Cisco UCS B22 Blade Server Installation and Service Note

OL-27513 -01

Installing and Removing a Blade Server Hard Drive

There are up to 2 front-accessible, hot-swappable, 2.5-inch drives per blade. An LSI 2002 RAID

controller is embedded in the motherboard (a Cisco exclusive and not separately replaceable) and it

supports RAID 0 and 1. You can remove blade server hard drives without removing the blade server from

the chassis. All other component replacement for a blade server requires removing the blade from the

chassis. Unused hard drive bays should always be covered with cover plates (N20-BBLKD) to assure

proper cooling and ventilation. The chassis is omitted from illustrations here to simplify the drawing.

Caution To prevent ESD damage, wear grounding wrist straps during these procedures and handle modules by

the carrier edges only.

Note If you ever need to move a RAID cluster from one server to another, both the old and new servers for the

cluster must use the same LSI controller. For example, migration from a server with an LSI 1064E to a

server with an LSI MegaRAID is not supported. Migrating a RAID cluster from a B200 M1 or M2 to

this server is not supported.

Replacing an HDD or SSD with a drive of the same size, model, and manufacturer generally causes few

problems with UCS Manager. If the drive being replaced was part of a RAID array we recommend using

a newly ordered drive of identical size, model, and manufacturer to replace the failed drive. Cisco

recommends following industry standard practice of using drives of the same capacity when creating

RAID volumes. If drives of different capacities are used, the useable portion of the smallest drive will

be used on all drives that make up the RAID volume. Before upgrading or adding an HDD to a running

system, check the service profile in UCS Manager and make sure the new hardware configuration will

be within the parameters allowed by the service profile.

Hard disk and RAID troubleshooting information is in the "Troubleshooting Server Hardware" chapter

of the Cisco UCS Troubleshooting Guide.
