RE: Snapmirror initialization aborts consistently

Yes, sorry, VSM df, i can't do while the destination is restricted, i get this when i try to get df output hci2> vol status -b rcv_data rcv_data: volume is offline or is unavailable. hci2> vol online rcv_data vol online: Volume 'rcv_data' was left in an inconsistent state by an aborted vol copy or an aborted snapmirror initial (level 0) transfer. In order to bring it online, you must either destroy and re-create the volume, or complete an initial snapmirror transfer or vol copy.

accessing lun as a raw device using dm-multipathing from a rhel host
by Alexander Schalek 06 Nov '07

06 Nov '07

Hi! I have some troubles with a oracle rac installation on netapp fcp luns. We use rhel4 u5 with dm-multipathing with a 2.6 kernel Currently we have 4 partitioned and multipathed luns maped to the hosts(mpath0-3) but the rac installation exits with an error. I found the following lines in the fcp host utilities setup guide: Accessing LUNs using dm-multipath Accessing LUNs as a raw devices Overview Instead of creating a file system, you can access a LUN as a raw device. Be sure to use the /dev/mapper/ device created by dm-multipath to access the raw device. For the Linux 2.6 kernel used by RHEL 4, do not use the raw interface. Instead open the device using the open call with the O_DIRECT flag. ***** So I have to access the devices using the open call with the O_DIRECT flag!? Can anyone of you guys explain this sentence to me? How do I do that? Many thanks and best regards, Alexander

Symantec Antivirus Corporate Edition 10.1 and vscan on filer
by Richard Distrajo 04 Nov '07

04 Nov '07

Any help on registering the filer to the Symantec antivirus server. I tried to put the filer's hostname /ip address to the symantec antivirus center console but no success. Is this version of antivirus can register the CIFS only filer (ONTAP 7.2.2)? I'm getting error "no network provider accepted the given network path" every time I add the filer's IP address to the symantec antivirus console center...both sides can able to ping each other's hostname and user's permission is already been added as operator on the filer's side.... Thanks for your time on this.... Best regards, Richard Send instant messages to your online friends http://uk.messenger.yahoo.com

Re: R: VMWare CIFS driver
by Alan McLachlan 04 Nov '07

04 Nov '07

Hi Milazzo, You are absolutely correct, and beyond lower performance there's an issue of maintaining the CIFS connection in the case of cluster failover. However, if there's one thing that's true about I.T. it's that if something is _possible_, someone somewhere will have a set of circumstances (not necessarily technical, often financial or political), where that solution makes sense for them. 10 years ago it was a very hard sell to get people to access enterprise databases over any sort of file protocol, now Oracle themselves have vast deployments of Oracle over NFS. And Microsoft SQL Server over CIFS, while not so common, has been used for many years with both reasonable performance and high availability by many NetApp customers (although now we would recommend iSCSI with SnapDrive instead of course), and is a configuration that was originally supported by Microsoft only in the context of NetApp storage. It's very easy to say "that's a stupid idea", but eventually you learn that something that appears to make little sense on it's own can make more sense for a particular environment once all of the issues (technical and non-technical) are considered. There are serious scalability issues with using iSCSI or FCP for VMWare system images (leaving the data volumes aside as a seperate issue that is handled on it's own merits), and the NFS implementation is a very good solution for this apart from improving overall manageability of a large VMWare environment. While I would hestitate before using CIFS for this in any production environment, it may have value in creating a simple and scaleable dev/test solution for a client who then would still use iSCSI or FCP for their production vm images. regards, Alan. ----- Original Message ----- From: "Milazzo Giacomo" To: "M.

Windows SnapDrive Query
by Raj Patel 02 Nov '07

02 Nov '07

Simple question - We've just started to utilise some space on a second SAN head and for the life of me I can't remember what I needed to do on the SAN to allow our SnapDrive domain account to connect and create luns on the SAN. I've had a look 'useradmin user list' and 'useradmin domain list' but can't find anything obvious to match our domain 'sduser' account to a SAN account. When I use SnapDrive I get this in the event log - Error code : Access is denied. Verify that you have entered the correct domain and user name during SnapDrive installation and that this account has sufficient privileges to perform this operation. And this as a popup - SnapDrive error Error Description: User sduser does not have the capability to invoke API system-get-version I figure theres something really simple I'm missing or have taken for granted on our other SAN heads in terms of initial setup to use with SnapDrive. Cheers, Raj.

A-SIS questions
by Page, Jeremy 02 Nov '07

02 Nov '07

I have read some of the info on how A-SIS works but I have a couple of questions: 1) Assuming an average compression rate (say /home with random docs in it) how much of a performance hit does it impose 2) Does it change how much data is sent over the wire when you use SnapMirror/SnapVault? I.e. if I get 30% compression on a 1 gig snapshot do I send 1 gig or 700 mb to update my target? Oh, and for the folks who helped earlier, we are moving our Oracle and ESX systems to NetApp, the pSeries will be fibre connected, at least at first but the ESX stuff is all going on NFS. ~Jeremy This message (including any attachments) contains confidential and/or proprietary information intended only for the addressee.

RE: VMWare CIFS driver

Hi Peter, I can't disagree with anything you have said, particularly re. failover (see my post that followed). Incidentally though, it was an internal Network Appliance whitepaper that alerted me to the possibility of using CIFS for .vmdk files. See section 9.1.3 on page 58 of TR-3505i. I understand that being an internal paper I shouldn't be mentioning it here, and the published version of that paper on A-SIS eliminates the discussion of VMWare, I suspect because support issues haven't been nailed down yet. Still waiting on feedback from my contact in VMWare, will post when I hear something. There are other reasons beside statefulness of CIFS connections to prefer NFS (performance, etc.), but that's the main issue. I only mentioned it so as not to exclude it as a technical possibility, my followup posts were intended to stop anyone getting too excited about it at this stage. Also even if VMWare were to build it into the kernal, I'd still be pushing clients to pay for an NFS licence instead.
