Notes on the Handling of Hard Disk Drives of RAID 1 Configuration
If hard disk drives configured to RAID 1 by using HostRAID are used by a CPU blade with the
HostRAID set to [disable], the data stored in the hard disk drives will be damaged.
Take sufficient note when hard disk drives configured to RAID 1 by HostRAID are connected to
another CPU blade.
If it is necessary to make sure that HDDs are subject to the RAID 1 configuration, follow the
procedure below:
