Thanks all. Great advice. So, my question is: if the second head can take over the personality of the failed head, why do I need to allocate any disks at all to the second head to begin with? Just a design thing? I'll probably do the even split thing.... and look into ordering additional NIC's. Can I have a "spare" that is available to either aggregate on either filer? This way I could do two RAID-DP's on each head with one common "spare" disk and rely on 4hr support to get me replacement disks quickly. Ray

HSM/ILM for Netapp
by Babar Haq 03 Jun '09

03 Jun '09

Hi all, IHAC who is searching for a product that can provide HSM/ILM function for massive NAS environment. This product can be either a hardware appliance, a software, or combination of both that can provide a total transparent solution for our user (i.e. regardless where is the physical data location, user can remain using it old logical path to access the same data) with tiered storage. So far I can only identify two products one hardware Acopia and the other one is software approach CommVault. Both have it pros and cons but the biggest challenges for both products are not able to manage snapshot and do not go down to qtree level. Thanks in advance.

This doesn't help when you do NDMP backups, does it? Also, do you *ever* trust version X.0 software? *grin* I'm not moving to CommVault 8.x or OnTap 7.3.x until they're more stable and widely tested. I need stability at work. John

ESX volume design question
by steve klise 02 Jun '09

02 Jun '09

What would you do? ESX 3.5 running all windows servers; FCP with all fiber drives We have an existing 6030 with 1 aggr, 1 large volume with ~5 LUNS 500GB a piece; running DOT 7.24. (upgrading soon, so no dedupe running yet). We have a new HA 6040 (PAM cards) =). The existing volume on the 6030 is still at 100 percent fractional reserve. We have SMVI running in our test environment, but not in prod yet. We wanted to snapmirror from the 6030 to the 6040 and visa versa. The 6040 is running 7.3.1.1 so I can only go from the 6030 to the 6040 for now. No vmware on the 6040 yet. Question: I have 3 shelves each for each head (6 300gb total for the 6040) and 1 big aggr on the 6030, 11.5TB agr 4.97used in the volume on the 6030. I was thinking of having the volumes for the 6040 @ 750GB and 1 LUN. I am averaging ~20 windows boxes. I figured when SMVI runs, it is only 1 snapmirror update vs running the job with allt he LUNS in 1 big aggr and multiple snapmirrors happening. I will make the fractional reserve set to 50% on the 6040 with thin provisioning at the LUN level, and dedupe. Pros: I think its more granular. Having to find a location for 6TB is a bit difficult Con: Not as much dedupe by having all VM's in 1 volume. Thoughts, experiences, gotchas.? -- View this message in context: http://www.nabble.com/ESX-volume-design-question-tp23821864p23821864.html Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

How are you using SnapDrive + iSCSI HBAs on a separated storage LAN ?
by Filip Sneppe 29 May '09

