Yesterday our NSS6000 with 4 x 750Gb Sata drives started running very slowly..

we saved config onto flash USB and performed reboot from admin maintainence panel.

the unit came back up, but under storage it says :

LabelRAID LevelSpareSizeStatusAction

I press start and get :

Failed to start RAID
Please check that all components are present

.. all drives are present, and i can inventory them and they are all online.. there are no errors in the logs..

i have now rebooted the unit about 4 times.. all times exactly the same.

I even read on here and reset to factory then restored configuration from USB and rebooted.. no difference..

Our system is running :

Firmware Version1.14-20 (Thu, 18 Dec 2008 11:09:47 +0000)
Hardware RevisionV03
Last Firmware UpgradeThu Dec 18 22:09:47 2008

can anyone give me any ideas how to get this going again without losing data ?

I've got exactly the same problem today, with an NSS4000.

4 x SATA 2Tb WDC-WD20EADS-00S in a RAID5 array.

I received an email alert:


Software RAID monitor detected an array in a degraded state.

Degraded Mode Management is disabled, this array will continue to run in degraded mode.


I checked the web interface and noticed the array was "Stopped". All 4 disks are PASSED and ONLINE.

When i want to start, i also get the message:


Failed to start RAID
Please check that all components are present


Any idea what's going wrong and how to solve this issue quickly without loosing any data ?

(We have backup, but not for the 6Tb of data...)

Thanks in advance.

No, i didn't found any solution and Cisco support was useless. The only thing they were able to say was to rebuild a new array and restore from backup...

So i lost all data for which i didn't had any backup.

The same problem occured 4 times on 3 different NSS4000 devices... So i recently throw them away to finally buy real professional devices (definetely not Cisco ones !).
