Multiple (more than 2) controllers in a cluster
by Philip Gardner, Jr. 11 Jun '15

11 Jun '15

Hi all - We are currently building out a new space (long time in the making), and some employees have come and go in between the process. We ended up with a 2240, a 3250, and an 8040. The 8040 is fully updated with CDOT 8.3. We are now preparing to do the same to the 2240 and 3250. The 2240 has the 10Gb mezzanine card, and the 3250 has two 10Gb PCI cards. I'm still learning, basically as I go, but does it make any sense to put all these filers in the same cluster? If not, does it make sense to use the CN1610's for each of the filers' cluster connections? I'm trying to think of a reason the 2240 needs to be in the same cluster, but can't really think of one. The 3250...maybe, since it is a decent amount of power. I know from some of the docs I've seen that the 2240 can use one of the 10Gb ports to connect to the other head in a non-redundant fashion, while still allowing the use of the other 10Gb ports for the data connection. Googling for things about multiple filers in the same cluster is difficult, or no one is talking about it. Thoughts or ideas? -- GPG keyID: 0xFECC890C Phil Gardner

Hi all, Has anyone ever seen these messages or know what causes them: lmgr.hosts.maxedout: Number of hosts active 50000 has reached the maximum number of hosts supported 50000. No additional host structures can be created. Thanks! Brad

Disk auto assign
by Edward Rolison 11 Jun '15

11 Jun '15

I've just added some new shelves to a (7-mode) filer pair, bring them up to two stacks of 10 shelves. I'm trying to get 'autoassign' working, and it isn't. I have: - swapped drives such that each 'head' has only disks from one 'stack'. Head 1 has 0a/5b Head 2 has 5a/5d I've had to manually trigger a small number of 'replace' operations. And then switched on autoassign in the options. I _think_ that should be it, but ... there's something I'm missing, because autoassign isn't working. Does anyone have suggestions for why this might be, or what else I could check? (I'm wondering if there's a misassigned but 'failed' drive that otherwise isn't showing up?)

cluster OS vs 7-mode
by Iluhes 11 Jun '15

11 Jun '15

For years I been complaining how much I dont like Cluster OS over 7-mode.I been telling netapp folks to keep 7 mode as an option and parallel OSThe storage field is evolving and there are so many more options now and reading this, looks like people are might voiting against cluster OS with their feet.

Dedicated ONTAP disks?
by Fletcher Cocquyt 06 Jun '15

06 Jun '15

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

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.

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. Thanks Martin -- View this message in context: http://network-appliance-toasters.10978.n7.nabble.com/cDOT-Transition-Mirro… Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

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
