19 Nov '15

teamctn_vols is the name of the volume on cfs1a that holds your volume. \\cfs1a\tcvols maps to this area. Current usage is 286GB out of 450GB. So plenty of space. There are no quotas turned on for this volume. Paul

AW: How to verify the health of all disks?
by Alexander Griesser 13 Nov '15

13 Nov '15

Hi, I've now updated qual_devices and installed the most recent disk firmware files; hammer did not find any issue, disk maint found two failed disk, the others seem to be good. Also, for whatever reason, running `disk_fw_update` with the latest files installed succeeded in installing the firmware on all of the 4321 disks, so it looks good now. Thanks!

Since it is an empty filer, you might be able to use qual_devices to fake out the system enough to let you update the firmware. I've never run into the 4321 bug, but qual_devices is what tells the filer about what kind of disks it has. I've seen issues before where the qual_devices files weren't updated and that caused new disks to not be recognized.

How to verify the health of all disks?
by Alexander Griesser 11 Nov '15

11 Nov '15

Hi Toasters, I had a pretty stunning experience on a customer's used filer installation yesterday, long story short: FSA2040 with 1xDS4243 24x1TB SATA disks, had to reinitialize the whole system because controller and shelves have been procured from different sources, so there was no root volume, etc. After I figured the disk reassignment out and have wiped both filers, they both booted up with a 3 disk aggr0 raid_dp and I could start to work on it. I then added a bunch of disks to filer #1 and continued with the configuration, until I found out, that some of the disks would not allow the firmware to be updated. The disks in question look like this: *> disk_list DISK CHAN VENDOR PRODUCT ID REV SERIAL# HW (BLOCKS BPS) DQ ------------ ----- -------- ---------------- ---- -------------------- -- -------------- -- 0d.11.2 SA:A NETAPP X302_WVULC01TSSM 4321 WD-WCAW30821984 ff 1953525168 512 N Working disks look like this: *> disk_list DISK CHAN VENDOR PRODUCT ID REV SERIAL# HW (BLOCKS BPS) DQ ------------ ----- -------- ---------------- ---- -------------------- -- -------------- -- 0d.11.0 SA:A NETAPP X302_WVULC01TSSM NA02 WD-WCAW31217461 ff 1953525168 512 N I've googled a bit and found out that disks showing up with REV "4321" need to be replaced, there seems to have been a series of disks in the past with this error, so what I did was I pulled one of those disks out of the filer and replaced it with another one.

WWPNs changing adaptors
by Edward Rolison 09 Nov '15

09 Nov '15

Hello admins. I'm hoping you can help me understand something confusing - I've got some FCOE (FCP) luns presented off a filer. We've been looking at doing some reconfig work, because the cabling wasn't right (we had 4a/5a cabled, and want 4a/5b). Anyway, to cut a long story short - we ran fcp portname show - and got a list of WWPNs and controller ids. We've looked again today, and it's changed - we're absolutely sure we had: 4a, 4b, 5a, 5b before (ascending WWPN order). Now they're 4a, 5b, 5a, 4b. And we can't quite figure out how or when they changed (we've had no outage on this kit). Is anyone able to enlighten me as to what might cause a wwpn swap?

Completely filling and aggregate
by Fred Grieco 07 Nov '15

07 Nov '15

Has anyone ever completely, completely (like with luns and overallocation) filled an aggregate? Were you able to reuse the aggregate again once you reduced the space (presumably by shrinking or deleting a volume or two)? Assume this is not the root aggregate. Putting aside how bad it is, how all the vols will fill and luns will go offline, how the performance will never be right, fragmentation, etc, this is recoverable, right? I'm testing a competitor's product- known for thin provisioning- and it completely went off the rails after I did this accidentally. I mean... Delete everything, start over, and a big fat "don't do that then" from support. TIA, Fred

Netbackup 7.6.0.1 backing up via NDMP cDOT 8.2.3 volume(s)
by John Stoffel 03 Nov '15

03 Nov '15

Hi, Anyone using Netbackup 7.6.0.1 to backup via three way NDMP, a CIFS share/volume on cDOT inside a VServer? It just ain't working for me. I suspect I need to upgrade to Netbackup 7.7, but before I go that route... I'm looking for other options. Basically, I want to have the NDMP data flow over the network to the Netbackup server, then from there to Tape. I don't have/want direct attached SAN tape drives at this time on our four node cluster. It's just one single volume I need backed up right now. Thanks, John

Slow SMB connections from 8.3 to some Mac clients
by Rue, Randy 03 Nov '15

03 Nov '15

You're been hearing from me a lot lately. We're having trouble with a small but distinct number of Mac users connecting via either CIFS or SMB and getting slow connections, an rsync of a test file shows a transfer speed of 500KB/s. Most of the problem children are older versions but at least one is running El Capitan, the latest greatest. On the clients that have the problem, they have it reliably. Sounds like a workstation issue but we're still hoping to give the users a solution. Anybody know of any known issues with Macs and CDOT 8.3? Solutions? Randy

