Duplicate Flash Disks Entries After Several Months (Doc ID 1469385.1)

Last updated on JUNE 25, 2012

Applies to:

Oracle Exadata Hardware - Version 11.2.1.2.1 to 11.2.3.1.1 [Release 11.2]
Oracle Exadata Storage Server Software - Version 11.2.1.2.1 to 11.2.3.1.1 [Release 11.2]
Linux x86-64

Symptoms

After flashdisk replacements, duplicate entries for flashdisks are still present after months. Duplicate entries has appeared in MS files after the replacement moment. They have never been cleaned after 7 
days as expected.
  
 
 
There are duplicate entries for the same lun name "1_0". Status for one of them is normal but the other is not present. Those normally can be ignored when disks with status "not present". After a device 
replacement, old entry is kept for another 7 days. This is known as expected behaviour. 
The reason for unknown / not present state is that there are two entries for each phsyical disk. This is a known issue that has been fixed in 11.2.1.3. Old entries are kept for diagnostic purposes for 7-days.
