Free SAN and storage performance and capacity monitoring

Fujitsu ETERNUS storage installation

Back to storage installation home.

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
It is already implemented but not released yet. Expected release in STOR2RRD v2.15 Jan 2018.
Anyone willing to beta test it? Contact us at

All Fujitsu ETERNUS are supported.
NAS feature of Hybrid Storage Systems is not monitored.
The product uses ETERNUS CLI interface natively provided by the storage to get all necessary data (ssh access).

Storage connectivity

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

  • Allow access from the STOR2RRD host to the storage both MNT interfaces on port 22 through your network.
    $ perl /home/stor2rrd/stor2rrd/bin/ 22
      Connection to "" on port "22" is ok
  • Create ssh-keys on STOR2RRD host under stor2rrd user if do not exist yet.
    It should already exist on the Virtual Appliance, skip it there.
    $ ls -l ~/.ssh/
    $ ssh-keygen -t rsa -N ""
      Generating public/private rsa key pair.
      Enter file in which to save the key (/home/stor2rrd/.ssh/id_rsa):
    $ ls -l ~/.ssh/
      -rw-r--r-- 1 stor2rrd stor2rrd 382 Jun  1 12:47 /home/stor2rrd/.ssh/
  • Convert ssh-keys into IETF format.
    Storage import utility expects ssh-keys in IETF format.
    Keys in usual *.pub format will be accepted but access will not work!
    $ ssh-keygen -e -f ~/.ssh/ >
    $ ls -l
      -rw-r--r-- 1 stor2rrd stor2rrd 507 Jan  8 08:43
  • Create user stor2rrd on the storage with monitor role and authorized via ssh-key.
    System ➡ User Setting ➡ Setup User Account ➡ Add
    Fujitsu ETERNUS monitoring setup user add

  • Assure that performance monitoring collection is enabled on the storage and historical collection is set to 300 secs.
    It must be set to 300 seconds to work correctly!
    System ➡ Utility ➡ Start/Stop Perfmon ➡ Select 300 ➡ Apply

    Note: this setting is reset (disabled) after each storage reboot at least with firmware release we have tested it.
    It means that you have to enable performance monitoring and set interval after each storage reboot.

STOR2RRD storage configuration

  • Uncomment (remove the hash) example line and adjust it:
    $ vi /home/stor2rrd/stor2rrd/etc/storage-list.cfg
    # Fujitsu ETERNUS
    # Storage Alias:ETERNUS:Controller_A IP address or hostname:Controller_B IP address or hostname:storage user:VOLUME_AGG_DATA_LIM:VOLUME_AGG_IO_LIM:SAMPLE_RATE_MINS
    Above shows the storage with IP's, which will be visible in the GUI as eternus-alias01
    You can use either MNT interfaces or even RMT, it will work with all.

  • 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
  • Check storage connectivity
    $ cd /home/stor2rrd/stor2rrd
    $ ./bin/ eternus-alias01
      STORAGE: eternus-alias01 : ETERNUS  
      connection ok
  • Schedule to run storage agent from stor2rrd crontab (lpar2rrd on Virtual Appliance, it might already exist there)
    $ crontab -e
    # Fujitsu ETERNUS
    0,5,10,15,20,25,30,35,40,45,50,55 * * * * /home/stor2rrd/stor2rrd/ > /home/stor2rrd/stor2rrd/load_eternusperf.out 2>&1
    Assure there is already an entry with the GUI creation running once an hour in crontab
    $ crontab -e
    # STOR2RRD GUI (just ONE entry of must be there)
    5 * * * * /home/stor2rrd/stor2rrd/ > /home/stor2rrd/stor2rrd/load.out 2>&1
  • Let run the storage agent for 15 - 20 minutes to get data, then:
    $ cd /home/stor2rrd/stor2rrd
    $ ./
