SSLv3, POODLE, and NetApp...
by RM 14 Mar '15

14 Mar '15

My apologies if this has been discussed. I searched the archives and didn't come up with anything. Customers are asking about disabling SSLv3 due to the POODLE vulnerability. Looking over the kb articles, NetApp's guidance is rather sparse. Has anyone disabled SSLv3 in their storage environment and if so, what did you see? I have a preliminary report that the vSphere side of things has some issues when SSLv3 is disabled but I don't have reliable details yet. Best to all, RM

Symantec Enterprise Vault + OnTAP based DR
by Momonth 12 Mar '15

12 Mar '15

Hello, I'm currently working on implementing DR for Symantec Enterprise Vault (EV), all EV data partitions are on NetApp filer (EV's SQL instance is out of the scope here), being accessed via FCP. I was hoping there was EV plugin for NeApp SnapManager, but it's not the case, also Symantec don't provide anything in that regard. I wonder if anybody looked at EV + SnapMirror integration? What were your approaches? My idea so far: 0. Setup SM jobs for EV volumes. 1. Set EV into 'backup mode'. 2. Trigger SM update for the EV volumes. Steps 1. ans 2. can be triggered from a powershell script, I think. Cheers, Vladimir

CDOT CIFS shares import?
by Basil 12 Mar '15

12 Mar '15

Does anyone know of a clean way to import CIFS shares? In 7-mode, I'd manipulate the /etc/cifsconfig_share.cfg directly if I ever needed to, but in CDOT, there's no such thing. I'm trying to plan a cutover from an EMC NAS to a Netapp SVM, and once we've got the shares on the Netapp configured and have done our final robocopy, I need to unjoin the SVM from the domain and rejoin it with the computer account of the old EMC. Doing this causes all the shares to be deleted. If there's no clean way to do this, I'll be building a command file of vserver cifs share create commands, but I'd really prefer not to have to. Thanks!

Can I still mount what used to be /vol/vol0, aka root volume from NFS SVM and read /etc/messages?

Shelf recognition problem with DS14s
by Jeff Cleverley 10 Mar '15

10 Mar '15

Greetings, My apologies for the long email but I'm trying to put in as many details as possible. I have some DS14 shelves attached to some 6290s running 8.1.2P4 7-mode. I've run into an odd problem that I think will require a takeover/giveback, but wanted to see if I've missed anything. I'm pretty sure the problem is not the shelf IDs :-) Controller A sees all disks and shelves through the loop just fine. Controller B sees both paths, but for the shelf number and bays, it only shows question marks for those. All connections are on PCI HBAs, nothing is using the onboard ports. Here is an example of the storage show disk -p command from Controller B: 9d.82 B 8d.82 A ? ? Here is the same path on controller B using a sysconfig -a: 82 : 0.0GB 0B/sect (Startup failed.) As you can see, it sees device 82 down both paths, but it can't identify the shelf or the drive bay. When I look on controller A, it has valid information. If I at a disk from controller B, it won't see any information on the disk like serial number, disk size, firmware, etc. Controller A sees everything just fine and does not have any Startup failed messages. If I do a storage show disk -n, controller A sees 84 drives, but controller B only sees 4. Those 4 don't show correctly either. If I manually pull a drive and reseat it, it will show up as an unowned drive with no valid shelf or bay slot. It will show up correctly in the sysconfig -a output. Here are things I've tried with no luck. 1. New FC ports on the filer side. 2. Reseating the shelf interface cards on both shelves 1 and 6 where the FC connections come in. 3. New fibre cable between shelf and filer. 4. Swapped controller A & B connection in shelf #1. Controller A sees everything correctly down the same path that controller B doesn't. Controller B doesn't see anything correctly down the path controller A was using and seeing everything. 5. Manually pulled a drive from a shelf and plugged it back in. 6. Verified I am not at any maximum number of drives or shelf count per cluster limit. 7. Verified both heads have the same shelf/drive firmware and qual_devices packages. The only thing I can think of is somehow the registry or something on controller B has corrupted. Since I have a head in an odd condition for this loop of disks only I'm a little reluctant to do a takeover and giveback. What if it comes back and doesn't recognize any of its drives :-) Thanks, Jeff -- Jeff Cleverley IT Engineer 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

Thank you all who reposned on rsh and ssh question, I did see rsh in firewall policy so I was woundering if that is still possible.

CDOT snapshot thoughts
by Mark Flint 04 Mar '15

04 Mar '15

So, I have a user who want me to turn of snapshots, and delete the old ones, across about 100 areas, all of over 10TB in size. No problem says I….. then my poor brain starts to think about how I could do this using the available policies. A colleague suggested altering the specific protection policy applied to these areas, so that the policy has zero snapshots kept, with the thought that it would slowly ‘age them out’. Turns out not, or that’s the way it looks at the moment. So, I’m left with a couple of options, basically, manually delete all the snapshots via script, and turn off snapshotting completely on those areas, and reduce the snap reserve to zero…..or hope the policy will do some magic for me overnight. Anyone think of a better way to do this? Happy Tuesday! ~Mark mark.flint(a)sanger.ac.uk

sanlun on Windows?
by John Stoffel 03 Mar '15

03 Mar '15

Guys, Trying to map LUNs presented to a Windows host back to the source Netapp Volume/Lun using something equivilent to the 'sanlun' command I can use on Unix systems. I tried installing the Windows HUK (Host Utilities Kit) but burried in the release notes is a cute little statment that 'sanlun' isn't available on there. Is there *any* tool which I can use from Windows to show me the Netapp volume and lun name from the Windows side of things? Thanks, John
