NETWORK

To check the network interface/Configuration: ifconfig -a

DISKS

To assign all disks in one go:

netapp1> disk show -n

2. Assign the disk to the filer
netapp1> disk assign switch2:44.126L155 -o netapp1
Sat Aug 7 10:17:15 BST [netapp2: diskown.changingOwner:info]: changing ownership for disk switch1:12.126L155 (S/N 6001438005DEAAE00000700005D40000) from unowned (ID -1) to netapp1 (ID 151735370)

STORAGE PORTS

To check the alias for storage ports/devices a netapp is zoned with:
netapp1> storage alias
Alias Mapping
————————————– ————————————-
mc0 WWN[5:005:07630f:0f2601]L1
mc1 WWN[5:005:07630f:0f2611]L1
st0 WWN[5:005:07630f:0f2604]
st1 WWN[5:005:07630f:0f2602]
st10 WWN[5:005:07630f:0f2613]
st11 WWN[5:005:07630f:0f2614]
st12 WWN[5:005:07630f:0f2615]
st13 WWN[5:005:07630f:0f2618]

To unalias the storage port aliases and configrue the correct desired names:
netapp1> storage alias st1 WWN[5:005:07630f:0f2601]

If you had several tape drives to be aliased, it is better to put them together in a file under /etc/, say /etc/tape_aliases.dc1. And then source this file using:
netapp1> source /etc/tape_aliases.dc1
netapp1> storage alias
Alias Mapping
————————————– ————————————-
mc0 WWN[5:005:07630f:0f2601]L1
mc1 WWN[5:005:07630f:0f2611]L1
st0 WWN[5:005:07630f:0f2604]
st1 WWN[5:005:07630f:0f2602]
st10 WWN[5:005:07630f:0f2613]

USER

To create a user and set its password:
netapp1> useradmin user add backups -g Users -c “Backup user” -m password
New password:
Retype new password:
User <backups> added.

To change the login mode (privilege/diag):
netapp1> priv set advanced
netapp1> priv set diag

VOLUMES

Create a normal flexible volume
netapp1> vol create vol1 -l en agg1 1112g

Check the size of volume
netapp1> vol size vol1

Find out which aggr a volume is created on
netapp1> vol status vol1 -v

AGGREGATES

Create aggregate
Example: 1
netapp1> aggr create agg_1 -r 17 -t raid_dp 51@137104M
-r –> so many disks in one raid group
137104M –> size of disks – get that from vol status -r
This will create an aggregate spanning 3 raid groups each containing 17 disks – if disks were not in use before (assigned to raidgroup) the aggr will be created straightaway. However if they were in use, they will need to be zeroed which will take long time.

Example: 2
In this case we have 36 disks owned by each filer. so we can create 2 aggregates with raid0 and raidgroup having 9 disks (size 874496M obtained from vol status -r)
netapp1> aggr create agg_101_fa_2 -r 9 -t raid0 18@874496M
Creation of an aggregate with 18 disks has been initiated. The disks need
to be zeroed before addition to the aggregate. The process has been initiated
and you will be notified via the system log as disks are added.
Note however, that if system reboots before the disk zeroing is complete, the
volume won’t exist.

Delete an aggregate
netapp1> aggr status
Aggr State Status Options
vol0 online raid4, trad root
aggr0 online raid_dp, aggr
netapp1> aggr offline aggr0
netapp1> aggr status
Aggr State Status Options
vol0 online raid4, trad root
aggr0 offline raid_dp, aggr lost_write_protect=off
netapp1> aggr destroy aggr0
netapp1> aggr status
Aggr State Status Options
vol0 online raid4, trad root

To set the snap reserve on aggregate
Aggregates are created by default with 5% reserve space. Generally, we don’t reserve the space on aggr instead we reserve on per volume. So, disable the snap reserve on aggrs and reduce it to 0%.
netapp1> aggr options agg_2
nosnap=off, raidtype=raid_dp, raidsize=16, ignore_inconsistent=off,
snapmirrored=off, resyncsnaptime=60, fs_size_fixed=off,
snapshot_autodelete=on, lost_write_protect=on
netapp1> aggr options agg_2 nosnap 1
netapp1> aggr options agg_2
nosnap=on, raidtype=raid_dp, raidsize=16, ignore_inconsistent=off,
snapmirrored=off, resyncsnaptime=60, fs_size_fixed=off,
snapshot_autodelete=on, lost_write_protect=on
netapp1> snap reserve -A
Volume vol0: current snapshot reserve is 20% or 156217696 k-bytes.
Aggregate agg_1: current snapshot reserve is 0% or 0 k-bytes.
Aggregate agg_2: current snapshot reserve is 5% or 546761940 k-bytes.
netapp1> snap reserve -A agg_2 0
netapp1> snap reserve -A
Volume vol0: current snapshot reserve is 20% or 156217696 k-bytes.
Aggregate agg_1: current snapshot reserve is 0% or 0 k-bytes.
Aggregate agg_2: current snapshot reserve is 0% or 0 k-bytes.

NTP

Options to be set for ntp:

netapp1> options timed.protocol ntp
netapp1> options timed.servers ntp1.domain.com,ntp2.domain.com
netapp1> options timed.sched 5m

NIS/DNS

To set up NIS

1. Set up nis options

netapp1> options nis.enable on
netapp1> options nis.domainname prod.yourdomain.com

2. Set up DNS options

logisnap233a> options dns.enable on
logisnap233a> options dns.domainname yourdomain.com

3. Edit rc file so that it looks something like as below (should have NIS/DNS related info)
netapp1> rdfile /etc/rc
vif create multi vif1 -b ip e4a e3a
vif create multi vif2 -b ip e4b e3b
vif create single vif233a vif1 vif2
ifconfig vifnetapp1 `hostname`-vifnetapp1 netmask 255.255.255.0 partner vifnetapp2
route add default 192.168.1.1 1
routed on
options dns.domainname yourdomain.com
options dns.enable on
options nis.domainname prod.domain.com
options nis.enable on
savecore
timezone Europe/London

4. Set up /etc/resolv.conf file

netapp1> rdfile /etc/resolv.conf
nameserver 192.168.1.250
nameserver 192.168.1.251
search yourdomain.com subdomain.yourdomain.com

5. Verify dns is set up correctly
netapp1> dns info

6. Verify nis is set up correctly
netapp1> nis info

AUTOSUPPORT

Options to be set for autosupport (will require a reboot to take effect)

netapp1> options autosupport.enable on
netapp1> options autosupport.from admin@domain.com
netapp1> options autosupport.mailhost mailhost.domain.com
netapp1> options autosupport.noteto admin@domain.com
netapp1> options autosupport.to autosupport@netapp.com,admin@domain.com

To generate autosupport manually:
Suppose node1/node2 are clustered node, and node2 has panicked, and taken over by node1. You are asked to generate autosupport on node2. Follow the steps below:

node1(takeover)> partner
Login to partner shell: node2
node2/node1> Mon Sep 27 11:24:13 BST [node1 (takeover): cf.partner.login:notice]: Login to partner shell: node2
node2/node1> options autosupport
autosupport.cifs.verbose off
autosupport.content complete
autosupport.doit DONT
.
.
.
node2/node1> options autosupport.doit DO

 SYSTEM

To find the WWN/System related information:
netapp1> sysconfig -av ->
shows all the information
netapp1> sysconfig -av 2 ->
shows info about FC Adapter

    Thanks for this. I found it very useful. I did not know, for instance, that you could assign spare disks to a filer other than the one you’re currently logged onto.

    I’ve bookmarked your page, and will check back often for updates. Thank you!
