## Bitpushr’s Blog ##
First time I’d come
across this blog (please more updates.) Some interesting articles:
Understanding
NFS operation types (March 2013)
Getting
started with Data ONTAP cluster-mode (October 2012)
A useful link to
the Cisco Nexus 5010 12-Node Cluster Switch config:
Extract -
converting from 8.1 7-Mode into C-Mode:
set-defaults
setenv
bootarg.init.boot_clustered true
setenv bootarg.init.usebootp
false
setenv bootarg.bsdportname e0a

vlan create Internal_VIF 20
ifgrp create lacp Vmware_VIF
ifconfig Internal_VIF 192.168.1.197 netmask 255.255.255.0 partner Internal_VIF mtusize 1500 trusted wins up

NetApp - Performance Analysis ##
From communities.netapp.com
CMD> plink.exe FILERNAME
CMD> perfstat -f FILERNAME -t 3 -i 6 -l root -S pw:password1 > CASENUMBER.FILERNAME.PERFSTAT.OUT
-t
3: This defines the delay between each scan
-i 6: How many iterations (scans) do you want to run on the filer)
From communities.netapp.com and
kris.boeckx@pidpa:
Commands to troubleshoot performance
issues:
## Start with:
priv set diag
# For detailed CPU statistics and
how to identify the cause of high CPU
sysstat -M -i 5
# Shows you the different I/O
("Disk util" is very important, and also "CPty" see Manual
Pages - sysstat )
sysstat -x 5
# Shows you the read / write /
latency's of luns
lun stats -i 5
# Shows you detailed info of every
lun (you will want to capture this in an output file)
stats show lun
# Same as lun but now for the
volumes (you will want to capture this in an output file)
stats show volume
# Shows if any reallocation jobs are
running (walf scan status shows you even more info)
reallocate status
## For even more info!
# Will start the data collection
(wait a few minutes)
statit -b
# Will stop the collection and will
give you the result.
statit -e
From NetworkAdminKB:
stats show
reallocate measure -o
/vol/fragmentedvolume/lun
reallocate status
reallocate start -f -p
/vol/volume_name/lun
man reallocate

NetApp - Volume Migrations (in 7-Mode) ##
Ways to move a volume to another
aggregate (of course, in Clustered ONTAP this is very easy):
ndmpcopy - Copy the entire volume from one location to another. Create
the new volume first.
vol copy - Similar to NDMPCOPY, but the destination volume needs to be
restricted.
snapmirror - This is nice as you can setup a
schedule and keep the updates going until you are ready to do the final copy.
host based - Use something like robocopy or
rsync to copy the data from one volume to another.
vol move (DOT 8.x) - Unless it is a snapmirror or snapvault target.

From viktorious.nl:
esxtop -b -d 10 -n 360 > esxtopresults.csv
- or -
esxtop -b -d 10 -n 360 | gzip >
esxtopresults.csv.gz
Then add as a new source in permon!

Consider if there
is a very big read or very big write that is going on…
