EMC VNX Storage: Contiguous Free Capacity in RAID Groups
|Distribution:||official part of Check_MK|
|Supported Agents:||EMC VNX|
Checks the Usage of RAID Groups in an EMC VNX storage system. In contrast to
the Check emcvnx_raidgroups.capacity this check rates only the biggest
free contiguous group of unbound segments as "free". Fragmented space is
rated as used.
The Check uses the check logic of the df check, so for configuration parameters
and examples please refer to the man page of df.
The information is retriefed by the special agent agent_emcvnx which uses
EMC's command line tool naviseccli. Capacity is retriefed in blocks. For
calculation of size in MB the check assumes a blocksize of 512 Bytes.
The RAID Group ID.
One service is created for each RAID Group listed in the agent output.
