RE: what are the columns in `snap list` ?
by Steve Evans 08 Nov '02

08 Nov '02

I assume you have date and name covered. %/used is the percentage of space the snapshot takes based on the amount of data. %/total is the percentage of space the snapshot takes based on total disk size. So let's say hourly.0 is using 100mb, you have 500mb of data, and your disk is 1000mb. %/used would be 20% (100mb/500mb) and %/total would be 10% (100mb/1000mb). The number on the left not in parentheses is the percentage of that snapshot and all the snapshots newer than it. The number in parentheses is the percentage of that snapshot only. So the number in parentheses could be all over the place. The number not in parentheses will slowly climb. You probably can't find it in the manual because it is in the Data Protection Guide, not the big sucker.

SNMP gathering of per-client stats
by Dylan Northrup 08 Nov '02

08 Nov '02

I notice in the Netapp MIB v1.2 there's a pclTable and pclEntry that look like they'll provide reports of per-client NFS statistics. I seem to recall that you can get per-client stats on the command line, but you have to turn on statistics gathering with statit -b, then turn off stat gathering with statit -enc. Can you just turn on stats gathering and poll via SNMP at any time or do you have to stop gathering stats before you can poll them? If so, what kind of performance impact does that have on the filer? Thanks in advance for any info you might have. -- Dylan Northrup northrup(a)loudcloud.com Unix System Administrator EDS Automated Operations

Root/Boot Disk(Volume?) Safety
by devnull＠adc.idt.com 08 Nov '02

08 Nov '02

Dear Toasters, I have 2 filers, a F810 and a F740. We also have some Sun servers that do NIS, sendmail, web server etc. To protect from root/boot disk failures on my Sun, i either use rsync to copy the root disk to another machine with the same hardware architecture or mirror the disk to a "backup" disk on the same machine. I have 2 volumes on my F810 vol0(which has 2 disks) and vol1(11 disks) on a DS-14 shelf. I am trying to protect myself from the situation where i lose both my vol0 disks, which will mean that my filer will no longer know anything about itself and i cant really "connect" from my backup server to the netapp to recover everything. If i lose 2 disks on vol1, i will lose all data, but i can slap 2 new disks on the filer and still recover all data from my backups. Any recommendations, thoughts on the same ? I use Legato for backup and do my backups over NFS, by mounting the volumes to my backup server. /dev/null devnull(a)adc.idt.com

RE: netapp not writing disks to /etc/.broken_disks when they fail
by Watanabe, Steve 07 Nov '02

07 Nov '02

I'm pretty sure /etc/.broken_disks was first in the 6.0 release. It is informational and not used to re-fail disks on boot. In releases prior to 6.2 Data ONTAP attempted to write "broken" onto disks that were failed. It doesn't make a lot of sense to try to write to a disk that is broken. And so... Starting with the 6.2 release the fact that a disk has been failed is kept in the Failed Disk Registry (FDR) and Data ONTAP no longer tries to write to these disks. The FDR is kept outside of the filesystem on a subset of the disks in the system. -Steve > -----Original Message----- > From: Jenner, April [mailto:April.Jenner@netapp.com] > Sent: Thursday, November 07, 2002 12:30 PM > To: 'Daniel Finn'; 'toasters(a)mathworks.com' > Subject: RE: netapp not writing disks to /etc/.broken_disks when they > fail > > > Really? > > I'm using 6.2.1R2 and have never been able to see > /etc/.broken_disks > > I'm using an F740 and an F840 > > > -----Original Message----- > > From: Daniel Finn [mailto:DFinn@studentadvantage.com] > > Sent: Thursday, November 07, 2002 9:22 AM > > To: 'toasters(a)mathworks.com' > > Subject: netapp not writing disks to /etc/.broken_disks > when they fail > > > > > > It's an F740 running ONTAP 5.3.5R2.

netapp not writing disks to /etc/.broken_disks when they fail
by Daniel Finn 07 Nov '02

07 Nov '02

It's an F740 running ONTAP 5.3.5R2. Is this normal? All the rest of the netapps we have write to /etc/.broken_disks when a disk fails but they are also running a more up to date version of ONTAP. Is it because of the older version?

