You are using back slashes: rdfile \etc\messages You need to use forward slashes: rdfile /etc/messages

Interesting. Is the share mapped with Netbios or FQDN? I wonder if this is related to name resolution. Try with FQDN and with IP, see if it makes a difference how you are mapping the share. Also: - which OnTap version are you using? - Do you have SMB2 enabled?

If this data is only accessed over NTFS then I would be using NTFS security style on the volume/qtree rather than unix. Pure speculation here but some things to check if you are out of ideas: I would check the DNS setup is healthy and there are not timeout's to the DNS servers or DC's. Make sure you are hitting local servers if this is a large enterprise and make sure the DC you are contacting has received any replicated amendments to the group before you test. If the controllers IP's are not in a range defined in a local AD site they may be hitting DC's anywhere in the domain and timing out authentication checks. After you change the permissions have you tried log off/log on of the user account to see if you get immediate rights update? If you add a local user with Full Control and access the share with that do you get immediate permission update?

Great, if you remember can you post back once this gets updated or a firm date is in place. In the interim we have got around this issue by adding an entry in the /etc/hosts file for the short name of the source controller and the replication interface ip of that controller. Snapmirror updates still seem to work through System Manager and a netstat shows the traffic flowing over replication interfaces now. Not ideal having hosts file entries so still keen to see interface selection added as a feature to System Manager. Thanks Dominic

Hi Karthik, Are there any plans to support this in the future? I have another customer who also needs access to this feature. Thanks Dominic

You can list all unowned disks with disk show -n Do you mean which controller owned this disk before it was failed? You could look at the /etc/messages file or OnCommand (Ops manager) for disk failure related messages.

Hi Henry, It depends what you mean by installation check list. These are good starting points. http://now.netapp.com/NOW/knowledge/docs/ontap/rel802/pdfs/ontap/setup.pdf http://now.netapp.com/NOW/knowledge/docs/ontap/rel802/pdfs/V-Series/install.pdf The pdf in the first link has a section called "Configuration information you need to gather" which is a bit like an install check list.

Hi Adam, I can find plenty of statements that there should be only one transition from SAS to SATA in a stack but I can't find anything to tell me why that is. If this is not required why is it recommended? Thanks Dominic

Syslog file is at /etc/syslog.conf (cifs share will be \\filername\etc$\syslog.conf) Have a look at this KB, explains how to setup syslog. https://kb.netapp.com/support/index?page=content&id=1010374 or do you mean the messages file? You might want to have a look at /etc/messages if you are after a general record of what the filer has been up to recently.

Appears to be caused by this option on the vfiler in question: nfs.export.auto-update off now changed to: nfs.export.auto-update on Restores and mounts are now working. The initial setup was done by someone else so will go through and check everything.

I've been having problems during testing of single file restore, I keep getting this error (screenshot attached) "Mounting the backup failed. Reason: Error mounting". VSC error mounting backup - "Unmarshalling Error: prefix xsd is not bound to a namespace datastore" I've scaled back to simply trying to mount the backup using right click and select mount and receive the same error message. This environment is NFS datastores, vCenter 4.1.0, DOT 7.3.4P4, VSC 2.0.1 It's probably something simple I missed in the setup, any ideas? Thanks Dominic

Hi Scott, Referencig this doco: http://media.netapp.com/documents/tr-3747.pdf Best Practices for File System Alignment in Virtual Environments FIXING ALIGNMENT FOR MISALIGNED VMS HOSTED ON VMWARE ESXI In order to leverage the NetApp mbralign tool for correcting the file system partition alignment for misaligned VMs hosted on ESXi hosts, NetApp recommends leveraging a standby VMware ESX host and using a supported version of the mbralign tool to fix the VM alignment issues. This standby VMware ESX host should have access to the NFS/VMFS datastores hosting the misaligned VMs. Also, it is not required that this ESX host be part of the HA/DRS cluster hosting production VMs. I think you will have to install a temp ESX host to use the mbralign tool. Cheers Dominic

dominicb · ‎2011-01-31

"shutdown the virtual machine" my understanding is to shutdown the vm you are going to run the mbr tool against, not the vm that virtual center is running on. Is that what you mean? You can also check VM alignment from a Windows 2003 host without shutting it down by looking at: Start -> All Programs -> Accessories -> System Tools -> System Information Then expand Components section then expand Storage section and select "Disks" Look in the list of settings in right pane for Partition Starting Offset. If this number is divisible by 4096 then you are aligned. If it is not then you are misaligned. More details in here, page 80: http://media.netapp.com/documents/tr-3749.pdf

