Right on the button. I'm not clear on why the date would have been hosed replacing a DIMM, but that appears to be exactly what happened. It got set to 9/5/05 00:00:00 GMT. Wow. I feel a little silly for not even thinking to check that. Thanks for the advice without ", moron" attached at the end. :) -bmr On 15:39 Thu 20 Sep , Dave Barr (????) wrote: > Check the time (clock) on your filers.

snapmirror status / lag
by Brett Rabe 20 Sep '07

20 Sep '07

Howdy. Trivial question for y'all. I have two FAS3040 heads (-01 and -02) in an HA configuration. I have one FAS3040 head (-03) to which both of these are mirroring their data (every 5 minutes). The following is the status output on the backup toaster: mpls-toaster-03> snapmirror status Snapmirror is on. Source Destination State Lag Status mpls-toaster-01-priv:vol1 mpls-toaster-03:vol1 Snapmirrored 00:04:28 Idle mpls-toaster-02-priv:vol1 mpls-toaster-03:vol2 Snapmirrored 17895:54:16 Idle It all works just fine. I'm curious about the Lag time. What exactly does that mean? Why is it "17895:54:16"? It appeared that way after I did a failover of -02 (to -01) for the purposes of replacing a DIMM. Brought it back, did the giveback, and everything is working fine. The mirroring still seems to be working just great ... this is more of a curiosity question than anything, I guess. -bmr

ESX FC Give & Take
by Carl Howell 20 Sep '07

20 Sep '07

I'm troubleshooting an issue we're having with three ESX 3.01 hosts connected to a FAS3050c via Fibre Channel. After a takeover of the filer node that has active VM/LUN's running on it, the following appears in the /var/log/vmkernel file of the ESX host that owns the active VM's: Device vmhba2:0:2 has disappeared but is currently in use and could not be removed. Device vmhba2:0:3 has disappeared but is currently in use and could not be removed. On the other two ESX hosts, this appears in the /var/log/vmkernel file: Device vmhba2:0:2 has disappeared and has been removed. Device vmhba2:0:3 has disappeared and has been removed. Now, the VM's survive the takeover and are still up and running, but if I attempt a giveback, all three hosts lose access to these LUN's and the VM's go down. It appears to me that the ESX host that owns the active VM's has a SCSI reservation to these LUN's and a takeover is not enough to cause it to reset and remove that reservation(even though the paths failover properly). This type of behavior is mentioned in http://www.vmware.com/community/thread.jspa?messageID=752442. All of the timeout values have been verified etc. . . Thanks in advance for the help, --Carl

Reconnect to tape drive
by Bryano 19 Sep '07

19 Sep '07

Hi, We had a power failure the other day (dont ask...!) and as a result it looks as though our filer was brought back up before the tape library was started. One of the drives in the library is directly connected to the filer however it is not showing as being available, when I run a sysconfig -t no tape drive is shown. How can I get the filer to see the tape drive without rebooting it again?? Thanks -- View this message in context: http://www.nabble.com/Reconnect-to-tape-drive-tf4480451.html#a12775717 Sent from the Network Appliance - Toasters mailing list archive at Nabble.com.

Connect to filer via CIFS from MacOS9/Dave
by Josef Radinger 18 Sep '07

18 Sep '07

Hello, We again have troubles connecting to a filer. Connecting via Windows XP,... works great, but some Clients are old MacOS9 systems, which cannot get updated as they hold software for which no OSX version exists (or it is to expensive). We can connect with the help of DAVE http://www.thursby.com/products/dave.html (Software which enables OS9 to connect to windows/samba,...). If we try to copy folders with files, the folders get created, but the data (the actual files) is not copied. The other way (copying from the filer to the Mac) is the same. If we try this with a samba-system everything is ok. Support from DAVE tells us that they had problems with ontap 6 and macos9, but he was not too sure about this as his tests were a long time ago. They tell us, that from there side everything seems to be ok and that it is very unlikely that we could get an updated version of DAVE for OS9. Does someone have the same problem and maybe a solution? ps.: DAVE under OSX works as expected. -- MfG Josef Radinger it-services Medizinische Universitaet Innsbruck

Re: DFM 3.6 Fails to Start
by Raj Patel 15 Sep '07

15 Sep '07

>I agree with Rohit, dfm should be the only application installed. I guess I'll go down this path - maybe stick it in a VM. However it doesn't strike me as a particularly efficient solution. We're trying to consolidate monitoring not spread it out. Is there a application compatibility list for DFM ? Can I install AV software at least ? How minimalist does the OS install need to be ? Does it play nice with Microsoft MOM ? Or does anyone use the 3rd party NetApp MOM monitoring pack ? Thanks again for the comments. Cheers, Raj.