I saw someone mention they had some old equipment (F630) on here. I was wondering if anyone was interested in picking up some "spare parts" for a NetApp. We have an F540 with two sets of diff SCSI 4GB shelves and two sets of diff SCSI 9GB shelves plus lots of spares (minus the motherboard.)

This was a problem that I encountered early in ONTAP 6.0.x (and 6.1.x to?) although sporadic, often enough to write a perl script to reset the tape aliases a few times a week.

The Filer actually sees the real LUN value, but you may assign an alias, such as st01 st02 ... the device names rst02,nrst02,urst02 etc gives the device functionality.

RE: Storagetek l80
by James Beal 06 Nov '02

Hello, We just became the proud owners of an L80. Its a bit of a big beast, and has baffled me a bit! I was wondering if anyone out there has one of these attached directly to the netapp, and also attached to a backup server such as an E250? During the selection process the company we engaged told me that each drive could be connected directly to a machine via SCSI. Looking at the back of the library, I think this is do-able, as each drive has SCSI connections, but I am not sure if these are intended to be connected to the library itself, then daisy chained together, or if the drive can be attached to the filer... I am waiting on a colleague to chase the supplier, but thought I put out request to you guys too... Okay, I don't have a toaster at present but I have looked after them in the past. I do have a L80 which is a great tape library. Each of the tape drives can be connected to a different system and storage tek will say if you have LTO drives in it then each drive should really be on a separate bus for performance/reliablity issues. What software are you using to drive this, netback from veritas can handle one having a robotic with the tape drives attached to different machines, for a toaster you would need to have a NDMP license as well, the robotic being controlled by the E250.

RE: Crossroads Problems

Thanks for your responses. Here are some answers to the questions that were presented. > Have you set any values in the "Fibre Channel to SCSI mapping"/ "Mapping Table#"? We have a custom map that we're using to map the individual tape drives to Crossroad LUNs. > Do the values change after reboot? No. > What about "Display Attached SCSI Devices", does this change between reboots? No. The attached SCSI devices are always the same. ---------------------------------- The "Fibre Channel to SCSI Mapping Mode" for our Crossroads is not set to auto. We are using a custom map to make sure that each tape drive always has the same LUN. We are not using the "index" map since that one is currently being used for our Windows media agent. However, there doesn't appear to be a difference between custom maps and the "index" map other than the name of the "index" map cannot be changed. If I am mistaken, please let me know. Also, I guess I need to qualify my details a bit more. The LUNs presented by the Crossroads are fixed in that they are always refer to the same drive on the P7000. The problem is that the LUNs get assigned to different devices on the filer. For example, LUN 2 will be assigned to the rst1l, nrst1l, ..., urst1a devices after one of the Crossroads reboots. After another Crossroads reboot, LUN 3 will be assigned to those same devices on the filer. We need to preserve a consistent device mapping on the filer. Reassigning storage aliases seems to be the best workaround we've found so far. My quick hack script to do this is below (the x:xxx:xxxxxx:xxxxxx represents the WWN of the Crossroads). We're still looking for a better long term approach. Either the Crossroads needs to present the LUNs in the same order every time, or the Netapp filer needs to have a way to specify a persistent device-to-LUN mapping for FCAL attached devices. ----------------------------------------------------------------------- #!/bin/sh FILER=$1 if [ -z "$FILER" ]; then echo "usage: resetaliases <filername>" exit 1 fi /bin/rsh $FILER storage unalias -a /bin/rsh $FILER storage alias mc0 WWN[x:xxx:xxxxxx:xxxxxx] /bin/rsh $FILER storage alias st0 WWN[x:xxx:xxxxxx:xxxxxx]L1 /bin/rsh $FILER storage alias st1 WWN[x:xxx:xxxxxx:xxxxxx]L2 /bin/rsh $FILER storage alias st2 WWN[x:xxx:xxxxxx:xxxxxx]L3 /bin/rsh $FILER storage alias st3 WWN[x:xxx:xxxxxx:xxxxxx]L4 /bin/rsh $FILER storage alias st4 WWN[x:xxx:xxxxxx:xxxxxx]L5 /bin/rsh $FILER storage alias st5 WWN[x:xxx:xxxxxx:xxxxxx]L6 /bin/rsh $FILER storage alias st6 WWN[x:xxx:xxxxxx:xxxxxx]L7 /bin/rsh $FILER storage alias st7 WWN[x:xxx:xxxxxx:xxxxxx]L8 exit 0 -----------------------------------------------------------------------

