Netapp and VMware... It's all so confusing!
by Timothy Hollingworth 01 Apr '10

01 Apr '10

So, say for example, I want to virtualize an Exchange server. Lets also say that I want to manage it via Snapdrive and SME. Lets also say, just for the heck of it, that I want both the new front-engined Acura NSX as well as the Porsche RC3. The cars aside, I would have to run iSCSI from within the VM, install and use Snapdrive from within the VM to provision LUNs, install Exchange and then use SME? It seems kind of silly to use iSCSI from within a VM if the ESX box were fiber attached to the Filer, just to be able to use Snapdrive and SME, no? I would love to be able to use the features of SD and SME within a completely virtual environment and am wondering what some real world implementations other VMware/Netapp customers are running. Do you run storage for the databases and logs in VMDK's and manage snapshots and backups from a VMware virtual machine perspective or do you manage them as iSCSI LUNs and use SD and SME? Or am I completely blind and missing something? Timothy L. Hollingworth Sr. Network Engineer, ePlus Technology Inc. 678.462.6698 (cell) AIM: HollingworthTim YIM: t_holling

autosupport stops functioning
by Leeds, Daniel 27 Feb '08

27 Feb '08

anyone else have this happen? suddenly one of our filers stops generating autosupport messages. both autosupport.enable and autosupport.support.enable are on. if i generate a test email with the autosupport.doit option nothing happens. not even a failed message, the console just sits there as if i never generated one. needless to say neither netapp or our email server gets anything from this filer and nothing hits the console about generating any autosupport emails.

HTTPS access only to FilerView
by Kevin Parker 29 Sep '07

29 Sep '07

Has anyone had any luck restricting FilerView to *only* https/SSL? Appears that enabling SSL allows https browsing, but does not restrict it to only https, as http is still allowed. Options httpd allow to restrict to certain workstations yes, but appears there's no way to configure it such that only https is allowed, and http browsing will return 404 or something like that. Any ideas? Thanks.

luns cannot be backup via backup exec
by John Sfetsoris 29 Sep '07

29 Sep '07

hello everybody we have several luns that cannot be backued up from veritas backup exec. These luns are mounted via cifs and had initally security style unix, that recently changed to ntfs (before starting backup proccess), therfore we cannot change the lun share from "none" to"read" in order to make them capable to be backed up (the command returns "read only file system"). Plz note that these luns are snapvault destination (no snapvault destination is running during the backup proccess). Has anyone any knowledge or a workaround in how to make the lun share "read" , and what else needs to be done , to be able to backup the luns thnks in advance John

RE: luns cannot be backup via backup exec

Just a thought, but the fact that its snapmirror destination its read only, there for backup program can't flip the archive attribute. Maybe that helps? **Sent using wireless handheld... please excuse any typo's or brevity** Kevin Parker - NWN Corporation kparker(a)nwnit.com (m) 919.830.5819 (o) 919.653.4489 -----Original Message----- From: "John Sfetsoris" <John(a)ivisinfo.gr> To: "toasters(a)mathworks.com" <toasters(a)mathworks.com> Sent: 9/28/2007 10:13 AM Subject: luns cannot be backup via backup exec hello everybody we have several luns that cannot be backued up from veritas backup exec.

NFS and VMware
by Page, Jeremy 28 Sep '07

28 Sep '07

Are any of the toaster folks using NFS for VMware in a production environment? We have about 150 VMs across 12 servers at the moment sitting on an IBM DS4500, but I just got my budget approved to buy a nice 3040 cluster. For ease of backup/restore/DR I really would like to use NFS instead of FCP/iSCSI but I don't know what the performance impact will be. Any comments/experiences?

I have done 7.0.4->7.2.2 on NFS/CIFS FAS270s with Sync SnapMirror (in May) and 7.0.4->7.2.3 on NFS FAS960c. The second one was completely seamless (I had service window so I did not bother myself with NDU). But the first NOT. We have faced two issues, both solved with NetApp support: - After upgrade CPU utilization was significantly higher (even after i2p conversion) than before. The problem applies to FASes with small amount of memory and was solved with some FlexShare settings. - The second one was serious: NTFS file permissions were displayed incorrectly from NFS clients although access rights were enforced properly. Customer's scripts stopped to work so NetApp suggested some setflag workaround. Although it was not in line with manuals and whitepapers NetApp called it feature. Now it is recorded as bug 245785. I have also done several other upgrades on different platforms and from different ONTAP releases including 6.4. No problems at all because all the filers were non-production ones ;-) It was expected behavior basing on Murphy's law ;-) Best regards, Jacek --- avast! Antivirus: Outbound message clean.

Assymetrical ipspace on cluster
by JacekN 27 Sep '07

27 Sep '07

IHAC who is using vfilers in non-default ipspaces on the cluster. Simplified configuration is like this: - node1: vfiler vf1 in ipspace ips1 - node2: ipspace defined but no vfiler uses it In both cases ipspaces includes single mode vif (I am not sure if it is significant in this problem). The configuration does not work during takeover of node1 by node2: there is no interface active for partner takeover (because no vfiler is defined in the ipspace ips1). I reproduced this problem on the simulator and found workaround: to create dummy vfiler on the node2 in the ipspace ips1. Is there any more elegant solution? Is it a bug or a feature?
