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

Re: Other OPS?
by Mike 02 Oct '09

02 Oct '09

Metadata work, mostly - directory crawls, access checks, things like that (in CIFS). In NFS, ACCESS, READDIR, READDIR+ , stuff like that. I think you can use 'cifs top -s ops' to see the busiest clients hitting the system. If the ones at the top have very high ops, but not many reads/writes, those could be your guys. That said, it's all about latency. If it isn't driving latency higher, shouldn't be a concern. Those are different stats commands, though, can't remember right now...... --- On Fri, 6/5/09, Page, Jeremy <jeremy.page(a)gilbarco.com> wrote: > From: Page, Jeremy <jeremy.page(a)gilbarco.com> > Subject: Other OPS? > To: toasters(a)mathworks.com > Date: Friday, June 5, 2009, 3:10 PM > > > > > > > > > > > > > > > > What > causes other ops? > I understand that pretty much everything that hits the > filer requires something > but I am seeing what looks like a very high number of other > ops when I do a > stats show.

Re: Hanging NDMP backup sessions?
by John Stoffel 17 Jul '09

17 Jul '09

Patrick> There is a known bug regarding hanging NDMP sessions and this Patrick> ontap version. Upgrade to the P2 version and your issue Patrick> should be resolved Thanks for the info, though in my case I'm not sure if that's completely the issue, since it looks like the NDMP session(s) tend to go away properly, but the backup sessions don't terminate properly, which leads to NDMP failures when they can't allocate new backup sessions. In any case, I'll login to NOW and see what I can find in terms of the changes between 7.2.6.1 and 7.2.6.1P2 that relate to NDMP. Thanks! John

Hanging NDMP backup sessions?
by John Stoffel 17 Jul '09

17 Jul '09

Hi all, Is anyone else seeing hanging backup sessions under 7.2.6.1 when doing NDMP backups to a directly attached FC LTO4 tape drives, using CommVault 7.0.0 Update 76 Version #### software? For example: > ndmpd status ndmpd ON. Session: 79 Active version: 4 Operating on behalf of primary host. tape device: not open mover state: Idle data state: Idle data operation: None > backup status ID State Type Device Start Date Level Path -- ----------- ---- ------ ------------ ----- --------------- 0 RESERVED NDMP 1 RESERVED NDMP 2 RESERVED NDMP 3 RESERVED NDMP 4 RESERVED NDMP 5 RESERVED NDMP 6 RESERVED NDMP 7 RESERVED NDMP 8 RESERVED NDMP 9 RESERVED NDMP 10 RESERVED NDMP 11 RESERVED NDMP 12 RESERVED NDMP 13 RESERVED NDMP 14 RESERVED NDMP 15 RESERVED NDMP 16 RESERVED NDMP 17 RESERVED NDMP 18 RESERVED NDMP 19 RESERVED NDMP 20 RESERVED NDMP 21 RESERVED NDMP 22 RESERVED NDMP 23 RESERVED NDMP 24 RESERVED NDMP 25 RESERVED NDMP 26 RESERVED NDMP 27 RESERVED NDMP Now I know I can just do: > backup terminate # to cleanup these sessions, but I'm wondering why I'm seeing them in the first place, esp since my other sites running the same software and OSes aren't seing these issues, or at least not to as great a degree. It could be that I've mis-configured CommVault somehow...

Mounting VMware Volume Snapshot on Windows Host
by Skip Norman 10 Jul '09

10 Jul '09

I have a windows 2003 server with Snapdrive 4.2.1 and I was wondering how I can mount a snapshot of a volume that holds vmware luns. Is this possible? I was told that this is feasible with VCB framework installed; however, I currently receive an error: "unable to connect disk. Failure in connecting to the virtual disk. Error: A timeout of 600 secs elapsed while waiting for the volume arrival notification from the operating system". I have verified that I can mount exchange volume snapshots for SMBR recovery on this machine. Also, what are others here doing for image level backups of their VM's? Are there better/cheaper alternatives to VCB and SMVI? How is SMVI working out for those of you out there using it? Thanks.

Strange data loss on a Netapp NFS volume
by Straub Ciaran 07 Jul '09

07 Jul '09

Hi Tosters, Has any one ever encountered a strange data loss on a Netapp NFS volume? Last Sunday there was an incident Production of my customer was down as 2 Oracle database was gone form the volume. The Netapp was not serving the database to the application server. There should never be a Full volume or Full aggr, but things happen we all know Mr. Murphy law. The volume did reach maximum size at some point, and there was a hanging snapmirror.

Snapdrive problem
by David.Ashton＠rullion.co.uk 06 Jul '09

06 Jul '09

Hi Toasters Last week we attempted to extend a disk - a lun mounted in windows 2003 server using snapdrive (ver 6.0.1) - something we do fairly often. The event viewer on the server reported: Failed to expand the LUN by 51200 MB. Failure in expanding NTFS file system on the disk. LUN Name = bondv8_database.lun Storage Path = /vol/vol_bondv8/ Protocol Type = LUN Storage System Name = RULWAFAS01 Error code : The parameter is incorrect. However, the filer actually did expand the lun, and from the filer everything looked kosher. Windows however, did not reflect the change. We disconnected/reconnected etc and it wouldn't change. Netapp told us to either a) rewrite the MBR on the disk manually using a windows support tool (beyond our expertise and a bit scary) or b) copy all the data off, destroy the volume, recreate, and copy back. We did (b) and the copying of the data to a new volume took 7 hours, and once we destroyed/recreated a new volume, the copy back took 2 hours. This was all over the Fibre channel, and the speed difference I cant account for, I can expand the new lun/volume using snapdrive with no problems now, but have to admit my confidence in snapdrive is shaken. It's taken all weekend to sort this out (following an aborted copy on saturday) and am worried that such a fundamental facility of the SAN is being compromised by the Snapdrive software. Has anyone got any ideas as to why windows would do this? Its not happened before, and its a stable server, all upto date. Ontap is 7.2.5.1, filers, FC switches, drivers etc were updated late last year and we've been very stable. thanks Dave Ashton ********************************************************************** The information contained in this e-mail and any attachments are intended for the named recipient(s) only.

Hi Toasters, Need help regarding Snapdrive AIX, it fails everytime I create disk using Snapdrive for AIX. But If I am doing the lun create and mapping the lun manually to the AIX host it works fine. The AIX host can dicover and use the LUN I have created manually from the storage. Here is the error I am getting; gsb-t-mgt-01 # snapdrive storage create -lun 10.1.100.80:/vol/voltest/lun2 -lunsize 10g LUN 10.1.100.80:/vol/voltest/lun2 ... created mapping new lun(s) ... done discovering new lun(s) ... *failed* Cleaning up ... - LUN 10.1.100.80:/vol/voltest/lun2 ... deleted 0001-476 Admin error: Unable to discover the device associated with 10.1.100.80:/vol/voltest/lun2. If multipathing in use, there may be a possible multipathing configuration error. Please verify the configuration and then retry. default-transport is fcpmultipathing-type is nativempio Thanks in advance.... New Email names for you!
