap SIM 7.3 on ESX VM
by Robert Borowicz 10 Oct '08

10 Oct '08

He all, I'm working for a start-up now who is trying to develop against the OnTap SNMP agent and API to do Systems Mgmt with the appliance we make. I've suggested using the SIM for OnTap 7.3 and have stood it up on a ESX VM imaged with CenOS 5.2. I can install the OnTAP SIM just fine with all the defaults using dir /sim, 3 disks, and using eth0 on the VM image of CenOS. Our lab at work uses 192.168.10.1 for a Def Gate and the host VM is using 192.168.9.110 and I can ping the Def Gate from CenOS just fine. But when I fire up the SIM (letting it DHCP an addr) I can't ping the Def Gate from the SIM. So I asked the ESX admin at work to create another interface on my VM CenOS environ. He gave it a static, (192.168.9.109) and I applied it to eth1 as it were. I STILL can't ping the Def Gate via the SIM. I CAN ping the IP I stood up for the SIM (.109) from other boxes in the lab but just not ANYTHING from inside the SIM on the VM. Anybody try to use a VM to run the SIM in and see similar experiences ? I stood up the same 7.3 SIM at home on a Generic Athlon 3200+ running CenOS 5.2 and it's FINE. That box only has one NIC and the OnTap 7.3 SIM piggy backs onto eth0 just fine creating NS0 and booting up fine. Suggestions welcomed. I've asked the lab manager for my own bare metal to run the SIM on in meantime.... TIA -Rob

Synchronous SnapMirror destinations + NDMP moves
by Nick Silkey 07 Oct '08

07 Oct '08

(NB: Resent from $oldjob. Newly-subscribed identity is having issues posting.) Toasters -- Anyone out there NDMP moving data from synchronous SnapMirror destinations successfully? We have a FAS3020C cluster at 7.2.4 and are moving forward on each head synchronously SnapMirroring via GigE to a remote FAS3020, also at 7.2.4. Ultimately we want to cut backups via NDMP to TSM over FCP from the SnapMirror destinations on secondary storage. There are some concerns which were raised by our SE about SnapMirror and NDMP stepping on one another, <http://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb44293> being one example. Looking to hear from those in the trenches on the above. Thanks. -- Nick

Aggregate snapshot on metrocluster
by Nicholas Bernstein 07 Oct '08

07 Oct '08

Does anyone know if the aggr snapshot can be turned off on a metrocluster? It looks like it creates a separate aggr snapshot that metro uses, and the schedule could be disabled, or paired down for space reclamation. -Nick -- Nicholas Bernstein Technologist, Consultant, Instructor http://nicholasbernstein.com

Re: Mail Delivery Failure

I¹ve noticed a couple of these bounces over the last week or so. Would it be possible to adjust the majordomo settings to have the list rewrite the sender to bounce messages go to a single /dev/null address? -Nick On 10/7/08 6:16 AM, "Mail Manager" <-----------> wrote: > Please do not reply to this note. > > The mail address <------------> is not valid. > > Your message with subject "Re: AIX over FC speed issues" was not delivered. > > Following are the original recipient(s). > > <---------------> > > -- Nicholas Bernstein Technologist, Consultant, Instructor http://nicholasbernstein.com

AIX over FC speed issues
by Page, Jeremy 07 Oct '08

07 Oct '08

We've replaced our DS4500 and EMC systems with an IBM rebranded 3070 cluster. For the most part I'm very pleased with the performance but for a specific application the new system is about 15% slower then the old DS4500 was, even though it's got more spindles at the same speed then originally. Old system (DS4500) (15k FC) 8 disks in a RAID 5 array 10 in a RAID 10 array 2 more mirrored New system (3070A) (15k FC) < This box is idling, the only stuff on it is this application (most stuff is on the other controller since I knew this app was a pain) 3 12 disk RAID groups in a single aggr (DP) Should be 20 versus 30 spindles. I understand that there may be a slight impact from DP versus RAID0/10 for parity calculations, but I expected it to be more then absorbed by the 16x size cache on the Netapp, the extra spindles and the NVRAM for writes. So any suggestions on how to speed this up would be useful. I'm going to have the AIX guy re-run his tests tonight while I have statit running to capture how the disks are impacted but I think possibly the bottleneck is elsewhere.

DECRU FTP ACCESS BUG?
by Milazzo Giacomo 06 Oct '08

06 Oct '08

Hi all A customer of mine asked me to set up ftp access on his E-Series cluster already acting as NFS NAS. OS is 3.1.1.1 I've followed instructions and it seems to work but there's a strange thing and something not clear. Once created the volume, exported, created virtual share, added the cryptainer I've enabled the ftp this way: >vip set -ftp-access on vnetapp1 In the guy I've created a user on the share called ftplogger with password and then I've set up his home directory this way >user home set ftplogger@app_domain rmrcrsdec-01:/vol/ciscolog (the domain has internal users only, no NIS or other external sources) Last I've enabled two hosts for test purposes, the first enabling both read and write and the other one only read (using the IP access functionality) What I've noted is that I can log on Decru using any username and password!!! My rights depend only from the IP. So that I can open a r/w ftp connection from the enabled IP address also using johndoe as user and any password!!! (I got this because once I was sure to wrong to input the password and I expected some 'access denied'...instead I log in!) FTP home dir seems to work fine, once logged user is pointed in the right share and if he tried to change he got access denied but if I perform the command: >user home list I can always read root@app_domain as user using rmrcrsdec-01:/vol/ciscolog and not the ftplogger user created.

san thin provisioning best practices doc
by Nicholas Bernstein 02 Oct '08

02 Oct '08

I'm looking for a good best practices doc I can point students to as a takeaway on using a fractional reserve with luns. Could anyone point me to a good doc? I looked on the now site and the best thing I came across was tr3483, but that just talks about how the process works as opposed to taking about best practices. Thanks, Nick -- Nicholas Bernstein Technologist, Consultant, Instructor http://nicholasbernstein.com

Operations Manager Options on FAS devices
by Jimmy Corncrake 02 Oct '08

02 Oct '08

Greetings all, Though FilerView we can set a number of Operations Manager options under the 'Operations Manager[image: Right]Access' tabs. These options include, *Operations Manager Links: **DataFabric Manager server:* *DataFabric Manager Protocol:* *DataFabric Manager Port:* ** I would like to set these options on the CLI but after looking and looking I can not find which command \option etc contains these. Anyone know? Perhaps it something I need to push from Operations Manager but this would surprise me somewhat. rgds, Jimmy
