Cyber Liability and Data Breach insurance Coverage
by Mike Linett 02 Jan '15

02 Jan '15

Hi: We have spoken to our business insurance brokers about cyber liability and data breach insurance and they assure us that our internal storage is covered, but they will not cover data stored in a 'cloud provider' against cyber liability and Data Breach. Has anyone found a commercial insurance package that provides cyber liability and data breach coverage for data located on a commercial service like Salesforce.com?

where are folks planning to migrate their storage spending to in the new year?
by Fletcher Cocquyt 30 Dec '14

30 Dec '14

Happy holidays and 2015! Curious, where are folks planning to migrate their storage spending to in the new year? Here we have new agreements with several cloud vendors - "unlimited cloud storage" - so mgmt's expectation is we somehow stop buying netapp and move to cloud storage. I've had very mixed performance (throughput drops off drastically) and reliability results with initial tests mounting cloud datastores (using rsync to archive server data - anyone had better results?) Given our VMware centric workloads, I'd be leaning towards investing in local, 10G connected server storage with an eye towards VSAN Are there other vendors with a compelling story (SSD/cache) you are considering to migrate to? We are on latest vmware 5.5, ontap 7.1.2 and Dell 620/720 vmware clusters. thanks for any feedback, tips!

Conflicting Recommendations?
by Philbert Rupkins 30 Dec '14

30 Dec '14

Toasters, It appears the following documents conflict with one another when it comes to recommendations for the value of Net.TcpipHeapMax in ESXi. ---------------------------- *How to configure VMware vSphere 5.x for Data ONTAP 7.3 and 8.x* https://kb.netapp.com/support/index?page=content&id=1013275 Net.TcpipHeapMax For vSphere 5.0/5.1 set 128 For vSphere 5.5 set 512 *TR3749 - NetApp Storage Best Practices for VMWare vSphere* http://www.netapp.com/us/media/tr-3749.pdf "While the NetApp best practice remains to set Net.TcpipHeapMax at the maximum value of 128MB, tests have shown ESXi 5 to be less sensitive to depletion of TCP/IP heap memory." ---------------------------- It seems that TR3749 may be out of date (last update 2011) as it doesnt distinguish between vSphere 5.0/5.1 and 5.5. To my knowledge, the 128MB maximum TCP/IP heap size is applicable to vsphere 5.0 and 5.1. I believe 5.5 increases this maximum to 512MB. I assume the current recommendation for vSphere 5.5 against a filer running ONTAP 8.1.4 7-Mode is 512MB. Can somebody confirm? Is there a best practices doc like TR3749 for vSphere 5.5 in a 7-mode environment? Thanks, Phil

Re: new cdot NFS vserver. NFS mount point hang on I/O
by Jeff VanDeRyt 22 Dec '14

not sure what version you are on, but our fastpath comment reminded me of a entry in the Clustered Data ONTAP® 8.2.1 Release Notes: ---------- Disabling fast path in some networking environments Fast path is enabled by default in all nodes in the cluster. However, you might have to disable fast path in certain environments in which fast path does not function optimally. About this task IP fast path is a mechanism that uses the network interface of an inbound request to send the response quickly by bypassing a routing table lookup. Fast path is enabled by default for all TCP and NFS over UDP connections. You might have to disable fast path if you are working in configurations of Cisco vPC, HP NIC teaming, or asymmetric routing environments. Steps 1. From the nodeshell, enter the following command: options nodescope.reenabledoptions ip.fastpath 2. To disable fast path, enter the following command: options ip.fastpath.enable off For more information, see the bug ID 494396 in Bugs Online on the NetApp Support Site at support.netapp.com/NOW/cgi-bin/bol. ---------- IP Fast path feature is incompatible with some networking environments http://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=494396 ********************************************************** Electronic Mail is not secure, may not be read every day, and should not be used for urgent or sensitive issues

