EMC VNX Storage: Status and I/O of Disks
Reports the status and the I/O rate of a disk in an EMC VNX storage system.
Returns OK if the state of a disk is "Unbound" or "Hot Spare Ready" or
"Enabled" or "Ready", the number of Hard Read Errors is 0 and the number
of Hard Write Errors is 0.
Returns WARN if the state of a disk is "Rebuilding", the number of Hard
Read Errors is 0 and the number of Hard Write Errors is 0.
CRIT is returned otherwise.
I/O rates (in Bytes/sec) are just informational and do not trigger any state
other than OK
The information is retriefed by the special agent agent_emcvnx which uses
EMC's command line tool naviseccli.
If you always get Read: 0.00B/s, Write: 0.00B/s and you think this are not the correct values, please note: Reporting of these data must be turned on at the storage by a command like setstats -on
Consists of bus ID, enclosure ID and disk ID as returned by the agent.
E. g. "1/1 Disk 9"
Automatically configures one check for every disk listed in the agent output.