Re: python API guidance for cluster mode CIFS share reporting/management
by Maarten Lippmann 03 Nov '15

03 Nov '15

Hey Randy and Richard, A quick note: I am in no way a programmer, I just pretend to be one when I need to get stuff done. My code is likely ugly. Covering most of the issues called out in this thread. The doc file error means zedi can't run the small handful of zapis that only exist in 8.3 or later as it does not yet know about them. It's not going to prevent zapis that exist in both zedi and 8.3 from working. Nor will it affect your abilities to run zapis with python or any language by hand. Before I share an example that works, a quick note on the page you linked: http://community.netapp.com/t5/Software-Development-Kit-SDK-and-API-Discuss… It talks about how when iterating through xml, from a data collection perspective you can either get a list of all children, or get a child object given the name, but there is no clear documentation on how to get the content of an xml element. This is of course a requirement to get stuff done. I struggled with this initially as well, and that page explained it enough to me to get stuff working. It's not really a bug, more a lack of clear documentation on the calls you can do on elements. For example, if you have this: <share> <name>awesomeshare</name> <path>/project/location</path> </share> You can iterate through the share children and get objects for the name and path (the children_get() call), or you can pull the name object specifically with child_get('name'), but you want that 'awesomeshare', or that '/project/location' property value, not just an object for the property/value combination. The documentation (still?) lacks a clear indication on how to get the value inside of an xml element. Zulanch answers it: you do a object.element['content'] to get that inside information. The python sdk code itself has not really changed in years it looks like, as it's a convenient wrapper around builtin xml libraries and is expected to work in the same form for all zapis for the past years (decade?). Here's a basic working python script example that pulls data over zapi to get you going, using that .element call extensively; it at least works against 8.3.1. http://pastebin.com/Kpm6nJmq The example script is very basic and creates a python list of returned elements with a python dictionary of properties for each one, much easier to handle in python than the raw xml returned by the sdk. It's a scraper, it does not push changes. The script is not optimal, especially if elements get really deep, but should work for most queries and can easily be extended. I bet libraries like xmltodict can do this in a more scalable way, I'm doing all the work by hand in this example. At least the raw code should give you a very good idea on how to make zapi calls work in python. I also cover the max records part and do subsequent calls that start where the previous zapi response left off to get that comprehensive table of data. Notes on script: It takes a cluster mgmt ip or hostname, and a zapi call as input strings. It uses NaServer and NaElement to get the xml. It has the default max records of 20 set to keep pressure on the cluster low in maintaining records in memory before returning to clients (management processes do not like to do too much work, imagine them having to keep thousands of objects in memory, each with hundreds of properties before they can return them, while a dozen other management tools are hitting the same cluster against the same node that hosts the cluster mgmt lif. I don't want to be complicit in an api DOS of my own system when pulling inventory if I don't need to be), but will continue pulling 20 items sequentially until all items for a given zapi are pulled (in below example the items are shares, but it can also get volumes, aggregates, ports, disks, lifs etc. with the associated zapi) Below lines pull in the script, invoke the function and print the output. The script depends on a creds file with a username and password. The script expects the relevant user to have ontapi (at least read only) access. (or do things your own way and modify it to use certs instead).

Anybody using OnCommand Performance Manager (OPM)?
by Rue, Randy 29 Oct '15

Our new 8.3 cluster is in production, finished migrating the last vservers to it last weekend, and suddenly we're getting ~6 alerts a day from an OPM server set up by a co-worker who's left the organization. I confess I've barely looked at the thing until now. Whenever I go to investigate the details of the latest "incident" I find that it's not a problem, i.e. latency on a volume "jumped" from <1ms to ~5ms. Looks like the application is looking for deviation from a dynamically determined baseline and I'm not seeing any option for tweaking parameters or limits. Six false alarms a day makes this effectively useless. Anybody else using this app? Got any tips on making it useful? Randy

python API guidance for cluster mode CIFS share reporting/management
by Rue, Randy 29 Oct '15

Hello All, I'm working on automating the synchronizing of CIFS shares on the vservers of one 8.3 cluster to their DR mirrors on another cluster. It occurs to me that this might be useful to other shops so I'm trying to up my game from my usual fairly sloppy code i.e. http://xkcd.com/1513/ with lots of SSH calls to the CLI and parsing text output sequentially, to something portable and standard enough to share. Taking a look at the SDK/API with ZEDI as a guide to the objects involved and having a tough time getting started (never used much XML either). To make things muddier, the API I'm looking at "cifs-share-get-iter" apparently has a bug (http://community.netapp.com/t5/Software-Development-Kit-SDK-and-API-Discuss…) that I don't totally get. Maybe if I could understand the object as it's supposed to work first. Any experience with the API? Looks like it's a few years old, is it used with 8.3? Hope to hear from you, Randy in Seattle
