NetApp - Volume / LUN Provisioning via CLI

The NetApp System Manager has some decent controls to set up a volume - once or twice.  However, if you provision a lot of storage and you want everything to be the same, here are the commands I use.

Typically, I will set this up in notepad and then just paste it into the CLI.  Just replace VOLNAME and AGGRNAME and the sizes.  This will do the following for each volume:

• Create the volume
• Turn on dedupe (SIS)
• Configure dedupe to run automatically when it is needed (20% new data written)
• Configure auto snapshot removal on
• Configure auto snapshot removal threshold to 90%
• Set the snapshot reserve to 20%
• Turn on and configure volume autosize maximum and internal
• Hide the snapshot directory
• Turn off unnecessary access time updates for LUNs.
• If you are using NFS or CIFS in a user/file share environment, you may want to leave this option off (i.e., leave access time updates on)
• Turn on reallocation based on the default schedule/interval

vol create VOLNAME -s none AGGRNAME 500g

sis on /vol/VOLNAME

sis config -s auto /vol/VOLNAME

snap autodelete VOLNAME on

snap autodelete VOLNAME target_free_space 10

snap reserve VOLNAME 20
vol autosize VOLNAME -m 750g -i 50g on
vol options VOLNAME nosnapdir true
vol options VOLNAME no_atime_update on
reallocate start -p /vol/VOLNAME

If you work in a NAS environment, export the path:

exportfs -io sec=sys,rw=NFS_SUBNET/24,root=NFS_SUBNET/24,nosuid /vol/VOLNAME

exportfs -w /etc/exports

If you want to add this volume to all VMware hosts, in PowerCLI:

connect-viserver VCENTER
Get-VMHost | New-Datastore -Nfs -Name VOLNAME -Path "/vol/VOLNAME" -NfsHost FILERIP

If you work in a block environment, create the lun.  This is for a Windows boot lun:

lun create -s 80g -t windows_2008 -o noreserve /vol/VOLNAME/INITIATOR_boot_lun

If you need to provision the block initiators, this will set it up with ALUA / MPIO and map it to the boot lun ID:

igroup create -f -t windows INITIATOR

igroup add INITIATOR 20:00:00:25:A0:00:00:0A

igroup add INITIATOR 20:00:00:25:B0:00:00:0B

igroup set INITIATOR alua yes

lun map /vol/VOLNAME/INITIATOR_boot_lun INITIATOR 0
