LTO5 drives and OnTap ?
by Paul Letta 17 May '10

17 May '10

Hello. Does anyone have any word on when LTO 5 drives will be supported in OnTap ? I'm getting an evaluation unit in a few days and was hoping to see it work with my FAS3040 with FC connections. I've never had FC tape drives on this 3040, the FC card has just sat there unused. I have had LTO3 SCSI drives attached to it. Does anyone have any experience with just connecting a new tape drive to an unused FC port like this ? I would like to think that the worst that would happen is that the 3040 just wouldn't see it, but I guess a filer panic could happen. We are a bit behind the OnTap curve, we are still at 7.2.6.1P3. We went to 7.3.1, but got hit with a filer panic loop due to linux clients hitting it with the rquota bug, so we had to downrev back. That was a while ago, but its left a bad taste for 7.3 for us.. Thanks, Paul

What exactly SMSQL does?
by Milazzo Giacomo 07 May '10

07 May '10

Hi all, I'm experiencing a lot of issues on a customer site where they've applied the Microsoft security best practice in a SQL2005 cluster environment. So that, the SQL Service account DOES NOT belong to the BUILTIN\Administrators group and DOES NOT HAVE sysadmin role on all the named instances. Most of issues have been fixed with SMSQL 5.0D2P2 and they belong to this http://now.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=358276 but nevertheless this we've discovered that the migration is only partial (not all the SQL directory structure is copied/moved on the NetApp LUN) because some path are missed after the migration wizard (i.e. LOG, REPLDATA...) and only the DATA path is migrated. Startup parameters still continue to belong to old paths and SQL Service Agent registry keys still continue to belong to old path!!! So we can fix the named instance to start but the SQL Agent will never be able to start. Worth, the ownership of dbs is changed to the user used as SMSQL service account! And the ACL on the file system is changed to it too! This has never been happened before on environment where SQL Service account belong to BUILTIN\Administrators and bug states that it should be also a domain admins!!! Terrible. This is a great security bug to have a service account belonging to domain admins! What I would to know is what exactly SMSQL does during the migration/configuration at level of properties of db (both system and user ones) and file systems. We can move the data manually on the right NetApp LUNs but to backup instances with SMSQL we must run the config wizard and I want to be sure that nothing will be changed.

raid group size
by steve klise 04 May '10

04 May '10

Hello Toasters! Ok, trying to understand somthing here. I have a V-series 3140 running DOT 7.3.2.p3. We reciently added a SAS card, and 2 new SAS shelves (450 flavor :)) When I go to create a new aggr, I only see 14 disk as an option for the raid group size. I dont have the option of raid4 or raid dp. I called support, and he said they changed this in the GUI to only have 14 as the max option as of DOT 7.3.1..... This does not sound right. yes, I know I can create an aggr, and change the raid group size. Just wondering if anyone else has experienced this, or have noticed this. -- View this message in context: http://old.nabble.com/raid-group-size-tp28441934p28441934.html Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

NDMPCOPY question
by David McWilliams 27 Apr '10

27 Apr '10

One of our files has a space in the qtree name and I'm struggling to execute an NDMPCOPY command on it. I have tried put double quotes & single quotes around the qtree name and the full path and a backslash in front of the space, but no difference, see below for an example; ndmpcopy -sa root:oldsys mis-netapp1:"/vol/vol1/education practice" "/vol/vol1/education practice" Ndmpcopy: Starting copy [ 17 ] ... Ndmpcopy: mis-netapp1: Notify: Connection established Ndmpcopy: fas3050: Notify: Connection established Ndmpcopy: mis-netapp1: Connect: Authentication successful Ndmpcopy: fas3050: Connect: Authentication successful Ndmpcopy: Failed to start dump on source Ndmpcopy: Done Sláinte, David "Build a man a fire he'll be warm for a day, set a man on fire and he'll be warm for the rest of his life" - Terry Pratchett Checkout my photos - http://www.panoramio.com/user/1113507

Some questioning about FlexClone
by Simon Vallet 23 Apr '10

23 Apr '10

Hi, we're currently considering the purchase of a FlexClone license for some of our database environment (MySQL 5, DOT 7.3.2, ~2TB data, growing fast), but I've been wondering if it provides the functionality we need. AFAICT, what we'll get with FlexClone is a read-write snapshot -- which is fine --, but the real question is about service migration between two copies : let's suppose we have a dev and a production database ; how would we migrate the service (e.g. a MySQL server) between the two? I realise hot migration will be complicated to implement, but do some of you already have played with this kind of things before?

routing issue with 2 vifs on same subnet?
by Romeo Theriault 22 Apr '10

22 Apr '10

We recently upgraded our SAN ethernet switches and moved from a config where we had one vif with all the nic ports on one switch to a config where we've split the nic ports out across the switches. So we now have two vifs split across the switches. Both vifs are on the same subnet and they have separate ip addresses as our switches don't support cross-switch etherchannelling. We currently have everything going through vif1 and this is working just fine. The issue is starting when I start trying to access the second vif, vif2. I can ping vif2 fine, ssh into vif2 fine but when I try to nfs mount an export on vif2 it hangs, waiting, waiting... then mounts it after about 30 seconds (on linux, solaris hosts don't seem to every mount it). But this only happens from some hosts. Other hosts can mount their exports on vif2 just fine. I took a tcpdump of the process and what appears is happening is vif1 is responding to requests to vif2, for a while, and then eventually responds out of vif2 and the linux servers is then able to mount the export. I've tried disabling fastpath and this didn't help. I then started thinking that I possibly need to have the vifs on seperate subnets but netapp support has verified that it should work fine on the same subnet. I'm not getting anywhere fast with netapp support so thought I'd see if anyone else has any ideas. Thanks, -- Romeo Theriault

FC port fan-in
by Fred Grieco 20 Apr '10

20 Apr '10

Toasters, I am looking at the specs for the Netapp 3140 cluster, and attempting to find the answers to two questions: 1) How many VMWare hosts can I have looking at the same set of LUNs? Before I have real-world performance issues? 2) How many multipathed hosts can I have, total, pointed at a four-fc-port cluster? The limit in #1, according to NOW, is 256 (256 initiators per igroup). What are your experiences in with this in large VMWare farms? #2 seems to be 256 according to NOW, but there is a limit called "FC port fan-in" of 64. This would seem to limit the total number of HBA initiators pointing at a port to 64, which, since all my HBAs see all my ports, would limit the total hosts to ... 64? What does this number mean effectively for hosts with two cards? TIA, Fred

NIC's
by Carl Howell 15 Apr '10

15 Apr '10

If NIC's like the X1037's and X1047's are OEM'd from some company like Intel, can I just go out and buy the Intel version and it will work? I've got some older filers I need to move off of fibre onto copper and was hoping I could just purchase the manufacturer's version and save some money. Thanks, Carl Howell Systems Engineer Information Technology Services University of West Florida
