Restricing Protocol Access
by Bill Holland 15 Jan '08

15 Jan '08

Is it possible to restrict NAS protocol access to specific interfaces? Something akin to: options iscsi.options.access if!=e0b This prevents iSCSI access on interface e0b. I would like to do something similar for CIFS and NFS.

Does Snapdrive require CIFS?
by Hadrian Baron 15 Jan '08

15 Jan '08

Hi Toasters, We have a filer we'd like to make full SAN only but weren't sure if Snapdrive would work after pulling off the CIFS license. I know there's been some talk about a limited CIFS license, and am pretty sure Snapdrive only uses CIFS to make the initial connection, but once the LUN is mapped you can bounce CIFS or Snapdrive and the LUN stays mapped... It just feels crazy to renew CIFS on a SAN only filer. Thanks for your input, Hadrian

convert from plain link to vif with minimal downtime?
by John Stoffel 10 Jan '08

10 Jan '08

Guys, I've got to convert some filers from single links to VIFs to my cisco switches. I know I can do this with some edit to the rc file and a reboot. Can I do it with the system up and with minimal disruption to NFS traffic? Or should I just look for some downtime and reboot? Basically, I've got a single link on e11a now. I'd like to vif e11a and e11d. So, from the console could I do: ifconfig e11a down vif create multi v1 -b ip e11a e11d ifconfig v1 <hostname> And be done with it? I assume I might have to make some changes on the Cisco side as well, but I'd like to minimize my outage if possible.

AS/400 data on NetApp storage?
by Kevin Parker 08 Jan '08

08 Jan '08

Toasters: Are any of you (or know of anyone) running AS/400 system with storage on NetApp? If so, how is the configuration? What is your experience? I haven't found much support for it both off NOW and searching publicly... Best regards, Kevin M.

Incredible shrinking volume
by Stephen C. Losen 03 Jan '08

03 Jan '08

I have a fas270 with a volume named "san" containing one qtree and one LUN within the qtree. There is only one aggregate and it contains volumes "san" and "vol0" (root). The san volume is being synchronously snapmirrored to another fas270. Here are the sizes of everything: df -A Aggregate kbytes used avail capacity aggr0 1253187072 1200347772 52839300 96% aggr0/.snapshot 0 0 0 ---% df Filesystem kbytes used avail capacity Mounted on /vol/vol0/ 16777216 349732 16427484 2% /vol/vol0/ /vol/vol0/.snapshot 4194304 64892 4129412 2% /vol/vol0/.snapshot /vol/san/ 1119669456 1048001824 71667632 94% /vol/san/ /vol/san/.snapshot 58929968 102176 58827792 0% /vol/san/.snapshot lun show /vol/san/vmail/lun0 900.1g (966503301120) (r/w, online, mapped) I got an autosupport email saying that the san volume had run out of space, and it was indeed 100% full. I grew the san volume a little bit and I also reduced the snap reserve to 5%. Now as I watch the "df" output the san volume continues to slowly consume space. As I understand it, the LUN is a fixed length file, so it cannot be growing. I can only conclude that WAFL metadata files in the volume must be growing, perhaps as a result of the LUN being populated with data, or the snapmirror, or both. I'm concerned that I'll run out of space again in the volume, at which point I am just about out of options for enlarging it. Does anyone know what's going on here? As I have written this email, the space available in "san" has gone from 71667632 down to 71245556 and it's been dropping slowly and steadily for hours. Does anyone know what's going on here? Will I hit bottom before running out of space again? Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

R200 aggregate reallocation
by Eino Tuominen 02 Jan '08

02 Jan '08

Hi, I had to add just 2 disk to an existing aggregate. I suspect those disks will end up being a performance bottleneck, so I tried to start reallocation of the aggregate: toaster> reallocate start -A aggr0 Unable to start reallocation scan on 'aggr0': Aggregate created on older version of ONTAP What's the best way to proceed? -- Eino Tuominen
