RE: Crossroads Problems
by Paul Caron 04 Nov '02

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

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.

We have tried firmware versions 4.03.16, 4.03.17, and 4.19 on the Crossroads 10000. The problem we are experiencing is that the devices on our filers which represent the SAN attached tape drives (shown by sysconfig -t) get randomly recreated every time the Crossroads reboots. Since we can't guarantee which devices will get assigned to which tape drive LUN, they often do not match those configured in the Commvault Galaxy backup software. The resulting mismatch causes many backup problems. It appears as though the Crossroads is not presenting the tape drives available on the ATL P7000 in the same order every time it reboots. We have read through the information available at http://www.netapp.com/osn/info/config.html#fcsan. This site shows support for the Brocade 3800. Although they do not call out support for the Crossroads 10000 specifically, they do show a wide range of options using various SCSI-FIBER bridges with a variety of libraries. The StorageTek library they show uses a Crossroads 42xx series switch. Has anyone else run into this situation? Is there any way of compensating for this on the Netapp filers? I realize that it would be better if the Crossroads would present the tape drive LUNs in the same order every time, but that doesn't appear to be configurable. It would help if we could permanently assign the devices to the tape drive LUNs on the filers. BTW, we have received suggestions regarding using the Netapp "storage alias" and "storage unalias" commands. However, since the Galaxy backup software relies on the actual device names (i.e. rst0l, nrst0l, urst0l, etc.) this hasn't helped us so far.

RE: My F820 is slow ....

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.

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 ....
