Solaris 2.8 NIS and DataONTAP
by Brent.Killion＠pinnaclewest.com 31 Jan '03

31 Jan '03

Toasters- Has anyone seen any difficulty in getting a F880c running 6.2.2 to bind to a NIS domain running on a Solaris 8 NIS master? We have an F880c that plays very nicely when bound to a NIS server running Solaris 2.6. We built a new NIS domain, with a new name, running on Solaris 8 but the F880c systems refuse to bind to the new domain when following the standard DataONTAP commands. We're pretty confident that the new NIS domain config isn't the problem as we have 75 other Solaris systems of the flavor of 2.6, 7, and 8 bound to it with no problems. Here is the relevant portion of the snoop output when snooping the interface on the NIS server. I see the call from the filer "filer2" to the NIS server "dvniss" but the NIS server refuses to answer it's bind request. This just repeats over and over every time the filer sends a bind request. {root}on dvniss< snoop filer2 Using device /dev/dmfe (promiscuous mode) filer2 -> dvniss NIS C DOMAIN_NONACK pwcorp filer2 -> dvniss NIS C DOMAIN_NONACK pwcorp filer2 -> dvniss NIS C DOMAIN_NONACK pwcorp Can anyone shed any light on what we may be missing? A search of now.netapp.com revealed no similar problems and Sun has validated our NIS configuration. Thanks to all, Brent Killion

RE: Problem with using ndmpcopy with a filer
by Michael Schipp 30 Jan '03

30 Jan '03

Hi Kyle, Below is the documentation from Ontap 6.3.1 - I would check you authentication {md5|text) - see below Copying data with ndmpcopy What ndmpcopy is The ndmpcopy command calls a filer-resident data migration tool that controls the transfer of file system data between filers that support NDMP v3 or v4 and the UFS dump format. The ndmpcopy command supports both full and incremental data transfers; however, incremental transfers are limited to a maximum of two levels (one full and up to two incremental). The ndmpcopy command can transfer full or partial volumes, qtrees, or directories, but cannot be used to copy individual files. ndmpcopy functions as a simple NDMP data management application (DMA) that performs data transfers by initiating a backup operation on the source filer and recovery operation on the destination filer. It establishes separate NDMP control connections with the source and destination filers, creates a single NDMP data connection between the filers, and initiates backup and recovery operations that result in the desired data transfer between the source and destination. Because ndmpcopy is an NDMP application rather than an NDMP server, it can be executed at the command line of the source filer, the destination filer, or a filer that is neither the source nor the destination of the data transfer. It is also possible to execute ndmpcopy on a single filer that is both the source and the destination of the data transfer. See the ndmpcopy examples, next, for more information on supported data transfer topologies. How to copy data using ndmpcopy To copy data within a filer or between filers using ndmpcopy, complete this step. Note The command can also be entered from a filer that is not the source or the destination. Step Action 1 Enter the following command: ndmpcopy [options][source_filer:]source_path [destination_filer:]destination_path options can be one or more of the following: -sa username:[password]--Source authorization specifies the user name and password to be used when connecting to the source filer. -da username:[password]--Destination authorization specifies the user name and password to be used when connecting to the destination filer. -st {md5|text}--Sets the source authentication type to be used when connecting to the source filer. -dt {md5|text}--Sets the destination authentication type to be used when connecting to the destination filer. By default, md5 is the authentication type used. The text authentication type exchanges the user name and password over the network in clear text. The md5 authentication type exchanges the user name and password over the network in encrypted form. -l level--Sets the dump level used for the transfer to the specified value of level. Valid values for level are 0, 1, and 2, where 0 indicates a full transfer and 1 or 2 an incremental transfer. The default level is 0. -d--Enables generation of ndmpcopy debug log messages. ndmpcopy debug log files appear in the root volume /etc/log directory. The ndmpcopy debug log file names are in the form ndmpcopy.yyyymmdd. -f -- Enables forced mode. This mode enables overwriting system files in the /etc directory on the root volume. See Example 5 for details. -h--Prints the help message. source_filer and destination_filer can be host names or IP addresses. Examples of the ndmpcopy command In these examples, network host names are used for the filers. ("myhost" is used for a local filer and "remotehost1" and "remotehost2" are used for remote filers.) If you specify host names when you use the ndmpcopy command, the filer running the ndmpcopy command should be able to resolve these names to their IP addresses. In UNIX, you can use the ping command to make sure that host name resolution works. Example 1: This command migrates data from a source path (source_path) to a different destination path (destination_path) on the same filer (myhost). myhost> ndmpcopy -sa username:password -da username:password myhost:/vol/vol0/source_path myhost:/vol/vol0/destination_path This shorter form of the command achieves the same purpose: myhost> ndmpcopy /vol/vol0/source_path /vol/vol0/destination_path Because you are running the ndmpcopy command on myhost and the source and destination filer are the same as myhost, you can omit the source and destination filer names on the ndmpcopy command line. When your ndmpcopy command is running on the same filer as the source filer or destination filer, you can also omit the -sa or -da options. Example 2: This command migrates data from a source path (source_path) to a different destination path (destination_path) on remotehost1. myhost> ndmpcopy -da username:password /vol/vol0/source_path remotehost1:/vol/vol0/destination_path The destination filer must be specified in this case, because it is a remote filer. The destination authorization is needed, but not the source authorization. Example 3: This command migrates data from a source path (source_path) on remotehost2 to a destination path (destination_path) on myhost. myhost> ndmpcopy -sa username:password -st text remotehost2:/vol/vol0/source_path /vol/vol0/destination_path The source authentication type specified by -st is text. The ndmpcopy command tool running on myhost will authenticate with the source filer using text authentication. Example 4: This command migrates data from a source path (source_path) on remotehost1 to a destination path (destination_path) on remotehost2. myhost> ndmpcopy -sa username:password -da username:password -l 1 remotehost1:/vol/vol0/source_path remotehost2:/vol/vol0/destination_path The -l 1 option is used to do a level 1 transfer. Example 5: Without the -f option, the /etc directory and its contents on the root volume of remotehost1 are protected from being overwritten with the /etc directory from myhost, preventing unintentional changing of the system characteristics after the root volume migration is completed. myhost> ndmpcopy -da username:password /vol/rootvol remotehost1:/vol/rootvol To overwrite intentionally the /etc directory during the root volume migration, use the -f flag as in the following copy. myhost> ndmpopy -da username:password -f /vol/rootvol remotehost1:/vol/rootvol -----Original Message----- From: kyle [mailto:kyle@source.intac.net] Sent: Thursday, 30 January 2003 5:29 AM To: toasters(a)mathworks.com Subject: Problem with using ndmpcopy with a filer I know that this isnt the correct forum to ask about ndmpcopy, but I do know that some use ndmpcopy with their filers.

