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

If the volume is snapmirrored be careful about wild cards, and forcing deletion of all snapshots. If so, you may want to include something like "-snapshot !snapmirror" -Jeff ********************************************************** Electronic Mail is not secure, may not be read every day, and should not be used for urgent or sensitive issues

CDOT events and monitoring with unified manager
by Basil 03 Mar '15

03 Mar '15

Hi folks, I'm looking at using unified manager to manage alerting for CDOT. Does anyone know whether it will immediately perform the defined action when the event is issued by the storage, or does it have to wait 15 minutes for a sync?

Thanks for the clarification and no, these systems aren't licensed for SnapDrive, nor are the Filers (a 8.1.x 7-mode HA pair).

Thanks for the suggestion, I'll have to look into this. I forgot to mention that I'm not a Windows admin, but always willing to learn. I'm a Unix/Linux and Netapp storage guy. Are there any tricks to be aware of when installing this? Benjamin> NetApp Powershell Toolkit? There's a 'get-NaLun' cmdlet.

DS2246 PSU removal unnoticed
by Momonth 27 Feb '15

27 Feb '15

Hi All, I've been testing a few monitoring scripts for cDOT and had to pull out some physical components on heads / disk shelves, I noticed the following: when a PSU removed from a DS2246 disk shelf, this fact is not visible for CLI tools like "alert" or "system health". Also Zephyr API calls of 'ses' category don't seem to have visibility on that. So currently there is one disk shelf running on a single PSU and cDOT is quite happy about it. The disk shelf has an amber light on and there was the following event log entry once the PSU was removed: 12/19/2014 11:05:15 na101node-1a WARNING ses.status.psWarning: DS2246 (S/N SHFHU1427000371) shelf 24 on channel 0b power warning for Power supply 1: not installed. This module is on the rear of the shelf at the bottom left. It's running cDOT 8.2.2 Did anyone have similar experience? Is it expected behavior. Cheers, Vladimir

Adding disks to existing aggregates
by Woods, Bill 26 Feb '15

26 Feb '15

Hello toasters, A few weeks ago, I had the opportunity to destroy an aggregate in order to consolidate capacity. I started off with two aggregates, each with two RG and both aggr were 600GB drives only the older drives were FC/15K whereas the new aggregate is SAS/10K (I know you can mix RPMs and I'm ok with that). What I'm not ok with is what happened when I attempted to add 8 drives to the new aggregate. The current RG size was 12 and there were 12 drives in the first RG and 11 in the second, I then changed the RG size to 16 and added the drives to the aggregate (expecting to add 4 in each RG). But what really happened is that OnTap added 5 drives to RG1 and created RG2 with the remaining 3 drives. Support couldn't find any documentation on this and (I knew this) that it could only be corrected by destroying the aggregate. Have any of you experienced this?
