iSCSI best practices
by Kalra, Manish 25 Mar '13

25 Mar '13

Hey guys, Are there any iscsi best practices with Netapp? I am going to setup Oracle DB on LUNs which will use iscsi. I am mostly concerned about redundancy and how iscsi behaves during filer failovers. Manish

Separating management and data traffic (e0M vs replication interfaces)
by Chris Picton 25 Mar '13

25 Mar '13

Hi all I have two pairs of 3210s. The default gateway of the systems are via the management interface IP range, so that they are reachable remotely on the e0M interfaces. However, this is causing snapmirror replication to use those interfaces as well, which is undesirable from a speed/data path persepctive. I have considered putting e0M into its own ipspace, but then how would I manipulate its routing table as it would not be in a vfiler. Any other ideas about having e0M reachable from anywhere, but still use a different vif as the default gateway for generic traffic on the system? Chris

RE: Separating management and data traffic (e0M vs. replication interfaces)

What you can do is modify your rc file so that the other networks that are non-production would be defined first and set appropriate routes. Then leave defining e0M for after the others are defined. Also, depending on your ONTAP version, there are the options to limit/prevent protocol or snapmirror traffic over certain interfaces "options interface.xxxx.blocked". Regards, André M.

FCP FAN IN QUESTION
by Milazzo Giacomo 21 Mar '13

21 Mar '13

Hi all, we're setting up a very large FCP environment on a 6240HA with 4 target HBA each dedicated to that SAN. Hosts are IBM AIX LPAR each with 4 NPIV HBAs coming from two different VIOS. We will have more or less 300 LPARs. Both NetApp controllers and hosts are simmetrically zoned and divided on two FC switches, as usual. Well, the FC & iSCSI Configuration Guide report the limits for each family of controller and for 6200 one the FC port fan-in is 64. Is it really the maximum number of hosts they mean? Not the inititators number? I ask it because if you look at the current fcp stat you can see we already have roughly 40 initiators connected to each target and we'll quickly reach that limit. If that is the host number we can easily add more target ports to balance workloads...but if that number is "initiators" we're in trouble. Thanks in advance, Regards V6240A*> fcp stats Statistics for adapter 0c Read Ops: 142646 Write Ops: 5387410 Other Ops: 5501 KBytes In: 606619208 KBytes Out: 18650223 Adapter Resets: 0 Frame Overruns: 0 Frame Underruns: 0 Initiators Connected: 0 Link Breaks: 2 LIP Resets: 7 SCSI Requests Dropped: 0 Interrupts: 20804631 Spurious Interrupts: 0 Total Logins: 415 Total Logouts: 415 CRC Errors: 0 Adapter Qfulls: 0 Protocol Errors: 0 Invalid Transmit Words: 0 LR Sent: 0 LR Received: 0 Discarded Frames: 0 NOS Received: 1 OLS Received: 8 Queue Depth: 0 Statistics for SFP on 0c Vendor Name: FINISAR CORP.

Upgrading 32->64 bit aggregates/vols without adding disk
by Fletcher Cocquyt 21 Mar '13

21 Mar '13

Again in the position where my source aggregate is 32 bit and destination is 64 bit and this prevents vfiler online migration. Last year this was a priv set diag command aggr 64bit-upgrade start aggr1 -mode grow-all http://www.gossamer-threads.com/lists/netapp/toasters/11820 In test mode, this completed the 64 bit upgrade quickly and without error. Anyone done this in production? (Ontap 8.1) thanks

Changing qtree security type on snapvault destination.
by Jeff Cleverley 20 Mar '13

Greetings, How do you change the security style of a snapvault destination from ntfs to unix? The qtree is currently ntfs as is the primary qtree. When I try to change the security style it just says it change change it. How can I change it so I can see the qtree via nfs from our admin server? Thanks, Jeff -- Jeff Cleverley Unix Systems Administrator 4380 Ziegler Road Fort Collins, Colorado 80525 970-288-4611

File Access / Size Usage Reports
by Ray Van Dolson 13 Mar '13

13 Mar '13

We have several large CIFS shares managed by internal departments. I'd like to be able to get reports based on which directories contain the most data / files (inodes) and also which files aren't being accessed very frequently and as such are candidates for archival / deletion. We've historically used CommVault's SRM for the latter, but the Backup team is telling me it won't work on CIFS shares as it needs an agent. Essentially looking for something like JdiskReport plus file access reporting. Could probably run tools direct from OS's accessing the shares (and that may be the right thing to do). Am wondering what all of you use out there? Ray
