Create Storage System Users


IBM SVC preparation

System preparation steps

For the communication of the BVQ SVC Scanner with the SVC CLI a user account on each SVC is mandatory, which should be at least member of the group 'Monitor'.


Create a BVQ user on the system

 expand...

With SVC CLI:

SVC CLI
svctask mkuser -name bvq -usergrp Monitor -password P@ssw0rd

For code level lower than 8.4 use:

SVC CLI
svctask mkuser -name bvq -usergrp Administrator -password P@ssw0rd


Check NTP, time and time zone

 expand...

Please check if an NTP server is configured: we strongly recommend to use an NTP server to synchronize the time of all systems (SVC Nodes, Windows):

SVC CLI
svcinfo lssystem | grep 'ntp_IP_address'


Set your NTP Server: Synchronize your SVC cluster with a specific NTP server:

SVC CLI
svctask chcluster -ntpip <IP address of NTP Server>


Adjust SVC cluster time zone: Set the time zone of your SVC cluster with:

SVC CLI
svctask settimezone -timezone 360


Show SVC clock settings: Check the current time setting on your SVC:

SVC CLI
svqueryclock

Check performance statistics interval

 expand...

The SVC performance statistics are generated regularly (in intervals) by the SVC and picked up by the BVQ SVC Scanner. BVQ supports all intervals possible in the SVC (1min to 60min). We recommend to set the time interval to 1 minute.


Check statistics status and frequency: Use this command to see if and how often your system collects statistics:

SVC CLI
svcinfo lssystem | while read key value; do [[ "$key" =~ ^(statistics_status|statistics_frequency)$ ]]&& echo "$key $value"; done


Enable statistics collection: Activate collection of system statistics:

SVC CLI
statistics_status on


Set statistics collection frequency: Define how frequently the system collects statistics:

SVC CLI
statistics_frequency 1


Start statistics collection: Begin collecting system statistics at your defined frequency:

SVC CLI
svctask startstats -interval 1


Clear I/O statistics dumps: Clean old I/O statistics data from all nodes in the SVC with this command:

SVC CLI
svcinfo lsnode -nohdr | while read id rest ; do svctask cleardumps -prefix /dumps/iostats $id ; done





Netapp preparation

A user is required for the operation of the BVQ Scanner, which should at least have readonly Role permissions on the ONTAP Cluster.

Please create this user before the configuration of the BVQ Scanner.

We recommend the name: bvq



Ontap CLI
sec login create -user-or-group-name bvq -application http -authentication-method password -role readonly

sec login create -user-or-group-name bvq -application ontapi -authentication-method password -role readonly





Dell EMC Unity preparation

A user is required for the operation of the BVQ Scanner, who should at least have Operator Role permissions.

(warning) Please create this user at your Unity System before the configuration of the BVQ Scanner. We recommend to name the user: bvq

Gather information for BVQ Scanner configuration

BVQ scanners need the following information to be configured for each Dell EMC Unity System:

  • Cluster IP address or hostname
  • Cluster user ID and password of the bvq user
  • No labels