CIFS and NFS file names
by scl＠virginia.edu 12 Dec '14

12 Dec '14

Hi folks, We recently copied some netapp volumes to a non-netapp file server via NFS and rsync. Unfortunately we have now converted a lot of file names that were created via CIFS on the Netapp using a variety of character sets, such as Arabic, Cyrillic, Persian, etc. As I understand it, a Netapp keeps two file names for each file/folder. The CIFS filename is 16 bit Unicode while the NFS filename is "literal" 8 bit characters (i.e., not UTF-8). I presume that when a file is created on the Netapp via CIFS that the Netapp creates both the CIFS filename and a NFS filename. When we copied the volumes via NFS and rsync, the NFS names were copied over, so we "lost" the CIFS names. Is there any algorithm or procedure that we can use to convert these 8 bit "NFS" names to their equivalent 16 bit Unicode names? Ultimately we need to convert to UTF-8 which is what the destination file server uses for file names (both NFS and CIFS use the same UTF-8 filename). We have turned off CIFS access to the Netapps, and I would like to avoid turning it back on, but I may have no other way to retrieve the original 16 bit unicode names. The Netapp volumes are Unix security style and were accessed both by NFS and CIFS. Some files were originally created via NFS, some by CIFS. And unfortunately, some CIFS filenames had non-English character sets. Here are some sample NFS filenames. I have no idea what the corresponding CIFS filenames are or what character set. :31K4J00 :44O8K00 :5J0TA00 :8QLDT00 :BQLDT00 :EA0IL00 :FA0IL00 These look like the result of a hash, so there may be no way to convert back to CIFS 16bit Unicode.

Time to Update Health Summary on MyAutoSupport
by Philbert Rupkins 11 Dec '14

11 Dec '14

Toasters, After initiating a manual "WEEKLY_LOG" autosupport, how long does it take for your MyAutoSupport site to update? Specifically, the "Health Summary" section that includes the High (red), Medium (amber) and low (yellow) status indicators. The Health Summary section of MyAutoSupport is really helpful. We regularly use the Health Summary to determine when we need to perform disk/shelf firmware upgrades. However, after performing a disk/shelf firmware upgrade the Health Summary section only appears to get updated on Sunday. Even performing a manual "autosupport.doit WEEKLY_LOG" doesnt seem to update the Health Summary section w/in 24 hours - we have to wait until Sunday to see the updated Health Summary. Just wondering if this is similar to your experience as well. Thank you! Phil

SnapLock Compliance question
by Eric Peng 08 Dec '14

08 Dec '14

Has anyone worked much with SnapLock Compliance license? Because our purchase cycle may take a bit longer than planned, we are considering creating our SnapLock Compliant aggregate/flexvol using a 30-day trial license, and then add the full purchased license later. My question is whether the compliance clock and/or the WORM state of the data would be impacted once we remove the trial license key and attempt to add the full license key to the filer? I'm suspecting there should be no impact, but wanted to verify with all of the SnapLock gurus out there. :) I found KB 3010993 on the NOW site which only addresses the removal of a SnapLock license, which does not entirely cover the scenario I describe.. Thanks, Eric

Maximum Total End-to-End Distance for SAS Copper?
by Philbert Rupkins 02 Dec '14

02 Dec '14

Hello, Does anybody know if there is a maximum end-to-end/point-to-point distance for *SAS copper* cables in a stack? The Universal SAS Cabling Guide provides the following maximum distances for SAS optical but makes no mention of a maximum distance for SAS copper. *If you are using SAS optical multimode breakout cables, the following parameters apply:* *• The point-to-point (QSFP-to-QSFP) path of any multimode cable cannot exceed 150 meters* *for OM4 and 100 meters for OM3.* *• The total end-to-end path (sum of point-to-point paths from the controller to the last shelf)* *cannot exceed 510 meters.* Just wondering if there is also a maximum for SAS copper. Thanks, Phil

NDMPcopy on 7.3.4p4
by Basil 28 Nov '14

28 Nov '14

Hey folks, I have an old filer that I can't do a firmware upgrade on (it's being replaced in the next 6 months) where I need to move data from a qtree to its own volume. I would like to investigate the ndmpcopy command for this, however when I do this, the one CLI interactive session that the filer has is taken up. We can't do any more interactive commands on the filer, and if we press ctrl-c, the ndmpcopy is killed. I don't want to test this on my prod box and my nonprod boxes are all running newer firmware, but does anyone know whether we can kick off an ndmpcopy using a non-interactive command? Would we be able to cancel it after starting it? Thanks, Basil
