'raid_diagnostic' command, SmartView Monitor, 'cpstat' command and 'snmpwalk' command show "MISSING" state for some harddisks
Several harddisk devices were caught in the same query, which leads to reporting a "MISSING" state.
In the example below, the harddisk device with ID 11:0:0:0 and harddisk device with ID 1:0:0:0 were caught in the same query:
[Expert@HostName]# ls /sys/bus/scsi/devices/
10:0:0:0 11:0:0:0 1:0:0:0 2:0:0:0 9:0:0:0
This can happen after plugging in and out USB devices, or after restarting the LOM card.
