FAS2xxx Upgrade - Flash Cache Performance Estimation?
by Stephen Stocke 30 Jun '15

30 Jun '15

Greetings We're looking to upgrade two sites which consist of a FAS2020 (7.3.7) and FAS2240-2 (8.1.4-7m) at each site. The 2240-2 systems have a FlashPool accelerated aggregate and the customer is happy with the performance. The new filers will be either a FAS2552 with additional shelves or we may ditch the entry toasters and go with a FAS8020 system and shelves at each site. If we go with the 2552 we'll keep using FlashPool. If we go with the 8020 we have the option of going FlashCache. We'd like to evaluate the potential performance improvements of using FlashCache on the 8020 in order to help with the purchasing decision. However, reading TR-3801 it looks like the FAS2000 and 2200 platforms don't support Predictive Cache Statistics (PCS). This is confirmed by trying to enable PCS: toaster> options flexscale.enable on FlexScale PCS is not active and cannot be enabled. Are there any other tools which can help us estimate the performance benefits of FlashCache? Or perhaps some key metrics we can collect and analyse?

NFS client info
by Mark Flint 30 Jun '15

30 Jun '15

Hello list, I’m trying to understand if it’s possible to get info similar to the 7-mode command nfsstat -l I apparently need to collect statistics with the statistics start -object nfs* -vserver svm But would like to be able to pinpoint the top 10 NFS hosts, could someone let me know how if they’ve worked it out, or commiserate if not :( ~Mark

cluster mode 8.2.3 / 8.3 dynamic home directory change
by Tomlinson, Thomas 30 Jun '15

30 Jun '15

Hi Toasters, I just stumbled upon a change in 8.2.3/8.3 with respect to the dynamic home shares and curious to get other folks views on it. Currently we make extensive use of the traditional static 7mode home directory share, cifs.homedir (\\filername\cifs.homedir<file:///\\filername\cifs.homedir>). This is further referenced behind DFS as a single link name with multiple targets. It works great, allows for all users to have a static username defined in AD, allows migration of filers without massive user updates, DR, etc. So life is good, or as good as it can be managing windows home directories. We're now slowly staring to lifecycle 7mode clusters to cmode, which has had a few hiccups, but I expected that . Prior to 8.2.3, you can replicate 7mode home directory functionality perfectly, even making up whatever static name you want. Fast forward to just recently when I was configuring a small cluster at a remote location. 8.2.3, sure slap that on. Configure the dynamic home directories, sure,errr.... no. A seemingly innocent entry in the release notes for 8.2.3 states that static names are no longer acceptable. A previously configured static share is brought forward and continues to function but you can no longer create new ones. Any new dynamic home share has to have the username in it (%w or %u). Needless to say this is a major change to our environment. Automation changes, massive AD updates (close to a nightmare with our IT organization) and a complete invalidation of our DFS namespace structure for home directories. Is anyone else similarly affected by this? I'm struggling to understand what twisted logic guided this coding decision.

check Global Status of a CDOT cluster using SNMP?
by Rue, Randy 29 Jun '15

29 Jun '15

Hello All, We're rolling out a pair of CDOT clusters and setting up Nagios monitoring. On our pre-CDOT clusters we check the global health of the filers using SNMP and the miscGlobalStatusMessage OID. It returns along the lines of: NETAPP-MIB::miscGlobalStatusMessage.0 = STRING: The system's global status is normal. In 8.3, even though the MIB that NetApp publishes for CDOT includes this OID, an SNMP query returns: NETAPP-MIB::miscGlobalStatusMessage = No Such Object available on this agent at this OID Anybody got any guidance? And if we're out of luck via SNMP, any ideas for an equivalent shell command I can pass via SSH? Hope to hear from you, Randy in Seattle

