With the S8 generation of Fujtitus RX300/200 servers, which use the iRMC S4 ,Fujitsu implementent the ability to poll SNMP-data from the BMC (iRMC). To enable the ability to poll data the BMC has to be flashed with an up to date Firmware version and SNMP-polling has to be enableed in the iRMC-web-GUI. I’ve tested it with 7.69F from Dec. 2014 .
The first shippings of the rx300/200 servers came with an older firmeware version which did not implment the needed Fujitsuu MIBs to query HW-status (see http://manuals.ts.fujitsu.com/file/11470/irmc-s4-ug-en.pdf Page: 18 for details about the supported MIBs).
The problem is, that there is no possibility to query the status of the Raid controller and its disks via SNMP (or I haven’t found it till now) but it’s displayed on the iRMC web-GUI. So I wrote a script which extracts the useful informations (controller status, disk status + details and logical drive status) from the web-interface.
Atm. it’s just an alpha release but I’ll modify the script to be used by Zabbix for an auto discovery and push all the data into Zabbix:
