Installation

Promise VTrak monitoring

In case of usage of Virtual Appliance

Use local account lpar2rrd for hosting of STOR2RRD on the virtual appliance
Use /home/stor2rrd/stor2rrd as the product home

The product obtains all data from Promise VTrak SNMP interface.

Install Prerequisites (skip that in case of Virtual Appliance)

AIX
Download Net-SNMP packages and install them.
Do not use the latest packages on AIX, it does not work, use net-snmp-5.6.2.1-1!
```
# umask 0022
# rpm -Uvh net-snmp-5.6.2.1-1 net-snmp-utils-5.6.2.1-1 net-snmp-perl-5.6.2.1-1
```
Make sure
- you use PERL=/opt/freeware/bin/perl in etc/stor2rrd.cfg
- PERL5LIB in etc/stor2rrd.cfg contains /opt/freeware/lib/perl5/vendor_perl/5.8.8/ppc-thread-multi path

Linux

# umask 0022
# yum install net-snmp
# yum install net-snmp-utils
# yum install net-snmp-perl

Note you might need to allow optional repositories on RHEL to yum can find it

# subscription-manager repos --list
...
# subscription-manager repos --enable rhel-7-server-optional-rpms

Use rhel-7-for-power-le-optional-rpms for Linux on Power etc ...

Linux Debian/Ubuntu
```
% umask 0022
% apt-get install snmp libsnmp-perl snmp-mibs-downloader
```
Assure that this line is commented out in /etc/snmp/snmp.conf
```
#mibs :
```
If apt-get does not find snmp-mibs-downloader package then enable contrib and non-free repositories.

Allow network access

Allow access from the STOR2RRD host to the Promise VTrak storage on port 161 UDP .
Test if port is open:

$ perl /home/stor2rrd/stor2rrd/bin/conntest_udp.pl 192.168.1.1 161
  Connection to "192.168.1.1" on port "161" is ok

Storage SNMP configuration : Enable SNMP

Login to the Promise WebPAM as a user account that has with Privilege level rights set as “Super”.
Select the “Administration” tab
Select the “Services” options from the right-side pannel:
Select “SNMP” and then select “Settings”:
Set the following:
Then select “Add” and it will then be displayed in the Trap Sinks list on the right-side box outlined in red

STOR2RRD storage configuration

Assure you have enough of disk space on the filesystem where is STOR2RRD installed
Roughly you might count 2 - 30 GB per a storage (it depends on number of volumes, 30GB for 5000 volumes)
```
$ df -g /home   # AIX
$ df -h /home   # Linux
```

Schedule to run storage agent from stor2rrd crontab (lpar2rrd on Virtual Appliance, it might already exist there)

$ crontab -l | grep load_vtrakperf.sh
$

Add if it does not exist as above

$ crontab -e

# Promise Technology Vtrak
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/load_vtrakperf.sh > /home/stor2rrd/stor2rrd/load_vtrakperf.out 2>&1

Assure there is already an entry with the UI creation running once an hour in crontab

$ crontab -e

# STOR2RRD UI (just ONE entry of load.sh must be there)
5 * * * * /home/stor2rrd/stor2rrd/load.sh > /home/stor2rrd/stor2rrd/load.out 2>&1

Let run the storage agent for 15 - 20 minutes to get data, then:
```
$ cd /home/stor2rrd/stor2rrd
$ ./load.sh
```