RE: Crossroads Problems
by Mike Ball 01 Nov '02

01 Nov '02

Paul, It sounds like you are running the Crossroads router in "Fibre Channel to SCSI Mapping Mode" of auto. Change the mode to "Indexed" and this should fix your problem. The mapping mode determines how the targets behind the router (i.e. tape that are attached to the SCSI side of the router) are seen by Fibre Channel hosts on the network. Specifically, the various addressing modes determine how Fibre Channel LUNs are mapped to the SCSI peripherals on the router, and how that mapping can change when you reboot or reconfigure the router. You normally want to use indexed mode to ensure that particular target/luns on the SCSI side of the router are persistently presented as the same LUNs on the Fibre Channel side of the router, regardless of whether devices have been removed on the SCSI side or were turned off when the router booted.

You said you had more than one volume ?. Were the disks all added at the same time ?. That is, you have not added a disk to an existing volume?. Is the activity read or write activity or a mix ?. Can you post up a sysstat output ?. Try using 'statit' which will indicate if a specific disk is being hammered. If this is the case then it would mean that a disk was added to the volume group after vol creation and normal stripping is not in effect. -----Original Message----- From: Mike Horwath [mailto:drechsau@visi.com] Sent: Friday, 1 November 2002 10:11 To: Mike Ball Cc: 'Pawel Rogocz'; toasters(a)mathworks.com Subject: Re: My F820 is slow ....

Hey Clarence, Filer MRTG is great, we run it now even with Datafabric Manager running as well. It isn't very good for performance analysis but great for monitoring filesystem usage and particularly snapshots if you are doing any snapmirroring.

The instructions can be found at http://now.netapp.com/NOW/download/tools/filer-mrtg/. It "provides a current and historical view (the last day, week, month, and year) of statistics for network traffic, CPU load, disk usage, and NFS and CIFS operations." -- Clarence. > thanks, > > > Pawel

How many disk shelves have you got? How many FCAL's you got? Running any database devices on the filer? What size raid groups have you got? Especially for databases. Running any gigabit interfaces on Sun boxes? Was the system running fast for a long period then suddenly performance dropped or has it been gradual degradation? Does a netdiag -v report any unusual NFS or application errors? I have many more questions as I am going through something similar right now. Hopefully we can help each other.

Hi Pawel, We have an F880 (6.2.1) with about 10-20 Sun boxes connected to ours. We are experiencing the same type of slowdown and sysstat readouts. Our database volumes are running particularly slow. I am working with NetApp now to resolve this. Try the following set of commands; Go into advanced mode on the filer (telnet in) Priv set advanced *you will see a star showing advanced mode filer*> statit -b leave for a few minutes filer*>statit -enc an nfsstat -l shows a detailed usage of nfs on a per client basis This will give a detailed summary Hope it helps, Aaron -----Original Message----- From: Pawel Rogocz [mailto:pawel@rogocz.com] Sent: Friday, November 01, 2002 5:24 AM To: toasters(a)mathworks.com Subject: My F820 is slow .... I run 6.2.1 on F820 and I have bunch of Sun boxes ( around 60 ) who do NFS mounts. The filer has more than one volume and sometimes during the day the output of systat -x shows 100% disk util for a couple of minutes. 1. Is there a way to find out which volume/disk is causing bottleneck ? 2. Is there a way to find which client is causing the load to spike ? 3. Can disk util be monitored via SNMP ? I was not able to find anything in the MIB provided on NOW. thanks, Pawel --

Pawel, Have you grown your volumes lately? If so, how many disks did you add to the volumes when you grew them? I have seen customers who have volumes that are at 90%-95% and they add one or two disks to increase the disk space for the volume. What this does is creates a hot spot where any new writes going to those volumes only gets written to the 1 or two disks which were added = bad performance because WAFL is not able to stripe across all the disks in the volume.
