To avoid this issue, ensure that the service profile you associate with the server contains the identical local
disk configuration policy as the original service profile before the migration and does not include the Any
Configuration mode.
Configure RAID Settings in Local Disk Configuration Policy for Servers with MegaRAID Storage Controllers
If a blade server or integrated rack-mount server has a MegaRAID controller, you must configure RAID
settings for the drives in the Local Disk Configuration policy included in the service profile for that server.
If you do not configure your RAID LUNs before installing the OS, disk discovery failures might occur during
the installation and you might see error messages such as “No Device Found.”
Do Not Use JBOD Mode on Servers with MegaRAID Storage Controllers
Do not configure or use JBOD mode or JBOD operations on any blade server or integrated rack-mount server
with a MegaRAID storage controllers. JBOD mode and operations are not intended for nor are they fully
functional on these servers.
Maximum of One RAID Volume and One RAID Controller in Integrated Rack-Mount Servers
A rack-mount server that has been integrated with Cisco UCS Manager can have a maximum of one RAID
volume irrespective of how many hard drives are present on the server.
All the local hard drives in an integrated rack-mount server must be connected to only one RAID Controller.
Integration with Cisco UCS Manager does not support the connection of local hard drives to multiple RAID
Controllers in a single rack-mount server. We therefore recommend that you request a single RAID Controller
configuration when you order rack-mount servers to be integrated with Cisco UCS Manager.
In addition, do not use third party tools to create multiple RAID LUNs on rack-mount servers. Cisco UCS
Manager does not support that configuration.
Maximum of One RAID Volume and One RAID Controller in Blade Servers
A blade server can have a maximum of one RAID volume irrespective of how many drives are present in the
server. All the local hard drives must be connected to only one RAID controller. For example, a B200 M3
server has an LSI controller and an Intel Patsburg controller, but only the LSI controller can be used as a
RAID controller.
In addition, do not use third party tools to create multiple RAID LUNs on blade servers. Cisco UCS Manager
does not support that configuration.
Number of Disks Selected in Mirrored RAID Should Not Exceed Two
If the number of disks selected in the Mirrored RAID exceed two, RAID 1 is created as a RAID 10 LUN.
This issue can occur with the Cisco UCS B440 M1 and B440 M2 servers.
B420 M3 Server Does Not Support All Configuration Modes
The B420 M3 server does not support the following configuration modes in a local disk configuration policy:
• No RAID
• RAID 6 Striped Dual Parity
In addition, the B420 M3 does not support JBOD modes or operations.