RE: trunking questions
by Alan McLachlan 29 Jan '03

29 Jan '03

Hi Patricia, The versions of Ontap you are running only support FEC ("fast ether channel") and GEC ("gigabit ether channel") - that's really all your switch guy should need to know. The filer maintains a seperate static MAC for each interface, rotating MAC's etc is a switch feature and has nothing to do with what happens on the filer (or any other server with FEC). In the case of CIFS connections (which bind to a MAC address) for your quad 100BaseT cards this means that each connection can still only acheive a theoretical maximum of 100Mbit/sec - your trunked "400Mbit" connection is the theoretical maximum aggregate throughput for 4 or more connections. So to make the most use of the trunk you need to have many concurrent client connections. What the forum message you were looking at was getting at is that several connected clients may end up bound to the same interface based on the timing of their connections and the ARP responses they get - this is why some switches with FEC support "spoof" the target MAC's to round-robin the packets evenly across the ports (since the FEC enabled server or filer won't care about which interface it receives data on. Also the author of that comment made a good point about routing - you need a FEC enabled switch between the router and the filer trunk to prevent all packets from that router hitting the same NIC. Data OnTap 6.2 and above support 802.3ad "dynamic link aggregation". If your switch supports 802.3ad you should upgrade the filers (providing your software support is paid up!) and use that method. Note that from the filer's perspective setting up an active/active trunk on 802.3ad is identical to FEC/GEC, however the switch configuration will be different. Hope this helps. regards, Alan McLachlan Senior Systems Engineer Storage Management Solutions ASI Solutions www.asi.com.au Ph +61 2 6230 1566 Fax +61 2 6230 5343 Mobile +61 428 655644 e-mail amclachlan(a)asi.com.au -----Original Message----- From: pdunkin(a)lucent.com [mailto:pdunkin@lucent.com] Sent: Wednesday, 29 January 2003 12:48 PM To: toasters(a)mathworks.com Subject: trunking questions First, thanks again to all who responded to my questions about migration to a new switch. The next question concerns NetApp support for trunking. Our F760 has two quad Ethernet cards, and our F740 has one. Each group of four is currently trunked together, and we would like to keep them that way. The guy in charge of the new switch wants to know how NetApps support groupings: port based, address based, or round robin? This <http://forums.netapp.com/conversation.asp?tid=1&vid=9553&thd=1&cid=51> says trunking is done on a per MAC address level, but in the archives of this list I saw references to round robin and didn't know if that may also be an option. So, what should I tell the switch manager? And, if it's something that can be administered on the NetApp, what command or commands do you use, with what parameters? I think I understand the vif command, but the versions I have (Release 5.3.4R3 on the F740; Release 5.3.6R2 on the F760) don't seem to have a parameter that selects a trunking algorithm.
