RE: Dedicated ONTAP disks? (Fletcher Cocquyt)
by Woods, Bill 05 Jun '15

05 Jun '15

The latest install was configured with dedicated aggregates just for vol0 (NetApp Best Practice - especially for CDOT systems). If you have an issue where the aggregate containing vol0 (with data volumes) "drops-out" or loses multiple drives, you MAY NOT be able to recover that aggregate. Regards, Bill ------------------------------ Message: 3 Date: Fri, 5 Jun 2015 13:44:14 -0700 From: Fletcher Cocquyt <fcocquyt(a)stanford.edu> To: "<toasters(a)teaparty.net> Lists" <toasters(a)teaparty.net> Subject: Dedicated ONTAP disks? Message-ID: <77C0C02C-A86A-4EE8-B281-C41510845454(a)stanford.edu> Content-Type: text/plain; charset="utf-8" I?m curious how many admins dedicate 3 disks for ONTAP aggr0/vol0 vs having one big aggr0 and vol0 residing on the same aggr as the other data volumes? Is there a compelling reason to dedicate disks to ONTAP besides ?best practice? ? thanks

need some reallocate advice
by Rhodes, Richard L. 05 Jun '15

05 Jun '15

Hi, A bunch of IBM NSeries 3220 (NetApp FAS2240-2) OnTap 8.1.2p1 I'm about to start adding 2 disks to a bunch of NetApp systems - 2 disks into each system to expand CIFS shares. I will need to run reallocate to spread the vols in the expanded aggregates. There are around 30 vols in each aggr, some tiny and some a couple TB. Reallocate start -f -p /vol/<vol> How have you handled reallocate of a large number of vols in a aggr? Would you just start them all and let them run? If not doing them all at once, I could script them one at a time from AIX via ssh, but I don't see a "-w" (wait) option to allow easy single threading. I would need a loop to monitor for a particular reallocate cmd completes before starting another. I'd rather not get into that much scripting effort. Note that there is snapmirror and snapvault running every 6 hours on these vols. I don't want to hit the systems so hard that these have problems. Thanks!

cDOT Transition Mirror
by Martin 29 May '15

29 May '15

Currently I have some Filers running 7.3.7P1 7-mode mirroring with VSM to 8.2.3P1 7-mode Filers for DR. I know in the event of failing over to the 8.2.3P1 Filers a failback would involve using something other than VSM (Robocopy, RSYNC) as we wouldn't be able to reverse the snapmirror from 8.2.3P1-->7.3.7P1. The 8.2.3P1 7-mode Filers are going to 8.3P1 cDOT but some of the 7.3.7P1 7-mode Filers are not due for replacement. I was considering using the transitional snapmirror (TDP) to mirror from the 7.3.7P1 7-mode Filers to the new cDOT Filers. I realise this is one way but this isn't any worse than the current situation. Has anyone used this configuration or see any issues with this? I'm trying to avoid having to provision a 7-mode DR Filer just for a couple of minor remote Filers.

7-mode snapmirror question
by Basil 26 May '15

26 May '15

Hi folks, I have a 3170 running 7.3 snapmirroring volumes shared on vfiler0 to a 3250 running 8.2.1 7-mode. I want to start replicating a volume that needs to be owned by a vfiler on the 3170. Can I do that with the snapmirror service running on vfiler0? Or do I need to create a /etc/snapmirror.conf and all the other setup required inside the vfiler?

FAS8040: SP and e0M configuration
by Momonth 24 May '15

24 May '15

Hi All, I never used e0M on FAS32xx as it was limited to 100Mb, but decided to give a try on FAS8040. So, I've configured SP via DHCP (10.193.12.0/24), it's up and running and I can login onto it: na102::> sp show -node na102labnode-1a -instance Node: na102labnode-1a Type of Device: SP Status: online Is Network Configured: true Public IP Address: 10.193.12.31 MAC Address: 00:a0:98:68:00:18 Firmware Version: 3.1P1 Part Number: unknown Serial Number: unknown Device Revision: Not Applicable Is Firmware Autoupdate Enabled: true However having assigned an IP to e0M (from cluster management interface) doesn't make the e0M "ping-able". Here is my config (the same 10.193.12.0/24 is used): na102::> network interface show -vserver na102 -lif na102labnode-1a_mgmt1 -instance Vserver Name: na102 Logical Interface Name: na102labnode-1a_mgmt1 Role: node-mgmt Data Protocol: - Home Node: na102labnode-1a Home Port: e0M Current Node: na102labnode-1a Current Port: e0M Operational Status: up Extended Status: - Is Home: true Network Address: 10.193.12.44 Netmask: 255.255.255.0 Bits in the Netmask: 24 IPv4 Link Local: - Subnet Name: - Administrative Status: up Failover Policy: local-only Firewall Policy: mgmt Auto Revert: true Fully Qualified DNS Zone Name: none DNS Query Listen Enable: false Failover Group Name: Default FCP WWPN: - Address family: ipv4 Comment: - IPspace of LIF: Default It feels like e0M needs default gateway? How do I set it up then? Or Am I missing the whole idea here? Thanks, Vladimir

