FCP curiosity
by Milazzo Giacomo 06 Mar '08

06 Mar '08

Hi I've just set up a 3020C with two HBA attached to a couple of Brocade, and on these, 2 couple of HBA coming from 2 Windows host. A SAN, do you know it? J The links are the usual ones: i.e. the 1st HBA of host "A" to the upper Brocade, the 2nd to the lower and so on...the 0b of the head to the upper, the 0d to the lower and the same for other head. When I perform a scan of fcp channels (priv set advanced, don't remember now the command) from one of the two head of the 3020C I see 4 WWN of the 4 HBA of the hosts repente two times (4 real and 4 replicated) and I've already saw this times ago (the path is replicated through the cluster interconnect). But when I perform the same from the other head I can see only 4 WWN belonging to the hosts. Why? Something wrong on link of the hosts to the couple of switch? Maybe because I've not yet zoned the switches? Thanx a lot

I think VCB requires that you are running Virtual Center so you will need to deploy that.

which netapp LUN corresponds to which Windows disk ?
by Stephen C. Losen 04 Mar '08

04 Mar '08

We have a bunch of netapp LUNs of the same size mapped to a Windows box and it isn't clear how we can tell which one is which. I'm not a Windows person. The Windows admin sent me the Windows info about one of the disks and I can't see anything that would indicate which LUN it is on the netapp. Nothing appears to correspond to the LUN serial number or the igroup mapping number, etc. Is there a way to read the Windows "disk signature" with a netapp command? Or is there a Windows command to print the LUN serial number? Or what about the igroup mapping number?

RE: move data within CIFS
by Paul Keating 29 Feb '08

29 Feb '08

Even within a drive letter, if the two directories are different mounted shares, it will have to copy. for example. you have an export on your filer called /vol/vol1/home which is mounted on a PC host as E:\ You have another export on your filer called /vol/vol1/home/new which is mounted on a PC as E:\dev\ drag & drop, move, CP, robocopy or whatever you have will copy that data over the LAN via the PC, even though it's the same "drive letter".

RE: move data within CIFS

Hi, when i get this right you are moving data within on volume. e.g. /vol/project/data1/data2copy to /vol/project/data2/destination When this is on the same filer a move should proceed within seconds, as you are used to have it on a local hard disk. You can just use "Drag-and-Drop" when connected to the share with sufficient rights. Just give it a try with a testvol.

I'm not a Windows expert, but perhaps you can do it in a DOS window with "move" or "rename". Are you moving the data across qtrees? In this case, you are stuck with copy-then-delete. Of course, you can cut down on the total disk space required by moving the 6T in smaller pieces. Steve Losen scl(a)virginia.edu phone: 434-924-0640 University of Virginia ITC Unix Support

Thanks Michael, we have no NFS here, and even if we had, I would never try it out. First, I cannot imagine how NFS should work where CIFS does not while handling CIFS-data. The scond reason is, what happens to spaces, special characters, ... And third, wo should NFS handle the nested group permissions of CIFS. With Unix-schema owner/group/world the filer would calculate the permissions for the given user - and after the copy all detailed ACL-information would be lost.
