Replacing or Adding a Hard Drive (CRU)

Note - If your server has fewer than four hard drives, the empty drive bays must have hard drive fillers installed to ensure proper air flow and server cooling.

Hard drives for the Sun Fire X4640 server are hot-swappable. You can replace hard drives without powering off the server. A single hard drive failure will not cause a data loss if the hard drives are configured as a mirrored RAID 1 volume. The failed hard drive can be hot-swapped, and when a new hard drive is inserted, the contents are automatically rebuilt from the rest of the array with no need to reconfigure the RAID parameters. If the hard drive was configured as a hot-spare, the new hard drive is automatically configured as a new hot-spare to mirror the data from the good hard drive.

However, if you insert a hard drive that was configured with a RAID volume into a server that did not previously have its hard drives configured with RAID volumes, the existing hard drives in the server are converted to RAID volumes during automatic synchronization and data on the existing hard drives are lost. To avoid this problem, use the LSI Configuration Utility to delete the RAID volume from the hard drive before removing it.

For information about the implementation and configuration of RAID on this server, see LSI BIOS Configuration Utility.