Linux OnCommand AD integration: group authentication
by Robb W. 22 May '15

22 May '15

Hi All, I have set up a couple of OnCommand servers to integrate with Windows AD for authentication. I used this NetApp Knowledge-base entry as my starting point: 1011398: How to configure OnCommand Unified Manager (Operations Manager) on Linux for authentication with Microsoft Active Directory The OnCommand servers are versions 5.2.1 (for 7-mode) and 6.2rc1 (for CDOT) respectively. Authentication of individual users accounts is working perfectly on both systems. But I cannot seem to get group based authentication to work ... On version 5.2.1 doing a "ldap find" returns this error: > linux:~ 22.05 15:07:00$ dfm ldap find Storage-Admin-Groupname > > Error: Searched under 'OU= ... ,' but didn't find administrator or group 'Storage-Admin-Groupname.' > > If 'Storage-Admin-Groupname' exists, one or more of these settings may be wrong: > ldapBaseDN, ldapUID, ldapGID, ldapUGID, ldapMember. > Templates can set all but ldapBaseDN to values that are probably compatible with your server. If I go ahead and add the group anyway, I get: > linux:~ 22.05 15:53:07$ dfm user add Storage-Admin-Groupname > > Warning: Storage-Admin-Groupname does not exist in the administrator database(s), so login is disabled for this administrator. > Added administrator Storage-Admin-Groupname. Doing a test operation via the version 6.2 Web UI returns a similar error. (Not surprisingly, since both systems are using the same settings.) Any tips on why this might not work, or suggestions on how to fix it? I assume that doing "dfm find group" like this should work? The (obfuscated) dfm options are as follows: ldapBaseDN OU=AdminUsers,OU=GlobalResources,OU=xxx,DC=yyy,DC=zzz,DC=xyz ldapBindDN oc-auth-account ldapBindPass ******** ldapEnabled Yes ldapGID memberOf ldapMember member ldapUGID CN ldapUID sAMAccountName ldapVersion 3 Thanks in advance for you help! Cheers, Robb.

ONTAPI - perf-object-get-instances multiple
by Edward Rolison 15 May '15

15 May '15

I've been experimenting with ONTAPI for some monitoring. I've found it seems to support sending multiple API requests in a single POST - which is useful, because then I can fetch an XML bundle that contains 'system-get-info', 'clock-get-clock' and then 'perf-object-get-instances' for multiple objects. There's just one slight problem - when I do this, I get back a bunch of 'instance-data' elements, which aren't actually named as to which objects they're from - just which instance name. Has anyone else come up with a good solution to this? Are the counter names globally unique, and thus mappable back to their parent object? Or am I just going to have to accept making multiple requests, and fetch my perf counters separately?

AW: ACP - missing IOMs
by Alexander Griesser 14 May '15

14 May '15

Thanks everyone, since the filer is a few hundred kilometers away ATM I was hoping for a remote fix ☺ System is MPHA of course and I verified that with Config Advisor as well as on the CLI, so that shouldn’t be a problem. Does it make sense to open a Case to make them aware of the fact? Could that also be a firmware issue on the IOMs or ACP that might be fixed by applying a new firmware? I’m not sure how firmware updates are applied to the IOMs – is that happening through the SAS cables or is ACP necessary for that? My idea was to start a firmware update on the shelves to see if that fixes the issue, since a firmware update also reboots the IOMs one at a time – but if ACP connection is necessary for the FW update to complete I’m out of luck here and will have to dispatch remote hands.

Using noninteractive ssh in Clustered Data Ontap
by Basil 14 May '15

14 May '15

I'm trying to use CDOT noninteractively from bash, but running into trouble. Let's say for example you wanted to get a list of volumes on an SVM and then sort by size- there's no sort in the interactive CLI and it asks you to enter text every page of results, so my initial thought was to send the command noninteractively and do what I need done in bash. If you send the command "ssh user@nas volume show -vserver whatever", you get a nicely formatted table without any of the line-splitting, confirmations, or other interactive shell nonsense: Vserver Volume Aggregate State Type Size Available Used% --------- ------------ ------------ ---------- ---- ---------- ---------- ----- svm vol1 aggr1 online RW 2TB 2.00TB 0% svm vol2 aggr1 online RW 100GB 100.00GB 0% This is much better, but I still can't use the size field to sort unless I can change it all to the same unit. If this were an interactive session, I'd use "set -units GB", however it's not. How can I accomplish that non-interactively? Can I send multiple commands in one ssh command? One thing that should work but doesn't is creating a list of commands that will run and sending them via ssh- me@myserver:/home/me $ cat temp set -units KB volume show -vserver svm -volume *root me@myserver:/home/me $ ssh admin@nas < temp Pseudo-terminal will not be allocated because stdin is not a terminal. nas::> set -units KB nas::> volume show -vserver svm -volume *root Vserver Volume Aggregate State Type Size Available Used% --------- ------------ ------------ ---------- ---- ---------- ---------- ----- svm svm_root aggr1 online RW 1048576KB 995796KB 5% nas::> me@myserver:/home/me $ As you see, as soon as it detects multiple lines, it switches back to the interactive shell. If I had use something with more than a single line of output, it would have given me a couple of lines, asked for "confirmation", and then exited. All the while putting "readability" whitespace inconsistently all over the results. Any ideas? Basil
