## Symptoms

- * Output of "*raid_diagnostic* " command shows "`State:MISSING`" for one of hard disks.

  *Example*:

  ```
  
  [Expert@HostName]# raid_diagnostic
  Raid status:
  VolumeID:0 RaidLevel: RAID-1 NumberOfDisks:2 RaidSize:465GB State:OPTIMAL Flags:ENABLED
  DiskID:0 DiskNumber:0 Vendor:ATA      ProductID:WDC WD5003ABYZ-0 Revision:01.0 Size:465GB State:MISSING Flags:NONE
  DiskID:1 DiskNumber:1 Vendor:ATA      ProductID:WDC WD5003ABYZ-0 Revision:01.0 Size:465GB State:ONLINE Flags:NONE
  [Expert@HostName]# 
  ```

* Output of "*cpstat os -f raidInfo*" command shows:

  * In "Volume list" table":  
    Volume state = "0" (meaning *optimal* )   

  * In "Disk list" table:  
    Disk state = "1" for one of hard disks (meaning *missing*)
* SmartView Monitor shows:

  * In "RAID Volumes" table:  
    State = "*Optimal* "   

  * In "RAID Volume Disks" table:  
    State = "*Missing*" for one of hard disks

* Output of "*snmpwalk -c \<community\> -v 2c localhost 1.3.6.1.4.1.2620.1.6.7.7.2.1.9 1.0* " command on the problematic machine returns "1" for one of hard disks (meaning *missing*):

  `SNMPv2-SMI::enterprises.2620.1.6.7.7.2.1.9.1.0 = INTEGER: 1`

## Cause

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
[Expert@HostName]#
```

This can happen after plugging in and out USB devices, or after restarting the LOM card.
