Installation

Dot Hill/Seagate AssuredSAN 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 uses SMI-S and WBI API interfaces natively provided by the Dot Hill storage.

Storage connectivity

Allow access from the STOR2RRD host to the storage on ports 80 (WBI) and 5988 (SMI-S).
If you use https and secure SMI-S then test ports 443 and 5989 instead.
If you use storage cmd line configuration like in examples below (you can use the storage UI instead) then port 22 (ssh) must be open.
```
$ perl /home/stor2rrd/stor2rrd/bin/conntest.pl 192.168.1.1 443
  Connection to "192.168.1.1" on port "443" is ok
$ perl /home/stor2rrd/stor2rrd/bin/conntest.pl 192.168.1.1 5989
  Connection to "192.168.1.1" on port "5989" is ok
```

Make sure that secure SMI-S (port 5989) and WBI HTTPS (port 443) protocols are enabled on the storage

CMD line:

$ ssh -l manage <storage_hostname>
# show protocols
  Service and Security Protocols
  ------------------------------
  Web Browser Interface (HTTP): Enabled
  Secure Web Browser Interface (HTTPS): Enabled
  Command Line Interface (Telnet): Disabled
  Secure Command Line Interface (SSH): Enabled
  Storage Management Initiative Specification (SMI-S): Enabled
  Unsecure Storage Management Initiative Specification (SMI-S 5988): Disabled
  ...

If secure SMI-S or WBI HTTPS are not enabled:

# set protocols smis enabled
# set protocols https enabled

Create user stor2rrd on the storage with monitor and standard roles, allow SMI-S and WBI.
- CMD line method:
  Adjust password to your preferred one from used Test1234.
```
$ ssh -l manage <storage_hostname>
# create user interfaces smis,wbi locale English password Test1234 roles monitor,standard stor2rrd
```
- UI:
Note newer firmwares might require role "standard" for WBI access.

Install prerequisites

Skip that in case of Virtual Appliance

Linux:
Install sblim-wbemcli package:

# yum list |grep sblim-wbemcli
  sblim-wbemcli.x86_64                       1.6.2-9.el7                 base
# yum install sblim-wbemcli     # RedHat
# apt-get install sblim-wbemcli # Debian based (Ubuntu etc)
# /usr/bin/wbemcli -noverify -nl ei https://<storage_hostname>:5988/root/dsh:cim_computersystem
  *
  * ./wbemcli: Http Exception: Username/password required.
  *

If you prefere to use https on port 5989 then you must use wbemcli with this patch 0002742
Download the package from:

wbemcli-1.6.3 x86_64 for Redhat 6
wbemcli-1.6.3 x86_64 for Redhat 7
wbemcli-1.6.3 for other Linuxes: ➡ Select your OS in the header ➡ "Grab binary packages directly"
wbemcli_x86_64.gz as general Linux binary, gunzip and replace /usr/bin/wbemcli by this

Test the package:

# rpm -q sblim-wbemcli
  sblim-wbemcli-1.6.3-31.1.x86_64
# /usr/bin/wbemcli -v
  * wbemcli Version 1.6.3
# /usr/bin/wbemcli -noverify -nl ei http://<storage_hostname>:5988/root/dsh:cim_computersystem
  *
  * ./wbemcli: Http Exception: Username/password required.
  *

AIX:
Download and install

# rpm -Uvh libffi-3.1-1.aix5.1.ppc.rpm --nodeps
# rpm -Uvh libiconv-1.14-2.aix5.1.ppc.rpm --nodeps
# rpm -Uvh libidn-1.29-1.aix5.1.ppc.rpm --nodeps

STOR2RRD storage configuration

All actions below under stor2rrd user (lpar2rrd on Virtual Appliance)

Add storage into configuration from the UI:
Settings icon ➡ Storage ➡ New ➡ Vendor:device ➡ Dot Hill AssuredSAN

If you set https in above storage properties then this must be enabled on the storage:

$ ssh -l manage 
# show protocols
  ...
  Secure Web Browser Interface (HTTPS): Enabled
  Storage Management Initiative Specification (SMI-S): Enabled
  ...

If you use http then this:

  Web Browser Interface (HTTP): Enabled
  Unsecure Storage Management Initiative Specification (SMI-S 5988): Enabled

Do not use shell special characters like @#!?|$*[]\{}`"'& in the password, use rather ;:.+- instead.
Make sure 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
```
Test storage connectivity, either from the UI or from the command line:
```
$ cd /home/stor2rrd/stor2rrd
$ ./bin/config_check.sh 
  =====================
  STORAGE: DotHill-alias01 : DOTHILL
  =====================
  connection ok
```
If you use HTTPS and do not have installed Perl SSL support then you get an error:
"Missing LWP::Protocol::https", "Connection reset by peer" or "500 SSL negotiation failed"
Follow this or switch to HTTP on the storage line in etc/storage-list.cfg.

Newer storage firmware releases (GL225R003) might require higher user role for SMI-S access.
Try to use "manage" role if you get this error:
```
*
* /usr/bin/wbemcli: Http Exception: Invalid username/password.
*
```

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

$ crontab -l | grep load_dothillperf.sh
$

Add if it does not exist as above

$ crontab -e

# DotHill AssuredSAN and its rebrands like Lenovo S2200 or HPE MSA2000/P2000, Dell EMC PowerVault ME4 Series, Quantum StorNex
0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/load_dothillperf.sh > /home/stor2rrd/stor2rrd/load_dothillperf.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
```
Go to the web UI: http://<your web server>/stor2rrd/
Use Ctrl-F5 to refresh the web browser cache.

Troubleshooting

Assure SMI-S is working for user stor2rrd. Adjust password and storage_hostname in example below:

$ /usr/bin/wbemcli -nl -t -noverify ein 'http://stor2rrd:<password>@<storage_hostnamew>:5988/root/dsh:SMI_Controller'
  192.168.1.1:5988/root/smis:SMI_Controller.Name="208000c0ff261f53:A",CreationClassName="SMI_Controller"
  192.168.1.2:5988/root/smis:SMI_Controller.Name="208000c0ff261f53:B",CreationClassName="SMI_Controller"

When it does not work then check user rights of stor2rrd user (must have "smis"), network visibility (firewall), user/password combination.
