Note:

While you can apply RAID-level migration at any time, it is 
recommended that you do so when there are no reboots.  
Many operating systems issues I/O operations serially (one 
at a time) during boot.  With a RAID-level migration running, 
a boot can often take more than 15 minutes.

Migrations are allowed for the following RAID levels:

•

RAID 0 to RAID 1

•

RAID 0 to RAID 5

•

RAID 0 to RAID 6

•

RAID 1 to RAID 0

•

RAID 1 to RAID 5

•

RAID 1 to RAID 6

•

RAID 5 to RAID 0

•

RAID 5 to RAID 6

•

RAID 6 to RAID 0

•

RAID 6 to RAID 5

Table 4.3

 lists the number of additional drives required when you change 

the RAID level of a virtual drive.

Follow these steps to migrate the RAID level:

Caution:

Back up any data that you want to keep before you change 
the RAID level of the virtual drive.

1.

On the main WebBIOS CU screen, select a virtual drive.
