This
5 part posting is a very rough and ready CLI crib sheet for Clustered ONTAP.
The
version of CDOT here is 8.1.1 / 8.1.2.
12: BASIC TROUBLESHOOTING AND PERFORMANCE
After
vol0 is available, logging goes to /mroot/etc/log/mlog
EMS
logs are at /mroot/etc/log/ems*
> debug log
From
the systemshell %, to display the log files in /mroot/etc/log/mlog
% pwd
% ls -l
Checking
Cluster Health:
> cluster show
*> cluster ring
show
For
two-node clusters only:
> cluster ha show
Is
the cluster network OK?
*> cluster
ping-cluster -node clusa-02
Are
the aggregates online?
> storage
aggregate show
> storage
aggregate show -state !online
Are
any disks broken or reconstructing?
> storage disk
show -state broken
> storage disk
show -state reconstructing
Are
the volumes online?
> volume show
-state !online
Is
storage failover (SFO) happy?
> storage failover
show
> storage
failover show -instance
Are
all the ports OK?
> network port
show
Are
all the logical interfaces (LIFs) OK and home?
> net int show
> net int show
-is-home false
The
Service Process Manager (spmd):
*> system node
systemshell local
% spmctl
*> set -privilege
diagnostic
*> spm show
VLDB
and D-Blade Inconsistencies:
> debug vreport
show
> debug vreport
fix
Statistics:
> statistics show
-object?
> statistics show
-object nfs* -instance failure* -counter write* -node clusa-01
USER-GENERATED
CORE FILES
If
the clustershell is responsive:
> system reboot
-node clusa-01 -dump true
If
the node is in bad shape, from the RLM/SP:
> system core
If
the RLM/SP is not configured:
% sysctl
debug.debugger_on_panic=0
% sysctl
debug.panic=1

To

> security audit
modify -cliset on -httpset on -cliget on -httpget on
Audited
commands go to mgwd.log files:
% egrep
“console|ssh” /mroot/etc/mlog/mgwd.log*
> security login

Onboard Antivirus is disabled in 8.1.2

EXAMPLE 13.1: MOVE A VOLUME
> volume show
> volume snapshot
show -volume vs2_vol01
> vol move start
-vserver vs2 -volume vs2_vol01 -destination-aggregate aggr1_node3 -foreground
true
> vol show
-vserver vs2 -volume vs2_vol01
> vol snap show
-volume vs2_vol01
> vol move start
-vserver vs2 -destination-aggregate aggr1_node1 -volume vs2_vol01
> vol show
> job show
> job show -id
{jobid}
EXAMPLE 13.2: REPLACE AN
AGGREGATE
> stor aggr show
> volume show
-aggr n01_aggr1
> stor aggr
create -aggr n01_aggr1_new -diskcount 6
> volume move
-vserver vs2 -volume vs2* -destination-aggr n01_aggr1_new
> stor aggr show
n01_aggr1
> stor aggr
delete n01_aggr1
> stor aggr
rename -aggr n01_aggr1_new -newname n01_aggr1
EXAMPLE 13.3: USE ROLES TO
DELEGATE ADMINISTRATIVE TASKS
> net int modify
-vserver vs2 -lif vs2_lif -frewall-policy mgmt.
> cluster show
> volume show
> volume modify
-volume vs2_vol01 -comment “modified by vs2admin”
> volume show
-volume vs2_vol01 -instance
> network port
show
> network
interface show
etcetera
