Raid5 Start schlägt fehl

**Hubert** · 12-06-17, 08:13

Hallo zusammen,

ich wollte am Wochenende zu unserem bestehenden RAID5 (6 Platten) eine Hot Spare Platte konfigurieren. Als ich eine Platte dazu aus dem RAID entfernen wollte, hat die Maschine den gesamten RAID aufgelöst. Jetzt läuft die Maschine ohne entsprechenden Schutz. Wenn ich über SST oder DST RAID5 neu sterten will, bekomme ich diese Fehlermeldung:

Code:

                  Start Device Parity Protection Failed             
                                                                    
 There are no disk units eligible for the selected operation        
 due to one or more of the following reasons:                       
                                                                    
 o  All the device parity capable disk units are already device     
    parity protected.                                                                 Nein
 o  Maximum number of arrays exceeded.                                     Nein 
 o  An IOA is in a condition that makes the disk units attached to  
    it read/write protected.  Examine the 'Product activity log'    
    for any reference codes that are logged for the IO subsystem    
    and follow the appropriate procedure for the reference code to  
    correct the problem, if necessary.                                          Nein
 o  Not all disk units attached to an advanced function IOA have    
    reported to the system.  Retry the operation.                           ????
 o  All the disk units in a parity set must be the same capacity    
    with a minimum number of either 3 or 4 units, and a maximum     
    number up to 18 units (depending upon the type of adapter)      
    in the resulting parity set.                                                      OK
 o  The type/model of the disk units is not supported for the         
    requested operation.                                                              War ja vorher
 o  If starting device parity protection beyond the                   
    limited paging environment, all units in the                      
    array must be non-configured.  Otherwise device parity            
    protection must be started in the limited paging                  
    environment.                                                                          *
 o  The device parity units are under a type of IOA which             
    requires an auxiliary write cache adapter.

* heißt das, RAID5 kann nur im eingeschränkten System gestartet werden?

Die Disk Konfiguration sieht so aus:

Code:

                     Display Disk Configuration Protection                    
                                                                              
           Serial                     Resource                      Hot Spare

        3  Y680JLX4R7ZC    433D  050  DD003      Unprotected             N    
        4  Y680JLX4YHAC    433D  050  DD004      Unprotected             N    
        5  Y680JLX3K21C    433D  050  DD006      Unprotected             N    
        6  Y680JLX4R22C    433D  050  DD002      Unprotected             N

Kann mir jemand verraten, wo es hakt?

Herzlichen Dank im Voraus
