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.

We use 'wafl scan reallocate' weekly to reorder our Exchange 5.5 databases. They keep growing, and are over 100GB apiece. The wafl scan reallocate helps our use of SnapManager verifications greatly. We have been known to run it in the middle of the day, but with a big performance hit (as you have seen). Haven't tried it in conjunction with SnapMirror. Just for grins, we also use 'wafl scan measure_layout' before and after the reallocate to ensure that we've accomplished something.

On Board Fiber Channel performance

I have Filers in several locations. My newest installation has a noticeable DECREASE in performance. Of all the possible factors (OS version, network hardware/software etc..) the only common denominator is that all of my previous installations have filers with two PCI Fiber Channel Cards and the filers in the new location use One PCI Fiber Channel card and one On-Board Fiber Channel adapter. Are there any known issues with using the on-board Fiber Channel adapter vs. PCI Fiber Channel adapters ??

Hi Rich, 10 Points for quick thinking, but Round Robin DNS is BAD BAD BAD - for nearly everything. Why? Because it doesn't do health checks or test responses. (just ask your own NetCache guys, Brian or Kurt or someone, about why they recommend L4-7 switches rather than RRDNS for load balancing web servers). If you have only one mailhost listed on the filer, it will only make one attempt to send the autosupport email. If that hostname is rotated via RRDNS to multiple real servers, then if one of those real servers fails 1/N autosupport emails (where N is the number of real servers) will fail to go anywhere. If that happens to be a critical message (i.e. major component failure or overheating), you don't want to be responsible for the message not getting through. Using multiple mailhosts in the list on the filer itself is much safer. regards, Alan McLachlan Senior Systems Engineer Storage Management Solutions NetAppCA#0000019, FCNE 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: Borders, Rich [mailto:Rich.Borders@netapp.com] Sent: Tuesday, 28 January 2003 5:48 AM To: 'Walter Ellinthorpe'; Chris Thompson Cc: toasters(a)mathworks.com; david.lugo(a)unitedmessaging.com Subject: RE: Can Autosupport use multiple MailHosts?

Thanks, One more Question: the only way I was able to get autosupport to work when I set these filers up was to have an entry in the /etc/hosts file looking something like this.... 192.168.1.16 SMTP-A mailhost So, to use multiple smtp hosts, would I need to have entries like.... 192.168.1.16 SMTP-A mailhost 192.168.1.17 SMTP-B mailhost 192.168.1.18 SMTP-C mailhost 192.168.1.19 SMTP-D mailhost Thanks again, --Walter Chris Thompson wrote: walter.ellinthorpe(a)unitedmessaging.com <mailto:walter.ellinthorpe@unitedmessaging.com> (Walter Ellinthorpe) writes: I have NetApp Filers from Chicago to South Carolina and I use Autosupport to keep track of the health and happiness of each one. They all have multiple SMTP servers on their local LAN. 1. Can I configure the Filers to use multiple SMTP gateways (e.g. if SMTP-A fails, try SMTP-B. If SMTP-B fails try SMTP-C... etc.)? 2. If this CAN be done, how do I configure the Filers to do this? options autosupport.mailhost SMTP-A,SMTP-B,SMTP-C The na_options(1) man page says there can be up to five hosts in the comma-separated list. I have used it successfully with three.
