Hi MEAB

 

Which RAID controller did you install on your system? Did you wait disk rebuild or check the hard disk status after replacing a disk?

Would you please refer the ServeRAID M controllers Problem Determination and Service Guide page 24 to solve the problem.

Or you can refer to Lenovo System X RAID management tools article landing page for more information.

this msg show that you have offline vd ,and the data on the controller cache can't flush back to its vd. pls try to make sure your vd can be online, then  reboot server , the data will flush back.

 

if there was foreign drive can't import duo to this error and prevent any operation on controller , pls try to discard this cache, and import the foreign again. 

 

(discard means the data on the controller cache will be lost). 

 

>>> 
To clear pinned cache go to F1 --> "System Settings" --> "Storage" --> select controller --> "Main Menu" --> "Controller Management" --> "Advanced Controller properties" --> "Cache and Memory" and try to discard the cache using "Discard Preserved Cache" option (Note: it will exists only if the Preserved Cache is set to "yes")
