Moving disk shelfs between filers
by Magnar Stav Johanssen 19 Mar '03

19 Mar '03

Hi! I've got one F630 with 2 disk shelfs, 14 disks and its running OnTAP 5.3.7R3 and one F760 with 4 disk shelfs, 17 disks and its running OnTAP 6.2R2. The F630 needs more diskspace and no extra disk slots, so I've like to move one of the diskshelfs from the F760 to the F630 and add some spare disk to it. The diskshelf, which I planed to move, has 3 or 4 disks connected to it, so I must move disks internally on the F760. How do I do this with as little downtime as possible? Anybody that would like to share their experience with me? Thanks, Magnar

Dylan, This was just about the jist of my reply to Brian. We do have several NIC's in the Filer as of yet unused which could be routed to the DMZ. But it does open an entire IP stack to the DMZ whereas opening just the NFS ports through a hole in the Firewall exposes just the NFS port... -Bob At 07:26 PM 3/19/2003 +0000, Dylan Northrup wrote: >On Wed, 19 Mar 2003, Brian Long wrote: > >:=The filer should live on your DMZ :) No holes through firewalls to >:=worry about.

WWW over NFS
by Robert Borowicz 19 Mar '03

19 Mar '03

Has anybody located their root website on a filer and mounted it via NFS to their webserver? I don't believe it would need "root=" permissions. I'm considering this possibility but am curious towards the Security considerations. IE: We'd have to open the NFS port through out Firewall to the DMZ to allow the NFS mount. How secure is the NFS port in OnTAP? Thanks -Bob

RE: Moving files but not .snapshots?

No..it uses the builtin loopback/localhost IP pipe. Im not sure if theyve improved it, but IP performance over that used to be abysmal compared to GigE. -----Original Message----- From: Jeffrey.Burton(a)abbott.com [mailto:Jeffrey.Burton@abbott.com] Sent: Thursday, March 13, 2003 3:39 PM To: Art Hebert Cc: Jim Davis; toasters(a)mathworks.com Subject: RE: Moving files but not .snapshots? I don't know if the network card is in the path of an internal copy, but I'm fairly certain it does not. I copied 400M internally on my F880C in just under 2 minutes. I'm sure it depends heavily on the amount of fragmentation on the source's file system (my wafl scan measure_layout was 1.13, which is almost perfect). For some reason I can't find the ndmp throttle (to limit the CPU usage of ndmpcopy), I'm guessing that option does not exist, too bad.

See your respective Data ONTAP Data Protection Guide for more details: http://now.netapp.com/NOW/knowledge/docs/ontap/ontap_index.shtml Complete the following steps: 1. Obtain a current version of ndmpcopy from http://www.ndmp.org. 2. Install ndmpcopy on a host that has network access to the source and destination filers. 3. On both filers, enable NDMPD: a. Enter ndmpd on b. To confirm NDMP is running, enter ndmpd status. 4. Establish a "trust" relationship between the client and filer. a. Enter the hostname or interface name , i.e. , of the client and the destination filer in the source filer's /etc/hosts.equiv file. See the hosts.equiv manual page for additional options. 5. Execute the ndmpcopy on the client. The general syntax is ndmpcopy source destination Refer to ndmpcopy documentation for additional options.

You can use ndmpcopy from the filerhead CLI, granted you have a new enough DOT version. This creates a snapshot then copy's all the data and ACL's from source to target. First make sure that the ndmp option is turned on: ndmpd.enable on Then below will work: ndmpcopy /vol/sourcevol /vol/destvol You can copy at any level, not just the vol level. If the source and dest's vols are on a seperate filer just preceed the dir with "filename:" so "ndmpcopy sourcefiler:/vol/sourcevol destfiler:/vol/destvol". After the copy you can remove the temp file created at the destination end which is used for incremental updates (I forgot the name but it will be a huge file with an obviously generated name). Man page and NOW has good ndmp info.

Rancho HVD-LVD converter
by Todd Leuffgen 18 Mar '03

18 Mar '03

We have recently purchased a LVD SDLT 320 tape drive that we were hoping could plug directly into our F720 Filer. Problem is that filer has a HVD SCSI connection on the back of it and no ability to add a LVD SCSI card to it (at least that is what Netapp Support says). So I was wondering if anyone out there has tried a Rancho LVD to HVD SCSI converter in this type of application and if so what were the results. Thanks in advance, Todd Leuffgen

Resize existing volume
by Patrick Lee 14 Mar '03

14 Mar '03

I have a Filer 720. Is there any way to resize an existing volume short of re-creating it? Originally the volume started with all 18 GB drives. Overtime, as disks failed, they were replaced with 36 GB drives. So now we have some 36 GB drives that are only half used.

RE: mixing BCS and ZCS in the same volume
by Michael Schipp 14 Mar '03

14 Mar '03

Hello Steve, From the NOW site. Solution ID: ntapcs753 Title: Frequently asked questions on Zoned and Block Checksums - NetApp Filer In short is says that you can mix them but BCS will not be able to act as a spare (in you case you need an ZCS as a spare or will suffer degraded mode if a drive fails. Q. Can I add a BCS disk to an existing volume group which is currently using zoned checksums? A. Yes, they can all be added but cannot all be used as spares. With the BCS checksum format, 18 GB and 72 GB drives, can be added to a current ZCS volume as a spare in a ZCS or BCS raid group. However a 36 GB BCS drive cannot be used as a spare for a 36 GB ZCS dirve. Note also, that no Zoned Checksum disk can be used as a replacement for a BCS checksum formatted disk. Note the following exception: Q. Are the FC9 and DS14 34 GB disks identical in size and block capacity A. The 36 GB BCS formatted disk CANNOT be used as a replacement spare disk for the 36 GB Zoned Checksum disk because the 36 GB BCS disk right sizes to 34 GB and the 36 GB Zoned Checksum disk right sizes to 34.5 GB, and, therefore, does not have the same storage capacity. Q. Will I still get the performance boost from the BCS disk when it is part of a ZCS volume? A. No. Checksums are not stored in the extra 64 bits of the BCS (520B/sector) disk blocks; therefore, the volume still uses either ZCS or, for pre-Data ONTAP 6.0, no checksums at all. Q. Can a volume have more than one checksum style? A. The checksum style applies to the entire volume. You cannot have a volume with both checksum styles.