29 May '09

Hi, I am struggling to get the following setup to work properly: - A separated storage IP subnet, not routed to the LAN - A multihomed NetApp filer with an IP address on both the storage IP subnet and the LAN - A Windows 2003 server with a normal NIC on the LAN and an iSCSI HBA on the storage subnet. - The iSCSI HBA is a dual Qlogic HBA, but only one of them is connected, the other one is left unconfigured. I don't intend to use MPIO. - The setups I've worked on lately have all been boot-from-SAN setups, but I don't know if that's really relevant to the problem. Now, presenting LUNs and using them on the server (or even booting from them) has not been much of a problem, no issues there. The problem arises when I want to use SnapDrive for LUN management tasks such as snapshotting. From the docs I've read, what I gather is that I have to install the MS iSCSI initiator even when using iSCSI HBAs: https://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb8988 (this doc is not 100% clear to me: should I only select the iSCSI service during the installation, or also the MS iSCSI initiator itself ? What is the impact of selecting the MS iSCSI MPIO ?) I also make sure to change the initiator name on the HBA to the iSCSI initiator name used by the MS iSCSI initiator: https://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb21672 The end result is that my LUNs are accessible from the HBA. However, when opening the Computer Management MMC and going to the disks managed by SnapDrive, no disks are shown and the SnapDrive service is logging that filer IP address a.b.c.d is dead, as described in this article: https://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb30762 This article talks about fixing up domain credentials and name resolution, but from a network routing point of view, I can see where this error is coming from: the Windows server is not aware of the HBA connected to the storage segment and cannot reach it via its normal NIC, so it reports a dead filer IP address. Now, the quick fix would be to add the necessary routes to/from the storage IP network, but that would mean that this network is no longer fully isolated from the rest of the network, whcih I would very much like to avoid. What really drives me mad is that I have a setup at a customer site described as above that works perfectly fine (ie. SnapDrive shows the LUNs in the MMC and SMSQL can create snapshots & backups), yet I have another customer site where SnapDrive is unable to do anything because it cannot find the LUNs. Just today I was at a customer site with a setup as described above, where SnapDrive was able to work with the LUNs. They hadn't installed the host utilities, so I did the following: - Installed a MS hotfix required by the host utils - Installed the host utils - uninstalled a version of SMSQL and installed version 2.1.2 After a server reboot: boom, SnapDrive doesn't see ane LUNs any more, so no way to take any snapshots any more of these LUNs. So that's two out of three setups that are not working. I fiddled around a little with things: ie. installed the MS iSCSI MPIO, reinstallled the host utils (5.1) with MPIO support, etc. At one point, I had uninstalled the host utils & SMSQL, and then reinstalled the MS iSCSI initiator and SnapDrive, and I saw the LUNs again using MMC. I reboot one last time to make sure everything's fine, and ... bang ... no more visible LUNs from SnapDrive. So at this point I would like to know: - Has anyone had similar experiences ? - If you are using iSCSI HBAs on a separated storage network, what is your magic formula to get things working correctly ? Should I be able to get this thing to work without adding a route to the storage network ? Thanks in advance for your suggestions ! Best regards, Filip

SMVI "Operation timed out" during queice / vmware-level snapshot
by Ken Williams 20 May '09

20 May '09

Anyone seeing these types of issues? I have a FAS3070 cluster serving VMFS datastore over fiber channel to a 6 server cluster of ESX 3.5 latest SP. I seem to get a couple VMs (randomly) that are unable to perform the VMWare snapshot and cause the snapshot to fail. The problem seems to be hit or miss. Here's an excerpt from the log: 2009-05-19 19:18:47,556 INFO - FLOW-11012: Operation requested retry 2009-05-19 19:18:57,681 INFO - FLOW-11006: Starting operation in threadpool backup 2009-05-19 19:18:57,697 INFO - FLOW-11012: Operation requested retry 2009-05-19 19:19:07,822 INFO - FLOW-11006: Starting operation in threadpool backup 2009-05-19 19:19:07,837 WARN - VMware Task "CreateSnapshot_Task" for entity "snqfpapp01" failed with the following error: Operation timed out. 2009-05-19 19:19:07,837 ERROR - VM "snqfpapp01" will not be backed up since vmware snapshot create operation failed.

cifs share umask for a unix qtree
by Roy McMorran 20 May '09

20 May '09

I have a qtree that's shared among NFS and CIFS clients. The security style is Unix. If I set the umask to be 002, ie: filer> cifs shares -change myshare -umask 2 Then the files created in the share via CIFS still have the *execute bits set*: $ ls -al test.txt -rwxrwxr-x 1 user group 4 May 19 16:41 test.txt That's not what I want; none of these files should really be executable. I have read at least one thread in the list archives that suggest using a umask of 113, ie: filer> cifs shares -change myshare -umask 113 This seems sketchy, but I gave it a try. Well, it works for files, but also omits the execute bits from newly-created *directories*: $ ls -ald test* -rwxrwxr-x 1 user group 4 May 19 16:41 test.txt -rw-rw-r-- 1 user group 4 May 19 16:43 test2.txt drw-rw-r-- 2 user group 4096 May 19 16:48 test And directories don't work so well in that case! Am I missing something? Why should it not behave like the Unix umask command (with respect to directories)? OnTap 7.2.5 if it matters.

Re: Any luck with SnapMirror & ESX LUN's ?
by Raj Patel 18 May '09

18 May '09

I guess one key factor is that VIBE is free(ish) and unsupported(?) from what I've read but SMVI is a supported product at a commercial price-point. Anyone tried the VMWare Site Recovery Manager tool ? Is there a NetApp integration component in the works (my understanding is the product leverages SAN vendor API's to ensure consistant intersite replication of VM's) ?
