SL SMB misery
by Carl Howell 25 Jun '10

25 Jun '10

Like many of you, we have been having lots of weird issues with Snow Leopard and SMB. We've upgraded to 7.3.3, but that hasn't helped. A lot of the symptoms we are experiencing are mentioned here: http://discussions.apple.com/message.jspa?messageID=11041594 For those of you that are having these problems, what are you doing to try to solve them? Thanks, Carl Howell Systems Engineer Information Technology Services

I: Snapdrive 6.2 and Net.TCP Port Sharing Service Issue
by Milazzo Giacomo 25 Jun '10

25 Jun '10

I've not surrended myself to Microsoft nightmares!!! :) With the help of Process Monitor I was able to find where that damned service fails (if not administrator). I don't know the reasons but installing and or patching .net 3.5sp1 (and of course the related patches to the 3.0 and 2.0 too) on a Windows 2003 italian (or other than eng) does not fix the permissions needed from this service on file system. There's a system folder where the LOCALSERVICE account need to be explicited with Generic Read permission. To do this you need CACLS. The syntax is cacls c:\windows\assembly /E /T /G "NT AUTHORITY\LOCALSERVICE":R From this moment ahead the Net.Tcp services stays loaded and of course Snapdrive too...

DS14MK2 and DS14MK4 shelves on same chain?
by Steve Losen 24 Jun '10

24 Jun '10

Hello Toasters, We had a downtime on a FAS6040 clustered pair to add Ethernet cards and add two new shelves of FC disks. I had to rearrange the cabling of the shelf chains because the new shelves could not be installed next to the "tail" shelves on the chains. The 6040s would not boot up because the aggr containing the root volume was incomplete. The shelf lights indicated a problem with the chains I had worked on. While inspecting my cabling, I noticed (for the first time) that the new shelves are ESH4 while the old selves are all ESH2. I also noticed that the ESH4 shelves are set to 4Gbit speed while the ESH2s are 2Gbit. Not knowing if I can mix ESH2 and ESH4, I disconnected the new shelves in such a way that they can be "hot added" later to the tails of the chains. Then the filers booted up fine. Question: Can I hot add the ESH4 shelves to the ESH2 chains if I set the speed to 2Gbit? Or must ESH4 shelves be on a separate chain? All disks are FC, I am not trying to mix SATA and FC shelves.

Several questions about ONTAP 8.0 and DS4243 shelves
by Simon Vallet 15 Jun '10

15 Jun '10

Hi, we recently acquired two filers (3140) with DS4243 shelves, and upgraded them to ONTAP 8.0. I know that this is a GA release, but I did notice some glitches (which are perfectly understandable), and have some questions for the people here who understand this better than me : - installing the 8.0 doc yields a "Documentation for Data ONTAPTM 8.0 is installed, but is out-of-date." message ; - I couldn't find any firmware updates for the DS4243 shelves on NOW -- is this normal? ; - we configured the e0M interface (and I think that it is a great idea), but I couldn't find a way to configure the filer to exclusively be administrated through e0M (i.e. the embedded SSH server now answers on both interfaces) ; - since we migrated from a 7.x release, our root volumes are on 32-bit aggregates -- is there a way to have the root volume on a 64-bit aggregate (and if not, what is the technical reason for it) ? Do some of you have encountered the same questions ?

FAS270 reporting interrupts -- fcadmin fcal_stats
by Willeke, Jochen 08 Jun '10

08 Jun '10

Hello, last weekend we had a serious problem on one of our FAS270, which lost the connection to all it's disks on channel 0b which is the internal one. Today I checked some things and found one counter rising, which is in contrast to out other filers (other FAS270 as well). The counter is adap_spurious_interrupt_cnt and it is reported when running "fcadmin fcal_stats". Sadly there is no documentation within the man-page nor on NOW about this special counter. Anybody got background-information about this numbers? Ever come across a similar issue?

Storevault to FAS snapmirror
by Glenn Dekhayser 07 Jun '10

07 Jun '10

Storevaults max out at OnTAP 7.2.1.... if I upgrade my FAS to 7.3.3, I know snapmirroring TO the FAS should still work...but what about re-sync, and/or reversing for DR failback? Am I stuck with 7.2.7 on FAS?

Moving dual attached disk loops from one adapter to another -- HOT ??
by Paul Letta 04 Jun '10

04 Jun '10

Hello, I've got 2 disk loops, both are dual attached. I've got 2 unused, dual port FC cards in slots 3 and 4. The cards/slots are listed as good for disks on the hardware guide. This is for a FAS3040, running 7.2.6.1. Loop 1 is attached to port 0a and 0c. Loop 2 is attached to port 0b and 0d. Can I do the following hot with no down time? 1) Unplug loop1 from 0a and plug it into 3a 2) Unplug loop1 from 0c and plug it into 4a 3) Unplug loop 2 from 0b and plug it into 3b 4) Unplug loop 2 from 0d and plug it into 4b I would wait after each step and verify that the disks are visible via both adapters with a sysconfig -a before moving on to the next step. I did open a support case with the exact text above. But all I got was a very non-technical answer: In rare cases it can be done... but it always has potential for problems. I will say :”NO” to your question, It is not a good idea to do it “HOT”. It would be better to schedule a time when you can have a maintenance window (there will be downtime). I can wait for an off peak time to try this. But I would rather not take the filer down to do it cold if there is a chance I can do it hot. Thanks, Paul

Moving dual attached disk loops from one adapter to another -- HOT ??
by Paul Letta 04 Jun '10

Thanks for all the public/private replies on this subject. I've heard enough that I will not attempt it. I've also heard enough that my reasoning for wanting to do it is premature and I need to find out why the expansion cards are not negotiating the FC link with the tape drive. Thanks again ! Paul

Shelf replacement on clustered pair
by Steve Losen 01 Jun '10

01 Jun '10

Hello toasters, We need to replace a disk shelf on a FAS3050 clustered pair and I was wondering if I could shut down just the filer that owns the shelf and leave the partner up, even though the partner is connected to the shelf. We had a fan fault on a PSU, replaced it, and later on the fan fault came back. Replaced it again and the same thing happened, so now we must replace the shelf. It is in the middle of a shelf chain and I must disconnect it and physically remove it from the cabinet. On the FAS3050 disk ownership is hardware assigned. Filer "A" owns all of the shelves and disks on its 0a FC adapter and the bad shelf is on this chain. The partner filer "B" is also connected to these shelves using its 0b FC adapter and the ESH2 "B" modules on the shelves. I am wondering if I can leave filer "B" up. I was thinking along these lines: cf disable shut down filer "A" power off bad shelf, disconnect, and remove install replacement shelf, move disks, PSUs and ESH2 modules from old shelf to replacement shelf. set shelf id connect and power on wait for shelf to boot and disks to spin up boot filer "A" cf enable I am sure that filer "B" will be unhappy because its 0b loop will be broken, but I hope it will stay up because all of the disks that B owns will remain available. Only partner disks owned by "A" will disappear. Will filer "B" return to normal when its 0b loop is reconnected? We are running ONTAP 7.3.1.1 I know it is safer to shut down both filers, but the resulting downtime would be more than twice as disruptive.

Have you tried a reallocate measure? What does a statit look like during the xfer? Did it ever run properly?

If throttle is set lower, then the lower value is the transfer speed. It was orginally diagnosed going over the network, but snapmirror from one volume to another on the same head is also slow. Vol copy and NFS writes to volumes in the same aggregate are ten times faster. Also, snapmirror on the partner in the FMC is fast. The aggr has 84 15k RPM disks, raid size is 21, disks are 300 GB.
