Figure 162 Switching the controller to JBOD mode 

 

 

5. 

Select 

Confirm

 to enable the specified mode, select 

Yes

 and then press 

Enter

. 

 

 

CAUTION:

 

When switching the storage controller to JBOD mode, you can also change logical drives 
managed by the controller to JBOD mode at the same time. Be careful that data might be 
cleared for logical drives that do not support JBOD mode once you switch the mode. As a best 
practice, before switching the mode of an LSI storage controller, change the drive state to 

Unconfigued Good

. For example, logical drives in RAID 5, RAID 6, RAID 50, or RAID 60 

managed by RAID-LSI-9560-LP-8i-4GB storage controller do not support JBOD mode and will 
be cleared if you switch their mode. For more information, see the screen prompt.