RE: OnCommand Performance Manager events
by Weihs, Yossi 29 Jun '15

29 Jun '15

Hello list, First post here … my role w/NTAP in the last three years has been with the OnCommand Performance Manager (OPM) program. For your first question – OPM 1.0 had many limitations, OPM 1.1 is the GA version and has many improvements in the troubleshooting analysis page. I can help you figure out 1.0 but we’ve fixed many of the confusing issues in it with the 1.1 release. We also have OPM 2.0 in the works coming out within weeks. I suggest you switch to 2.0 once it ships. It’s a much improved product. OPM 2.0 calculates an Aggregate and Node utilization metric, shows it front and center in the dashboard and allows you to set alert thresholds. All metrics in OPM 2.0 are hyperlinked with an explorer interface. As for figuring out what is pushing an aggregate, again there are improvements in 1.1 to help with that and 2.0 is MUCH BETTER (and yes I know I’m speaking loudly). All the best, Joseph "Yossi" Weihs Sr. Manager, Product Management Manageability Products Group NetApp “Simplicity is complexity resolved” - Constantin Brâncuși<http://en.wikipedia.org/wiki/Constantin_Br%C3%A2ncu%C8%99i> From: toasters-bounces(a)teaparty.net<mailto:toasters-bounces@teaparty.net> [mailto:toasters-bounces@teaparty.net] On Behalf Of Basil Sent: Thursday, June 25, 2015 8:51 AM To: toasters(a)teaparty.net<mailto:toasters@teaparty.net> Subject: OnCommand Performance Manager events I'm using 1.0.0 r2 with a CDOT cluster running 8.2.3. When I look at an event, it says things like "3 victim volumes slow due to 5 bully volumes causing contention on aggr_SAS". When I drill in, I can see a list of volumes with their latency at that period, but no indication whether they're being considered victims or bullies. Has anyone had any experience with this software? Another question- is there a way to look directly at an aggregate's utilization? If I drill into a volume, I can see the aggregate with "break down data by - components - disk operations", but that doesn't show me the aggregate itself. Just the contribution of this volume to the aggregate. When I look into an event, the aggregate utilization is listed, but I can't get to there on its own page with a controllable graph. Lastly, if I know an aggregate is being pushed to 100% but I can't see any volumes pushing harder, is there a way I can check whether system work is responsible? My first thought was that it was dedupe, but that's scheduled to kick off with the lowest possible priority about two hours after this event occurred. Cheers! Basil

cDOT 8.3: disk assignment
by Momonth 25 Jun '15

25 Jun '15

Hi, I've been configuring aggregates on 6 nodes cluster today and managed to assign a disk to a node that the disk is not "cabled" to, ie it sits in a disk shelf that is managed by a different HA-pair: na201::> disk show -container-type unknown Usable Disk Container Container Disk Size Shelf Bay Type Type Name Owner ---------------- ---------- ----- --- ------- ----------- --------- -------- 6.45.16 - 45 16 SAS unknown - na201node-3a The disk is "cabled" to na201node-1a, so I'm trying to change the ownership: na201::> storage disk assign -disk 6.45.16 -owner na201node-1a -force Error: command failed: Failed to assign disks. Reason: Disk 6.45.16 does not exist. OK, this time trying to remove the ownership: na201::> storage disk removeowner -disk 6.45.16 -force Warning: Disks may be automatically assigned to the node because the disk's auto-assign option is enabled. If the affected volumes are not offline, the disks may be auto-assigned during the remove owner operation, which will cause unexpected results. To verify that the volumes are offline, abort this command and use "volume show". Do you want to continue? {y|n}: y Error: command failed: Disk 6.45.16 is not connected to na201node-3a I'm out of ideas at this point .. any hints? Cheers,

NetApp and Unix UID
by Edward Rolison 25 Jun '15

25 Jun '15

Perhaps a slightly daft question, but I can't find the answer rummaging. Someone's just asked if there's a problem with going past 16 bit UIDs (>65535). Is anyone able to point me in the right direction?

Yes, and when I'm just looking to see what just happened, that's where I go. When I'm looking to have something light up at the command center to generate an off-hours page, though, we use specific SNMP software (HP Openview, to be specific) and we try to use it whenever possible.