Hi Scott, This is covered in the install and admin guide for VSC 2.01 http://now.netapp.com/NOW/knowledge/docs/hba/vsc/relvsc201/pdfs/install.pdf Also covered in the ESX Host Utilities Kit install and admin guide. http://now.netapp.com/NOW/knowledge/docs/hba/esx/esxhu51/pdfs/install.pdf As you are using ESXI I think you should be referrring to the VSC guide rather than host utils. Cheers Dominic P.S. Make sure you have a backup before you run it.

Hi Clinton, That is useful info, thanks.

dominicb · ‎2011-01-13

Thanks for filing that, appreciate it. I'll keep an eye out, hopefully it will get added as I'm sure there are lots of people that will want this eventually.

Thanks for your help Vishal, in the end I have just loaded the rlm status output into an array using powershell and referenced the element for the firmware version. This gets me what I need for the time being. I would prefer to be accessing this info with a proper API call through a powershell cmdlet. Would you know if I could feed this back somewhere as an addition to a wishlist for pipeline work? Thanks Dominic

dominicb · ‎2010-12-16

Hi Vishal, No, that api relates to the system firmware, what I'm after if the rlm card's firmware revision (the management port). For example the output from a "rlm status" command through an ssh session on the filer shows the following: Remote LAN Module Status: Online Part Number: 110-00057 Revision: F0 Serial Number: 491341 Firmware Version: 4.0 Mgmt MAC Address: 00:A0:98:11:99:D6 Ethernet Link: up Using DHCP: no IP Address: 10.26.38.154 Netmask: 255.255.255.0 Gateway: 10.26.38.254 Any ideas which API can produce this output? Thanks Dominic

dominicb · ‎2010-12-16

I can't seem to find an API that exposes the firmware revision of the RLM card, it must be there somewhere....?!

For the English speakers he said he's got a 2050 cluster running 7.3.3 which he uses nagios and cacti to monitor but he's not sure what limits he should be setting as alarms for cifs ops, cpu and cache age. Bonjour, vous m'excusez mon francias a l'ecrit j'espere! a mon avis: CPU = moins de 75% CIFS LATENCY = moins de 20 milliseconds CIFS OPS = ca depend le nombre, type et vitesse des disques

dominicb · ‎2010-12-06

Check in the MMC that there are definitely no sessions locking the file. It should drop the lock when the cifs idle timeout is reached (default 30 mins). Restarting cifs will release it, however this will cause a service interruption to the cifs users so you would have to do it during a system downtime window. There is a KB on this scenario here: https://kb.netapp.com/support/index?page=content&id=2011588 In the meantime if they need urgent access to the file and can't open it you could get a copy back from a snapshot, if you have them enabled.

Hi there, Took a little while but I found the answer, there is a -P switch that got missed from the cli help, see below. For example I used: dfm report view -P 1m disks-performance-summary In cli there is an options to do this. The option is -P but some how this got missed in the cli help and man pages. This is fixed in one of the upcoming release(cli help and man pages) But still the option works in 3.7 and 3.8 releases of DFM. Below is the option name and its possible values. -P time frame signifies the period to fetch performance data. Valid values are 'last, 1d, 1w, 1m, 3m and 1y'. This option is valid only in conjunction with performance reports. Below is the help of the fixed cli. NAME view -- Generate one of several reports SYNOPSIS dfm report view [ <options> ] <report-name> [ <report-arguments> ... ] DESCRIPTION The report command runs one of several pre-defined searches and presents the results. Use 'dfm report list' to get the list of reports. Use 'dfm report view <report-name> help' to see the description of a report. The options are -g <group-id or group-name> -F <output-format> -l <lines> -q (quiet) -s <sortby-field> -x (show all fields; only in perl output format) -N <repeat-for> -i <repeat-interval> -t <timeout> (in seconds; for streaming reports) -H show deleted objects -P time frame signifies the period to fetch performance data. Valid values are 'last, 1d, 1w, 1m, 3m and 1y'. This option is valid only in conjunction with performance reports.
